研发费用加计扣除政策对上市制造企业绿色创新绩效的影响--基于双重差分法的实证检验

On the Influence of the Additional Deduction for R&D Expense Policy on the Green Innovation Performance of Listed Manufacturing Enterprises--An Empirical Study Based on Difference-in-Differences Method

以2016年新实施的研发费用加计扣除政策作为自然实验,构建双重差分模型,考察该政策对上市制造企业绿色创新的影响状况。研究发现,加计扣除政策能显著促进企业的绿色创新,进一步异质性检验表明:政策对非国有制造企业、高污染高能耗制造企业绿色创新的影响程度更高。研究结论为进一步完善相关政策,提高政策的实施精准度,保障政策红利落地提供了经验数据,有利于推动制造企业加大绿色创新投入,实现高质量发展。

Taking the newly implemented additional deduction policy on R&D expense in 2016 as a“natural experiment”,a difference-in-differences model is constructed to investigate the influence of this policy on the green innovation performance of listed manufacturing enterprises.It is found that the policy can significantly promote the green innovation of enterprises,and a further heterogeneity test shows that its influence on non-state-owned manufacturing enterprises and manufacturing enterprises with high pollution and energy consumption is greater.The research conclusion provides empirical data for further improving relevant policies and better implementation accuracy of them and ensuring the realization of dividend from government policy,which is conducive to promoting manufacturing enterprises to increase investment in green innovation and achieve high-quality development.
