| At present,the process of economic globalization is gradually accelerating,the pattern of international trade is constantly optimized,the international division of labor between industries is becoming more and more refined,and more research has begun to focus on the service trade segmentation field.As countries continue to strengthen cooperation in the field of education,its important component-the development of education service trade will have an important impact on global and regional economy,culture,and politics.Since China proposed the "One Belt,One Road" initiative in 2013,and put forward the central idea of win-win regional cooperation from a strategic level,countries have been continuously strengthening educational cooperation within the region.Against the background of intensifying international competition and deepening regional cooperation,China’s education industry has developed in response to the trend,not only vigorously advocating from the frame design,but also steadily advancing the refinement into actual cooperation.Studying the education service trade of countries along “the Belt and Road” is conducive to further promoting the implementation of regional strategies and optimizing China’s position in regional education cooperation,and better serving and supporting the development of other industries such as politics,economy,and culture.At the same time,different from traditional trade statistics,the use of trade value-added indicators can more accurately measure and analyze the characteristics of current international education service trade in the context of global value chains.Based on the above background and existing research in the academic circle,around the theme of "One Belt One Road" countries(regions)education service trade,from the perspective of global value chain analysis of the status quo;through the network analysis method and QAP analysis method to study the network trade structure Features and influencing factors.The data period of this article is selected from 2000 to 2015.The basic data support is derived from the input-output data of189 countries and 26 industries in the EORA MEIO database.The main objects are 61 countries along “the Belt and Road”.By constructing five types of trade networks,TEX,DVA,FVA,RDV,and PDC,this article uses threshold filtering and hierarchical network construction to extract and visualize effective information from each network.Furthermore,it analyzes the structural characteristics of the trade network in three dimensions: macro,medium,and micro.In terms of empirical analysis,the network characteristics and influencing factors are analyzed through the QAP method.The results show that:(1)During the research period,the overall development of “the Belt and Road” region and the development of various countries had a substantial growth before 2008 and fell due to the impact of the financial crisis during that year,and then continued to grow steadily.The overall growth” trend is“first stable development,then rapid development”.(2)China has shown strong importance in the various indicators of the network,and economies such as India,Russia,and Singapore also have a relatively important position.The DVA network is a concentrated expression of various value-added trade networks and is more consistent with the overall network.(3)The TEX and DVA network communities have obvious characteristics and similar structures,while the FVA network community structure is significantly different from the first two,with individual individuals appearing.(4)Common territorial boundaries,common free trade agreements,bilateral trade scale,and bilateral economic scale are the key factors affecting the pattern of education service trade and value-added trade of countries along the “Belt and Road”.The common legal system and language factors are not obvious.Based on the above analysis,the author gives the following suggestions: First and foremost,optimize the distribution of educational resources in the region,and the advantageous countries will actively promote the common development of the less advanced countries.Besides,extend the value chain links to improve the quality of the development of intermediate services in the education industry.At the same time,establish and improve international regulatory systems and systems to enhance the ability to prevent risks in international education cooperation.In addition,strengthen and subdivide the supporting role of education services to other industries,and promote industrial integration and development. |
