从数字化基础水平、数字产业化、产业数字化3个维度构建了数字经济发展水平评价指标体系，并从东、中、西部三大区域及各维度考察2015—2023年中国数字经济发展水平，同时探讨了其时空演变特征。研究发现:第一，各省(自治区、直辖市)数字经济发展水平显著提升，根据特征可划分为领军地区、次领军地区、跟随地区、落后地区和一般地区。第二，从东、中、西部三大区域来看，总体呈现东、中、西梯度递减规律，其中，东部地区数字经济发展水平领先，中西部地区增速较快，空间集聚现象显著，尤其是中部地区。第三，从三大维度来看，各地数字化基础和产业数字化的空间集聚效应较强，且产业数字化水平差异较大。第四，中西部地区数字经济发展具有显著的空间集聚现象，数字化基础和产业数字化的空间集聚效应相对较强。

This paper establishes an evaluation index system for the development level of the digital economy,encompassing three dimensions: digital infrastructure,digital industrialization,and industrial digitization. It analyzes the development level of China's digital economy from 2015 to 2023 across the eastern,central,and western regions,as well as each dimension,and investigates its spatio-temporal evolution characteristics. The study reveals the following:( 1) Based on the development characteristics of the digital economy in various provinces( autonomous regions and municipalities directly under the central government),they can be categorized into five groups: leading areas,sub-leading areas,following areas,backward areas,and general areas.( 2) From the perspective of the three major regions( eastern,central,and western),an overall gradient decline from east to west is observed. The digital economy in the eastern region demonstrates leading development,while the growth rates in the central and western regions are faster,exhibiting significant spatial agglomeration,particularly in the central region.( 3) Across the three dimensions,the spatial agglomeration effect of digital infrastructure and industrial digitization is relatively strong,with notable variations in the level of industrial digitization.( 4) The development of the digital economy in the central and western regions shows a significant spatial agglomeration phenomenon,with a relatively robust spatial agglomeration effect of digital infrastructure and industrial digitization across all regions.
