| At the moment,the world economy is becoming more diversified.It is based on the "Silk Road" culture.To comply with the requirements of the global economic structure of the era of change.In 2013,President Xi Jinping put forward the important propose of "The Silk Road Economic Belt" and "21th century Maritime Silk Road"(referred to as "The Belt and Road" propose).Since the propose was made up?more and more countries and regions join the "The Belt and Road",on the basis of the propose,these countries make development strategy and plan in accordance with the actual situation."The Belt and Road" has become a driving force in Asia,Europe,Africa,the propose playing an important role in the growth of regional economic development and creating new growth model.As an important part of the "Belt and Road" propose,the "21th century Maritime Silk Road" has gathered many port cities with abundant economic vitality and great trade potential along the route.lt is not only the entire strategy implementation important support part,also the regional economic development important growth point.However,how to play a better role in economic diffusion and comprehensive connection of the main cities of the "21th century Maritime Silk Road",and enhance the organic interaction and connection with the"Silk Road Economic Belt" are all important issues.In order to realize the "Belt and Road" propose,it is still a key issue to be paid attention to.From the current urban network research results,the current urban linkage and urban network theory has actually expanded from simple spatial linkage to economic,technical and other fields of complex linkage.However,the current research is not systematic,relatively single,the analysis of cross-regional inter-city linkage effect is not enough.The position and role of major cities along the "21th century Maritime Silk Road" in the overall propose have not been systematically analysed,concrete and effective analytical methods and techniques are lacking.Therefore,it is difficult to study in depth the linkage mechanism and promoting role of the central city to the strategic advance of the "21th century Maritime Silk Road".This makes the guiding value in promoting inter-regional economic cooperation and urban competitiveness of the "21th century Maritime Silk Road" propose has been weakened.Based on this,this paper studies the urban linkages and interactions within the scope of the"21th century Maritime Silk Road "in the perspective of urban linkage.Systematic description and quantitative analysis of the linkage structure and characteristics of central cities based on financial industries along the route was made in this thesis.Firstly,this paper summizes the research progress of urban linkage theory,urban network theory and central city theory at home and abroad,which lays a theoretical foundation for the research of this paper.Secondly,this paper defines the central city of the " 21th century Maritime Silk Road"and constructs the central city network model by combining the spatial distribution data of the headquarters and branch offices of financial enterprises.Furthermore,on the basis of the " 21th century Maritime Silk Road" central city network model,the network connection degree and the relative connectivity rate between the central cities are carried out.Based on the analysis of urban basic linkage structure and urban k-core structure,the paper describes and depicts the relationship and structure of the central city of the "21th century Maritime Silk Road".Finally,according to the current "Belt and Road1"propose and the economic development conditions of each city,the status and role of the central city are classified and evaluated on the basis of the above urban linkage study,the core cities of each route of the "21th century Maritime Silk Road" were determined,and the propositions of the "21th century Maritime Silk Road"construction was put forward,aiming at realizing the important value of "Belt and Road" propose in the process of building the "Human destiny community". |
