【摘要】：上市公司的IPO市場表現(xiàn)一直是國內外學者研究的重點,尤其是上市首日IPO超額收益、長期表現(xiàn)以及其影響因素分析。近年來,隨著全球環(huán)境污染問題的逐漸突出,其引發(fā)的社會責任日益引起學者的關注。目前,關于社會責任對企業(yè)市場表現(xiàn)的影響主要形成了過度表現(xiàn)假說和表現(xiàn)不佳假說,但尚未形成統(tǒng)一的結論。礙于我國的綠色環(huán)保事業(yè)起步較晚,其對企業(yè)市場表現(xiàn)的影響研究較少,有關IPO市場表現(xiàn)的研究更是寥寥無幾,基于此,本文研究綠色環(huán)保企業(yè)的IPO市場表現(xiàn)問題。本文旨在研究綠色環(huán)保企業(yè)IPO上市后是否有"綠色溢價"問題,"綠色環(huán)保"是否能構成IPO市場表現(xiàn)的影響因素。本文以滬深A股市場2006-2015年期間所有新上市IPO為研究對象,根據(jù)國家環(huán)保局《2011年全國環(huán)境保護相關產業(yè)狀況公報》給出的定義對綠色環(huán)保企業(yè)進行界定,并采用節(jié)選配對的方法,選取了 245家綠色環(huán)保企業(yè)和245家非綠色環(huán)保企業(yè)作為樣本,運用描述性統(tǒng)計、傳統(tǒng)OLS回歸、分位數(shù)回歸等多種數(shù)理統(tǒng)計方法,對兩類樣本公司的IPO市場表現(xiàn)進行實證檢驗。在實證檢驗的過程中,首先將綠色環(huán)保企業(yè)與非綠色環(huán)保企業(yè)進行對比分析,其次引入"綠色"虛擬變量進行多元線性回歸,最后將單位產值排污費作為替代變量進行穩(wěn)健性檢驗,旨在得出綠色環(huán)保企業(yè)是否存在"綠色溢價"的結論。實證研究結果表明,就IPO抑價而言,綠色環(huán)保企業(yè)顯著低于非綠色環(huán)保企業(yè),而在IPO長期表現(xiàn)方面,兩者并無顯著差異,同時,環(huán)境績效并不能構成IPO市場表現(xiàn)的顯著影響因素。
[Abstract]:IPO market performance of listed companies has been the focus of scholars at home and abroad, especially on the first day of the listing of IPO excess returns, long-term performance and its impact factors analysis in recent years. With the global environmental pollution problem becoming more and more prominent, the social responsibility caused by it has attracted more and more attention of scholars. On the impact of social responsibility on corporate market performance has mainly formed a hypothesis of excessive performance and poor performance hypothesis, but has not yet reached a unified conclusion, due to the green environmental protection in China started late. Its impact on the market performance of enterprises is less research, IPO market performance research is very few, based on this. This paper studies the IPO market performance of green environmental protection enterprises. The purpose of this paper is to study whether there is a "green premium" for green environmental protection enterprises (IPO) after listing. Whether "green environmental protection" can constitute the influencing factors of IPO market performance. This paper studies all newly listed IPO in Shanghai and Shenzhen A-share market from 2006 to 2015. According to the definition given by the State Environmental Protection Bureau's "National Environmental Protection related Industry Bulletin of 2011", the green environmental protection enterprises are defined, and the method of excerpt matching is adopted. Selected 245 green environmental protection enterprises and 245 non-green environmental protection enterprises as samples, using descriptive statistics, traditional OLS regression, quantile regression and other mathematical statistical methods. The IPO market performance of the two types of sample companies is tested. In the process of empirical testing, the green environmental protection enterprises and non-green environmental protection enterprises are compared and analyzed. Secondly, the "green" virtual variable is introduced to carry on the multivariate linear regression, and finally, the unit output value sewage discharge fee is taken as the substitute variable to carry on the robustness test. The purpose of this paper is to draw the conclusion whether there is "green premium" in green environmental protection enterprises. The empirical results show that green environmental protection enterprises are significantly lower than non-green environmental protection enterprises in terms of IPO underpricing. In terms of long-term performance of IPO, there is no significant difference between the two. At the same time, environmental performance does not constitute a significant impact factor of IPO market performance.
