数字物流对制造业集聚的影响研究

Impact of Digital Logistics on Manufacturing Agglomeration

本文基于2012—2022年中国31个省(区、市)的面板数据,分析数字物流对制造业集聚的影响及其机制。采用主成分分析法测度数字物流发展水平,采用区位熵法测度制造业集聚程度,并运用固定效应模型实证检验数字物流对制造业集聚的影响。研究表明:数字物流对制造业集聚有显著作用,其作用在东部地区和数字物流发展程度较高的地区更为明显;通过机制分析发现,劳动力集聚程度和劳动力创新能力是数字物流促进制造业集聚的重要因素,而劳动力自由流动则会抑制制造业集聚。因此,要加快深化数字物流与制造业的融合发展,同时要促进人力资本的良序发展以及立足数字物流地区异质性,推动地区协调发展。

Based on the panel data of 31 provinces in China from 2012 to 2022,this paper analyzes the impact of digital logistics on the development of manufacturing agglomeration and its mechanism effect.It adopts principal component analysis to measure digital logistics,uses location quotient to calculate manufacturing agglomeration,and empirically tests the impact of digital logistics on manufacturing agglomeration using the fixed-effects model.The study shows:digital logistics has a significant effect on manufacturing agglomeration,and the effect is more significant in the eastern region and the regions with higher degree of development of digital logistics;the mechanism analysis finds that the level of labor agglomeration and labor innovation ability are important paths for digital logistics to promote manufacturing agglomeration,while labor mobility is a path that inhibit manufacturing agglomeration.Therefore,this paper argues that it is necessary to deepen the integration of digital logistics and manufacturing industry,to promote the orderly development of human capital and to promote the coordinated development of the region based on the regional heterogeneity of digital logistics.
