以沪深A股重污染企业2010—2021的面板数据为样本,通过建立个体固定效应模型,研究减税激励对企业绿色技术创新的影响机理。研究发现:第一,减税激励对重污染企业绿色技术创新具有显著正向影响;第二,股权激励能够显著正向调节减税激励对企业绿色技术创新的影响作用;第三,研发投入在减税激励与重污染企业绿色技术创新的关系中扮演部分中介的角色。进一步研究发现,相对于小规模企业,减税激励对于大规模企业的绿色技术创新促进作用更为明显;相对于西部地区,减税激励对于东部和中部企业的绿色技术创新促进作用更为明显。建议健全宏观减税激励机制,并针对不同规模和地区的企业实施针对性减税激励举措,加大企业研发投入,再辅以企业的微观股权激励机制,最终促进重污染企业的绿色技术创新。

Based on the panel data of heavily polluting A-share Enterprises in Shanghai and Shenzhenfrom 2010 to 2021, this paper studied the mechanism of the impact of tax reduction incentives on greentechnology innovation by establishing an individual fixed effect model. The results indicate that firstly,tax reduction incentives have a significant positive impact on the green technology innovation of heavilypolluting enterprises; secondly, equity incentives can significantly positively regulate the impact of taxreduction incentives on the green technology innovation of enterprises; thirdly, R&D investment playsan intermediary role in the relationship between tax reduction incentives and green technology innovation of heavily polluting enterprises. Further research found that compared with small scale enterprises,tax reduction incentives for large scale enterprises play a much more obvious role in promoting greentechnology innovation; compared with the western region, the impact of tax reduction incentives for theeastern and central enterprises to promote the role of green technology innovation is much more obvious. It is suggested that the macro-incentive mechanism for tax reduction should be improved, and targeted tax reduction incentives should be implemented for enterprises of different sizes and regions, andR&D investment of enterprises should be increased, supplemented by micro-equity incentive mechanism of enterprises, finally, promote the green technology innovation of heavily polluting enterprises.
