Study On Spatial Pattern And Optimization Integration Of China-Vietnam Cross-Border Economic Corridor

With the continuous development of economic globalization and the in-depth implementation of the “The belt and road”,cross border economic cooperation has become a hot spot of regional cooperation.China has put forward the vision of building six economic corridors,of which the China-South China Peninsula Economic Corridor is an important platform for cross-border economic cooperation for ASEAN countries.The cross-border economic corridor between China and Vietnam is the beginning of the China-South China Peninsula Economic Corridor,an important link between China and the South-East Peninsula,and an important gateway area for China's SouthOriented corridor.Therefore,the study of the current situation and future development strategies of cross-border economic corridors between China and Vietnam has important practical significance for guiding the construction of cross-border economic corridors between China and Vietnam,and further guiding the construction of China-South Peninsula Economic Corridor.In this paper,the cross-border economic corridor between China and Vietnam is taken as the research object,and the multi-dimensional interaction between production and city is taken as the research perspective to explore the spatial interaction pattern and optimization and integration of cross-border economic corridor.This paper makes an empirical analysis of the spatial pattern of cross-border economic corridors between China and Vietnam by using the methods of quantitative calculation of urban network theory and factor flow measurement of flow space theory.Firstly,on the basis of theoretical research,the paper puts forward four basic elements of cross-border economic corridor.Secondly,from the perspective of multi-dimensional interaction between industry and city,and taking the cross-border economic corridor between China and Vietnam as the research scope,this paper systematically analyzed the spatial interaction characteristics of three dimensions: City-City,City-Park and Park-Park.On this basis,the spatial pattern of cross-border economic corridor between China and Vietnam is analyzed,the characteristics and laws of multidimensional interaction between production and city in the corridor area are summarized and summarized,and the corresponding development strategies are put forward.Through the research,the paper draws the following main conclusions: 1)The four basic elements of cross-border economic corridor include cross-border traffic trunk lines,economic centers along the lines,industries with reasonable layout and cross-border factor flow.2)The crossborder economic corridor between China and Vietnam constructs a regional mobile spatial corridor with highway transportation and information network,forming a spatial pattern of three core nodes and multiple secondary nodes.However,the overall density of the network is low and its development is not balanced,and it is still in the primary stage of development.3)From the perspective of multi-dimensional interaction between production and city,the cross-border economic corridor between China and Vietnam shows the pattern of "strong in the east and weak in the west".The cross-border economic corridor outside China and Vietnam shows the pattern of "strong in the south and weak in the north".The interaction between border cities is relatively weak,but the interaction between border cities and cross-border industrial parks has achieved initial results.4)Multidimensional production-city interaction in cross-border economic corridors between China and Vietnam usually has regional proximity,and some types of interaction show node hierarchy,breaking through the geographical proximity to a certain extent,such as the connection between cities and science and technology parks and cities,etc.Information flows such as science and technology elements and innovation elements often take the lead in the flow of large cities,and large cities occupy the top of information elements.Research recommendations: 1)Establishing the Sino-Vietnamese Joint Planning Center and formulating and promulgating the Sino-Vietnamese Cross-border Economic Corridor Planning;2)Improving the construction of regional transportation facilities and promoting the linking role of portal cities;3)Open the Nanning-Fangchenggang-Guangning-Hanoi corridor,and expand the single corridor from Nanning to Hanoi into double corridor;4)Construct three levels of cross-border economic cooperation zones: raw material zone,processing zone and consumption zone,and build cross-border industrial chain.
