粤港澳大湾区中心城市经济辐射影响因素的异质性分析

Heterogeneity Analysis of Influencing Factors about Economic Radiation of Central Cities of Guangdong-Hong Kong-Macao Greater Bay Area

粤港澳大湾区在辐射带动周边地区加快发展方面具有重要作用。本文综合运用灰色关联模型和面板回归模型探讨了粤港澳大湾区中心城市经济辐射影响因素的异质性。研究表明:第一,相比信息通讯技术,交通基础设施、人力资本和金融资本对粤港澳大湾区经济辐射强度具有更为显著的正向影响。第二,这些因素对经济辐射强度的影响因市而异。其中,交通基础设施对广州的经济辐射强度影响最大,人力资本对深圳的经济辐射强度影响最大,金融资本对香港的经济辐射强度影响最大。

The Guangdong-Hong Kong-Macao Greater Bay Area(GBA)is very important to radiate and accelerate the development of surrounding areas.The gray correlation model and the panel regression model are used to explore the driving mechanism of economic radiation.Studies have shown that:First,compared with informa⁃tion and communication technology,transportation infrastructure,human capital and financial capital have a more significant positive impact on the economic radiation intensity of the Guangdong-Hong Kong-Macao Greater Bay Area.Second,the influence of these factors on the intensity of economic radiation varies from city to city.Among them,transportation infrastructure has the greatest impact on Guangzhou’s economic radi⁃ation intensity,human capital has the greatest impact on Shenzhen’s economic radiation intensity,and fi⁃nancial capital has the greatest impact on Hong Kong’s economic radiation intensity.
