Research On The Level Of Industrial Linkage And Influencing Factors Between Guangxi Beibu Gulf Economic Zone And Guangdong-Hong Kong-Macao Greater Bay Area

Coordinated regional development is an important way to promote high-quality economic development.Strengthening the linkage between the Guangxi Beibu Gulf Economic Zone and the Guangdong-Hong Kong-Macao Greater Bay Area(hereinafter referred to as the "two bays" linkage)is of great significance for implementing the national regional coordinated development strategy and accelerating the integration of the Guangxi Beibu Gulf Economic Zone into the new development pattern.Based on regional cooperation theory,industry correlation theory,and input-output theory,this paper selects 15 cities in Guangxi Beibu Gulf Economic Zone and Guangdong-Hong Kong-Macao Greater Bay Area as research objects.From the perspective of input and output,the "industrial linkage strength coefficient" is used to measure the degree of industrial linkage between the 15 cities in the "two bays",and then QAP regression analysis is used to analyze the influencing factors of industrial linkage.The results show that the intensity of industrial linkage between the "two bays" shows an increasing trend,and industrial cooperation still needs to be further strengthened;the industrial linkage space is quite different,Nanning and Yulin have the strongest industrial linkage with the Guangdong-Hong Kong-Macao Greater Bay Area,Beihai City has a moderate industrial linkage with the Guangdong-Hong Kong-Macao Greater Bay Area,and Fangchenggang,Qinzhou,and Chongzuo have the weakest industrial linkage with the Guangdong-Hong Kong-Macao Greater Bay Area;There are also differences in industry structure.Nanning and the Guangdong-Hong Kong-Macao Greater Bay Area are closely related in manufacturing,finance,electricity,heat,gas and water production and supply,transportation,warehousing and postal services,leasing and business services.Yulin City and the Guangdong-Hong Kong-Macao Greater Bay Area are closely related in manufacturing,financial and other industries.Beihai City,Qinzhou City,Fangchenggang City,Chongzuo City and the Guangdong-Hong Kong-Macao Greater Bay Area are closely related in manufacturing and other industries.Further empirical analysis shows that the industrial structure,opening to the outside world and investment level have a significant positive effect on the industrial linkage of the "two bays",while the spatial distance and financial expenditure have an inhibitory effect.Finally,put forward countermeasures and suggestions,which should optimize and upgrade the industrial structure,enhance the level of open cooperation,enhance the attractiveness of investment,and further improve the level of industrial linkage.
