关键词：并购动机；风险分析；风险防范；会计方法引言近年来，受国际金融危机快速蔓延和世界经济增长明显减速的影响，加上目前我国经济尚未解决的深层次矛盾和问题，我国经济生活中运行中的困难增加，经济下行压力加大，企业经营困难增多。
在此背景下，我国经济面临着前所未有的挑战和机遇，行业调整、企业洗牌在全球范围内展开，中国企业并购活动日趋活跃。
事实上自1998年以来，全球企业并购就开始出现新动向，它是国际政治、经济局势变化的反映，也是全球一体化程度加深、国际竞争力加剧、技术进步加决的结果。
企业并购对经济运行有着深刻的影响。
因此人们想了解，企业并购的动因是什么？各个时期的动因相同吗？企业并购会面临什么样的风险？人们该如何防范?企业并购的会计方法又是如何选择的？一企业并购的动机因企业并购动因不尽相同。
1997年，吴永林在《企业并购动因和目的析论》中从宏观和微观两个角度分析了企业并购的动机和原因。
宏观来看：（一）企业并购是我国产业重组的需要（二）企业并购是我国经济增长的需要（三）企业并购是我国市场组织的需要（四）企业并购是我国科技进步的需要。
微观上看，企业并购也有其内在的动机因素导致企业的并购冲动：（一）壮大企业（二）获得技术（三）强化竞争（四）优势互补。

企业通过并购可以实现资源的互补性，提高生产效率和市场份额，进而获得更高的利润和回报。
2.战略目标理论战略目标理论认为，企业并购的动因主要源于企业战略目标的实现需要。
企业在制定并购策略时，通常会考虑到自身现有资源能力与目标市场的差距，通过并购可以快速获取所需的资源和能力，并加快实现战略目标的进程。
企业并购的战略目标包括国际化、多元化、垂直一体化等。
3.经验学习理论经验学习理论认为，企业并购行为受到企业经验积累的影响。
企业通过一系列并购行为，积累了丰富的经验和知识，从而能够更好地应对并购决策所面临的不确定性和风险。
企业在并购决策中会参考过去的并购经验，评估风险和机会，并选择最合适的并购战略和实施方式。
4.交易成本理论交易成本理论认为，企业进行并购的动因主要是为了降低交易成本。
交易成本包括信息获取成本、谈判成本、合同监管成本、交易执行成本等。
通过并购可以消除市场不完全性和信息不对称性，降低交易成本，提高资源配置效率和经济效益。
5.市场势力理论市场势力理论认为，企业进行并购行为主要受到市场势力的影响。

企业并购文献综述及外文文献资料
本文档包括改专题的：外文文献、文献综述一、外文文献Financial synergy in mergers and acquisitions. Evidence from Saudi ArabiaAbstractBusinesses today consider mergers and acquisitions to be a new strategy for their company's growth. Companies aim to grow through increasing sales, purchasing assets, accumulating profits and gaining market share. Thus; the best way to achieve any of the above-mentioned targets is by getting into either a merger or an acquisition. As a matter of fact, growth through mergers and acquisitions has been a critical part of the success of many companies operating in the new economy. Mergers and acquisitions are an important factor in building up market capitalization. Based on three structured interviews with major Saudi Arabian banks it has been found that mergers motivated by economies of scale should be approached cautiously. Similarly, companies should also approach vertical mergers cautiously as it is often difficult to gain synergy through a vertical merger. Firms should seek out mergers that allow them to acquire specialized knowledge. It has also been found that firms should look for mergers that increase market power whilst avoiding unrelated mergers or conglomerate mergers.Keywords: Synergy, Mergers and Acquisitions, Saudi Arabia 1. IntroductionThere is a major difference between mergers and acquisitions. Mergers occur between similarly sized companies and the collaboration is "friendly" between both companies. However, Acquisitions often occur between differently sized companies and the partnership is usually forced and hostile.Wheelen and Hunger (2009) define a merger as a transaction involving two or more corporations in which stock is exchanged but in which only one corporation survives. In other words, the two companies become one and the name for the corporation becomes composite and is derived from the two original names. Furthermore, an acquisition is the purchase of a company that is completely absorbed as an operating subsidiary or divisionof the acquiring corporation (Wheelen and Hunger, 2009). The authors also state thathostile acquisitions are called takeovers.The main reason for firms entering into mergers and acquisitions (M&A) is to grow, andcompanies grow to survive (Akinbuli, 201 2). Growth strategies expand the company's activities and add to its value since larger firm have more bargaining power than smaller ones. A firm sustaining growth will always have more opportunities for advancement, promotions and more jobs to offer people (Wheelen and Hunger, 2009). In general, mergers and different types of acquisitions are performed in the hope of realizing an economic gain. For such a business deal to take place, the two firms involved must be worth more together than each was apart.A few of the prospective advantages of M&A include achieving economies of scale, combining complementary resources, garnering tax advantages, and eliminating inefficiencies. Other reasons for considering growth through acquisitions contain obtaining proprietary rights to products or services, increasing market power by purchasing competitors, shoring up weaknesses in key business areas, penetrating new geographic regions, or providing managers with new opportunities for career growth and advancement (Brown, 2005).Many firms choose M&A as a tool to expand into a new market or new area of expertise since it is quicker and cheaper than taking the risk