Research On The Evolution Of Global Service Trade Network And Service Space

With the in-depth development of knowledgization and globalization,the export of service has increasingly become a new trend of economic development in industrialized countries.In the new round of scientific and technological revolution,technological innovation has given the unparalleled development potential of service industry,continuously expanding the extension and connotation of service trade,which is increasingly becoming an important growth engine of the global economy.At present,China is in the important historical stage of the great rejuvenation of the nation.Adhering to opening up and to be a trade power is an inevitable choice for China’s peaceful rise.To this end,grasping the development trend of global service trade and analyzing the structure of global service trade have important practical significance for China to actively participate in the global service trade competition.However,current research on international trade issues has focused on the field of goods trade,while service trade has received less attention,and few studies have explored global service trade issues from a geographical perspective.Based on the geographical characteristics of global service trade and the industrial structure,this paper analyzes the spatial and temporal evolution characteristics of global service trade network and constructs global service space through social network analysis method and product space theory.Specifically,in the global service trade network,this paper focuses on the overall attributes of the network,node characteristics and cyberspace structure.It focuses on the spatial and temporal evolution characteristics of the overall service trade network and the process of core-edge structure changes.The dynamic evolution of community division and other content has realized the spatial profile analysis of the global service trade network.On this basis,this paper further analyzes the relationship between industrial structure and service space of global service trade,and uses the detailed data of national service trade exports to analyze the comparative advantages of national service trade by using the revealed comparative advantages index.Combined with the diversity of national service capabilities and the ubiquitous characteristics of service products,the industrial competitiveness of service trade in various countries was examined.The global service space is built by the proximity relationship between service products of various countries,and the social network analysis software is used to visualize the service space to study the dynamic evolution of the global service space.By analyzing the characteristics of global service space structure and the main service categories,combined with the geographical characteristics of the global service trade network,this paper mainly draws the following conclusions:(1)The global service trade still presents the “one superpower” pattern led by the United States.The Atlantic coast has become the absolute center of global service trade,and there is still a big gap between East Asia and North America and Europe.(2)European countries have strong competitiveness in service trade industry,and outperform North America and Asia Pacific countries in terms of national service capacity diversity and service product ubiquity;(3)There is a deviation between the global service space center and the service trade industry,and the service industry transformation and upgrading of the less developed countries is difficult;(4)China’s service exports are mainly concentrated in the traditional service field,and the competitiveness of emerging service industry which is knowledge and technology-intensive still needs to be improved.
