Abstract

Since the catering enterprises actively developed in china, our team chooses one of the catering restaurants, Xiao Mila, located in the Liu Lang bay, closed to the east gate of SWUFE. It looks crowded and not very comfortable for eating hot pot. However, it is still very popular and competitive outside the East Gate and has a lot of regular customers. We decided to find out reasons for this odd phenomenon. As it is a typical catering restaurant in that area, the research gives us in-depth knowledge of catering restaurant in college student living area.

Our article uses systematic research towards the operating condition of Xiao Mila. Our aims are to understand the in dividual catering businesses? operating condition, and at the same time supplement economic research, respond to our national twelfth five-year development plan, provide guidance for other catering enterprises. The investigative manner of this article is through the issuance of the form of questionnaire survey to the crowd who ate in the Xiao Mila. After the investigation, we use the statistics we got to analyze the research questions. The methods of analysis are quantitative analysis and qualitative analysis, the Comparative Method

Our conclusions of the reasons for Xiao Mila?s success are its unique flavor, locality, and low price and its awesome reputation among students; the shortages of this restaurant are its inefficient service and poor sanitation. Our team also gets the conclusion that different in gender groups have different attitude towards to Xiao Mila. This difference do not only indicate the difference in female?s and male?s thinking patterns, but also point out the way for Xiao Mila to attract customers of a certain gender. Then through discussion, we come up with a suggestion that it should overcome its shortages while holding on to its best position in flavor and price.

1. Introduction

Along with the economy development and people's living standard improving, our tertiary industry especially catering industry is developing vigorously. Especially those young, good-tasted college students with appreciating ability,

enjoyment demand, time and relatively plenty of money, have an increasing demand for catering. Canteen cannot satisfy their requirement, so the snack bars outside the university are developing prosperously. As one of the most popular restaurants among these shops, Xiao Mila?s business model has strong research significance. It is located in the Liu Lang bay, closed to the east gate of SWUFE. It uses the form of buffet soup pot. With paying ten Yuan, everyone can get a gift dish and can get vegetables freely. As a shop with only two other shops, it has many customers. But the national twelfth five-year development planning emphasizes the development of the service industry. Therefore, the study of Xiao Mila?s operati on state, is of great significant not only for economic research theory but also for the individual food businesses.

This paper aims to have systematic research towards the operating condition of Xiao Mila. We investigate many factors such as the food taste, environment of dieting, health, location and so on, which appeal to typical customers like our college students. So as to understand the individual catering businesses? operating condition, and at the same time supplement economic research ,respond to our national twelfth five-year development plan, provide a guidance for other catering enterprises.

This paper are divided into eight parts, respectively is the introduction, literature review, research method, data analysis and conclusions and enlightenment, references and appendix. We hope it can fully display Xiao Mila?s performance!

2. Literature review

Since 1988, catering enterprises in China have actively explored the markets and promoted the popularization of the development of food industry and its development. Xiao Mila as a new local catering mode, there has been no person to do research on it. But from the former researches about catering enterprises we can see the reasons of Xiao Mil a?s prosper ity. After the analysis about modern diners? consu mption psychology, Swiss expert concluded the tendency of food consumption. In the report, he pointed out that customers are more inclined to the restaurant of high quality but low costs, has various options and can enjoy with families and friends. I n Chi Jin?s report in 2000, our dining market should pay more attention to level marketing. That is to change products appropriately to generate new use, new situation and new target market to create new categories, thus to redefine markets and create new requirements and value. So new type of catering mode like Xiao Mila can easily be accepted an loved by people. As Li Muming said in his report that the best way to attract customers is to be special.

3. Methodology

3.1 The proposing of problem and hypothetic

The report is aimed at analyzing of the management of Xiao Mila, a restaurant serving hot pot near SWUFE campus. In our first year in SWUFE, we made Xiao Mila a regular place for dining and having a treat. As we getting familiar with the small restaurant, we found it really below the standard of catering enterprises. However, it is still very popular and competitive outside the East Gate and has a lot of regular customers. We decided to find out reasons for this odd phenomenon.

