摘　　要：城市环境规制刻画了地方政府在绿色创新中的角色特征。基于我国279个地级市面板数据,从知识作用视角,采用负二项分布模型测度我国城市环境规制强度的地区差异性对城市绿色创新质量的影响机制。研究发现:①邻近城市的高环境规制强度对本地绿色创新质量产生抑制作用,该抑制作用通过城市间知识宽度缩小、知识距离扩大两类中介效应影响本地绿色创新质量;②城市间的知识平衡度在邻近城市环境规制强度与本地绿色创新质量关系中发挥调节效应,当城市间知识平衡度较高时,邻近城市的高环境规制强度对本地绿色创新质量的影响由负转正。由此,获得如下政策启示:地方政府应重视环境规制政策带来的知识成分变化与知识结构调整,促进环境政策与绿色创新政策协同,同时,不同地方间应深化绿色创新主体合作机制,促进知识流动,提升城市绿色创新质量。Green innovation is an important method of decoupling economic growth from the perspective of environmental pollution.As global climate change,energy shortage and sustainable development issues are gaining increasing attention,so is the demand for such innovations.Green innovation covers green product innovation,green process innovation,cleaner production technology innovation,and pollutant end-of-pipe management innovation.Although various studies have not yet reached a unified definition of the concept of green innovation,most researches cover the two objectives of green innovation,i.e.,reducing natural resource dependence and reducing pollution emissions.In contrast to green innovation behavior,green innovation quality is innovation outcome-oriented,and technological complexity,economic efficiency,and technological impact are the main ways to measure green innovation quality.Environmental regulation policy is considered to be an important tool to promote green innovation against the"double market failure".In recent years,the central and local governments in China have paid more attention to environmental protection issues than ever.The amount of investment and financial expenditure in environmental protection have been increasing year by year,but the quantitative increase in China’s innovation has not been accompanied by a qualitative improvement.This phenomenon raises the question of how China's environmental regulatory affect the quality of green innovation.At present,environmental regulation in China is mainly decentralized,and the differences in the implementation of environmental regulation standards by local governments have led to inter-city heterogeneity in environmental regulation.As the central government pays more and more attention to environmental protection,the"bottom-up competition"among local governments is changing to an asymmetrical pattern of"bottom-up competition"and"race to the top".The heterogeneous regulation among cities directly affects the green innovation behavior of subjects withi
