摘要：股权激励作为一种有效解决企业委托代理问题的长期激励机制，是在企业的所有权与经营权相分离后出现的。良好的股权激励机制能够起到实现人力资本价值，降低委托-代理成本等作用，有利于上市公司治理结构的不断完善,提高上市公司业绩。本文以2008-2009年实施股权激励的公司为依据，比较上市公司在实施股权激励前后两年的公司业绩，分析股权激励对公司业绩的影响，揭示对股权激励实施效果产生影响的因素。通过实证分析和理论分析，我们得出结论，成长性较高，竞争性较高，股权集中度较小，风险水平较高的企业实施股权激励的效果较好。公司应该提升产品的竞争性，规范高管人员的选择市场，根据公司自身的特性，选择适合自己的股权激励方案，进而有效的提高公司业绩。
