营运能力的分析外文中英文翻译外文翻译原文 Operation ability analysis Material Source: China＇s securities nets 05/17/2020 Author:Techever Operation ability fully utilize existing resources to create social wealth ability, can be used to evaluate the enterprise to its own resources utilization and operating activities ability. Its essence is to as few as possible resources occupation short turnover time, produce as many products, create as many sales revenue, and to achieve this goal, we must improve enterprise＇s operation ability level. Operation ability is the assets of the enterprise turnaround to measure the efficiency of the utilization of assets enterprises. The index reflects assets turnover rate have inventory turnover, liquid assets turnover rate, total asset turnover. The faster turnaround speed, it shows that the enterprise of assets into business links, forming the faster the cycle of revenue and profit more short, business efficiency is higher. Operation ability refers to the enterprise asset turnover operation ability, usually can use total asset turnover, fixedasset turnover, flow asset turnover, inventory turnover and accounts receivable turnover these five financial ratios to enterprises＇ operating capacity for layered analysis. Operation ability analysis can help investors understand enterprise business conditions and operating management level. With our su ning electric equipment (BBS) (market, for example, 002024) to introduce how to enterprise＇s investors operating capability analysis. Total asset turnover is to show enterprise sales income and total assets of the ratio of average balance. Suning 2020 sales revenue for 91.1 billion yuan, average total assets of 14 million yuan; 2020 sales income increased to 160.4 billion yuan, the average total assets is increased by 2.3 times, reached 31.9 million yuan. Due to the growing rate of total assets than the sales income increase, total asset turnover down to 5 by lead. The rate of decline in 2020 with suning opened the new mass are directly related. In order to complete the “national cloth nets“ thestrategic pattern, suning in 2020 at 65, a new store new landed 20 cities, and the original logistics, service system of radiation radius is limited, so su ning to makes lots of management platform, in order to support the construction of the urbanconstruction in the same after other stores of logistics and management. This makes su ning expansion strategy initial cost of relatively high. Current assets turnover is enterprise＇s sales income and liquidity ratio of average balance. Through this ratio analysis, we can further understanding of enterprise in the short term operation ability changes. From statements that su ning 2020 sales income nearly 1.6 billion yuan, growth rate, while the average flow rate reached more than doubled assets. The liquidity didn＇t bring the same margin large increase of sales income growth, so current assets turnover in 2020 7.36 dropped by the 2020 5.61, explain the efficiency in the use of su ning liquid assets declined. Fixed asset turnover is mainly used for analysis of fixed assets such as factory buildings, equipment, the ratio of the utilization efficiency of the higher and higher, explain utilization, management level, the better. If the fixed asset turnover compared with industry average low, then explaining enterprise of fixed assets utilization is low, might affect the enterprise profitability. It reflects enterprise asset utilization degree. Fixed asset turnover ratio = sales revenue/average net value of fixed assets The average net value of fixed assets = (initialequity + final equity) voting 2 Enterprise inside certain period advocate business wu income with average net current assets ratio of total asset utilization, is appraise enterprise another important indexes. It reflects the enterprise liquid assets turnover rate from enterprise all assets, liquidity of the strongest in current assets Angle of enterprise assets utilization efficiency, in order to further analyze the quality of enterprise assets reveals acoustics major factor. Current assets turnover means certain period for a year) (usually the main business income and total migrant assets ratio of the average balance.therefore, can through to inventory turnover and accounts receivable further analysis of flow asset turnover ratio changes. Suning in stock sales primarily, therefore, accounts receivable accounted for only the liquidity, and inventory 50% 4.75%. Inventory turnover refers to enterprises and inventory cost of sales average balance ratio. For real estate industry inventory turnover is a very key indicators, real estate industry is very special. Usually, inventory turnover is the sooner the better, and real estate industry inventory quantity bigger, the slower the turnover that the strength of the company is the more abundant. Other industry＇s inventory turnover for six or seven times a year of general level, in contrast, in the real estate industry a year about a second, if in six or seven times a year inventory turnover for real estate industry as the company is tiny companies, with a powerful real estate stocks, inventory turnover are very low, because must keep a lot of land reserves, land reserve is his inventory, the houses built yet form sales belong to assets range, depend on these achieve sales.Inventory turnover condition can also be expressed with inventory, namely said days once inventory turnover the time required that the shorter days, the faster inventory turnover. Suning 15.05 inventory turnover in 2020 for 2020, this ratio dropped to 10.33. Accordingly, inventory turnover days from 24 days extended to 35 days. Inventory liquidation speed decreased obviously, explain suning sales ability may exist problems down or inventory excess. Accounts receivable turnover refers to the enterprise certain period income and accounts receivable credit average balance ratio. It reflects the company obtained the account receivable from the right to withdraw money, can be converted into cash needed the length of time. Accounts receivable turnover can be used to estimate the accounts receivable convertedspeed and management efficiency. Recovery quickly can save money, also shows that enterprise credit situation is good, not easy loss of bad happened. Generally believe that the higher the turnover of the good.This index measure enterprise accounts receivable into cash speed. Because credit sales income can＇t easily get, in practice used more sales income is calculated alternative credit income. Suning customers is mainly individual consumer to both clear of money and goods, trading on the basis of the account receivable credit income proportion is very small, so the sales income data obtained by receivable turnover is very high. In general, the higher the ratio