| 摘 要： 为探讨数字经济时代的区域协调发展路径，测算了2016—2020年中国31个省的数字经济发展水平，以Kernel密度估计、Dagum基尼系数、Moranʹs I指数刻画其时空变化趋势；并借助空间计量模型讨论其收敛性与影响因素。从时空分布特征来看，近年来中国各省区数字经济发展水平不断提升，但存在明显梯度特征；绝对差距与相对差距演变趋势不一致，绝对差距呈扩大趋势，相对差距呈缩小趋势；经济发展水平、政府扶持力度、贸易开放程度，是数字经济发展的主要影响因素。从收敛性来看，中国数字经济发展水平存在显著的σ收敛和β收敛现象，并依托综合经济区形成了若干个数字经济发展俱乐部，区域创新能力对数字经济的收敛性产生了重要影响。 |

| Abstract: In order to explore the path of regional coordinated development in the digital economy era, this study estimated the development level of digital economy in 31 provinces of China from 2016 to 2020, described its spatio-temporal trend by using Kernel density estimation, Dagum Gini coefficient, and Moran's I index, and discussed the convergence and influencing factors with the help of spatial econometric model. From the perspective of spatial and temporal distribution characteristics, the development level of digital economy in China's provinces and regions has been continuously improved in recent years, but there is an obvious gradient as follows. First, the evolution trend of absolute gap and relative gap is not consistent, the absolute gap is expanding, and the relative gap is narrowing. Second, the level of economic development, government support and trade openness are the main factors in affecting the development of digital economy. From the perspective of convergence, the development level of China's digital economy has suggested significant σ convergence and β convergence, and has formed a number of digital economy development club based on the comprehensive economic zone. The regional innovation ability has exerted an important effect on the convergence of digital economy. |
