中文摘要:

      以我国2014年6月—2015年6月宣告员工持股计划的上市公司为样本,检验了上市公司公告员工持股计划对股东财富的影响,对不同股票来源和不同认购股票资金来源员工持股计划的股东财富效应进行了检验。研究发现,上市公司公告员工持股计划后,股东将获得正的累计超额收益率。公司通过定向增发新股方式实施员工持股计划的宣告效应要好于通过二级市场购买赠送给员工的宣告效应,无论股票来源是上述两种方式中的哪一种,其认购股票的资金来源为员工自有资金的宣告效应要好于通过其他资金来源认购员工持股的宣告效应。研究结论为证监会进一步完善相关法律、法规及我国上市公司更好地设计员工持股计划方案提供了一个新的经验。

英文摘要:

      Taking the samples of listed companies to announce the Employee Stock Option Plan (ESOP) during the period from June 2014 to June 2015 on China's stock market, this paper tests the impact of ESOP on shareholder's wealth and examines the ESOP shareholder's wealth effect from different capital sources and stock sources. The research indicates that after listed company announced their ESOP, the shareholders would obtain the positive Cumulative Abnormal Return (CAR). Moreover, as to the announcement effect of ESOP, the announcement effect of private placement as the way of stock sources is better than the announcement effect to buy from the secondary market as coupons to employees. No matter whether the stock source is private placement or the purchase on the secondary market, the announcement effect of employees' own fund as the way of capital source is better than the announcement effect of other sources of funding. Thus, this research can provide a new reference to ESOP system for China Securities Regulatory Commission (CSRC) to further perfect the “Guidance of Listed Company to Implement Pilot Employee Stock Option Plan” and help China's listed companies to design a better scheme of ESOP. 