3.2 The selecting of research method

Considering the actual situation and operability, we used random sampling survey to do the research. The survey had been done on May.22 2011 in Southwestern University of Finance and Economic .150 questionnaires were handed out, via Sojump and also in the class meeting of International Trade and Business. 127 questionnaires were collected and 86 of them were valid. The percentage of valid questionnaires is 67.7%.

4. Sample and data analysis

4.1 Pre-investigation

To test the validity of our questionnaires, we did an analysis for pre-investigation. During the process of pre-investigation, we asked students some questions about our questionnaires to know whether our questionnaires are easy to understand .Then we revise our questionnaires according to students? precious suggestions.

The possible reasons for the imperfect questionnaire are three. First, we?re supposed to use the quantitative research mode, but we didn?t. So we gave people too much choice that it was difficult for them to choose answers and for us to collect data. Second, we didn?t organize the questions well. We didn?t divide them into several types. So it was difficult for us to analyze the answers. Last, the questi on types weren?t enough for us to do the research of Xiao Mila systemically

themselves without spending too much money, and it is also more convenient, healthy and cheap.

5. Results and discussion

After the analysis, there are many factors that influence the operation of Xiao Mila. In general, it is affected by its flavor, price, location, decoration, service attitude, sanitation, customers? gender, food types, reputation.

From the tabl e analysis, we can see grade, gender and address affect people?s choice of the answers. From the SWOT analysis, we can see the advantages and disadvantages of Xiao Mila and conclude the opportunity and threat in its development.

6. Conclusion

6.1 Summary

a. From the statistic we analyzed, we can draw the conclusion that the

success of Xiao Mila is directly related to its unique flavor, low price and its awesome reputation among students.

b. What hold Xiao Mila back from getting greater success is its inefficient

service and poor sanitation. The statistic illustrates that more than two thirds of students are more or less dissatisfied with the service Xiao Mila offered and food sanitation.

c. When it comes to the distance of Xiao Mila to the dormitory, the results

differ a lot in terms of the different location of dormitory. From the statistic, it is obvious that students who live in the dormitory near the north gate have

a greater dissatisfaction of Xiao Mila?s location than students who live in

dormitory near the east gate.

d. As the results of the questionnaire indicated, the decoration of the

storefront doesn?t have a obvious impact on the Xiao Mila?s operation. Most of the students we researched feel indifferent about the decoration of the storefront.

e. In addition, we find out there is subtle difference in differ ent gender?s

attitude towards Xiao Mila: females are more dissatisfied with the poor sanitation and inefficient service than males, whereas males are more dissatisfied with the flavor of the soup pot. This difference do not only indicates the difference in female?s and male?s thinking patterns, but also point out the way for Xiao Mila to attract customers of a certain gender.

f. According to the result of our questionnaires, we can see that the situation

Xiao Mila is in is quite paradoxical. On the one hand, Xiao Mila is not that perfect, for students are not satisfied with it in many aspects, especially the aspects of its poor sanitation and service. On the other hand, despite of its numerous weaknesses, Xiao Mila?s special flavor and unfair advantage of its low price and still attract a lot of customers. If Xiao Mila wants to push its business to a higher level, it should overcome its shortage while holding on to its best position in flavor and price.

6.2Suggestion

6.2.1 About hardware

a. Expand the restaurant area to contain more people. Rent the nearing

storefront or transform the table setting to make space.

b. Improve the decoration to create a more comfortable environment.

c. Focus on the sanitation of the whole restaurant, especially the tables and

around the food shelves.

6.2.2 About software

a.Improve the variety and cleanness of food to meet the catering standard.

b.Adopting employee training program to make them behave appropriately and

work with enthusiasm and efficiency.

