数字经济的规模不断扩大，在宏观经济中的权重逐渐增大，对经济增长的引领作用明显。数字产业化和产业数字化是数字经济发展的重要组成部分，两者是相互联系、密不可分的。但从发展现实看，产业数字化是数字经济的主要贡献者，数字产业化的贡献显著低于产业数字化。在数字经济时代，数字产业化和产业数字化协同发展是数字经济高质量发展的基石。因此，以数字产业化和产业数字化协同发展为切入点，探究数字经济时代新的区域发展差距和区域新格局的演变是非常必要的。

本文基于数字经济内涵和已有研究成果，从协同视角出发，选取相关指标构建中国数字产业化和产业数字化协同发展指标体系，运用耦合协调度模型测度各省份数字产业化和产业数字化协同发展水平，并运用Dagum基尼系数、Kernel核密度估计等方法进一步对协同发展水平的区域差异和演进态势进行分析，最后借助障碍度模型进行障碍因素判断。研究发现：第一，中国数字产业化和产业数字化协同发展水平逐年递增，但整体仍处于中度耦合阶段。数字产业化显著滞后于产业数字化发展，提升数字产业化发展水平是提高协同水平的关键。第二，数字产业化和产业数字化协同发展水平的区域差异化显著。中国数字产业化和产业数字化协同发展的空间非均衡性显著但逐渐减弱。东部—中部、东部—西部及中部—西部的区域间数字产业化和产业数字化协同发展的差距显著大于东部—东北、中部—东北和西部—东北地区。中国数字产业化和产业数字化协同发展的区域间差异仍旧是东部—中部、东部—西部和中部—西部所拉动，总体差异仍将由区域间差异主导。第三，从障碍度诊断结果看，数字产业化的主要障碍因素集中在互联网行业和软件业，产业数字化的主要障碍因素体现在工业数字化中。但各省份的主要障碍因素存在明显差异。因此，本文认为当前数字经济发展阶段，提升数字产业化水平是促进数字产业化和产业数字化协同发展的关键，同时坚持产业数字化道路，提升数字技术应用率，省份间注重数字经济合作发展。

The scale of the digital economy is expanding, and its weight in the macro-economy is gradually increasing, which plays a significant role in guiding economic growth. Digital industrialization and industrial digitalization are important components of the development of digital economy, and they are interrelated and inseparable. However, from the perspective of development reality, industrial digitalization is the main contributor to the digital economy, and the contribution of digital industrialization is significantly lower than that of industrial digitalization. In the era of digital economy, the coordinated development of digital industrialization and industrial digitalization is the cornerstone of high-quality development of digital economy. Therefore, it is very necessary to explore the new regional development gap and the evolution of the new regional pattern in the digital economy era, taking the coordinated development of digital industrialization and industrial digitalization as the starting point.

Based on the connotation of digital economy and existing research results, this paper selects relevant indicators to build an indicator system for the coordinated development of China's digital industrialization and industrial digitalization from the perspective of synergy, uses the coupling coordination model to measure the level of coordinated development of digital industrialization and industrial digitalization in each province, and uses Dagum Gini coefficient, Kernel density estimation, spatial autocorrelation to further analyze the regional differences and evolution trend of the level of coordinated development, and finally the influencing factors are judged with the help of the obstacle degree model. The research finds that: first, the coordinated development level of China's digital industrialization and industrial digitalization is increasing year by year, but the overall level is still in the middle coupling stage. Digital industrialization lags significantly behind the development of industrial digitalization, and improving the development level of digital industrialization is the key to improving the level of collaboration. Second, the regional differentiation of the coordinated development level of digital industrialization and industrial digitalization is significant. The spatial imbalance of the coordinated development of China's digital industrialization and industrial digitalization is significant but gradually weakened. The gap between the coordinated development of digital industrialization and industry digitization in the eastern central, eastern western and central western regions is significantly greater than that in the eastern northeast, central northeast and western northeast regions. The regional differences in the coordinated development of China's digital industrialization and industrial digitalization are still driven by the eastern central, eastern western and central western regions, and the overall differences will still be dominated by regional differences. Third, from the results of obstacle diagnosis, the main obstacles to digital industrialization are concentrated in the internet industries and software, and the main obstacles to industrial digitization are reflected in industrial digitization. However, there are significant differences in the main obstacle factors among provinces.

Therefore, at the current stage of the development of the digital economy, improving the level of digital industrialization is the key to promoting the collaborative development of digital industrialization and industrial digitization. And we should adhere to the path of industrial digitization, improve the application rate of digital technology, and pay attention to the cooperative development of digital economy among provinces.
