摘　　要：基于数字化基础设施、数字产业发展、数字化创新、数字经济环境四个维度,构建中国省域数字经济发展水平综合评价指标体系,选取我国30个省(区市) 2014—2021年的数据,采用熵权法进行数字经济发展水平测度。在此基础上,借助Arcgi s10.8、Geoda1.2软件,通过莫兰指数、修正引力模型、标准差椭圆进行时空特征探析。研究发现:我国数字经济整体缓慢增长,区域差异大,由东部沿海向中西部阶梯式递减;各省域经济联系日益密切,数字要素流动性增强;空间上存在正相关性,主要呈低低集聚;空间分布方向上呈东北—西南,且经济重心向西南转移。A comprehensive evaluation index system for the development level of China's provincial digital economy was constructed based on four dimensions of digital infrastructure,digital industry development,digital innovation,and digital economic environment.The entropy weight method was used to measure the level of digital economic development with data selected from 30 provinces(autonomous regions and municipalities)in China from 2014 to 2021.Further more,spatio-temporal characteristics were analyzed through Moran's index,modified gravity model,and standard deviation ellipse by using Arcgis10.8 and Geoda1.2.It is found that the overall growth of China's digital economy is slow,with significant regional differences,gradually decreasing from the eastern coastal areas to the central and western regions,that the economic connections between the provinces are becoming increasingly close,and the mobility of digital factors is increasing,that there is a positive correlation in space,mainly exhibiting low-low agglomeration,and that the spatial distribution direction is from northeast to southwest and the economic center is shifting towards the southwest.
