摘　　要：文章从需求侧角度研究数字经济对国民经济的影响,在此基础上运用国家统计局发布的数字经济核心产业分类标准,构建了2017年、2020年数字经济核心产业可比价非竞争型投入产出表,采用“假设抽取”调整的Leonti-ef模型测算了需求拉动作用下数字经济核心产业的产出效应,进一步地运用结构分解方法对各产业部门的产出增长因素进行分析。结果表明:数字经济核心产业对国民经济有显著的需求拉动效应,且通过后向关联效应对上游产业具有一定的带动作用,其产出量的变化是引起国民经济其他部门产出增长的主要原因。因此,发展数字经济需要在加强数字经济与传统产业融合的同时,特别要重视数字经济核心产业从需求侧“赋能”所引发的产出效应,并充分发挥其在需求侧产出效应的优势。The article studies the impact of the digital economy on the national economy from the perspective of the demand side,constructs the comparable non-competitive input-output table of the core industries of the digital economy in 2017 and 2020 according to the classification standard of the core industries of the digital economy issued by the National Bureau of Statistics,and measures the demand-pull effect on the output of the core industries of the digital economy by using the"hypothetical extraction"adjusted Leontief model,and analyzes the factors of output growth of each industrial sector by using structural decomposition method.The results show that the core industries of the digital economy have a significant demand-pull effect on the national economy,and through the backward correlation effect they have a certain degree of dring effect on the upstream industries,and the change of their output is the main reason for the output growth of other sectors of the national economy.Therefore,the development of the digital economy necessitates not only strengthening its integration with traditional industries but also placing special emphasis on the output effect triggered by the"enablement"of the core industries of the digital economy from the demand side,and giving full play to the advantages of its output effect on the demand side.
