The Coupling and Coordination Between Digital Economy and Green Economy: Evidence from China

Abstract

ABSTRACT This paper tries to empirically calculate the coupling and coordinate degree between digital economy and green economy by utilizing the data for 28 Chinese provinces from 2015 to 2020 via coupling coordination model. Specifically, we measure the development level of digital economy and green economy by utilizing the entropy weight method, which supports that while the digital economy and green economy increases quickly among all sample provinces, there exists problem of digital divide among different regions and the speed of digital economy is higher than that of green economy. Additionally, we calculated the degree of coupling and coordination between digital economy and green economy, which suggests that coordination and coupling between digital economy and green economy experiences sharp increase. Finally, we also investigated the regional heterogeneity for the coupling and coordination between such two factors and offered that while the absolute level of coupling and coordination between digital economy and green economy in western and eastern regions is lower than that in eastern regions, its growth rate is higher in western and eastern regions than that in eastern regions.
