Spatial Clustering Research On Production Service Industry In Guangzhou-Foshan Metropolitan Area

With the rapid development of China's economy since the 21 st century,the structural adjustment of China's secondary and tertiary industries has accelerated,and the proportion of services in the total economy has increased.Among them,the financial industry,information transmission,computer services and software industry,The development of high-end production services represented by scientific and technological services and rental business services is particularly prominent.The production service industry of the Guangzhou-Foshan metropolis reflects the urban cluster cluster structure of the urban clusters combined with the industrial environment,and the small-scale urban districts support the development,integration and clustering.The Guangzhou-Foshan metropolis basically realized the transition and upgrading from the production factor-constrained to the industrial-optimized industrial transfer.The productive service industry has become the backbone of optimizing the urban industrial structure and the focus of enhancing the metropolitan industry's spatial competitiveness in the world.Therefore,this paper chooses to study the clustering phenomenon of the productive service industry in the metropolitan area,and has important theoretical and practical significance for improving the status of Guangzhou-Foshan City in the world city under the trend of global economic integration.This paper is divided into three parts.The first part is to explain the background meaning of the topic,the problem and the related research framework,and to review the literature on the development of the producer service industry.On this basis,the paper proposes the world city system and new industry.Research on the clustering of business buildings and the measurement of the concentration of productive services in the space horizon.The second part uses the business building data of the important space carrier of the productive service industry in the city to study the distribution and clustering of the productive service industry in the metropolitan area of Guangzhou-Foshan metropolitan area,and the current situation of the gathering of commercial buildings in the metropolitan area of Guangzhou-Foshan And the characteristics of the analysis of its spatial coupling relationship with the city(Chapter 4),then,focus on the analysis of the coupling factors of the industrial service industry space andbusiness building data clustering in the Guangzhou-Foshan metropolitan area(Chapter 5).In the third part of the urban spatial structure,the mechanism of clustering of production services in Guangzhou-Foshan and the construction of ecological circle in urban space is proposed,and the related ecosystem layers are reconstructed and darned from top to bottom.The necessity of policy.The main conclusions of cluster analysis are: the aggregation of production service industry is mainly concentrated in the urban CBD space,and the clustering can be divided into CAZ-CBD-Sub-CBD circle structure;the coupling study of space carrier commercial buildings and urban space diffusion development shows : The negative effect of the internal power and external mechanism of the producer service industry in the market environment on the positive effect of the agglomeration of the productive service industry in the metropolitan area of Guangzhou-Foshan and the construction of the ecological circle;the government policy measures for the urban CAZ space super giant nuclear space gathering trend It is positively related to the information transmission,computer service and software industry,and scientific and technological service agglomeration.However,for the urban ecosystem,the policy-regulating market measures have a significant negative correlation effect on space leasing and business service industry agglomeration,facilitating productive services.The construction of the ecosystem layer.
