【摘要】：我國企業(yè)并購活動(dòng)的日益增多表明，并購在我國社會(huì)經(jīng)濟(jì)活動(dòng)中發(fā)揮著越來越重要的作用。并購動(dòng)因明確是保證并購成功的首要因素，因此，本文研究目的在于找出我國上市公司進(jìn)行并購的動(dòng)因所在，建立回歸模型對(duì)并購動(dòng)因與并購績效之間的相關(guān)性進(jìn)行驗(yàn)證，并采用EVA經(jīng)濟(jì)增加值評(píng)價(jià)指標(biāo)體系對(duì)各個(gè)并購動(dòng)因下上市公司并購績效變化趨勢進(jìn)行研究，分析其并購績效改善或者惡化的原因，為上市公司并購重組提供一定的借鑒，為改善我國上市公司整體并購績效提供一定的參考。 首先，本文在對(duì)國內(nèi)外學(xué)者關(guān)于并購績效研究的基礎(chǔ)上，從并購和并購績效概念的角度出發(fā)，提出本文的研究內(nèi)容和結(jié)構(gòu)框架。 其次，在各并購績效理論的基礎(chǔ)上，并結(jié)合我國企業(yè)的實(shí)際并購狀況，從主要和次要兩個(gè)方面分析了我國上市公司的并購動(dòng)因，并針對(duì)其中3個(gè)最主要?jiǎng)右蛱岢鱿鄳?yīng)的研究假設(shè)和回歸模型，以期得到較理想的并購績效。 再次，本文實(shí)證研究部分以2006-2007年發(fā)生的并購事件為研究樣本，首先驗(yàn)證EVA指標(biāo)法的有效性，其次從上市公司并購績效的整體變化趨勢角度，對(duì)各并購動(dòng)因與并購績效之間的相關(guān)性進(jìn)行實(shí)證分析，最后采用EVA指標(biāo)對(duì)各并購動(dòng)因與并購績效之間的關(guān)系進(jìn)行實(shí)證研究，并得到以下結(jié)論：（1）并購使得上市公司整體并購績效得到改善且效果較為顯著；（2）規(guī)模經(jīng)濟(jì)動(dòng)因下，上市公司并購績效較并購前得到顯著改善；（3）多元化經(jīng)營動(dòng)因下，上市公司并購績效較并購前有所改善，但不如規(guī)模經(jīng)濟(jì)動(dòng)因下的并購績效改善顯著；（4）拓寬融資渠道動(dòng)因下，上市公司并購績效惡化，較并購前相比，企業(yè)并購績效出現(xiàn)負(fù)增長現(xiàn)象。 最后，從并購企業(yè)和政府監(jiān)管部門兩個(gè)角度，提出了規(guī)范并購可行性分析、加強(qiáng)并購企業(yè)整合力度、適當(dāng)減少政府不當(dāng)干預(yù)、強(qiáng)化上市公司信息披露制度等建議，，以期改善上市公司并購績效。
[Abstract]:The increasing number of M & A activities in China indicates that M & A plays a more and more important role in China's social and economic activities. The clear motivation of M & A is the primary factor to ensure the success of M & A. Therefore, the purpose of this study is to find out the motivation of M & A of listed companies in China, and to establish a regression model to verify the correlation between M & A motivation and M & A performance. And using the EVA economic value added evaluation index system to study the trend of M & A performance of listed companies under various M & A motivation, analyze the reasons for the improvement or deterioration of M & A performance, and provide a certain reference for M & A restructuring of listed companies. In order to improve the overall M & A performance of listed companies in China to provide a certain reference. First of all, based on the domestic and foreign scholars' research on M & A performance, from the perspective of M & A and M & A performance concept, this paper puts forward the research content and structure framework of this paper. Secondly, on the basis of the theories of M & A performance and the actual situation of M & A of Chinese enterprises, this paper analyzes the causes of M & A of listed companies in China from two aspects: main and secondary. The corresponding research hypotheses and regression models are put forward according to the three main motivations in order to get the ideal M & A performance. Thirdly, the empirical research part of this paper takes the M & A events in 2006-2007 as the research sample, first validates the effectiveness of the EVA index method, and secondly, from the perspective of the overall trend of M & A performance of listed companies. The correlation between M & A motivation and M & A performance is analyzed empirically. Finally, the relationship between M & A motivation and M A performance is studied by using EVA index. The conclusions are as follows: (1) M & A improves the overall M & A performance of listed companies and the effect is significant; (2) under the motivation of scale economy, the M & A performance of listed companies has been improved significantly compared with that before M & A; (3) the M & A performance of listed companies is better than that of before M & A, but the M & A performance of listed companies is less significant than that of economies of scale. (4) under the motivation of widening the financing channels, the M & A performance of listed companies deteriorates, compared with that before M & A, the performance of M & A shows negative growth. Finally, from two angles of M & A enterprise and government supervision department, the paper puts forward some suggestions, such as standardizing the feasibility analysis of M & A, strengthening the integration of M & A enterprises, appropriately reducing the improper government intervention, strengthening the information disclosure system of listed companies, and so on. In order to improve the performance of mergers and acquisitions of listed companies.
