制造业数字化投入影响出口国内增加值的分析

Analysis of Manufacturing Industry Digitalization Inputs Impacting Domestic Value Added in Exports

制造业数字化是新一轮工业革命的核心技术。本文基于2009—2018年的数据,利用投入产出法计算制造业14个核心行业的数字化投入,测度制造业数字化投入影响出口国内增加值的机制。实证表明,制造业整体数字化对出口国内增加值有正向促进作用,其中对劳动密集型行业出口国内增加值有抑制作用,对资本密集型和技术密集型行业出口国内增加值都有促进作用。最后从夯实制造业数字技术基础,充分发挥技术密集型行业带动作用与技术溢出效应和通过政策引导贸易规则建立等方面提出对策建议。

The main technology of the new industrial revolution is the digitization of the manufacturing sector.The input-output approach is used in the article to compute the digitalization inputs of 14 manufacturing industry key sectors based on data from 2009 to 2018 and to assess how these inputs aff ect the manufacturing sector’s export and domestic value added.The empirical data demonstrates that the digitization of the manufacturing sector as a whole contributes positively to export domestic value added,suppresses export domestic value added for labor-intensive industries,and contributes to export domestic value added for both capital-and technology-intensive industries.Last but not least,countermeasures are suggested for strengthening the basis of digital technology in the manufacturing sector,activating the propelling eff ect of technology-intensive industries,and directing the establishment of trade rules through policies.
