Analysis On The Spatial Pattern Evolution And Network Structure Characteristics Of County Economy In The Former Central Soviet Area Of Jiangxi,Fujian And Guangdong

The Former Central Soviet Area of Jiangxi,Fujian and Guangdong is an important revolutionary base area which was created by the Communist Party of China during the period of Agrarian Revolution War,and it has a special role and important position in the history of Chinese revolution.However,due to the influence of war trauma,natural geography and other reasons,the economic development in the area has lagged significantly,and it has been in a state of unbalanced development for a long time.Under the background of the state’s strong support for the revitalization and development of the Soviet Area,the Former Central Soviet Area of Jiangxi,Fujian and Guangdong was selected as the study area.With the related theoretical knowledge of geography,economics,regional science and basic technical tools of GIS,RS,spatial and statistical analysis as the theoretical and technical support of this paper,and based on the nighttime light remote sensing data,socio-economic data and some other data,this paper explored the evolution law of the spatial pattern of county economy in the Former Central Soviet Area of Jiangxi,Fujian and Guangdong from the perspective of spatial pattern,and deeply explored the spatial connection network structure characteristics of county economic development in the Former Central Soviet Area of Jiangxi,Fujian and Guangdong from the perspective of network connection.It also quantitatively measured and qualitatively analyzed the reasons for the differences of county economic development in the Former Central Soviet Area of Jiangxi,Fujian and Guangdong from the perspective of influencing factors.Finally,according to the results of the empirical research,this paper put forward countermeasures and suggestions for the economic development of the Former Central Soviet Area of Jiangxi,Fujian and Guangdong,so as to provide decision support for promoting the economic revitalization and coordinated development of the Former Central Soviet Area of Jiangxi,Fujian and Guangdong.(1)From 2011 to 2020,the development of county economy has shown a trend of continuous improvement in the Former Central Soviet Area of Jiangxi,Fujian and Guangdong,but the spatial diversity characteristics of the county economy is still significant,with high levels in the south and low levels in the north,and the polarization phenomenon of economic growth is also obvious.The overall spatial connection of the region’s economy is weak,and there are areas of "contiguous poverty".The hot spot regions of economic development are mainly gathered in the southeast,the cold spot regions of economic development are mainly distributed in the west and north.The spatial and temporal evolution of cold spot regions and hot spot regions show relatively stable characteristics,and the regional economic development faces great challenges.(2)The intensity of economic connection among counties is generally low in the Former Central Soviet Area of Jiangxi,Fujian and Guangdong,and shows significant proximity effect and polarization effect.The overall spatial connection network has relative stability and strong accessibility,but its hierarchical structure is obvious.The counties mainly in southern Jiangxi region are located at the center of the spatial connection network and play a leading and controlling role in the whole economic connection network.However,the counties in northwestern Fujian and other regions are at the edge of the network and can only play the role of "marginal actors".The phenomenon of internal clusters is remarkable in the Former Central Soviet Area of Jiangxi,Fujian and Guangdong,and the spatial development pattern of "two core regions and six groups" has gradually formed.The eight subgroups have close internal connection,but there is little obvious spatial connection among different subgroups,and the connection among subgroups needs to be further strengthened.(3)Among the influencing factors of county economic development,economic strength,industrial structure,productivity level and road condition all play a significant positive contribution,and there are obvious regional differences in the impact of productivity level and road condition on the economic development of each county.
