中部地区城市数字化与绿色化协同发展演化与驱动因素分析

数字化与绿色化协同发展是我国实现高质量发展的必然选择。在探析数字化与绿色化协同发展机理的基础上，基于2012-2021 年相关数据运用修正的耦合协调度模型测度我国中部地区80 个城市数字化与绿色化协同发展水平，运用核密度估计、空间自相关等方法定量分析其时空演化特征，并构建面板Tobit 模型识别驱动因素。结果显示：① 2012-2021 年我国中部地区数字化与绿色化耦合协调水平整体上有所提高，城市间差异有增大趋势；②中部地区城市耦合协调度存在空间正相关关系，集聚格局以“高- 高”和“低- 低”集聚为主；③产业结构合理化水平、科技创新水平和产业结构高级化水平是中部地区城市数字化与绿色化协同发展的核心驱动因素，对于资源型城市和非资源型城市具有异质性影响效应。基于此，提出促进区域数字化与绿色化协同发展的政策建议，助力经济高质量发展。

Research on the Evolutionary Characteristics and Infl uencing Factors of the Coordinated 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 modifi ed 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 diff erence 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 infl uence eff ects 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.
