摘　　要：数字经济是推动中国经济高质量发展的重要引擎,数字经济资本的积累能够优化产业结构、促进产业转型升级。本文运用永续盘存法和基年迭代法测度数字经济资本存量,运用基尼系数、核密度估计和莫兰指数分析数字经济资本存量的区位差异和演进趋势。研究发现:全国整体及30个省份数字经济资本存量均呈迅速增长态势,区域间数字经济资本存量分布表现出“东高西低”的特点;基尼系数分析结果表明,区域间差异是数字经济资本存量区位差异的主要原因;核密度估计结果显示,数字经济资本存量的省际分布存在区域集聚现象,分布不均衡程度加重;莫兰指数分析结果表明,大部分省份处于低水平区域并保持无跃迁的稳定状态。本文对于完善数字经济核算体系、推动数字经济产业融合与均衡发展具有重要意义。Digital economy is an important engine for driving high-quality economic development and is increasingly becoming an important driving force for building a modern economic system and a new development pattern.Its capital stock is the key foundation for the capital accumulation of digital industry and industrial transformation and upgrading.Existing research mainly focuses on the measurement of the scale and output of the digital economy,with less discussion on estimating the capital stock of the digital economy.There is also a lack of research on its spatial distribution structure,dynamic evolution trends,and long-term development trends.This paper first builds an accounting framework for capital stock of digital economy covering two dimensions of digital platforms and digital technology-based industries and five sub-industries based on the Industrial Classification of the National Economy,uses the data of fixed assets investment of various industries of the digital economy,introduces the parameters of digital economic structure,and calculates the annual investment amount and average service life of assets of the sub-industries based on the data of the economic census yearbook.Combining the perpetual inventory method with the base year iteration method,this paper measures the digital economy capital stock in the three major regions(eastern,western and central regions)of China,and 31 provincial-level regions from 2012 to 2019.This article also uses analysis tools such as Dagum Gini coefficient,Kernel density,and Moran index to study the location differences of digital economy capital stock and reveal its dynamic evolution law.Research results show that national and provincial digital capital stock shows a rapid growth trend,and the distribution of digital economic capital stock between provincial-level regions shows a characteristic of"high in the east and low in the west."The capital investment in the digital economy in the western region increases significantly and has a certain potential for latecomer developme