of enterprises that enterprise collection receivable and the faster, can reduce the loss of bad, and liquidity strong, enterprise＇s short-term solvency will also strengthen, in some extent could compensate for the current ratio low adverse impact. If the enterprise receivables turnover is too low, then explaining enterprise collection receivable inefficient or credit policy very loose, affect the enterprise use of the capital and capital normal turnover. On real estate enterprise operation ability of financial analysis framework can mainly from three aspects: building management ability index, accountsreceivable turnover and working capital turnover rate. In these three respects based on real estate enterprise combining the characteristics, the selection of the appropriate financial index on real estate enterprises＇ operating capability evaluation. This paper puts forward the analysis framework of general applicability, for real estate enterprises and other enterprises in the operation of the managers do provide quantitative basis for decision-making and analysis methods. Through the case analysis can be found that, because the influence of assets turnover rate, total assets yield level but not necessarily advocate business wu income consistent with gross margin. And commercial real estate and industrial real estate, residential real estate than sex where profit margins, so vanke＇s sales income margin increased year by year, but despite highest when still about 41%, but the lujiazui, and the land is provided income can be as high as 80% gross margin, cofco property of materials processing income also can achieve 75% gross margin. From the trend, the incomes of the three companies are in growth state gross margin. But because the operating cash flow is low, the efficiency high profit margins of the lujiazui and cofco real estate but show low on total assets. Three real estate enterpriseoperations in there is a common problem, namely the working capital turnover rate is too slow. Operation ability of the enterprise of the scale of operations and different difference were real estate enterprise can cause inventory turnover rate and working capital turnover rate is different. Residential property turnover rate sex than commercial real estate and industrial real estate, so vanke faster the inventory turnover faster than lujiazui, cofco property because small in scale, the turnover rate close to YuWanKe. But in recent years due to land prices continue to rise, real estate enterprises have been through a lot of store, extend the project development period and so on the way to getting the higher profit margin. Thus the current real estate enterprises in our country there are a large amount of inventory turnover, slow ills. 译文营运能力的分析资料来源：中国证券网 05/17/2020 作者：Techever 营运能力是充分利用现有资源创造社会财富的能力，可以用来评价企业对其拥有资源的利用程度和营运活动能力。

这意味着工业部门在其内部拥有处理原材料和制造货物的业务。
这也被称为第二产业或制造业。
我选择的企业是科尔集团。
科尔集团适应行业/次领域内是因为这是一个建筑公司，在成品即翻砖建筑原材料的交易。
For this assignment we have been asked to research the Industry sector, choose a business within that sector, and then analyse and evaluate the business we have chosen from an operations manager point of view.First we must know what the Industry sector is. Aording to oxford dict ionary the word industry means ‘Economic activity concerned with the processing of raw materials and manufacture of goods’ (Oxford Dictionary. xx).This means that the industry sector have businesses within it that deal with the processing of raw materials and manufacture of goods. This is also called the secondary sector or manufacturing sector.In xx the UK manufacturing sector generated ￡140bn in revenue this is 11% of the UK total economy. This sector also employed 2.6 million people which equals out to be 8% of the UK workforce. The whole sector itself is spilt upinto 14 different industries by the government whichinclude textiles and chemicals (BIS. xx).The business I have chosen is Kier Group plc. Thereason that Kier Group plc fit within the Industrysector/secondary sector is because this is a construction firm that deals with turning raw materials in a finished products i.e. turning bricks into buildings.Kier Group plc offers their services to the public and private sectors, these servic es include ‘civil engineering, mining, mechanical & electrical design and installation… and 3D modeling’ (Kier Construction. xx). An example of public sector customer would be the Northampton Borough Council in creating their new ￡7 million North Gate Bus Station (Northampton Chronicle & Echo. xx). An example of a private sector customer would be Network RailInfrastructure Ltd, as Kier Group plc did the King’s Cross Station roof refurbishment (Kier Group. xx). Kier Groupplc’s clients are often other busin ess or large public bodies such as Councils due to their ability and proventrack record with multi-million pound contracts that they are asked to do or win the contracts against other petitors such as Balfour Beatty PLC. Kier Group plc operate on a global scale however some parts within Kier Group plc work within the U.K.Any organisation can be shown as multiple ofinput/output diagrams in a hierarchy format. At the bottom of this hierarchy would be the customer’s needs being transformed into consumer satisfaction (Muhlemann, A. Oakland, J. Lockyer, K. 1993). As every business is made with the customer in mind even if the businesses overall goal could be to maximise profits they still need the customer. However other input/output diagrams in the hierarchy differ from business to business. As a car mechanic shop wouldn’t use the same ways to satisfy consumers as a bridal dress shop would.As Kier Group plc deals with construction it has a specific inputs and outputs. Five inputs of Kier Group plc would be skilled labour, high quality equipment, energy, building materials, and basic project designs. Three outputs of the pany would be buildings, infrastructure, and recycled materials.Skilled labour is an input for Kier Group plc because to be able operate as a building business they would need skilled labour.This is because the jobs that the business could be doing may have a high risk of doing lots of damage not just money’s terms but in personnel terms as well. This would also be beneficial to the business as it could lead to being more productive due to the skilled labour however it would be costly hiring someone that’s highlyskilled or even over skilled for the job rather than someone who could just about do the job. But in the pany’s overview they want to offer clients ‘world-class solutions’ (Kier Group. xx)which suggests that the highly skilled labour would be used.High quality equipment is would be a specific input for Kier Group plc due to the nature of the job that the business gets inquired about. These can be very plex jobs such as