Spatio-temporal characteristics and driving mechanism of the coupling coordination between digital economy and green development in China
The mutual empowerment and coordination of digital economy and green development is an inherent requirement for high-quality development.On the basis of deconstructing the coupling coordination mechanism of digital economy and green development,this paper analyzes the spatio-temporal characteristics of the coupling coordination between digital economy and green development in China,as well as the driving mechanism of spatial differences from 2010 to 2019 by using the vertical and horizontal scatter degree method,coupling coordination degree model,and quadratic assignment procedure(QAP).The results show that:(1)In terms of temporal evolution,the coordination degree of China's digital economy and green development has experienced a process of"reluctant coordination-primary coordination-intermediate coordination"during the investigation period,but high-quality coordinated development is far from being achieved,and most provinces are in the primary coordination stage characterized by the lagging digital economy.(2)In terms of spatial change,the spatial differences of coordination are obvious,showing an overall pattern of"multi-core"radiation,a"concave"interregional pattern of"eastern leading,central collapsing,and western catching up",as well as an evolution pattern of coordination levels of"highly coordinated transformation in eastern China,and imbalanced separation in central and western China".(3)In terms of spatial correlation,the regional coordination has gradually changed from"polarization effect"to"diffusion effect",and the spatial characteristics have changed from agglomeration to equilibrium.(4)In terms of spatial differences and decomposition,regional differences are the main source of overall differences in coordination degree.(5)Analysis of driving mechanism shows that narrowing regional differences in digital economy is the fundamental driving force to promote the coupling and coordination of digital economy and green development,while the narrowing of external differences such as economic development,industrial structure and technological innovation fails to play a positive role.