alone. Furthermore, M&A happen when senior executives feel enthusiastic and excited about a potential deal ; the idea of successfully pursuing and taking over another company before the company s competitors are able to do so. Competition in a growing industry drives firms to acquire others. In fact, a successful merger between companies increases benefits for the entire corporation.However, failures also occur in M&A as indicated by Haberbserg and Rieple (2001) and Akinbuli (2012). They showed that 50% of acquisitions are unsuccessful; they increase market power but do not necessarily increase profits. Brown (2005) explains the reasons for the high failure rate of M&A as follows:(a)Over-optimistic assessment of economies of scale. Economies of scale are usually achieved at certain business size. However, expansion beyond the optimum level results in disproportionate cost disadvantages that lead to various diseconomies of scale.(b)Inadequate preliminary investigation combined with an inability to implement the amalgamation efficiently. Resistance to change and the inability for the acquired company to manage change well is a main reason for failure due to the resistance of the employees and management of both companies involved.(c)Insufficient appreciation of the personnel problems, which will arise, is due mainly to the differing organizational cultures in each company.(d)Dominance of subjective factors such as the status of the respective boards of directors.Therefore, drafting careful plans before and after the merger is a necessity that should not be overlooked. Some companies find the solution in hiring a change manager who will add value and better manage the transition of the "marriage between both companies" (Brown, 2005).2.Synergy in M&A and financial synergyThis section discusses the literature review in order to identify the importance of acquiring financial synergy in the M&A.2.1Synergy in M&ASynergy, as defined in the business dictionary, is the state in which two or more agents, entities, factors, processes, substances, or systems work together in a particularly fruitful way that produces an effect greater than the sum of their individual effects. Synergy is the magic force that allows for enhanced cost efficiencies of the new business. Synergy takes the form of revenue enhancement and cost savings (Mergers and acquisitions: Definition, n.d.).Synergy is also expressed as an increase in the value of assets as a result of their combination. Expected synergy is the justification behind most business mergers. For example, the 2002 combination of Hewlett-Packard and Compaq was designed to reduce expenses and capitalize on combining Hewlett-Packard's reputation for quality with Compaq's impressive distribution system (Synergy Business Definition, n.d.).Through research it has been noted that synergy is the concept that two businesses will generate greater profits together than they could separately (Wheelen and Hunger, 2009). Synergy is said to exist for a divisional corporation if the return on investment of each division is greater than what the return would be if each division were an independent business (Wheelen and Hunger, 2009). In order to succeed cooperation between the partners is the basic ingredient for achieving growth through synergy (Rahatullah, 201 0). This requires partners to build trust, commitment, and secure consensus, to achieve their targets (Gronroos, 1997; Ring and Van-de-Ven, 1994).Synergy can take several forms. According to Goold and Campbell (1 998) synergy is demonstrated in six ways: benefiting from knowledge or skills, coordinated strategies,shared tangible resources, economies of scale, gaining bargaining power over suppliers and creating new products or services.M8<A result in the creation of synergies, the sharing of manufacturing facilities, software systems and distribution processes. This type of synergy is referred to as operational synergy and is seen mostly in manufacturing industries. Another motive for forming an acquisition is gaining greater financial strength by purchasing a competitor, which increases market share. The aim of mergers and acquisitions is to achieve improvement for both companies and produce efficiency in most of the company's operations. (Haberberg and Rieple, 2001).However, Brown (2005) summarizes the sources of synergy that result from M8<A underthe following headlines:1.Operating economies which include:(a)Economies of scale: Horizontal mergers (acquisition of a company in a similarline of business) are often claimed to reduce costs and therefore increase profits due to economies of scale. These can occur in the production, marketing or finance divisions.Note that these gains are not expected automatically and diseconomies of scale may also be experienced. These benefits are sometimes also claimed for conglomerate mergers(acquisition of companies in unrelated areas of business) in financial and marketingcosts.