数字经济对我国制造业竞争力影响研究——基于产业集聚的中介效应分析

The Impact of Digital Economy on Competitiveness of China's Manufacturing Industry:Analysis of Intermediary Effect Based on Industrial Agglomeration

在数字经济迅速发展的背景下,数字经济对我国制造业竞争力的提升有怎样的促进作用成为研究热点。本文根据我国2008—2017年省级面板数据分析数字经济提升制造业竞争力的作用效果,并从地区和产业类别角度分别分析作用效果的差异性,同时对产业集聚在此过程中的中介作用进行研究。研究结果表明,数字经济发展总体上能显著提升制造业竞争力,且作用效果呈倒“U”形趋势;分地区看,数字经济在东部地区对制造业竞争力的影响强于其他地区;分行业看,资本、技术密集型制造业更易受到数字经济的影响;产业集聚存在部分中介作用。基于上述结论,本文提出相应的对策建议:强化区域合作;有序推动不同密集度制造业的数字化进程;以产业集聚引领制造业不断进步。

In the context of rapid development of digital economy,how digital economy promotes the competitive-ness of China's manufacturing industry has become a research hot spot.Based on China's provincial panel data from 2008 to 2017,this paper first analyzes the effect of digital economy on improving the competitiveness of manufacturing industry,then analyzes the differences of effect from the perspective of region and industrial category,and finally studies the intermediary role of industrial agglomeration in this process.The results show that on the whole,the development of digital economy can significantly improve the competitiveness of manufacturing industry,and the effect shows an inverted"U"trend.In terms of region,the impact of digital economy on manufacturing competitiveness in the eastern region is stronger than that in other regions;while in terms of industries,capital and technology intensive manufacturing industries are more vulnerable to the impact of digital economy,and industrial agglomeration has some intermediary effects.Based on the above study,this paper puts forward corresponding countermeasures and suggestions:to strengthen regional cooperation,to promote digital process of manufacturing industry of different intensity in an orderly way,and to lead manufacturing industry to make continuous progress by industrial agglomeration.