the Kings Cross Station roof refurbishment. Not only did they refurbish an iconic building roof, thestation had to stay open with thousands of people walking underneath the building work. This shows the high quality equipment would be needed as an input.The reason that energy is needed as an input as the business would be using puters to design projects and also it would be needed to power equipment on site. It is a needed input in this business.Building materials are a vital input to the business as they are needed to get to the final product. Without these, the business would not be able to run as a construction business. Kier Group plc need to start from a basic project design to be able to make what the customer want like the business to make. That’s is why basic project designs is a needed input for the business. As Kier Group plc have architects that would design the final product from thesebasic project designs whether it would be a finish building or a new part for railways.A specific output for Kier Group plc would be buildings as this is the main product/good that the business produces. They way in which this would be produced from inputs would be via project process. Project production is a type of production that has low volume of products but high variety between each one. This means that each new project would be different from the last using different materials with different quantities. They also have to be made in a fix location which is one of the classifications of a project production. During the production of each building uses a mixed process technology it uses manual and mechanised.This means that during the production of each buildingthere are parts which are done via hand with no machinery and there are parts where machinery is utilised but under the control of humans (Evens, J. 1993).Infrastructure in another output of Kier Group plc asit doesn’t only make buildings it also builds roads,railway parts and much more which is a vital part in the UK’s infrastructure. These would also be produced in a project production as each part of infrastructure they make would be different from another part.One other output the Kier Group plc produces are recycled materials. Kier Group plc has a recycling servicewhich is used in many counties. Recycled materials go through many processes. It is made via continuous flow production as it has a high product volume, there’s some although not much product variety. During the processes the recycled material goes though there are a high number of automated and specialised equipment that does a large amount of the work. There is also labour that take out any rubbish that can’t be recycled or shouldn’t be in that particular recycling line this doesn’t require high skills. The reason that it is not a Mass production is that there isn’t any variety between each product at the end (Evens, J. 1993).The demand for the products and services the Kier Group plc produce usually depend on the economic state of the country but there are also other factors the affect the demand for the business. These factors include: globalisation, demand for more sustainable construction, demographic changes and increasing importance fortechnology use in construction.The demand for the products and services that Kier Group plc produce usually depend on the economic state ofthe country but there are also other factors the affect the demand for the business. These factors include: globalisation, demand for more sustainable construction,demographic changes and increasing importance fortechnology use in construction.The reason that the state of the economy affects the demand for Kier Group plc’s products and services is because buildings and infrastructure is capital which helps boost long term growth. These are the first things that are cut if the economy was to go into decline. When the recession hit in xx aording to House of Commons there was a fall by 6.2% in gross value added for the construction industry, followed by a 7.9% fall in GVA, then an increase by 1.1% in xx, and then followed by a 6.0% drop in GVA during the double dip recession (Rhodes, C. xx). This data shows there is a correlation between the construction industry including Kier Group plc and the state of the economy.The demand for more sustainable construction also impacts the stability of the demand of Kier Group plc’s products and services because if the business doesn’toffer the right amount of sustainable construction or by offering ‘green’ alternatives they may lose customers and clients. As new legislation is soon to be ing into action due to the UK’s recent air pollution issues this would mean a possible overhaul of more carbon producing processes. However to overe this Kier Group plc currently generates10% of its revenue by using recycled material, low energy alternatives and more sustainable materials (Fry, C. xx) Every business needs demand to be able to sell its good and/or services however you need to be able to have enough capacity to meet this demand. Capacity planning is vital in operations strategies. Capacity is best when it around 75-90% utilised. Having capacity between these levels means that you should still be able to cope with new clients without having to turn larger clients down and also you won’t be running with excess capacity. Excess capacity is a large cost on businesses and may lead to layoffs and department closures (Hill, T. 1991)There are 3 different strategies that a business can use to plan capacity to meet demand. These policies are: Matching Capacity with Demand, Excess Capacity, and Capacity Shortage Policy. Matching capacity with demand means that the business tries to keep as close to demand as they possibly can.This policy means that it sometimes has excess capacity in which it has the ability to get more clients or customers. However it also means there is a shortage of capacity. During these times a business would have to subcontract out work to get a short term increased capacity or they would lose sales this could e from poor quality of work from being rushed to pete work.A Capacity Shortage Policy is when there is a gap between the demand and the capacity where demand is always higher than capacity. As there is a high capacityutilisation this means there is a strong return on investment. This type of policy is usually best for goodsor services that usually relate to status or are in fashion. This would mean that there is a high capacity utilisation which in turn leads to a strong return on investment. For example the iPhone 4 White. When it came out it was being sold quicker than it was being made.The way that Kier Group plc plan their capacity is by a strategy called Excess Capacity Policy (Fry, Colin. xx). This policy means that the business has a goal of maintaining