增值税改革对江苏先进制造业创新行为的激励效应

On the Incentive Effect of VAT Reform on Innovation Behavior of Jiangsu Advanced Manufacturing Industry

税收政策是调整产业结构和推动工业科技现代化发展的重要抓手,增值税改革有助于产业转型升级和科技现代化建设,发挥税收政策对宏观经济的调控作用。在理论分析的基础上,构建双重差分模型,利用2014—2019年江苏省先进制造业企业数据,以2016“营改增”全面落地及后续税率简并为制度背景,检验增值税改革对江苏省先进制造业创新行为的激励效应。研究发现:2016年增值税改革政策对先进制造行业的研发投入和创新产出产生显著的促进作用,但对研发投入的促进作用存在一定滞后激励效应。研究有助于深化认识增值税改革的微观影响机制,识别该政策发挥的具体经济后果,为更好地利用税收政策促进地方先进制造业转型升级提供经验支持。

Tax policy is an important way to adjust the industrial structure and promote the development of industrial science and technology modernization.The reform of value-added tax(VAT)is conducive to the transformation and upgrading of industry and the modernization of science and technology,and plays a regulatory role of tax policy on the macro-economy.Based on theoretical analysis,this paper constructs a DID model,and uses the data of advanced manufacturing enterprises in Jiangsu Province from 2014 to 2019 to test the incentive effect of VAT reform on the innovation behavior of advanced manufacturing industry in Jiangsu Province under the background of the full implementation of“replacing business tax with value-added tax”in 2016 and the subsequent change of VAT rate.It is found that the VAT reform policy in 2016 significantly promote the R&D investment and innovation output of advanced manufacturing industry,but R&D investment has a lag incentive effect.This study helps to deepen the understanding of the micro impact mechanism of VAT reform,identify the specific economic consequences of the policy,and provide experience support for the better use of tax policy to promote the transformation and upgrading of local advanced manufacturing industry.
