摘　　要：关注中国碳排放权交易政策对企业绿色创新影响的异质性以及企业的绿色创新质量,以2013年中国碳排放权交易试点上线交易为关键时间点,基于2009—2019年A股上市企业绿色专利数据,运用三重差分法实证检验碳排放权交易政策对企业绿色创新的促进作用以及企业专利类型、规模和所在区域的异质性在其中的影响。结果表明:碳排放权交易试点政策对企业绿色创新有促进作用,能够促进企业发明型绿色专利数量和专利整体质量提升,且对东部地区企业绿色创新的促进效果优于中西部地区,对大规模企业的促进效果优于小型企业。因此,为促进企业尤其中小企业绿色创新和绿色转型,政府需要灵活运用碳交易市场等市场型环境规制工具,强化碳市场对创新质量的积极影响,并依据不同对象异质性特征灵活制定相关政策。This article focused on the heterogeneity impact of China’s emission trading policy on green innovation of enterprises and the quality of green innovation of enterprises,taking the launch of China’s carbon emission trading pilot markets in 2013 as the key time point.Based on the green patent data of A-share listed enterprises from 2009 to 2019,the triple difference model is used to empirically test the promotion effect of carbon emission trading policy on green innovation of enterprises and the influence of patent type,enterprises’scale and regional heterogeneities.The results show that:the pilot policy of carbon emission trading has a promoting effect on the green innovation of enterprises,and is able to improve the number of green patents for inventions and the overall quality of patents.Also,the promotion effect on the green innovation of enterprises in the eastern region is better than those in the eastern region,and the promotion effect of large enterprises is better than that of small enterprises.Therefore,in order to promote green innovation and achieve green transformation of enterprises,especially small and medium-sized enterprises,the government needs to flexibly use market-based environmental regulation tools such as carbon trading markets,strengthen the positive impact of carbon markets on innovation quality,and formulate relevant policies according to the heterogeneity of different objects.