enough capacity to be able to meet with demandor to reduce the chance of not meeting demand. Althoughthis policy can lead to higher costs than the other two polices it is the best policy for this business. This is because the business does not know if they are going to win a bid for a client so there needs to be spare capacity in case they do win the bid. As large construction businesses get invited to present their bid on large projects so the business always need to be prepared for these invites.Kier Group plc could better utilise operations management to counter some of the challenges that it has in the ever changing market place. It could utilise LeanOperations more this is because there is going to be more legislation regarding reducing waste and carbon footprint. It’s better to be proactive to changes in legislation than to be reactive as it shows the business has a strong CSR which customers and clients look for.Lean Operations is minimising the amount of waste there is in order to operate quicker, produce higher quality work and also to operate at low costs. The reason that lean operation is suited for Kier Group plc is because in the lean approach there is a focus on producing only when there is a need to produce, this does mean there is a lower capacity utilisation however this fits in well with the Excess Capacity Policy has the business already is implementing.Some of the techniques that could be used in lean operations for the business could be JIT supply and Total Involvement. JIT supply means just in time supply. This means that you wouldn’t receive materials until you need those materials (Hill, T. 1987). This would be useful in the business because it means there wouldn’t been material they do n’t need wasting space in a construction site. For example the wouldn’t need a road tarmaer when the drainage is still 3 days away from being pleted not only could it be wasting space it could be in the way of workers increasing the distance from the mater ials they’re using to the placewhere they need to use them. If 10 workers had to go anextra 20 seconds out of their way whilst this tarmacer was3 days early and each worker had to do this trip 40 times a day that adds an extra 400 minutes on their travel overall on the 3 days the tarmacer was there. With JIT supply the tarmacer would arrive on the day it was needed saving the 400 minutes which could have been wasted.Total involvement is when everyone within the businessis aware of the lean approach of the business. If everyoneis doing it, it would bee second nature to abide by the5S’s of lean operations. These are sort, straighten, shine, standardise and sustain (Muhlemann, A. Oakland, J. Lockyer, K. 1993)Sort means to eliminate what is not needed and to keep whatever is needed in the production of goods. Straighten means to place tools and equipment is such a way that is it easily aessible as lots of time is spent looking for tools that have been misplaced. Shine is to keep things clean and tidy. This could lead to less injuries due to slipping over dirt or waste packaging. Standardise means to keep to a certain level of cleanliness and sustain is to keep to this standardisation throughout each product life cycle.These methods of lean operations keep Kier Group plc near the top of the construction market as they would beless wasteful, operate with lower costs and also could leadto a better workforce from total involvement as everyone would feel they are impacting the businesses performance.。

激进的营运资本管理政策对企业盈利能力的影响外文文献翻译
文献信息：文献标题：Impact of Aggressive Working Capital Management Policy on Firms’ Profitability（激进的营运资本管理政策对企业盈利能力的影响）国外作者：Mian Sajid Nazir，Talat Afza文献出处：《The IUP Journal of Applied Finance》,2009,Vol.15,PP19-30 字数统计：英文2669单词，14456字符；中文4407汉字外文文献：Impact of Aggressive Working Capital Management Policyon Firms’ ProfitabilityIntroductionThe corporate finance literature has traditionally focused on the study of long-term financial decisions, particularly investments, capital structure, dividends or company valuation decisions. However, short-term assets and liabilities are important components of total assets and need to be carefully analyzed. Management of these short-term assets and liabilities warrants a careful investigation since the working capital m anagement plays an important role in a firm’s profitability and risk as well as its value (Smith, 1980). Efficient management of working capital is a fundamental part of the overall corporate strategy in creating the shareholders’ value. Firms try to keep an optimal level of working capital that maximizes their value (Deloof, 2003; Howorth and Westhead, 2003 and Afza and Nazir, 2007).In general, from the perspective of Chief Financial Officer (CFO), working capital management is a simple and straightforward concept of ensuring the ability of the organization to fund the difference between the short-term assets and short-term liabilities (Harris, 2005). However, a ‘Total’ approach is desired as it can cover all thecompany’s activities relating to vendor, cu stomer and product (Hall, 2002). In practice, working capital management has become one of the most important issues in the organizations where many financial executives are struggling to identify the basic working capital drivers and an appropriate level of working capital (Lamberson, 1995). Consequently, companies can minimize risk and improve the overall performance by understanding the role and drivers of working capital management.A firm may adopt an aggressive working capital management policy with a low level of current assets as a percentage of total assets, or it may also be used for the financing decisions of the firm in the form of high level of current liabilities as a percentage of total liabilities. Excessive levels of current assets may have a negative effect on the firm’s profitability, whereas a low level of current assets may lead to a lower level of liquidity and stockouts, resulting in difficulties in maintaining smooth operations (Van Horne and Wachowicz, 2004).The main objective of working capital management is to maintain an optimal balance between each of the working capital components. Business success heavily depends on the financial executives’ ability to effectively manage receivables, inventory, and payables (Filbeck and Krueger, 2005). Firms can reduce their financing costs and/or increase the funds available for expansion projects by minimizing the amount of investment tied up in current assets. Most of the financial managers’ time and efforts are allocated towards bringing non-optimal levels of current assets and liabilities back to optimal levels (Lamberson, 1995). An optimal level of working capital would be the one in which a balance is achieved between risk and efficiency. It requires continuous monitoring