Research on the Evolutionary Characteristics and Influencing Factors of the Coordinat-ed Development of Digitalization and Greening in the Central Region of China
The coordinated development of digitalization and greening is the inevitable choice for China to achieve high-quality development.Based on the analysis of the collaborative development mechanism of digitalization and greening,this paper measures the coordinated development level of digitalization and greening of 80 cities in the central region of China by using the modified coupling coordination model with the relevant data from 2012 to 2021,kernel density estimation and spatial autocorrelation are used to quantitative analysis the spatio-temporal evolution characteristics,and a panel Tobit model is constructed to identify the driving factors.The results show that:(1)From 2012 to 2021,the coordination level of digitalization and greening has been improved on the whole,and the difference between cities has an increasing trend;(2)There is a positive spatial correlation in the degree of coupling and coordination among cities,and the pattern of agglomeration is dominated by"high-high"and"low-low".(3)Industrial structure rationalization level,scientific and technological innovation level and industrial structure advanced level are the core driving factors for the coordinated development of digitalization and greening,and the influence effects have heterogeneity for resource-based cities and non-resource-based cities.Based on this,policy suggestions are put forward to promote the coordinated development of regional digitalization and greening to promote the high-quality economic development.
