【摘要】：20世紀50年代美國的一位戰(zhàn)略管理專家Ansoff提出了企業(yè)多元化經(jīng)營的概念，自此之后，多元化經(jīng)營逐漸被世界眾多經(jīng)濟發(fā)達國家實踐運用，，被引用為提高資本使用效率、規(guī)避風(fēng)險、增加企業(yè)利潤、擴大企業(yè)規(guī)模的有效手段。多元化經(jīng)營主要采取開發(fā)新產(chǎn)品，或者吸收、合并行業(yè)外的公司，或者重組公司內(nèi)部產(chǎn)品結(jié)構(gòu)等經(jīng)營模式。 然而多元化經(jīng)營對企業(yè)產(chǎn)生的效應(yīng)問題一直是各界學(xué)者關(guān)注的熱點問題，也是一個存在著極大爭議的話題。多元化經(jīng)營與財務(wù)績效之間存在怎樣的關(guān)系，各界學(xué)者之間沒有達成共識，不同行業(yè)之間往往存在不同的結(jié)論。 本文選擇作為國民經(jīng)濟支柱產(chǎn)業(yè)的建筑業(yè)上市公司作為研究對象。以2011年至2013年滬深兩市的建筑行業(yè)上市公司為樣本，探討多元化經(jīng)營與企業(yè)財務(wù)績效之間的關(guān)系，主要包括兩部分，第一部分探討多元化程度與企業(yè)財務(wù)績效的關(guān)系；第二部分探討不同多元化類型與財務(wù)績效的關(guān)系。本文選用熵指數(shù)作為度量多元化程度的指標，選用總資產(chǎn)收益率、每股收益、資產(chǎn)負債率、速動比率等指標從盈利能力、償債能力兩方面評價財務(wù)績效，并選擇了企業(yè)規(guī)模、第一股東持股比例、公司成長能力等指標作為控制變量，通過構(gòu)建財務(wù)績效指標與熵指數(shù)以及控制變量之間的多元線性回歸模型進行實證分析，得出我國建筑業(yè)企業(yè)多元化程度與財務(wù)績效之間存在負相關(guān)關(guān)系的結(jié)論；并構(gòu)建了代表是否為相關(guān)多元化經(jīng)營的虛擬變量，對不同多元化類型下的財務(wù)績效進行描述性分析以及回歸分析，得出我國建筑業(yè)相關(guān)多元化企業(yè)財務(wù)績效高于非相關(guān)多元化企業(yè)財務(wù)績效的結(jié)論。 本文通過對建筑業(yè)上市公司進行實證分析，得出結(jié)論，我國建筑業(yè)上市公司實施多元化，并不一定會帶來良好的經(jīng)濟效益，反而有可能降低財務(wù)績效。
[Abstract]:In the 1950s, Ansoff, a strategic management expert in the United States, put forward the concept of diversification of enterprises. Since then, diversification has been gradually applied by many developed countries in the world and cited to improve the efficiency of capital use. Avoid risk, increase enterprise profit, expand the effective means of enterprise scale. Diversification mainly adopts developing new products, absorbing and merging companies outside the industry, or restructuring the internal product structure of the company. However, the effect of diversification on enterprises has always been a hot issue that scholars from all walks of life pay close attention to, and it is also a controversial topic. What is the relationship between diversification and financial performance, scholars from all walks of life do not reach a consensus, and different industries often have different conclusions. This paper chooses the listed companies of the construction industry as the pillar industry of national economy as the research object. Taking the listed companies of construction industry in Shanghai and Shenzhen stock markets from 2011 to 2013 as samples, this paper discusses the relationship between diversification and enterprise financial performance, including two parts. The first part discusses the relationship between diversification degree and enterprise financial performance. The second part discusses the relationship between different diversification types and financial performance. In this paper, entropy index is chosen as the index to measure the degree of diversification, and the total return on assets, earnings per share, asset-liability ratio and quick ratio are selected to evaluate the financial performance from two aspects of profitability and solvency, and the scale of the enterprise is chosen. The first shareholder's shareholding ratio and the growth ability of the company are taken as control variables, and the multiple linear regression model between financial performance index, entropy index and control variable is constructed to carry out empirical analysis. The conclusion that there is a negative correlation between the degree of diversification and financial performance of construction enterprises in China is drawn, and the fictitious variable whether the representative of diversification is related to diversification is constructed. Based on the descriptive analysis and regression analysis of the financial performance of different diversification types, the conclusion is drawn that the financial performance of the diversified enterprises in construction industry is higher than that of the non-related diversified enterprises. Based on the empirical analysis of listed companies in construction industry, this paper draws a conclusion that diversification of listed companies in construction industry in China will not necessarily bring good economic benefits, but may reduce financial performance.