to maintain proper level in various components of working capital, i.e., cash receivables, inventory and payables, etc.In general, current assets are considered as one of the important components of total assets of a firm. A firm may be able to reduce the investment in fixed assets by renting or leasing plant and machinery, whereas the same policy cannot be followed for the components of working capital. The high level of current assets may reduce the risk of liquidity associated with the opportunity cost of funds that may have been invested in long-term assets. Though the impact of working capital policies onprofitability is highly important, only a few empirical studies have been carried out to examine this relationship. This study investigates the potential relationship of aggressive/conservative policies with the accounting and market measures of profitability of Pakistani firms using a panel data set for the period 1998-2005. The present study is expected to contribute to better understand these policies and their impact on profitability, especially in emerging markets like Pakistan.Research MethodologyVariables Used in the StudyThis study uses aggressive investment policy as used by Weinraub and Visscher (1998), who analyzed working capital policies of 126 industrial firms in the US market. Aggressive Investment Policy (AIP) results in minimal level of investment in current assets versus fixed assets. In contrast, a conservative investment policy places a greater proportion of capital in liquid assets with the opportunity cost of less profitability. If the level of current assets increases in proportion to the total assets of the firm, the management is said to be more conservative in managing the current assets of the firm. In order to measure the degree of aggressiveness of working capital investment policy, the following ratio was used:where a lower ratio means a relatively aggressive policy.On the other hand, an Aggressive Financing Policy (AFP) utilizes higher levels of current liabilities and less long-term debt. In contrast, a conservative financing policy uses more long-term debt and capital and less current liabilities. The firms are more aggressive in terms of current liabilities management if they are concentrating on the use of more current liabilities which put their liquidity on risk. The degree of aggressiveness of a financing policy adopted by a firm is measured by working capital financing policy, and the following ratio is used:where a higher ratio means a relatively aggressive policy.The impact of working capital policies on the profitability has been analyzed through accounting measures of profitability as well as market measures of profitability, i.e., Return on Assets (ROA) and Tobin’s q. These variables of return are calculated as:Tobin’s q compares the value of a company given by financial markets with the value of a company’s assets. A low q (between 0 and 1) means that the cost to replace a firm’s assets is greater than the value of its stock. This implies that the stock is undervalued. Conversely, a high q (greater than 1) implies that a firm’s stock is more expensive than the replacement cost of its assets, which implies that the stock is overvalued. It is calculated as:where Market Value of Firm (MVF) is the sum of book value of long plus short term and market value of equity. Market value of equity is calculated by multiplying the number of shares outstanding with the current market price of the stock in a particular year.Control VariablesIn working capital literature, various studies have used the control variables along with the main variables of working capital in order to have an apposite analysis of working capital management on the profitability of firms (Lamberson, 1995; Smith and Begemann, 1997; Deelof, 2003; Eljelly, 2004; Teruel and Solano, 2005 and Lazaridis and Tryfonidis, 2006). On the same lines, along with working capital variables, the present study has taken into consideration some control variables relating to firms such as the size of the firm, the growth in its sales, and its financial leverage. The size of the firm (SIZE) has been measured by the logarithm of its totalassets, as the original large value of total assets may disturb the analysis. The growth of firm (GROWTH) is measured by variation in its annual sales value with reference to previous year’s sales[(Sales t –Sales t –1)/Sales t –1]. Moreover, the financial leverage (LVRG) was taken as the debt to equity ratio of each firm for the whole sample period. Some studies, like Deloof (2003) in his study of large Belgian firms, also considered the ratio of fixed financial assets to total assets as a control variable; however, this variable cannot be included in the present study because of unavailability of data, as most of the firms do not disclose full information in their financial statements. Finally, since good economic conditions tend to be reflected in a firm’s profitability (Lamberson, 1995), this phenomenon has been controlled for the evolution of the economic cycle using the GDPGR variable, which measures the real annual GDP growth in Pakistan for each of the study year from 1998 to 2005.Statistical AnalysisThe impact of aggressive and conservative working capital policies on the profitability of the firms has been evaluated by applying the panel data regression analysis. The performance variables (ROA and Tobin’s q) as well as the TCA/TA and TCL/TA along with the control variables were regressed using the SPSS software. The following regression equations are run to estimate the impact of working capital policies on the profitability measures.where,TCA/TA=Total current assets to total assets ratioTCL/TA i=Total current liabilities to total assets ratioROA i=Return on assetsTobin’s q i=V alue of qSIZE i=Natural log of firm sizeGROWTH i=Growth of salesLVRG i=Financial leverage of firmsGDPGR i=Real Annual GDP growth rate of Pakistanα=Intercept; andε=Error term of the modelSample and DataThe sample of the study consists of all non-financial firms listed on the Karachi Stock Exchange (KSE). KSE has divided the non-financial firms into various industrial sectors based on their nature of business. In order to be included in the sample, a firm must be in business for the whole study period. Also, firms should neither have been delisted by the KSE nor merged with any other firm during the whole window period. New incumbents in the market during the study period have also not been included in the sample. Furthermore, firms must have complete data for the period 1998-2005. Firms with negative equity during the study period have also been excluded. Thus, the final sample consists of 204 non-financial firms from 17 various industrial sectors.This study used annual financial data of 204 non-financial