数字经济视角下生产性服务业集聚对制造业高质量发展的影响研究

Research on the Impact of Producer Service Industry Cluster on the High-quality Development of Manufacturing Industry from the View of Digital Economy

推进长三角地区制造业的高质量发展,是实现长三角一体化、加快经济发展的关键。在数字经济时代,信息技术在制造业中的传播和应用已经改变了生产性服务业影响制造业高质量发展的作用机制。本文构建长三角地区2011—2020年面板数据,采用双向固定效应模型和面板门槛效应模型,探讨长三角地区在数字化经济发展下,产业集聚对制造业高质量发展的影响。研究表明:(1)生产性服务业可以通过专业化和多样化集聚两种途径显著促进制造业高质量发展;(2)考虑数字经济的影响作用时,生产性服务业产业集聚在制造业高质量发展中表现出先强后弱的影响作用;(3)数字经济对生产性服务业的影响作用具有异质性,对高端生产性服务业集聚数字经济的推进作用表现显著,对低端生产性服务业专业化集聚推进作用不显著。因此,应进一步推动数字基础设施建设;通过人才引进等政策促进生产性服务业向高级化发展;促进数字经济和生产性服务业协调发展,优化制造业发展路径。

Promoting the development of high-quality manufacturing in the Yangtze River Delta region is the key to achieving Yangtze River Delta integration and accelerating economic development.In the era of the digital economy,the diffusion and application of information technology in manufacturing will change the role mechanism of the production services industry,affecting the high-quality development of the manufacturing industry.This white paper organizes panel data from 2011 to 2020 for the Yangtze River Delta region and uses a bidirectional fixed-effect model and a panel threshold effect model to examine the development of the Yangtze River Delta region in the development of the digital economy.The impact of industrial clusters on high-quality development of manufacturing.According to the study,(1)the service industry can contribute greatly to the transformation and modernization of manufacturing in two ways:specialization and diversification.(2)Given the impact of the digital economy,the cluster effect of the productive services industry represents a strong and low impact on the high-quality development of the manufacturing industry.(3)The impact of the digital economy on productive service industries is uneven,which has a significant impact on promoting the concentration of high-end service industries.Therefore,the construction of digital infrastructure should be further encouraged.Through policies such as recruitment,it will promote the modernization of productive service industries and the coordinated development of the economy.
