摘　　要：我国经济发展面临着多方面挑战,要稳固社会经济增长,发挥数字产业的作用尤为重要。文章应用投入产出法,依据国家统计局《数字经济及其核心产业统计分类(2021)》中数字产业的分类标准,通过分离系数法从国家投入产出表中得到数字产业投入产出表,进而应用SDA模型从需求侧视角探究数字产业的经济增长效应,并对不同时期的经济增长效应进行动态比较,直观展示不同时期数字产业经济增长效应驱动力的差异性。结果显示:投资一直是数字产业和细分部门经济增长的主要推动力,居民消费、政府消费、出口扩张等驱动因素的推动力在各行业有所差别。China’s economic development faces multiple challenges.In order to stabilize social and economic growth,the role of the digital industry becomes particularly significant.This paper applies input-output method and accords to the classification standard of digital economy industries in the Statistical Classification of Digital Economy and Its Core Industries(2021)of the National Bureau of Statistics to obtain the input-output table of digital industry from the national input-output table through the separation coefficient method,and then applies the SDA model to explore the economic growth effect of digital industry from the perspective of demand side.The dynamic comparison of economic growth in different periods shows the difference of economic growth drivers of digital industry in different periods.The results show that investment has been the main driving force for the economic growth of digital industries and sub-sectors,and the driving force of household consumption,government consumption,export expansion and other drivers is different in various industries.