firms for the period 1998-2005. The panel data set was developed for eight years and for the 204 sampled firms which produced 1,632 year-end observations. The required financial data for the purpose of the study was obtained from the respective companies’annual reports and publications of State Bank of Pakistan. The data regarding annual average market prices was collected from the daily quotations of KSE.AnalysisTable 1 presents the results of regression model in which the impact of working capital investment policy on the performance measurements has been examined. The F-values of regression models run are found statistically significant, whereas Durbin-Watson statistics of more than 1.8 indicate less correlation among the independent variables of the regressions models. The t-statistics of working capital investment policy is positive and statistically significant at 1% level for Return on Assets and Tobin’s q. The positive coefficient of TCA/TA indicates a negative relationship between the degree of aggressiveness of investment policy and return on assets. As the TCA/TA increases, the degree of aggressiveness decreases, and return on assets increases. Therefore, there is a negative relationship between the relative degree of aggressiveness of working capital investment policies of firms and both performance measures, i.e., ROA and Tobin’s q. This similarity in market and accounting returns confirms the notion that investors do not believe in the adoption of aggressive approach in the working capital management, hence, they do not give any additional weight to the firms on KSE.Table 2 reports regression results for working capital financing policy and the performance measures. The F-value of regression models and Durbin-Watson statistics indicate similar results as reported in Table 1. The negative value of coefficient for TCL/TA also points out the negative relationship between the aggressiveness of working capital financing policy and return on assets. The higher the TCL/TA ratio, the more aggressive the financing policy, that yields negative return on assets. However, surprisingly, the relationship between Tobin’s q and working capital financing policy has been established as positive and statistically significant. Investors were found giving more weight to the firms which are adopting an aggressive approach towards working capital financing policy and having higher levels of short-term and spontaneous financing on their balance sheets.The control variables used in the regression models are natural log of firm size, sales growth, real GDP growth and the average leverage. All the control variables have their impact on the performance of the firms. Firms’size causes the returns of the firms to be increased and it is found to be statistically significant. Moreover, GROWTH and LVRG are found to be significantly associated with the book-based returns on assets which confirm the notion that leverage and growth are strongly correlated with the book value-based performance measures (Deloof, 2003 and Eljelly,2004). Real GDP growth may not affect the returns based on book values; however, investors may react positively to a positive change in the level of economic activity which is in accordance with the findings of Lamberson (1995).The above results contradict the findings of Gardner et al. (1986), Deloof (2003), Eljelly (2004) and Teruel and Solano (2005); however, they are in accordance with Afza and Nazir (2007) and produced a negative relationship between the aggressiveness of working capital policies and accounting measures of profitability. Managers cannot create value if they adopt an aggressive approach towards working capital investment and working capital financing policy. However, if firms adopt aggressive approach in managing their short-term liabilities, investors give more value to those firms. The degree of aggressiveness of working capital policies adopted helps only in creating shareholders’wealth through increased market performance, whereas accounting performance cannot be increased by being aggressive in managing the working capital requirements. The results of this study are somewhat different from those conducted in the developed economies. Pakistan is one of the emerging economies and Pakistani markets are not fully transparent and efficient to fully absorb the impact of information. The study results confirm this state of Pakistani markets.ConclusionThe present study investigates the relationship between the aggressive/conservative working capital asset management and financing polices and its impact on profitability of 204 Pakistani firms divided into 16 industrial groups by KSE for the period 1998-2005. The impact of aggressive/conservative working capital investment and the financing policies has been examined using panel data regression models between working capital policies and profitability. The study finds a negative relationship between the profitability measures of firms and degree of aggressiveness of working capital investment and financing policies. The firms report negative returns if they follow an aggressive working capital policy. These results were furthervalidated by examining the impact of aggressive working capital policies on market measures of profitability, which was not tested before. The results of Tobin’s q were in line of the accounting measures of profitability and produced almost similar results for working capital investment policy. However, investors were found giving more value to those firms that are more aggressive in managing their current liabilities.The study used a new measure of profitability, i.e., Tobin’s q and panel data regression analysis, to investigate the relationship between working capital management and firm returns in Pakistan. The findings of the present study are expected to contribute significantly to finance literature. The results of the present study are in contradiction to those of some earlier studies on the issue. This phenomenon may be attributed to the inconsistent and volatile economic conditions of Pakistan. The reasons for this contradiction may further be explored in future researches.The study also suggests some policy implications for the managers and prospective investors in the emerging market of Pakistan. Firms with more aggressive policy towards working capital may not be able to generate more profit. So, as far as the book value performance is concerned, managers cannot generate more returns on assets by following aggressive approach towards short-term assets and liabilities. On the other hand, investors are found giving more value to the firms that adopt an aggressive approach towards working capital financing policies. The market value of firms using high level of current liabilities in their financing is more than the book value. The investors believe that firms with less equity and less long-term loans would be able to perform better than the others. However, there are various other factors like agency problem which may play a pivotal role in such cases, and so these factors may further be explored in future.中文译文：激进的营运资本管理政策对企业盈利能力的影响简介企业融资文章历来侧重于研究长期财务决策，特别是投资、资本结构、股利和公司估值决策。

