【摘要】:2014年6月20日證監(jiān)會發(fā)布《關(guān)于上市公司實施員工持股計劃試點的指導意見》,對員工持股計劃的實施方式作了詳細規(guī)定,同時也放開了多種限制,使上市公司推出員工持股計劃的運作更加豐富靈活,標志著新時期員工持股計劃的開始。雖然我國員工持股計劃的發(fā)展受到了不少經(jīng)濟學家的關(guān)注,但學術(shù)界對于員工持股計劃激勵效果的研究主要集中在員工持股計劃對企業(yè)長短期績效的影響。由于早些年數(shù)據(jù)披露問題以及數(shù)據(jù)樣本偏小,致使國內(nèi)少有學者從市場績效的角度對員工持股計劃進行解讀。本文以2014年6月至2016年7月底我國A股市場502家推出員工持股計劃的上市公司為基礎(chǔ)樣本,并按規(guī)則剔除不滿足觀察研究的公司,最后刷選出201家作為研究樣本。采用事件研究法,并根據(jù)市場模型計算樣本公司在不同時間窗口期的平均異常收益率和累積平均異常收益率,構(gòu)建零假設(shè)進行T檢驗,檢驗員工持股計劃事件的市場效應(yīng),同時從股票來源、資金來源、高管認購比例、杠桿比例等影響市場效應(yīng)的不同因素分組分析。研究發(fā)現(xiàn),我國員工持股計劃對企業(yè)的短期市場績效有顯著的正向影響,直觀數(shù)據(jù)顯示草案公布前1交易日至后5個交易日窗口期內(nèi)獲得6.1%的累積超額收益率。而影響因素方面,股票來源為非公開發(fā)行方式的持股計劃短期對市場有明顯的刺激效果,而二級市場購買型的在擴大考察窗口期后也有不錯的平均異常收益率;資金來源為融資借款形式的持股計劃相比員工自籌形式有更好的市場表現(xiàn),在[0,20]期間累積平均異常收益率達到最高11.64%;高管持股比例越高越能獲得投資者對公司未來發(fā)展的認同;最后杠桿比例大小體現(xiàn)了大股東承擔劣后端風險的程度,其比例越高市場效應(yīng)更顯著;谝陨系膶嵶C研究成果,本文分別構(gòu)建兩種投資策略:非公開發(fā)行型投資策略和二級市場購買型投資策略,并通過樣本外的數(shù)據(jù)驗證取得不錯的收益,為廣大投資者提供對事件投資的科學理性研究思路。
[Abstract]:In June 20th 2014, the Securities Regulatory Commission issued the guidance on the implementation of the ESOP pilot in listed companies, which made detailed regulations on the implementation of ESOP, and at the same time released a variety of restrictions. The introduction of ESOP by listed companies has become more flexible and rich, marking the beginning of ESOP in the new era. Although the development of ESOP in China has attracted the attention of many economists, However, the academic research on the incentive effect of ESOP mainly focuses on the impact of ESOP on the long-term and short-term performance of enterprises. As a result, few domestic scholars interpret the ESOP from the perspective of market performance. This paper takes 502 listed companies in the A-share market from June 2014 to July 2016 as the basic samples. According to the rules, the companies that were not satisfied with the observation research were eliminated, and 201 companies were selected as the research samples. The method of event research was adopted. According to the market model, the average abnormal rate of return and cumulative average abnormal rate of return of the sample company in different time window period are calculated, and the zero hypothesis is constructed to test the market effect of the ESOP event, and at the same time, from the stock source. The analysis of different factors influencing the market effect, such as the source of funds, the proportion of senior executives' subscription, the proportion of leverage, etc. The study found that the ESOP has a significant positive impact on the short-term market performance of enterprises. Intuitionistic data show that the draft has obtained a cumulative excess return of 6.1% in the window period from the first trading day to the next five trading days. In terms of influencing factors, the stock holding plan, which comes from the non-public issuance mode, has a significant short-term stimulus effect on the market. In the secondary market, there is also a good average abnormal rate of return after the expansion of the window period. The shareholding plan, which comes from the form of financing and borrowing, has better market performance than the employee self-financing form. The cumulative average abnormal rate of return reached the highest 11.64% during the period of [20]; the higher the proportion of executive shares, the more investors recognized the future development of the company; and the extent of the final leverage ratio reflected the extent to which large shareholders took on bad back-end risks. Based on the above empirical research results, this paper constructs two investment strategies: the non-public issuance investment strategy and the secondary market purchase investment strategy. And through the data verification outside the sample to obtain the good income, provides the scientific rational research thought to the event investment for the vast number of investors.
