数字经济驱动下粤港澳大湾区现代服务业与先进制造业的融合效应

Integration Effect Driven by the Digital Economy of Modern Services Industry and Advanced Manufacturing Industry in the Guangdong-Hong Kong-Macao Greater Bay Area

目前以粤港澳大湾区(以下简称“大湾区”)为研究对象,从数字经济视角分析现代服务业和先进制造业(以下简称“两业”)融合效应的研究较为缺乏。为此,立足于大湾区数字经济快速发展的重大机遇和我国“十四五”规划所倡导的推动深度融合的战略导向,在分析数字经济驱动两业深度融合的作用机制基础上,选取2011—2020年大湾区11个城市的面板数据,构建两业融合和数字经济发展评价指数,并使用多元线性回归模型和中介效应模型分析数字经济促进两业融合发展的路径机制。结果表明:数字经济对大湾区两业融合具有显著促进作用,但影响效应具有区域差异性,相比于港澳两地和中心城市,对珠三角地区和外围城市的两业融合的影响更大;扩大市场需求从而引发质量变革是数字经济驱动两业深度融合主要路径,起着提升两业产品与服务质量的作用。因此,粤港澳大湾区需要从实施动态化和差异化的数字经济发展策略、建立数字经济与产业融合协同发展机制以及加快推进数字经济效率变革、动力变革、质量变革的进程等方面促进两业深度融合发展。

At present,the lack of research about the Guangdong-Hong Kong-Macao Greater Bay Area(hereinafter referred to as the"Greater Bay Area")as the research object,analyzing the integration effect of modern service industry and advanced manufacturing industry(hereinafter referred to as"two industries")from the perspective of digital economy.To this end,grounded on the major opportunities of rapid development of digital economy in the Greater Bay Area and the strategic orientation of promoting deep integration advocated by China's 14th Five-Year Plan,based on the analysis of the mechanism of digital economy driving the deep integration of the two industries,selecting panel data from 11 cities in the Greater Bay Area from 2011 to 2020,this paper builds the evaluation index of the integration of the two industries and the digital economy development,and uses the multiple linear regression model and the intermediary effect model to analyze the path mechanism of digital economy to promote the integrated development of the two industries.The results show that the digital economy can significantly promote the integration of the two industries in the Greater Bay Area,but the influence effect has regional differences,while comparing with Hong Kong,Macao and central cities,the impact in the Pearl River Delta region and the peripheral cities is even greater;expanding the market demand and thus leading to the quality change is the main path of digital economy to drive the deep integration of the two industries,and plays a role in improving the quality of products and services of the two industries.Therefore,the Guangdong-Hong Kong-Macao Greater Bay Area needs to promote the deep integration of the two industries from the aspects of implementing dynamic and differentiated digital economy development strategies,establishing the coordinated development mechanism of digital economy and industry,and accelerating the process of efficiency,power and quality reform of the digital economy.
