This study explores the logical relationship among the digital economy,dual environmental regulation,and green technology innovation,which are critical for the National Innovation Demonstration Zones(NIDZs)in achieving green and high-quality development.Using a sample of NIDZ companies with A-share listings in Shanghai and Shenzhen from 2011 to 2020,we empirically analyze the impact of the digital economy on enterprises'green technological innovation,including the conduction and threshold effects of dual environmental regulation.The results show that the digital economy has a significant promotional effect on green technology innovation by enterprises in the NIDZs,and this result varies significantly across different regions,industries,and enterprise levels in these zones.The digital economy promotes green technological innovation among enterprises in NIDZs through a dual environmental regulation transmission pathway.Further,according to the threshold effect test,with an increase in the intensity of dual environmental regulation,the impact of the digital economy on green technology innovation of NIDZ enterprises shows the threshold characteristic of"increasing marginal effect."Based on this,the NIDZs should focus on the top-level design of the development of the digital economy and give full play to its enabling effect on enterprises'green technological innovation in the NIDZs.
