| In recent years,the continuous development of economic globalization has made international relations increasingly close,and digital trade based on information services has begun to attract the attention of all countries,besides,information services are gradually becoming the core field of service trade.However,the service-oriented trade of China at this stage is still dominated by traditional industries,while information service trade is relatively backward in terms of trade relations and industrial structure.Trade intelligence can dynamically monitor trade information between countries and provide data support or decision-making basis for government and enterprise decisionmaking.Therefore,how to use the huge and complex trade data to analyze,and summarize valuable trade intelligence,for the government and enterprises to guide the decision-making,so as to get out of China’s current dilemma of information service trade development,has become a key issue that needs to be solved urgently.Therefore,this study takes the major information service trade countries in the world as the research object,conducts intelligence research on information service trade from the perspective of trade intelligence and based on the social network method,and puts forward targeted trade information that is conducive to the development of China’s information service trade.Based on the United Nations Commodity Trade Statistics Database,this study discusses the spatial and temporal changes of national nodes and trade relations from the perspective of the overall network of information service trade and the individual network of China.Firstly,through the trade volume data of information services in the database of the United Nations Conference on Trade and Development,21 sample countries were selected by binarization,and then based on the United Nations Commodity Trade Statistics Database,the information service trade data of the sample countries from 2015 to 2020 were obtained and converted into matrix form,forming an international information services import and export trade social relationship network,and grasping the international information service trade network as a whole.Through the network indicators on centrality and density,the social relationship between the import and export of information services is quantitatively analyzed,and then the clustering analysis and core-edge analysis of the block are used to explore the countries in the information service trade network from the perspective of national relations,classify the countries with similar characteristic attributes,and use the Apriori association rule to obtain the correlation between information service trade relations,trade volume and national GDP.Then,further analysis of China’s individual network,with China as the node center,forms and analyzes the information service trade network of China and other countries,so as to obtain information service trade intelligence about China.According to the visualization results,the visualization network of information service import and export trade was relatively stable,while the individual network of information service trade in China changed greatly.According to the analysis of network indicators,from the network density,network centrality and clustering coefficient,the United States,Russia,Italy and Sweden ranked high and stable in each indicator,while 6 countries,including China,were at the bottom.According to clustering and core-edge analysis,combined with network indicators and actual conditions,the countries in the network are divided into three types,namely "core countries of information service trade","developing countries of information service trade" and "edge countries of information service trade".Finally,this paper pointed out that China needs to expand the information service trade network,actively seek industrial transformation,use information service trade intelligence as the data support and decision-making basis of the government and enterprises,and integrate it with the current international policy and development strategy,so as to get rid of the current situation of "information service trade marginal countries". |
