摘要
选取2007—2019年中国上市公司的面板数据,从创新链视角探究税收优惠政策如何激励中国企业自主创新。研究发现,税收优惠政策对企业创新链的投入、产出以及效率环节均有显著激励作用。通过更换估计模型、构建工具变量等稳健性检验后,研究结论依然成立。异质性分析发现,税收优惠政策在创新投入端对非国企研发资金投入激励效果更强,对于国有企业研发人员投入以及企业创新链产出端激励效果更强;对于处于高技术行业的企业,税收优惠政策在企业创新链各个环节的激励作用都比非高技术行业企业更强。研究为企业创新决策、优化税收优惠政策增加了新的认知,为实施创新驱动发展战略提供了有益启示。
This paper evaluates the incentive effect of preferential tax policies on enterprise innovation from the perspective of innovation chain, using panel data of Chinese listed companies from 2007 to 2019.The study found that preferential tax policy has a significant incentive effect on the innovation input, output and efficiency of the innovation chain. After replacing the estimation model and constructing instrumental variables, the research conclusions are still robust. In the heterogeneity analysis, the preferential tax policy has a stronger incentive effect on R&D investment in non-state-owned enterprises, while it has a stronger incentive effect on R&D personnel and enterprise innovation output in state-owned enterprises. The incentive effect of preferential tax policy for enterprises in high-tech industries is stronger than that in non-high-tech industries. The research of this paper adds new cognition to the innovative decision-making and optimization of preferential tax policies in enterprises, and provides useful inspiration for the implementation of innovation-driven development strategy.