(b)Economies of vertical integration: Some acquisitions involve buying out other companies in the same production chain. For example, a manufacturer buys out a rawmaterial supplier or a retailer. This can increase profits through eliminating the middleman in the supply chain.(c)Complementary resources: It is sometimes argued that by combining the strengths of two companies a synergistic result can be obtained. For example, combining a company specializing in research and development with a company strong in the marketing area could lead to gains. Combining the expertise of both firms would benefit each company through the gained knowledge and skills that individually they lack.(d)Elimination of inefficiency: If either of the two companies had been badly managed; its performance and hence its value can be improved by the elimination of inefficiencies through M&A, Improvements could be obtained in the areas of production, marketing and finance.2.Market power; Horizontal mergers may enable the firm to obtain a degree of monopoly power which could increase its profitability. Coordinated strategies between both companies will lead the entire organization in gaining competitive advantage. Gaining bargaining power over suppliers is realized since the company is larger in size after the merger.3.Financial gains; Companies with large amounts of surplus cash may see the acquisition of other companies as the best application for these funds. Shared tangible resources such as sharing a bigger building, more office supplies, equipment, manufacturing facilities and research and design labs will also lead to a reduction in costs translated into better financial performance. McNeil (2012) identifies that the shareholders of a business under M&A process may benefit from the sale of their stocks, this is especially true if the M&A is with a better, bigger and more reputable prospective partner.4.Others; such as surplus management talent, meaning that companies with highly skilled managers can make use of their qualified personnel only if they have problems to solve. The acquisition of inefficient companies allows for maximum utilization of skilled managers. Incorporating the efforts of both management teams will drive the creation of innovative products or services.The synergy factor prevails in the M&A when the firms produce a greater return than the two individual firms owing to reasons such as improvements in efficiency and an increase in market power for the merged or acquired firms (Berkovitch and Narayana, 1993).2.2Financial synergyAs defined by Knoll (2008), financial synergies are performance advantages gained by controlling financial resources across businesses of firms. There exist four types of financial synergies, which are:1.Reduction of corporate risk: Reduction of corporate risk is increasing the risk capacity of the overall firm, which means the ability of the firm to bear more risk. Meaning that by increasing the risk capacity the shareholders will invest more in the company and the firm will gain benefits such as coinsurance effects.2.Establishment of internal capital market: Establishing internal capital gains means that the firm will decrease its financing costs and will increase financialflexibility which results in the company having higher liquidity and the ability to payits creditors easily.3.Tax advantages: Tax advantages by reducing the tax liabilities of the firm using the losses in one business to offset profits in the other business referred to as "profit accounting".4.Financial economies of scale: Financial economies of scale reducing transaction cost in issuing debt and equity securities (Knoll, 2008).3.Methodology and resultsFor this project, the method of interviews was used due to it being the most appropriate way to gather information about the interpretation of events, as to why some mergers produce synergy while others do