【摘要】：改革開放三十年以來，我國的資本市場不斷發(fā)展壯大，企業(yè)對資金的需求也越來越多，首次公開募股（Initial public offering，以下簡稱IPO）作為資金融通渠道之一，已經(jīng)成為我國企業(yè)籌資的最重要手段。企業(yè)通過上市獲得了大量資金，而上市后的企業(yè)，規(guī)模不斷地擴大，卻存在著資金使用效率不高、財務(wù)比率指標不盡人意的現(xiàn)象。我們通過對以往文獻的整理后發(fā)現(xiàn)，無論是發(fā)達國家的資本市場還是亞洲的新興市場，均存在IPO后經(jīng)營績效下降的現(xiàn)象。 本文選取了2010年和2011年在我國主板上市的公司為樣本，采用了盈利能力、營運能力、償債能力以及成長能力四類共七項財務(wù)指標作為企業(yè)經(jīng)營績效的衡量指標，并在此基礎(chǔ)上運用專家賦權(quán)法構(gòu)造出綜合指標來考察企業(yè)的經(jīng)營績效。針對各單一指標及綜合指標，我們運用統(tǒng)計分析并配以雙尾配對T檢驗的方法，證實了我國主板市場確實存在“IPO效應(yīng)”，并且，無論上市公司是否有風險投資背景或者處于哪種行業(yè)，均呈現(xiàn)出不同程度的IPO效應(yīng)；隨后，我們運用了單因素方差F檢驗及單變量多因素方差檢驗F檢驗對不同風險投資背景樣本組和不同行業(yè)樣本組分別進行了實證研究，結(jié)果發(fā)現(xiàn)，IPO后，只有償債能力顯著變好，而主板上市公司的盈利能力、營運能力和成長能力均有所下降；另外，，無論是IPO前還是IPO后，有風投背景的上市公司經(jīng)營績效都優(yōu)于無風投背景的上市公司，且在IPO后，有風投背景的上市公司在資產(chǎn)負債率和流動比率上顯著優(yōu)于無風投背景的上市公司。從行業(yè)上來看，不同的行業(yè)對企業(yè)IPO前后經(jīng)營績效的變化具有一定的影響。 最后，我們對如何降低IPO效應(yīng)提出了建議。
[Abstract]:Since the reform and opening up three decades ago, the capital market of our country has been developing continuously, and the demand for capital by enterprises is also increasing. Initial public offering (IPO) is one of the financing channels. It has become the most important means for enterprises to raise funds in our country. Enterprises have obtained a lot of funds through listing, but after listing, the scale of enterprises has been expanding constantly, but there is not high efficiency in the use of funds. The financial ratio index is not satisfactory. We find that there is a decline in operating performance after IPO in both the capital markets of developed countries and the emerging markets of Asia through the collation of previous literatures. This paper selects the companies listed on the main board of our country in 2010 and 2011 as samples, and adopts four kinds of financial indexes, namely profitability, operating ability, solvency and growth ability, as the measurement index of business performance. On the basis of this, a comprehensive index is constructed by using the expert weighting method to evaluate the business performance of the enterprise. For each single index and comprehensive index, we use the method of statistical analysis and double tail paired T test. It is proved that the "IPO effect" does exist in the main board market of our country, and no matter whether the listed companies have venture capital background or which industry they are in, they all present different degrees of IPO effect. We use univariate variance F test and univariate multivariate variance test F test to study the sample groups of different venture capital background and different industries respectively. The results show that after IPO, only the ability to repay debt has improved significantly. In addition, both before IPO and after IPO, the operating performance of the listed companies with background of venture capital is better than that of the listed companies without background of venture capital, and after IPO, the performance of listed companies with venture capital background is better than that of listed companies without background of venture capital. The asset liability ratio and current ratio of listed companies with venture capital background are significantly better than those without venture capital background. From the industry point of view, different industries have a certain impact on the changes of business performance before and after IPO. Finally, we give some suggestions on how to reduce IPO effect.
