【摘要】 以2007-2016年中国战略性新兴产业A股上市公司数据为研究样本,从企业研发投入和专利产出两个维度,考察税收优惠政策与企业技术创新之间的关系。结果发现:①税收优惠政策对于企业自主创新具有激励作用,有效促进了企业研发投入和专利产出;②基于企业所属产业异质性视角发现,税收优惠政策对于八大战略性新兴产业企业的创新作用存在显著差异:对于新一代信息技术、高端装备制造业、节能环保等产业研发投入和专利产出具有激励作用,但对新能源产业的创新投入、生物产业和新能源汽车产业的专利产出具有抑制作用。研究结论在一定程度上解释了现有研究关于税收优惠政策"激励效应"和"抑制效应"的争议,也对完善中国创新税收激励制度具有借鉴意义。更多还原

【Abstract】 Based on the data of Chinese A-share listed companies of strategic emerging industries from 2007 to 2016, this paper analyzes the relationship between tax preference and the enterprise technology innovation from two dimensions involving enterprise R&D and patent output. We discover that the tax preference yields a positive effect on enterprise independent innovation and effectively promotes the R&D investment and patent output. Further study based on the industry to which the enterprise belongs finds that there are significant differences in the effect of tax preference on enterprise innovation in eight strategic emerging industries: it has an incentive effect on the R&D investment and patent output in the new generation of information technology, high-end equipment manufacturing, energy conservation and environmental protection, but it has a restraining effect on the innovation investment of the new energy industry and the patent output of the bio-industry and the new energy automobile industry. The conclusion of this paper explains the existing research about the "incentive effect" and "inhibition effect" of the preferential tax policy to some extent and has significance concerning policies in improving the innovation tax incentive system.更多还原