not; and to understand the reasons why companies enter into mergers. In Saudi Arabia it is difficult to secure responses from senior executives. Approaching such a person is not only difficult protocol wise but there are bureaucratic hurdles. The quantitative analysis is more suitable for large scale data collection (Denzin and Lincoln, 1997). Whereas, qualitative research provides the researcher with the perspective of target audience members through captivation and direct interaction with the people under study (Glesne and Peshkin, 1992). These methods help to comprehend what others perceive of a certain phenomenon, postulates Creswell (1994).The planned interview method was to use a structured interview. In a structured interview, the researcher knows in advance what information is needed and asks a predetermined set of questions (Sekaran and Bougie, 2009). The same questions are asked of all interviewees, which allows for better comparison of the responses than unstructured interviews, where the interviewees are asked different questions. The structured interview process does allow the researcher to ask different follow up or probing questions based on the interviewee's response. This allows the interviewer to identify new factors and gain a deeper understanding of the topic (Sekaran and Bougie, 2009).Since the interviewees were located in different parts of Saudi Arabia the interviews were scheduled in advance and conducted face to face. The data was gathered by taking notes during the interviews, which were not recorded as that may have seemed too intrusive.When conducting interviews it is important to conduct them in a manner that is free of bias or inaccuracies. According to Sekaran and Bougie (2009), bias can be introduced by theinterviewer, interviewee or the situation. Interviewers can introduce bias by distorting the information that they hear so it aligns with their expected responses to the question or through simple misunderstandings. To prevent this, the respondents' answers were summarized back to them before moving on to the next question. Interviewees can introduce bias if they do not like the interviewer or if they phrase the answers to be biased towards what they think the interviewer wants to hear. Since the interviewees were obtained through referrals, it is highly unlikely that they gave false responses. Also, the basic area of research was discussed with the interviewees, but no hypothesis was advance to them, such that they would skew their answers to what they though the interviewer wanted to hear.Three companies were interviewed and asked a specific set of questions (see Appendix). There are numerous reasons to interview three companies in Saudi Arabia. These are the following:*The M&A in Saudi Arabia are normally carried out by large size companies.*It is difficult to reach out to the senior managers to discuss such issues.*The officers are also tied by company confidentiality rules to not divulge information.*The number of M&A is also significantly less in comparison with other countries.*The researchers, using diverse resources including personal contacts and formal requests, were able to reach out to three of the major companies of the Kingdom.An interview was conducted with National Commercial Bank (NCB) NCB is an international bank headquartered in Saudi Arabia and engaged in personal, business and private banking, and wealth management (NCB, 2011 ). Another interview was done with Samba Financial Group. Samba is also an international bank headquartered in Saudi Arabia that is engaged in personal and business banking (Samba, 2011). The third company that was interviewed was Savola Holding Company, which is headquartered in Jeddah, Saudi Arabia and is engaged in the food industry. Through subsidiary companies, Savola is engaged in the manufacturing of vegetable oils, dairy products and food retailing operations both in Saudi Arabia and other international markets. Due to strict confidentiality of the companies interviewed, the names of the people will not be mentioned or their titles. This was the most important condition in order to conduct these interviews.Each of the three companies has been involved in significant mergers. NCB's most significant merger was when it acquired a Turkish bank, Turkiye Finans Katilm Bank in 2008.Samba's most significant merger was its acquisition of Cairo Bank in 1 999. Savola's most significant