摘　　要：利用2009—2018年中国上市公司数据,实证考察高新技术企业所得税税率优惠对企业自主创新的影响。研究发现,税率优惠对企业自主创新绩效有着正向促进作用,且税率优惠持续时间越长,对自主创新的激励效应也越强,但随着企业自主创新水平的提高,税率优惠的创新激励效应呈现递减趋势。异质性分析表明,税率优惠对企业自主创新绩效的促进作用主要集中于那些对税率优惠激励更敏感的企业以及创新投入资源相对不足的企业。机制分析发现,税率优惠主要通过促进企业加大财力、物力和人力三方面投入提升企业自主创新绩效。此外,对处于不同生命周期的企业而言,税率优惠的自主创新激励效应并不等同;税率优惠激励下的企业自主创新行为还促使其市场表现的提高,为企业持续创新提供了动力。This paper uses the data of listed companies in China from 2009 to 2018 to examine the impact of preferential corporate income tax rates for high-tech enterprises on corporate independent innovation.The study shows that preferential tax rate has a positive effect on the performance of independent innovation of enterprises,and the longer the preferential tax rate lasts,the stronger the incentive effect on independent innovation.However,with innovation improvement,the innovation incentive effect of preferential tax rates shows a decreasing trend.The promotion effect of preferential tax rate on the performance of independent innovation of enterprises is mainly concentrated on those enterprises that are more sensitive to tax incentives and those with relatively insufficient investment resources to invest in innovation.The preferential tax rate mainly promotes enterprises to increase investment in financial,material and human resources to improve their independent innovation performance.In addition,for companies in different life cycles,the incentive effect of preferential tax rates on independent innovation is not the same,and the independent innovation behavior of enterprises under the incentive of preferential tax rate has also promoted the improvement of their market performance and provided the ability for enterprises to continue to innovate.
