摘要
中国的股权激励正式实施已逾十年,相当数量的股权激励方案进入行权期,但是,已有研究大都关注股权激励方案设计、公告和授予阶段高管的机会主义行为,对股权激励正向效应的分析较少,且主要集中在股权激励带来的利益协同效应上,忽视了风险承担激励。本文分别用高管财富—股票价格敏感性(Delt a)和高管财富-股票收益波动率敏感性(Vega)来度量利益协同效应和风险承担效应,实证检验了股权激励与企业风险承担水平和政策选择之间的关系。研究结果表明,Vega与公司风险承担水平显著正相关,国有企业的这种风险承担效应没有民营企业表现得明显。在企业的政策选择方面,Vega提高了企业的经营集中度和资产负债率,但是并没有促进R&D投资。本文的研究证实了中国股票期权的激励效果,丰富和拓展了国内股权激励研究,对下一阶段的股权激励方案设计具有一定的指导意义。