acquisition was its acquisition of Al-Marai in 1 991.NCB has engaged in four mergers overall and three international mergers. In addition to its acquisition of the Turkish bank, it acquired Estate Capital Holdings, The Capital Partnership Group Limited and NCB Capital. The acquisition oftheTurkish bank was considered its most successful acquisition because it allowed NCB to expand into a new international market with strong growth.While NCB does not consider any of its acquisitions to be a failure, it has recognized losses through goodwill impairment, even in the Turkish bank acquisition. Samba's most prominent M8<A has been with Cairo bank of Egypt.Savola has engaged in about 10 mergers including a few international mergers. It considers its acquisition of Panda (a supermarket chain) in 1998 to be its most successful because it allowed Savola to gain a major presence in the food retailing market and increases revenues significantly. Savola has had a couple of mergers that it considered to be failures. One such example was when it acquired a real estate company in Jordan. This company was outside Savola's core business and outside its home country. Savola's learning from this failure was not to invest outside its core business in a foreign country as there was no ability to create any value through this merger and it was investing in a country that it did not know as well as its home country. Another failed merger occurred when it acquired an edible oil company in Kazakhstan. This merger failed because even though the acquired company had good fundamentals, the value creation mechanisms were quite different between the two companies.Strategic motivations for mergers were discussed with the companies and Samba provided details. One motivation is to increase lines of business. Another motivation is to move into a new geographic area. In many cases when expanding into a new country, it is easier to acquire an existing business than try to start a new one. Another motivation is to increase market share.Particularly in a mature industry, a company can gain market share quickly through an acquisition, while it is usually a slow process to gain market share organically in an incremental manner.All the companies tried to achieve company growth and synergy in their mergers.The criteria and selection process for mergers were also discussed with the companies. Savola worked with financial institutions to identify acquisition target companies. Savola looked for companies that were among the leaders in their respective markets. Savola believed that companies that were leaders generally had good processes and were well managed, so their operations would be good to acquire. After the failed merger with the real estate company, Savola looked to acquire companies related to its core food manufacturing and sales business. All companies obviously reviewed financial statements closely to assess the financial condition of the acquired firm. Samba noted that sometimes in the banking and financial industry, strong banks will acquire banks that are in a weak financial condition in a rescue operation, often due to political reasons. In reviewing candidates for a merger, Savola engages its operations and technical team to assess the target company's operation, processes and potential fit into the business group.The three interviewed companies use various metrics to evaluate the success of the merger. Savola evaluates the revenue growth of the sector where the acquisition occurred along with the market share and operating cost. The goals are to increase revenue,increase market share or reduce operating cost. Samba evaluated similar metrics of market share and operating cost.Samba noted that it usually takes until the second year after a merger to evaluateits success. In the first year, there are onetime costs associated with integration costs of the merger. It usually takes until the second year to see reduced operating costs from activities such as closing and consolidating branches.The different ways to obtain synergy in a merger were discussed with the companies. Savola looked to obtain synergy through economies of scale, as acquisitions would add to the company's shipment volume, which would allow the company to reduce freight and distribution costs. Samba also looked to obtain synergy through economies of scale and eliminating the duplication of activities. When it acquired