An Analysis of Working Capital Management Resultsacross IndustriesGreg Filbeck and Thomas M. KruegerAbstractFirms are able to reduce financing costs and/or increase the funds available for expansion by minimizing the amount of funds tied up in current assets. We provide insights into the performance of surveyed firms across key components of working capital management by using the CFO magazine’s annual Working Capital Management Survey. We discover that significant differences exist between industries in working capital measures across time. In addition, we discover that these measures for working capital change significantly within industries across time.IntroductionThe importance of efficient working capital management is indisputable. Working capital is the difference between resources in cash or readily convertible into cash (Current Assets) and organizational commitments for which cash will soon be required (Current Liabilities). The objective of working capital management is to maintain the optimum balance of each of the working capital components. Business viability relies on the ability to effectively manage receivables, inventory, and payables. Firms are able to reduce financing costs and/or increase the funds available for expansion by minimizing the amount of funds tied up in current assets. Much managerial effort is expended in bringing non-optimal levels of current assets and liabilities back toward optimal levels. An optimal level would be one in which a balance is achieved between risk and efficiency.A recent example of business attempting to maximize working capital management is the recurrent attention being given to the application of Six Sigma® methodology. Six Sigma® methodologies help companies measure and ensure quality in all areas of the enterprise. When used to identify and rectify discrepancies, inefficiencies and erroneous transactions in the financial supply chain. Six Sigma® reduces Days Sales Outstanding(DSO)，accelerates the payment cycle, improves customer satisfaction and reduces the necessary amount and cost of working capital needs. There appear to be many success stories, including Jennifer Towne’s (2002) report of a 15 percent decrease in days that sales are outstanding, resulting in an increased cash flow of approximately $2 million at Thibodaux Regional Medical Center. Furthermore, bad debts declined from $3.4 million to $600.000. However, Waxer’s (2003) study of multiple firms employing Six Sigma® find s that it is really a “get rich slow” technique with a rate of return hovering in the 1.2 – 4.5 percent range.Even in a business using Six Sigma® methodology, an “optimal” level of working capital management needs to be identified. Industry factors may impact firm credit policy, inventory management and bill-paying activities. Some firms may be better suited to minimize receivables and inventory, while others maximize payables. Another aspect of “optimal” is the extent to which poor financial results can be tied to sub-optimal performance. Fortunately, these issues are testable with data published by CFO magazine, which claims to be the source of “tools and information for the financial executive.” and are the subject of this research.In addition to providing mean and variance values for the working capital measures and the overall metric, two issues will be addressed in this research. One research question is “are firms within a particular industry clustered together at consistent levels of working capi tal measures?” For instance, are firms in one industry able to quickly transfer sales into cash, while firms from another industry tend to have high sales levels for the particular level of inventory. Th e other research question is “D oes working capital management performance for firms within a given industry change from year-to-year?”The following section presents a brief literature review. Next, the research method is described, including some information about the annual Working Capital Management Survey published by CFO magazine. Findings are then presented and conclusions are drawn.Related Literature第2页（共6页）The importance of working capital management is not new to the finance literature. Over twenty years ago, Largay and Stickney (1980) reported that the then-recent bankruptcy of W.T. Grant, a nationwide chain of department stores, should have been anticipated because the corporation had been running a deficit cash flow from operations for eight of the last ten years of its corporate life. As part of a stu dy of the Fortune 500’s financial management practices, Gilbert and Reichert (1995) find that accounts receivable management models are used in 59 percent of these firms to improve working capital projects, while inventory management models were used in 60 percent of the companies. More recently, Farragher, Kleiman and Sahu (1999) find that 55 percent of firms in the S&P Industrial index complete some form of a cash flow assessment, but did not present insights regarding accounts receivable and inventory management, or the variations of any current asset accounts or liability accounts across industries. Thus, mixed evidence exists concerning the use of working capital management techniques.Theoretical determination of optimal trade credit limits are the subject of many articles over the years (e.g. Schwartz 1974; Scherr 1996) with scant attention paid to actual accounts receivable management. Across a limited sample, Weinraub and Visscher (1998) observe a tendency of firms with low levels of current ratios to also have low levels of current liabilities. Simultaneously investigating accounts receivable and payable issues. Hill·Sartoris and Ferguson (1984) find differences in the way payment dates are defined. Payees define the date of payment as the date payment is received, while payors view payment as the postmark date. Additional WCM insight across firms, industries and time can add to this body of research.Maness and Zietlow (2002. 51. 496) presents two models of value creation that incorporate effective short-term financial management activities. However, these models are generic models and do not consider unique firm or industry influences. Maness and Zietlow discuss industry influences in a short paragraph that includes the observation that “An industry a company is located in may have more influence on that company’s fortunes than ov erall GNP” (2002. 