6.3Implication

We can find an indication through the analysis of the research. In the catering market, which has a variety of types, we can conclude that restaurant owners are not able to determine the consumption level but they are able to attract and keep customers by many other means. The Xiao Mila doesn?t have rare ingredients or elegant decoration to attract customers. But it has successfully exerted popularity among innumerable college students. The college students are willing to queue for a long time to have meal in Xiao Mila. Just like a senior student in SWUFE said: “If you haven?t been to Xiao Mila, you are likely to be out of fashion.” We have to say, indeed, Xiao Mila has performed successfully in catering market. And we can get many indications from it.

In contemporary society, the catering industry is weak. Developing all kinds of luxury food, spending a big deal of money on advertising, and using all kinds of spices to make food more delicate, Traders have tried their best to attract customers. However, customers always only just have a try on their luxury food and then give it up. The reason is not that customers cannot afford the high price but they are afraid of the food which is full of unhealthy unknown spice. In this point, Xiao Mila does a great job. Its ingredients are both cheap and healthy. We can find that people turn to choose food that is good for their health and of a reasonable price. With its unique way, Xiao Mila wins more and more customers? hearts and establishes itself securely in position.

In addition, compared with Ye Dian Xiao Mila, Zhu Juan Xiao Mila has perfect location. This example perfectly explains that as to a catering enterprise, accurate market positioning and realistic analysis do make a great sense to its success.

Furthermore, not only for Xiao Mila, but also for whole catering industry,to attract more diners,the enterprises must assure their customer groups and position customer market. And they had better attach more importance to innovation, paying more attention to healthy food and its flavor. Only in this way can they fascinate new customers while keeping old customers and promote their catering brand.

Also, we found some problems in our research of Xiao Mila. A lot of students complain about its poor service and terrible sanitation. Because there is only one cook in Xiao Mila, serving speed becomes its Achilles? heel. If those problems stay unsolved, even Xiao Mila?s magical flavor cannot stop it from

stepping into its own grave. This potential dilemma also reminds other catering enterprises to establish a complete system of service and pay more attention to the division of labor and cooperation.

6.4 Shortage

In this research, we get samples from students of SWUFE, while the research result is not common enough. As a liberal arts college, there is a low proportion of male students. And compared with female students of science academies or engineering college, the female students here are keener on perusing delicious food.

Next, we handed out 127 pieces of questionnaire while only 86 pieces of them are valid. What?s worse, most of the samples are from dormitory area which is close to the east gate, which made the research some limitations.

In the process of analyzing, as lacking of professional knowledge, we are incapable of using a more advanced research method

Abstract Since the catering enterprises actively developed in china, our team chooses one of the catering restaurants, Xiao Mila, located in the Liu Lang bay, closed to the east gate of SWUFE. It looks crowded and not very comfortable for eating hot pot. However, it is still very popular and competitive outside the East Gate and has a lot of regular customers. We decided to find out reasons for this odd phenomenon. As it is a typical catering restaurant in that area, the research gives us in-depth knowledge of catering restaurant in college student living area. Our article uses systematic research towards the operating condition of Xiao Mila. Our aims are to understand the in dividual catering businesses? operating condition, and at the same time supplement economic research, respond to our national twelfth five-year development plan, provide guidance for other catering enterprises. The investigative manner of this article is through the issuance of the form of questionnaire survey to the crowd who ate in the Xiao Mila. After the investigation, we use the statistics we got to analyze the research questions. The methods of analysis are quantitative analysis and qualitative analysis, the Comparative Method Our conclusions of the reasons for Xiao Mila?s success are its unique flavor, locality, and low price and its awesome reputation among students; the shortages of this restaurant are its inefficient service and poor sanitation. Our team also gets the conclusion that different in gender groups have different attitude towards to Xiao Mila. This difference do not only indicate the difference in female?s and male?s thinking patterns, but also point out the way for Xiao Mila to attract customers of a certain gender. Then through discussion, we come up with a suggestion that it should overcome its shortages while holding on to its best position in flavor and price. Keywords Xiao Mila; College Students; Consumption; Analysis; SWOT 1. Introduction Along with the economy development and people's living standard improving, our tertiary industry especially catering industry is developing vigorously. Especially those young, good-tasted college students with appreciating ability,

