投入数字化与制造业全球价值链攀升:基于世界投入产出数据的全球检验

Input Digitization and Climbing Global Value Chain in Manufacturing:A Global Test Based on World Input-output Data

本文基于世界投入产出数据测算制造业投入数字化水平,实证检验了投入数字化对制造业全球价值链分工地位的影响。研究结果显示:投入数字化对制造业全球价值链分工地位提升有显著的正向影响,并主要通过数字交易投入及数字基础设施投入发挥作用;投入数字化对发展中国家制造业全球价值链位置攀升的作用大于发达国家;对技术密集型、资本密集型及劳动密集型制造业均具有正向影响。本文的研究为推进投入数字化、实现制造业向全球价值链高端跃进提供了经验证据与决策参考。

Based on the world input-output data,this paper calculates the input digitization level of manufacturing industry,and empirically tests the impact of input digitization on the status of division of labor in global value chain in manufacturing industry.The results show that input digitization has a significant positive impact on the promotion of the division of labor position of manufacturing global value chain,and mainly plays a role through digital transaction input and digital infrastructure input.At the same time,the impact of input digitization on the climbing position of global value chain in manufacturing in developing countries is greater than that in developed countries.And for technology-intensive,capital-intensive and labor-intensive manufacturing industries,the impact is positive to all three but weaken in the order.The conclusion of the research provides empirical evidence and decision-making reference for promoting the input digitization and realizing a high-end leap forward of the global value chain in manufacturing.
