税收优惠对企业创新效率的门槛效应——创新价值链视角下制造业的实证研究

Threshold Effects of Tax Incentives on Enterprise’s Innovation Efficiency——Empirical Research Based on Manufacturing Industry in Innovation Value Chain

摘要:

为研究税收优惠政策的实施效果,本文基于创新价值链视角,探究税收优惠对创新效率的作用机理,并分析行业环境因素对创新激励政策的调节效应。因此选用中国制造业2005-2015年行业面板数据构建SFA模型和门槛模型,实证结果表明：企业科技创新水平处于0.5~0.8范围内,整体发展不均衡、不协同。税收优惠在一定门槛范围内提升了企业创新效率,而在创新价值创造过程税收优惠则表现出门槛异质效益。同时,国有产权性质抑制科技研发阶段税收政策的实施效应而促进价值实现阶段；加强政产学研合作、出口鼓励政策,税收优惠政策更将显著激励企业创新。

Abstract:

In order to study the effect of tax incentives, this paper explores the mechanism of tax incentives on innovation efficiency from the perspective of the value chain. In addition, it analyzes the regulation of innovation incentives by industry environmental factors. Therefore, this paper selects China"s manufacturing industry panel data from 2005 to 2015 to construct SFA model and threshold effect model. The empirical results show that: The capabilities of corporate science and technology innovation are unbalanced and not coordinated within the range of 0.5 to 0.8. Tax incentives increase the efficiency of R D in a certain threshold. In the process of innovation value creation, tax incentives show a heterogeneous benefit. At the same time, State-owned property rights will inhibit the implementation of tax policies in the stage of technology research and development, but it will promote the stage of transformation of benefits. If the government can strengthen the industry-university-research collaboration and export encouragement policies, tax incentives will also significantly inspire corporate innovation.
