| 摘要: |
| 以2008—2018年沪深A股新能源上市企业为样本,从创新数量和创新质量两个层面探究税收优惠对新能源企业创新绩效的影响。研究发现:税收优惠对新能源企业创新绩效的促进作用主要体现在创新数量的增加,而非创新质量的提升;研发资金投入在税收优惠促进新能源企业提高创新绩效的过程中起到中介作用,而研发人力投入没有起到中介作用。进一步研究表明:税收优惠对非国有新能源企业创新数量的促进作用强于国有新能源企业;税收优惠对不同新能源行业的企业创新绩效的影响不同;较高的市场化程度和完善的法治环境有利于发挥税收优惠政策的创新激励作用。为提高新能源产业税收优惠政策的创新激励效果,建议以高质量创新为导向完善减税政策;注重引导企业增加研发资金与人力资本投入;结合企业产权性质、所属行业、制度环境等因素制定减税措施。 |

| Abstract: |
| Taking Chinese A-share new energy listed enterprises of 2008-2018 as a sample, this study analyzes the effect of tax incentives on innovation performance of new energy enterprises. It finds that tax incentives can promote the innovation quantity, but cannot promote the innovation quality of new energy enterprises. By using Bootstrap method, it is found that the R&D investment plays a mediating role, yet the R&D human capital investment does not play a mediating role in the impact of tax incentives on innovation performance of new energy enterprises. Further study finds that the incentive effect is greater on innovation quantity of non-state-owned enterprises than that of state-owned enterprises; policy effect varies across different new energy sectors; there is a stronger positive effect on innovation quantity for firms located in the area of higher level of marketization and rule of law. To improve the incentive effect of tax incentives of new energy industry, tax incentives should be primarily oriented towards high quality innovation, focus on stimulating firms R&D investment and R&D human capital investment, and be adjusted based on the characteristics of ownership, sectors and institutional context. |
