From the perspective of the distance between the actual intensity and the inflection point strength of environmental regulations,this study interprets the formation mechanism of regional imbalances in China's green total factor productivity(GTFP).An empirical test is conducted based on provincial-level industrial sector data in China from 2001 to 2019.The results reveal a"U-shaped"relationship between the actual intensity of environmental regulations and GTFP.Due to the overall weak actual intensity of environmental regulation during the sample period,its impact on green total factor productivity is negative.However,as the actual intensity of environmental regulation surpasses the inflection point intensity at the end of the sample period,continued strict implementation of environmental regulation contributes to the enhancement of green total factor productivity.Owing to the strong technological innovation capabilities of enterprises and a higher level of industry structure greenization,the inflection point intensity of environmental regulation in the eastern region is relatively lower than that in the central and western regions.In the context of uneven implementation of environmental regulation policies in different regions in China,the eastern region exhibits relatively higher actual intensity of environmental regulation compared with the central and western regions,coupled with a lower inflection point intensity.This substantial distance between the actual intensity and inflection point intensity accentuates the pre-existing advantage of GTFP in the eastern region over the central and western regions,contributing to the escalating issue of regional imbalances in China's GTFP.
