摘要
本文以信息技术、电子与医药、生物制品三个行业上市公司为样本,以研发人员比重衡量企业技术创新投入,研究了我国相关税收优惠政策对企业技术创新的影响。结果表明,享受税收优惠政策的企业,研发人员比重显著高于其他企业。进一步地,本文还比较了不同税种、不同优惠工具激励效应的差异。我们发现流转税优惠的激励作用大于所得税优惠。在享受所得税优惠的样本中,税基优惠企业的研发人员比重高于税率优惠企业,但这一点在统计上并不显著。

The result shows that for companies with tax credit, proportion of R&D employees is significantly higher than others.
