中国数字经济与非数字经济的行业关联性研究

Digital Economy and Non-digital Economy Industry CorrelationResearch in China

随着数字技术的发展,数字经济已成为新一轮科技革命中的重要力量。基于2017年、2018年和2020年投入产出表相关数据,利用投入产出分解模型和社会网络分析法,研究数字经济和非数字经济的行业关联效应。研究结果表明:我国非数字经济行业推动与拉动作用更显著,且供给推动作用辐射更广;数字经济和非数字经济行业之间的内部效应最大,其次是溢出效应,反馈效应最小;我国核心部门依然以非数字经济部门为主,数字经济部门大多为边缘部门。应优化经济结构,推进产业数字化转型;做好行业规划,提升我国数字竞争力;完善相关政策,优化我国数字经济环境。

With the development of digital technology,digital economy has become the core element of a new round of scientific and technological revolution.Based on the relevant data of input-output table in 2017,2018 and 2020,the inputoutput decomposition model and social network analysis method are used to study the industry correlation effects of digital economy and non-digital economy.The results show that,firstly,the push and pull function of China’s non-digital economy industry is more significant,and the supply of push function radiation is wider.Furthermore,the internal effect between the digital economy and non-digital economy industries is the largest,followed by the spillover effect,and the feedback effect is the smallest.Finally,China’s core sectors are still dominated by non-digital economic sectors,and most of the digital economic sectors are marginal sectors.We should optimize the economic structure to promote the digital transformation of industry,carry out industry planning to increase China’s digital competitiveness and improve relevant policies to optimize the digital economic environment of our country.
