中文摘要：

本文以2006-2013年我国沪深A股上市公司的数据为样本,对税收优惠与企业技术创新的关系进行实证分析。结果发现税收优惠对企业研发投入具有显著激励效应,但对创新产出的激励作用则不明显。进一步研究发现,税收优惠对不同产权性质、不同地区和不同规模企业技术创新的影响存在较大差异,对民营企业、东部地区企业及大规模企业技术创新的激励作用更大。本文结论深化了对税收优惠与企业技术创新关系的认识,对进一步完善税收优惠政策、促进企业技术创新具有重要启示意义。

英文摘要：

This paper investigates the relationship between tax preference and technical innovation via the study on the sample of Chinese A-share listed companies （2006-2013）. The paper finds that tax preference stimulates corporate R＆D investment, but its impact on innovation output is insignificant. Moreover, a further analysis suggests that the incentive effects of tax preference on innovation are more significant in non-SOEs, firms with larger size or located in Eastern China by examining the heterogeneity of property nature, regions and firm size. Overall, the paper deepens the knowledge about the relationship between tax preference and technical innovation and has important enlightenment for improvement of the tax preference policies and innovation behavior.