Cairo bank, which had previously acquired United Saudi Commercial Bank, Samba was able to cut costs in Saudi Arabia by reducing the number of bank branches and ATMs. NCB was able to gain financial synergies in its mergers by developing a more diversified and lower risk portfolio ofinvestments.From the responses to the questions included in the structured interview, thefollowing findings can be highlighted:A.Mergers to Expand to International Markets:One finding is that firms undertake some mergers to expand into new international markets. In doing so they are gaining the synergy of the acquired firm's knowledge of the market. In these cases, the acquiring firm saves the costs of starting up a business in the new country, gaining the necessary approvals, learning how to do business successfully in the market and building a brand in the country. This is especially true in the bank and finance industry, where the industry is closely regulated. It can be easier to acquire a company that already has all of the necessary regulatory approvals as opposed to trying to gain all of the necessary approvals to conduct business legally in the selected market. Also, building a brand is important in the banking industry, as consumers and commercial customers prefer to do business with a trusted firm. In these mergers, synergy can be gained through the acquired firm's knowledge of the market and the acquiring firm's capital. The new infusion of capital can often allow the acquired firm to grow in the market. The NCB acquisition of the Turkish bank is a good example of this type of synergy.Even when a firm acquires a company within their own market there is the chance to create synergies through knowledge gained and transferred. In many cases, the acquired firm has certain processes in some areas that are better than the acquiring firm, so selecting the best process allows the merged firm to improve its overall processes. Also, the acquiring company usually has some processes that are better than the acquired firm's processes in some areas, which allows the company to improve the newly acquired operations. As noted by Samba in its interview, the goal is to utilize the optimum processes from both companies to produce synergy from the merger.B.Mergers to Gain Economies of Scale:Firms also seek and gain synergies through economies of scale. Larger businesses can often gain economies in certain business activities including manufacturing, distribution and sales. One of the goals of Samba's mergers was to gain synergies through economies of scale. In their mergers, Savola hoped to gain economies of scale in shipping and distribution activities. Economies of scale can also be achieved in the banking industry since the cost of processing checks or issuing credit cards is likely to decline on a per unit basis with increasing volume; therefore the fixed cost associated with these activities can be spread over a larger volume. The result is reduced costs, which makes the merged firm more profitable and more competitive in the market.C.Eliminating Inefficiencies:Another way to achieve synergy is through elimination of inefficiencies. Removing the duplication of resources can eliminate inefficiencies. In horizontal mergers, it is common for the merged company to consolidate operations, close offices and reduce staff. Samba mentioned that reducing the number of bank branches, ATMs and staff was one of the ways that they drove cost efficiencies after acquiring Cairo Bank. Samba also provided the insight that there is a delay for these cost efficiencies to show up in financial performance, since it takes time to remove the duplication of resources involved and there are one-time costs associated with removing the duplication of resources. The official also pointed out that the success or failure of a merger should not be evaluated until at least two years after the merger.D.Gain More Market Power:Firms also try to achieve synergies through an increase in market power, by controlling a larger share of the market. Discussions with all respondents implied increasing market share to be one of the motivations to enter into a merger. Savola and Samba both mentioned increasing market share as a way to judge the success of a merger. Greater market power can improve profitability through a couple of mechanisms. One such mechanism is greater monopoly pricing power in the market, which allows firms