CHAPTER 15 西北研究院蔡嘉驰131246 15.4 (i) What we choose is part of u t. Then gMIN t and u t are correlated, which causes OLS to be biased and inconsistent. (ii) I think it is uncorrelate because gGDP t controls for the overall performance of the U.S. economy. (iii) The change of U.S. minimum may someway change the state minimum and vice versa. If the state minimum is always the U.S. minimum, then gMIN t is exogenous in this equation and we would just use OLS. 15.7 (i) Because students that would do better anyway are also more likely to attend a choice school. (ii) Since u1 does not contain income, random assignment of grants within income class means that grant designation is not correlated with unobservables such as student ability, motivation, and family support. (iii) The reduced form is choice= π0 + π1faminc + π2grant + v2, and we need π2≠ 0. (iv) The reduced form for score is just a linear function of the exogenous variables: score= α0 + α1faminc + α2grant + v1. This equation allows us to directly estimate the effect of increasing the grant amount on the test score, holding family income fixed.So it is useful.

1、对未分组资料频数分析 从中国统计局中获得从11月21日至30日国内50个城市主要食品平均价格变动情况,以该数据为例为例,进行频数分析。 首先输入数据: 选择Analyze中Descriptive Statistics——Frequencies,打开Frequencies对话框;将需处理的变量键入变量框中

单击Statistics…按钮统计量子对话框12指标,选中所需要计算的指标: 单击Charts …按钮,选择需绘制的统计图: 单击OK按钮开始运行,运行结果为:

从上图中可以看出数据中缺失值为0,花生油的平均价格104.84是最高的,而巴氏牛奶的平均价格1.81最低,全部食品平均价格的平均数为16.5327,标准差为22.4668,各种食品的平均价格差距较大。

条形图、饼形图以及直方图是用不同的图形表示方法来说明数据的指标,其实质是一样的,从图中可以看出平均价格在0—22元之间的食品是最多的,20—40元之间的食品数次之,接下来是40—60元之间的食品,不存在平均价格在60—100之间的食品。 2、以食品平均价格为依据对数据进行分组并对分组后的数据进行频数分析: Transform —Recode—Into same V ariables ,将要分组的变量放入Numeric 栏中,单击Old and new V alues分组:

SPSS软件应用第四讲

《SPSS软件应用》教案 ●复习一:数据库结构建立 ●复习二:数据合并 ●复习三:定距数据的分组 有两种方法:一是在transform下的visual bander(可视离散化)栏完成;一是在transform转换中的compute计算变量来完成。 由于Computer需要自己定义变量标签,Visual Bander直接选择显示变量标签,因此在分组的时候,通常采取Visual Bander来实现。 第四讲数据编码和计数 教学原因:由于录入好的数据,有时候并不能够直接用来分析,因此需要对变量进行重组或者称为转换,将数据重新编码、组合等; 教学目的:培养学生根据研究主题的需要,对变量数据进行转换。 教学内容:对数据进行重新编码和计数。 一、Recode的重新编码功能 功能:用于从原变量值按照某种对应关系生成新变量值,可以将新值赋给原变量,也可生成新变量。 如果是13.0,则实现路径:Transform——Recode——into the same variables(编码为相同变量)/into different variables(编码为不同变量);如果是16.0及以上,则直接是Transform——recode into different variable。我们一般要求重新编码为一个新变量,目的是为了保持原有变量数据。

[例题:对自己的受教育情况(a6.1)的变量值重新编码为高中低] 解释:原变量的取值是如下,因此,我们可以考虑将1-3设置为低教育程度,4-6设置为中等教育程度,7及以上设置为高等教育程度。 具体实现过程: 第一步,单击Transform——recode into different variables( SPSS 13.0使用)或Recode into different variable (重新编码为不同变量时,16.0及以上使用)时,出现下窗口: 第二步,将左边的变量(自己的受教育情况)选中,然后移入右边Input variable →output variable( 输入变量→输出变量) 空白栏中,具体如下图所示:

