摘　　要：为探讨在数字经济时代背景下,作为中国环境规制政策体系中极富特色的地方环境目标约束将如何驱动企业绿色创新质量提升?文章利用2011—2018年中国上市公司专利申请信息与专利被引数据,并根据历年各地市《政府工作报告》,实证检验不同类型地方环境目标约束强度对企业绿色创新质量的影响机制,以及数字经济在二者之间发挥的调节效应。研究发现:(1)以具体污染物减排为核心的直接环境目标约束强度提升对企业绿色创新质量存在负向影响,且数字经济在二者之间并不存在显著的调节作用;(2)尽管由于企业预期净收益下降,间接环境目标约束强度对企业绿色创新质量的正向影响呈边际递减规律,致使间接环境目标约束强度与企业绿色创新质量呈倒“U”型曲线关系,但当前间接环境目标约束强度对企业绿色创新质量的影响仍以促进为主;(3)数字经济在间接环境目标约束强度与企业绿色创新质量之间存在显著的正向调节效应,数字经济促使二者之间的倒“U”型关系曲线更加陡峭,也进一步提前了倒“U”型关系曲线“顶点”临界值的到来;(4)进一步分析发现,低碳转型政策的实施,特别是碳排放权交易机制,将有效缓解直接环境目标约束强度对企业绿色创新质量的负向影响,扩大间接环境目标约束强度的正向影响与数字经济的正向调节作用。因此,地方政府应健全完善以间接环境约束目标为主,直接环境约束目标为辅的环境目标约束体系制度,重视考核间接环境目标的具体完成情况并在下一年《政府工作报告》中公开报告,结合当地环境目标约束制定更灵活的创新“提质”激励政策机制,健全完善市场型环境规制手段及其应用,借助数字信息化技术加强精细化环境监管,深化数字经济与企业绿色科研的互动融合。To explore how local environmental target constraints,featured in China’s environmental regulation policy system,drive the improvement of enterprise green innovation quality under the background of the digital economy,this article conducted an empirical study on the impact mechanism of different types of local environmental target constraint intensity on the green innovation quality of enterprises and the moderating effect of the digital economy between local environmental target constraint intensity and enterprise green innovation quality based on the patent application information and patent citation data of listed companies in China from 2011 to 2018and various local versions of the Report on the Work of the Government over the years.The results showed that:(1) The improvement of the direct environmental target constraint intensity with specific pollutant emission reduction as the core had a negative impact on the green innovation quality of enterprises,and the digital economy did not have a significant moderating effect between direct environmental target constraint intensity and enterprise green innovation quality.(2) The positive impact of indirect environmental target constraint intensity on the green innovation quality of enterprises showed a marginal diminishing law due to the declining expected net income,resulting in an inverted ‘U’-type curve relationship between the indirect environmental target constraint intensity and the enterprise green innovation quality.However,the impact of indirect environmental target constraint intensity on the quality of green innovation was mainly facilitative.(3) There was a significant positive moderating effect of the digital economy on the relationship between indirect environmental target constraint intensity and the green innovation quality of enterprises.The digital economy caused a steeper inverted‘U’ relationship curve between them,which further promoted the early arrival of critical value of inverted ‘U’-shaped relationship curve vertex.(4) Further