507). In fact, a careful review of this 627-page textbook finds only sporadic information on actual firm levels of WCM dimensions, virtually nothing on第3页（共6页）industry factors except for some boxed items with titles such as “Should a Retailer Offer an In-House Credit Card” (128) and nothing on WCM stability over time. This researchwill attempt to fill this void by investigating patterns related to working capital measures within industries and illustrate differences between industries across time.An extensive survey of library and Internet resources provided very few recent reports about working capital management. The most relevant set of articles was Weisel and Bradley’s (2003) article on cash flow management and one of inventory control as a result of effective supply chain management by Hadley (2004).Research MethodThe first annual CFO Working Capital Survey, a joint project with REL Consultancy Group, was published in the June 1997 issue of CFO (Mintz and Lezere 1997). REL is a London, England-based management consulting firm specializing in working capital issues for its global list of clients. The original survey reports several working capital benchmarks for public companies using data for 1996. Each company is ranked against its peers and also against the entire field of 1000 companies. REL continues to update the original information on an annual basis.REL uses the “cash flow from operations” value l ocated on firm cash flow statements to estimate cash conversion efficiency (CCE). This value indicates how well a company transforms revenues into cash flow. A “days of working capital” (DWC) value is based on the dollar amount in each of the aggregate, equally-weighted receivables, inventory and payables accounts. T he “days of working capital” (D WC) represents the time period between purchases of inventory on account from vendor until the sale to the customer, the collection of the receivables and payment receipt. Thus, it reflects the company’s ability to finance its core operations with vendor credit. A detailed investigation of WCM is possible because CFO also provides firm and industry values for days sales outstanding (A/R), inventory turnover and days payables outstanding (A/P).Research Findings：Average and Annual Working Capital Management Performance Working capital management component definitions and average values for the entire 1996 – 2000 period. Across the nearly 1.000 firms in the survey, cash flow from operations,第4页（共6页）defined as cash flow from operations divided by sales and referred to as “ca sh conversion efficiency” (CCE). Averages 9.0 percent. Incorporating a 95 percent confidence interval, CCE ranges from 5.6 percent to 12.4 percent. The day’s working capital (DWC), defined as the sum of receivables and inventories less payables divided by daily sales, averages 51.8 days and is very similar to the days that sales are outstanding (50.6). Because the inventory turnover rate (once every 32.0 days) is similar to the number of days that payables are outstanding (32.4 days). In all instances, the standard deviation is relatively small, suggesting that these working capital management variables are consistent across CFO reports.Industry Rankings on Overall Working Capital Management Performance CFO magazine provides an overall working capital ranking for firms in its survey, using the following equation: Industry-based differences in overall working capital management are presented for the twenty-six industries that had at least eight companies included in the rankings each year. In the typical year, CFO magazine ranks 970 companies during this period. Industries are listed in order of the mean overall CFO ranking of working capital performance. Since the best average ranking possible for an eight-company industry is 4.5 (this assumes that the eight companies are ranked one through eight for the entire survey). It is quite obvious that all firms in the petroleum industry must have been receiving very high overall working capital management rankings. In fact, the petroleum industry is ranked first in CCE and third in DWC (as illustrated in Table 5 and discussed later in this paper). Furthermore, the petroleum industry had the lowest standard deviation of working capital rankings and range of working capital rankings. The only other industry with a mean overall ranking less than 100 was the Electric & Gas Utility industry, which ranked second in CCE and fourth in DWC. The two industries with the worst working capital rankings were Textiles and Apparel. Textiles rank twenty-second in CCE and twenty-sixth in DWC. The apparel industry ranks twenty-third and twenty-fourth in the two working capital measuresConclusions第5页（共6页）The research presented here is based on the annual ratings of working capital management published in CFO magazine. Our findings indicate a consistency in how industries “stack up” against each other over time with respect to the working capita l measures. However, the working capital measures themselves are not static (i.e. averages of working capital measures across all firms change annually); our results indicate significant movements across our entire sample over time. Our findings are important because they provide insight to working capital performance across time and on working capital management across industries. These changes may be in explained in part by macroeconomic factors. Changes in interest rates, rate of innovation and competition are likely to impact working capital management. As interest rates rise, there would be less desire to make payments early, which would stretch accounts payable, accounts receivable and cash accounts.The ramifications of this study include the finding of distinct levels of WCM measures for different industries, which tend to be stable over time. Many factors help to explain this discovery. The improving economy during the period of the study may have resulted in improved turnover in some industries, while slowing turnover may have been a signal of troubles ahead. Our results should be interpreted cautiously. Our study takes places over a short time frame during a generally improving market. In addition, the survey suffers from survivorship bias – only the top firms within each industry are ranked each year and the composition of those firms within the industry can change annually.Further research may take one of two lines. First, there could be a study of whether stock prices respond to CFO magazine’s publication of working cap ital management ratings. Second, there could be a study of which, if any, of the working capital management components relate to share price performance. Given our results, these studies need to take industry membership into consideration when estimating stock price reaction to working capital management performance.第6页（共6页）。