SPSS调查报告 - 期末作业

---------------------------------------------装--------------------------------- --------- 订 -----------------------------------------线---------------------------------------- 班级 姓名 学号 - 广 东 财 经 大 学 答 题 纸(格式二) 课程 数据处理技术与SPSS 20 15 -20 16 学年第 1 学期 成绩 评阅人 评语: ========================================== (题目)关于本部学生对收费代课现象支持度的调查报告 (正文) 一、调查背景 如今,大学生逃课现象屡见不鲜,随之衍生了“收费代课”的现象。据了解,在全国近百所高校中,存在“收费代课”现象的高校居然有一半之多。当“收费代课”现象衍变成了一种行业,成为有领导、有组织、有规模、有纪律的机构,不仅仅应当引起社会的关注,更应引起校方对教育方式的深刻反思。“有偿代课”作为一种不正常的校园现象,有其存在的社会土壤,其原因有多方面,值得让人对当前大学教育深思。在“收费代课”现象蔚然成风之时,我们学校的学生们也加入了这支大队伍。对于这样的一种收费代课的行为,同学们褒贬不一,每个人都有自己的看法。然而,这种行为经常在我们的身边发生着,无疑应该引起我们的关注,并引发我们的深思,形成一定的判别能力与认知能力。

二、调查目的 我们希望通过本次调查了解广东财经大学本部学生选择收费代课的原因,以及对本专业学习、实习实践的认知程度,是否支持放弃学习去实习或者做自己的事情,是否支持收费代课。同时,我们也希望通过这份调查报告揭露出的一些情况,一方面,帮助学生更好地权衡学习与实习的利弊,更加理性地对待收费代课的行为,做出对自己正确合适的选择;另一方面,引起学校对这种收费代课现象的重视,给学校提一些建议,希望学校采取一些措施改善这种不良校风。 三、调查方法 从可行性角度出发,本次调查采用非概率随机抽样的街头拦截法,集中对象为本部大三大四的同学,以自愿形式对本部同学分发调查问卷,总共发出80份问卷,回收80份,有效问卷80份。收集问卷之后,利用spss软件进行数据整理与分析,最后把结论整理成调查报告。调查报告中采用的数据分析方法主要有:频数分析、多选项分析、交叉列联表行列变量间关系的分析、单因素方差分析等。 四、描述统计 1、对样本性别作频数分析 从上表可以看出,这次填写问卷的女生较多,占了样本的66.3%,这与我们学校男女比例不均衡有很大的关系,样本的男女比例不相等,也可以较好地接近学校的实际情况,有利于我们得到更为准确的结论。 2、对样本年级作频数分析 从上表可知,参加问卷调查的大三大四学生比例明显比较高,这与一开始我们预期相符,样本中大三大四学生所占比例较多,有利于我们得到更为有针对性的结论。

