中国数字经济的产业关联和网络结构分析

Analysis of Industrial Linkage and Network Structure of China’s Digital Economy

“十四五”规划提出要加快建设数字经济,同时要提升产业链的现代化水平。基于2012年和2017年中国投入产出表,运用结构分解、社会网络分析和归因矩阵分析数字经济产业与其他产业的关联结构,结果表明:数字化赋权基础设施产业、数字化交易产业和数字化媒体产业在经济社会发展中的联系愈加紧密,其它产业需求增加能够显著促进三者的产出;前两个产业位于产业关联网络中较为中心的位置,而数字化媒体位于较边缘的位置;三个产业间彼此无法凝聚为一个子群,产业间的结构、模式、特点以及对其它产业的贡献有明显区别。该研究是对数字经济产业实证研究新视角的补充,刻画产业链结构图对认识数字经济产业在经济体系中位置,推动融合发展具有现实意义。

The“14th Five-Year Plan”proposes to speed up the construction of digital economy and upgrade the modernization level of industrial chain.Based the data of China’s 2012 and 2017 input-output table,this paper analyzes the linkage structure between the digital economy and other industries by using structural decomposition analysis,social network analysis and causative matrix method.The results show that the digital infrastructure industry,digital trading industry and digital media industry are more and more closely-linked in the economic and social development,and the increase in demand of other industries can significantly promote the output of these three digital economy industries.The first two industries are located at the center of China’s industrial linkage network,while the digital media industry is located at the edge of the network.The three industries of the digital economy cannot be condensed into a sub-group,and there are obvious differences in their structure,patterns,characteristics and contributions to other industries in the economy.This study is a supplement to the new perspective of empirical research on the digital economy industry.This study is of practical significance to depict the industrial chain structure chart and understand the position of digital economy industry in the economic system and promote the integrated development.
