| As one of China’s important national city clusters,the rapid development of the PRD city cluster has played an important role in supporting and leading the growth of the national society and economy.However,the development characteristics of the PRD urban agglomerations have led to the phenomenon of uneven regional development in Guangdong Province,where the PRD urban agglomerations are located,which has seriously affected the further stable growth rate of the Guangdong economy.Among them,counties,as an effective link between the development strategy of urban agglomerations and the current rural revitalisation strategy,promote high-quality development of counties has become a breakthrough for the Guangdong government to achieve balanced regional development,while the examination of the spatial distribution and spatial effects of employment density can be an important perspective to understand the scale and efficiency of urban agglomerations.Based on this,this paper,based on relevant theories and empirical results at home and abroad,collates employment density data of 120 counties(cities)inside and outside the PRD urban agglomeration in Guangdong Province in 1995,2005 and 2015 from the perspective of spatial distribution of employment density,and uses the analysis methods of spatial statistics and spatial econometric models,combined with spatial Arcgis,Geoda and Stata,etc.The spatial analysis methods of spatial statistics and spatial econometric models,combined with spatial software such as Arcgis,Geoda and Stata,were used to study the evolution process and spatial effects of employment density in counties(cities)inside and outside the PRD city cluster.The main findings are as follows:First,the spatial distribution of employment density in counties(cities)inside and outside the PRD city cluster in Guangdong Province is extremely uneven,and the spatial structure of employment density manifests itself in a two-wing,two-tier structure led by Guangzhou and Shenzhen as the twin cores within the PRD city cluster,with Shantou in eastern Guangdong and Zhanjiang in western Guangdong.Secondly,the spatial clustering and spillover effects of employment density are found to be correlated,as shown by the fact that the spatial spillover effect is more obvious in areas with high employment density clusters,while there is no spatial spillover effect in contiguous low-value clusters of employment density.The spillover effect between counties(cities)is most pronounced within 10 km,mainly within the PRD urban agglomeration;the spillover effect gradually decreases within 20km-30 km,where some counties(cities)with low employment density outside the PRD urban agglomeration are found to be radiated by areas with high employment density within the urban agglomeration,but the degree of such radiation is relatively weak.Thirdly,the measurement results of the boundary model reveal that there is a strong spatial variability of employment density in counties(cities)inside and outside the PRD city cluster in Guangdong Province,and the regression coefficients characterise the strong boundary effect of the policy boundary of the PRD city cluster on the spatial distribution of employment density,and the spatial variability of employment density and the boundary effect of the PRD city cluster gradually increase in the time period of 1995,2005 and 2015.Finally,based on the above findings,policy recommendations for achieving a balanced development of regional employment within and outside the PRD urban agglomeration in Guangdong Province are provided in the following areas:Firstly,we should improve the carrying capacity of the county’s industrial transfer,increase the county’s employment opportunities and ability to absorb employment,and promote the employment of the labour force population in close proximity to the county,thus driving the regional balance of the regional employment layout.Secondly,we should promote the level of supply of public services in the county,provide quality public service resources,and increase investment in resource areas such as education,healthcare,culture and housing to provide a basis for the development of county industries,which in turn will form a circular effect.In addition optimise education resources to improve the quality of the workforce and increase the competitiveness of the employed themselves,thus enhancing the stability of regional employment.Finally,optimise the regional industrial layout and weaken the boundary barriers of the PRD city cluster. |