我国区域农业经济聚类分析 一、提出问题 农业是通过培育动植物生产食品及工业原料的产业,是支撑国民经济建设与发展的基础产品。农业问题的本质及其重大意义。农业是国之根本,它的发展关系到其他两大产业的繁荣与否。与此同时,面对复杂多变的国内国际政治、经济环境,中国在农业方面的基础地位日渐薄弱。然而,在强劲的GDP增速背后,农民的收入水平却提高不够。由于受自然、经济等因素的影响,农业发展具有很强的区域性。不同地区农业发展水平发展方式很是不同。对区域农业进行聚类分析对针对性的制定区域农业发展战略政策有很强的指导性。 二、数据收集 为了对我国区域农业经济进行聚类分析,这里选择与区域农业发展相关的11个评价指标,它们分别代表农业发展的总量方面,水利设施、除涝面积方面,家庭土地经营方面。具体而言,总量方面包括地区生产总值x1(亿元),农业生产总值x2(亿元);水利设施、除涝面积方面包括水库数x3 座),水库总容量x4(亿立方米),除涝面积x5(千公顷),水土流失治理面积x6(百万元)四项;家庭土地经营方面包括经营耕地面积x7(亩/人),经营山地面积x8(亩/人),园地面积x9(亩/人)、牧草地面积x10(亩/人)、养殖水面面积x11(亩/人)五项。 这些指标中国统计年鉴上取得,其原始数据如表1 。 表1 房地产业发展水平的原始数据 地区x1 x2 x3 x4 x5 x6 x7 x8 x9 x10 x11 北京14113. 58 124.36 82 93.8716 149.77 542.8 0.5335 0.061 0.140 6 0.053 9 天津9224.4 6 145.58 28 26.21342 9 377.22 46.43 1.4862 0.006 5 0.024 8 0.037 河北20394. 26 2562.8 1 1066 161.3647 2 1648.6 4 6290.31 1.981 0.118 1 0.079 4 山西9200.8 6 554.48 733 57.53152 6 89.13 5352.495 2.4314 0.034 8 0.200 7 0.0079 内蒙古11672 1095.2 8 497 167.891 277 10897.47 9.6537 0.232 2 0.021 9 126.75 57 辽宁18457. 27 1631.0 8 951 359.2693 6 985.25 3 6333.716 3.4984 0.197 4 0.084 7 0.039 6 吉林8667.5 8 1050.1 5 1643 320.3943 17 1021.4 3586.565 7.7491 0.135 7 0.020 1 黑龙江10368. 6 1302.9 913 178.7056 3334.9 4690.5 11.678 1 0.009 5 0.005 3 0.0217 上海17165. 98 114.15 55.35 0.2826 0.046 5 0.052 9 江苏41425. 48 2540.1 910 189.1796 59 2802.5 06 1052.269 1 1.1232 0.008 9 0.017 8 0.142 8 浙江27722. 31 1360.5 6 4217 398.0666 96 496.71 2431.64 0.6027 0.425 5 0.152 3 0.059 安徽12359. 33 1729.0 2 4819 326.5100 56 2269.0 5 2136.082 1.8662 0.336 7 0.048 1 0.107 2 福建14737. 12 1363.6 7 3225 185.3876 2 129.58 3 1470.802 6 0.8831 1.235 9 0.290 3 0.089 3 江西9451.2 6 1206.9 8 9809 293.7193 72 375.71 5 4514.041 62 1.6078 1.047 9 0.064 7 0.049 2 山东39169. 92 3588.2 8 6291 227.6167 92 2651.8 4651.521 1.5554 0.042 7 0.101 7 0.014 2 河南23092. 36 3258.0 9 2352 402.2094 67 1958.9 7 4428.695 1.68 0.023 8 0.034 0.007 5 湖北15967. 61 2147 5848 992.1486 1219.1 71 4666.472 1.6932 0.668 8 0.053 4 0.127 5 湖南16037. 96 2325.5 1209 2 402.29 3 486.3 4 2898.99 5 1.2504 0.531 2 0.074 4 0.0259 0.056 7 广东46013. 06 2286.9 8 7437 429.0038 88 514.49 1378.454 0.6475 0.308 8 0.117 2 0.069 7 广西9569.8 5 1675.0 6 4367 378.4462 97 209.57 2 1873.769 3 1.4335 0.641 1 0.142 9 0.0331 0.022 2 海南2064.5 539.83 996 100.0175 17.513 32.726 1.2842 0.818 7 0.577 3 0.024 5 重庆7925.5 8 685.38 2840 74.06409 3 2312.33 1.1854 0.343 9 0.066 1 0.005 0.019 2 四川17185. 48 2482.8 9 6759 214.9343 93.98 6329.638 1.0835 0.264 5 0.048 2 0.025 8