to increase prices due to reduced competition. This is one reason that major mergers have to be approved by government regulators who s objective is to maintain a competitive market. A second mechanism is increased buyer power over suppliers. Since the merged firm represents a greater portion of an industry's business, suppliers to the industry want the merged firm's business more, which gives the merged firm better negotiating power over suppliers. This allows the merged firm to reduce its costs and increase it profits. However, a strategic perspective could be on the supplier side as Porter (1 998) identifies that the stronger the company becomes the weaker the supplier becomes thus reducing their bargaining power.E.Gain Growth:Growth is one of the main reasons that firms undertake mergers, as this was mentioned by all of the companies interviewed. Companies seek growth through mergers because it can allow them to gain market power, which generally leads to increased profits. Mergers are also a way to satisfy investors'/shareholders' expectations for growth. In many cases, itis difficult to grow a business in a mature market organically, so mergers are often the best way to achieve growth.Samba provided a perspective on the use of acquisitions as a growth strategy. Samba believed that within the same industry organic growth was less expensive than growth through acquisition because a premium had to be paid for another company's operations in the same industry. Samba believed that when trying to expand into a different industry, growth through acquisition was less expensive than organic growth because the firm had no knowledge or expertise in the new industry. Samba used this philosophy when formulating their strategic growth plans. If the company simply wanted to expand within their current industry, the focus would be on organic growth initiatives, whereas if the company wanted to grow by expanding into new industries, the focus would be on acquisitions.F.Reducing RisksFirms can gain synergies by reducing their overall risk through diversification and reducing their cost of capital. Generally, this is a weak form of synergy and prone to failures because it often entails firms moving into businesses outside of their core competencies. The businesses are then run without the knowledge of how to run a business successfully in that market. This leads to operational losses or subpar performance in the industry, which negates any synergistic gains from reducing the company's overall risk.This was experienced by Savola, who acquired a real estate company, which was outside its core business of the food market. Consequently, the acquired real estate business produced subpar performance and losses, which negated any gains from reducing risk. Thus, the merger was considered to be a failure because it reduced the overall value of the firm. Due to the difficulties of creating financial synergies through diversification, there are few conglomerate mergers and few conglomerate companies.The companies interviewed look for synergies when considering mergers and try to estimate the potential synergistic gains that could be attained in a proposed merger. The potential synergies gained depend on the industry and the characteristics of the company acquired. In the failed mergers, the firm overestimated the amount of synergy that could be gained through the merger. Savola overestimated the synergy that could be gained through the acquisition of a real estate company because the only synergy that could be gained was。

企业并购动因文献综述1.国外相关研究文献。
兼并与收购是资本市场永恒的主题，从19 世纪末至今，西方国家已经历了六次并购浪潮。
企业并购动因是促成并购行为的发端，可以解释为诱发企业并购行为的因素。
国外学者对于企业并购动因作了广泛而深入的研究，提出了多种并购动因理论。
一是协同效应理论。
Ansoff ( 1965 )最早提出协同效应理论，即指并购双方资产、能力等方面的互补或协同从而提高公司业绩和创造价值，使合并后公司的整体业绩大于合并前各自原有业绩的总和。
Berkovitch和Narayana(1993)也将企业并购动因归结为协同效应或效率，并分析该动因对合并后企业收益的影响。
Sirower ( 1997) 认为如果并购后的业绩改进已经被市场预期，那么该预期将以并购溢价的形式体现出来，并归集到目标公司股东手中。
Hagcdoom、Duysters(2000)在对计算机行业的并购研究中证明，在经营战略和组织结构上相近的两个公司合并有利于发挥双方技术协同效应，促进技术资源的重新配置。
协同效应理论包括经营协同效应、财务协同效应以及管理协同效应。
经营协同效应假定存在着规模经济，合并后可以对企业规模进行扩充和调整，达到最佳规模经济，使相关业务单元的成本降低。
Stigler(1950)认为公司间的并购可以减少竞争者，扩大优势企业的规模，增加对市场的控制能力，从而导致市场垄断。
即使不能形成垄断，也可以由于并购扩大的规模效应构成潜在进入者的市场进入壁垒。
Meeks(1997)将并购的动因归结为扩大规模、提高市场份额和对市场的控制能力。
财务协同效应是指企业控股权的更迭会给企业带来财务方面的效益，这种效益的取得是由于税法、会计处理和证券交易而产生的。
此外，合并后企业将外部融资转化为内部融资，融资风险与成本下降。
Hannah和Kay(1977)认为税收制度有时会鼓励企业参与并购，其一是营业亏损和税收抵免的延续，通过将利润向亏损企业转移，实现合法避税。

