摘要
利用2014—2022年上市公司数据,以2018年增值税留抵退税政策为准自然实验构建双重差分模型,实证探讨增值税留抵退税政策对企业绿色创新水平的影响及其内在机理,并进一步分析了该政策对企业绿色创新质量的作用。研究发现:第一,增值税留抵退税政策可以驱动企业绿色创新;第二,该政策作用于企业绿色创新的三个渠道是研发渠道、公司治理渠道和数字化转型渠道;第三,该政策不仅能够令绿色创新活动的数量在企业内实现有效增长,还能提高企业绿色创新质量,产生“量增质升”的效果。该研究为政府如何更有效地发挥税收政策对绿色创新的调节作用提供了新的启示。
Based on the data of listed companies from 2014 to 2022,a difference-in-difference model is constructed with the 2018 VAT refund policy as a quasi-natural experiment.The impact of the VAT refund policy on the level of green innovation of enterprises and its internal mechanism are empirically discussed,and the effect of the policy on the quality of green innovation of enterprises is further analyzed.There are three key findings.Firstly,the VAT refund policy can boost firms′level of green innovation.Secondly,the policy facilitates green innovation through channels like R&D,management,and digital transformation.Thirdly,not only does the VAT refund policy increase the quantity of green innovation,but it also enhances its quality,resulting in a"quantity-quality improvement"effect.This study provides new enlightenment for how the government can more effectively play the role of tax policy in regulating green innovation.
