This paper calculates the green total factor productivity based on the data of 284 prefecture-level cities in Chi-na from 2011 to 2021,and empirically tests the effect of heterogeneous environmental regulation tools on green total factor productivity and the moderating effect of the digital economy between them.The empirical results show that the market-incentive environmental regulation will crowd out R&D and innovation funds in the short term and inhibit the green total factor productivity,and the"innovation compensation"effect will exceed the"compliance cost"effect in the long run,which is conducive to promoting the growth of green total factor productivity,that is,there is a"U"shaped relationship between them,and most provinces in China have not yet crossed the inflection point.In the short term,the command-and-control environmental regulation will force enterprises to carry out green technology innovation in a stressful manner,thereby promoting green total factor productivity,and in the long run,due to the difficulty of dynamic supervision and the squeeze on the productive resources of enterprises,it will inhibit green total factor productivity,and there is an inverted"U"shaped relationship between them.In the short term,public participatory environmental regulation will increase the environmental protection pressure of enterprises and the government and inhibit total factor productivity,and in the long run,with the strengthening of public awareness of environmental protection,it is conducive to promoting the growth of green total factor productivity,and there is a"U"shaped relationship between them.The moderating effect of the digital economy shows that the digital economy positively regulates the"U"shaped relationship between market incentive envi-ronmental regulation and green total factor productivity,negatively regulates the inverted"U"relationship between com-mand and control environmental regulation and green total factor productivity,and negatively regulates the"U"shaped relationship between public participation environmental regulation and green total factor productivity.