企业并购绩效及影响因素文献综述一、引言企业并购是指两个或多个公司之间通过收购或合并等方式，以实现规模经济、资源整合和市场扩展为目的的一种商业活动。
在全球化和市场竞争日益激烈的今天，企业并购已成为企业发展战略中不可或缺的一部分。
并购活动并非总能带来预期的效果。
很多并购案例以失败告终，给相关公司和投资者带来了严重的损失。
研究企业并购绩效及其影响因素对于理解并购活动的成功与否，具有重要的理论和实践意义。
本文将综述国内外学者对企业并购绩效及其影响因素的研究成果，以期为相关领域的学术研究和实际操作提供参考。
二、企业并购绩效评价企业并购的绩效评价是一个复杂的课题，绩效评价的结果将直接影响并购的成败。
在学术研究和实际操作中，对企业并购绩效的评价多从财务绩效和战略绩效两个方面展开。
1. 财务绩效评价企业并购后的财务绩效是最直观的表现，也是衡量企业并购成败的重要指标之一。
而对企业并购的财务绩效评价主要体现在企业的收益能力、资本结构、市场价值和现金流量等方面。
对于并购后企业的收益能力，通常通过销售收入、净利润、息税前利润（EBIT）等指标来反映。
而资本结构方面，则主要关注企业的财务杠杆、偿债能力和股权结构等情况。
市场价值和现金流量也是企业并购绩效评价的重要方面。
2. 战略绩效评价企业并购的战略绩效主要关注企业战略目标的实现情况，包括市场份额的扩大、产品创新、技术升级和品牌价值等方面。
通过对市场份额、市场渗透率、产品销售情况和品牌影响力等指标的分析可以评估企业并购后的战略绩效情况。
三、影响企业并购绩效的因素企业并购绩效的成败受多种因素的影响，其中包括公司内部因素、外部市场因素和并购过程中的管理决策因素等。
1. 公司内部因素公司内部因素包括企业规模、企业业绩、企业文化、管理制度和团队合作等。
研究表明，企业规模较大、业绩稳定、管理制度健全、企业文化相近、团队协作良好的企业，进行并购后的绩效往往更好。
2. 外部市场因素外部市场因素主要包括宏观经济环境、行业竞争环境、市场需求和法规政策等方面。

并购阶段概况的文献综述
并购阶段概况的文献综述并购（Mergers and Acquisitions）是指一家公司通过收购另一家公司的股权或资产，或者与另一家公司合并来实现业务战略目标的行为。
并购活动的频繁发生使其成为了现代商业中的重要现象。
本文将对并购阶段概况进行文献综述，以探讨并购活动在不同阶段的特点和影响。
一、并购活动的阶段1. 策略规划阶段并购活动通常始于公司的战略规划阶段。
在这个阶段，公司会通过分析市场和竞争环境、评估自身资源和优势，并制定相应的发展战略。
公司会考虑自身的业务领域、市场定位和未来发展方向，从而确定是否需要通过并购来实现战略目标。
2. 目标筛选阶段一旦公司决定通过并购来实现战略目标，下一步就是确定适当的并购目标。
在这个阶段，公司会对潜在的目标公司进行充分的调研和分析，包括财务状况、商业模式、市场地位和管理团队等方面的情况。
公司还会考虑目标公司与自身的业务互补性和整合难度，从而筛选出最适合的并购目标。
3. 谈判阶段一旦确定了并购目标，公司就会开始与目标公司展开谈判。
在谈判阶段，公司需要就价格、交易结构、股权转让和员工待遇等方面与目标公司进行协商。
公司还需要与监管部门和股东进行沟通，确保交易的合规性和顺利性。
4. 尽职调查阶段一旦双方达成初步协议，就需要进行尽职调查。
在这个阶段，公司会对目标公司的全部资产、负债、法律事务和商业情况进行全面的调查和审核。
通过尽职调查，公司可以更全面地了解目标公司的实际情况，规避潜在的风险和问题。
5. 合同签署阶段在完成尽职调查之后，双方可以签署正式的并购协议。
并购协议通常包括交易价格、交易结构、股权转让和员工待遇等方面的内容。
通过签署并购协议，交易正式落实，双方开始筹备后续的交易流程。
6. 政府批准阶段在协议签署之后，公司需要向相关监管部门提交并购申请，并等待政府的批准。
在一些情况下，特别是涉及行业垄断和国家安全的并购案例中，政府可能会对并购进行调查和评估，以确保交易不会对市场和国家利益产生不利影响。

关于企业并购的文献综述
摘要
企业并购已经成为世界范围内一种普遍的现象。
为了更加深入了解企业并购的方方面面，本文尝试对该领域内主要贡献者的观点进行整理、归纳，并梳理其理论逻辑，帮助广大理论和实践工作者不断地去发掘和完善。
本文对文献的综述包括以下三个方面：一、企业并购的动因。
二、企业并购的风险分析。
三、企业并购的会计方法的选择。
本文以对我国企业并购的动机和原因展开，企业并购的动因是多种多样的，各个文献视角不同，但都包括了企业内部因素和社会环境因素。
第二部分分析企业并购面临的风险，各文献从不同角度分析企业并购的风险并试图提出一些防范风险的建议。
第三部分围绕企业并购会计方法的选择展开。
关键词：并购动机；风险分析；风险防范；会计方法
引言
近年来，受国际金融危机快速蔓延和世界经济增长明显减速的影响，加上目前我国经济尚未解决的深层次矛盾和问题，我国经济生活中运行中的困难增加，经济下行压力加大，企业经营困难增多。
在此背景下，我国经济面临着前所未有的挑战和机遇，行业调整、企业洗牌在全球范围内展开，中国企业并购活动日趋活跃。
事实上自1998年以来，全球企业并购就开始出现新动向，它是国际政治、经济局势变化的反映，也是全球一体化程度加深、国际竞争力加剧、技术进步加决的结果。
企业并购对经济运行有着深刻的影响。
因此人们想了解，企业并购的动因是什么？各个时期的动因相同吗？企业并购会面临什么样的风险？人们该如何防范?企业并购的会计方法又是如何选择的？
一企业并购的动机因
企业并购动因不尽相同。
1997年，吴永林在《企业并购动因和目的析论》中从宏观和微观两个角度分析了企业并购的动机和原因。
宏观来看：（一）企业并购是我国产业重组的需要（二）企业并购是我国经济增长的需要（三）企业并购是我国市场组织的需要（四）企业并购是我国科技进步的需要。
微观上看，企业并购也有其内在的动机因素导致企业的并购冲动：（一）壮大企业（二）获得技术（三）强化竞争（四）优势互补。
如何搞好国有大中型企业是我国经济体制改革进一步深化的关键，根据“抓大放小”的方针全面实施大公司大集团发展战略，
促使理论工作者开始探讨企业并购这一产权交易高级形式的作用和做法而企业也正在进行着通过购来发展壮大的崭新尝试。
我国企业股权高度集中、国有股一股独大以及代理问题的存在，除了企业自身发展需求外，管理者和政府亦是推动我国上市公司进行并购的主要原因。
2009年，吴静在《我国企业并购动因分析》一文中提到除了企业发展需求动因外，政府绩效动因在企业并购动机中也占有很大比重，“壳”资源（上市公司的壳资源对企业是一种可以用来低成本再融资的工具，对地方政府是政绩工程的重要评价指标）分配，以及政府为提高政绩推行体制改革。
无论从宏观和微观层面分析还是从企业自身与社会环境分析，我们可以看出，并购的动因并不是完全孤立的，它们之间有横纵交叉的错综关系。
二、企业并购的风险分析
近几年来，随着我国市场经济体制的建立和完善，企业间的并购行为更加频繁，并购的规模和领域不断扩大，并购的环境日趋复杂，并购的风险也日益加剧。
2002年张建华在《企业并购风险分析与风险管理》把企业并购面临的风险分为以下十种：政策风险，财务风险，整合风险，体质风险，法律风险，委托—代理关系失控风险，产业风险，反并购风险，投机风险，信息不对称风险。
2006年，胥朝阳在《企业并购风险的因素识别与模糊度量》中将模糊数学的理论和方法引入并购风险的度量，把企业并购的风险划分为以下十种：并购战略，法律环境，政府角色，产权市场，体质因素，信息对称性，资产评估，并购价格，融资与支付方式，企业文化。
2006年，王太顺在《企业并购财务风险产生的原因及控制途径》则提出企业并购的财务风险主要是由于并购估价不准确，并购支付方式不恰当，并购融资不合理，并购整合效率低等原因所引起的。
上述对企业并购的观点虽有所差异，但是我们可以看出，他们都强调了企业自身融资方式、支付方式、及并购目的，信息的对称性，政府的政策等因素。
综合以上观点我们可以把企业并购的风险因素归结为以下几个方面：营运风险，财务风险，信息风险。
企业并购是一项复杂的系统工程，具有高风险特征，有效管理并购风险非常重要。
2006年，王太顺在《企业并购财务风险产生的原因及控制途径》中提出应该谨慎选择并购目标企业、合理确定目标企业的价值、选择合适的并购支付方式、做好融资安排，合理确定融资结构。
企业并购有很多风险因素，2006年，杨明君在《企业并购的信息风险及其防范》中对信息风险的防范做了探讨，提出了签订保密协议，信息披露及保证，信息审查评鉴重点，涉及债务风险防范技巧得建议。
此外，针对财务风险，规范的体制保证，科学的风险管理机制，精心策划、慎重选择并购目标和并购方式，与银行等融资机构的合作，卓越的并购整合
工作等也能起到防范风险的作用。
三企业并购的会计方法选择
企业并购的会计方法选择一直是会计学界最有争议的问题之一。
目前比较通用两种方法是购买法与权益结合法。
以下文献对这两种方法的选择做了探讨。
2004年,杨有红在《并会计处理购买法与权益结合法》中提出：购买法是一个被广泛接受的科学方法。
并购会计方法选择的焦点在于是否允许采用权益结合法。
他认为：（一）权益结合法可以成为合法运用的会计方法(二)对权益结合法的运用条件做出明确、具体、无懈可击的规定。
2006年，肖云龙在《企业并购的会计方法选择》中对两种方法的原理进行了探讨，并比较了两种方法在操作过程中的差异。
他认为，会计方法的选择应重实质而非形式，就我国目前市场经济的发展看，企业并购特别是换股合并会越来越多，权益结合法的使用有其广泛的业务基础。
然而，随着市场经济的不断完善，中国会计也应及早真正地与国际接轨。
同时，随着产权交易制度的完善和资产评估业的不断发展，公允价值的准确性也会逐步提高，权益结合法的弊端在我国会越来越显露出来，而购买会计法则是较为长久、科学的方法。
综上，我们可以看出，企业并购会计方法的选择应注重实质而非形式, 我国目前允许收购法和权益结合法并存的局面是有其经济动因的。
但是,随着我国市场经济的不断完善,被并购企业净资产公允价值的确定能保证公正合理的时候, 权益结合法的废除之日也将随之而来。
结论
通过对企业并购的动机、风险因素及防范、会计方法的选择的分析，可以知道：企业并购的原因是错综复杂的，可以归纳为企业自身和社会环境两种因素。
企业并购也面临着众多风险，为了有效防范风险需要采取相应的措施。
企业并购的会计方法选择应该重实质而非形式，目前在我国收购法和权益结合法是并存的。
