| Since 1980,American service industry and service trade have been fully developed and played an important role in the national economy.The year-to-year increasing scale of service trade import and export trade in services and keep the surplus,the United States trade in services to finance,insurance,patent and other modern service trade industry development,realize the optimization and upgrading of the structure,at the same time,us service trade export market includes not only the developed countries and developing countries,is plural.Therefore,it is of great significance to study the export potential of American service trade and its influencing factors.Firstly,it starts with the traditional and modern service trade theories such as the competitive advantage of Deere doffer and the national competitive advantage,analyze the theory of service trade and export potential and so on;secondly,the study on the current situation of the service trade of the United States shows that the import and export of the service trade of the United States are large and maintain a long-term surplus,technology-intensive industries play an important role in the development of service trade,the market is characterized by diversification.Thirdly,through the establishment of gravity model,the data of 50 trading partners from 2006 to 2018 were selected to make an empirical analysis of the export potential.It was found that the export potential of the American service trade was mostly "potential reshaping" countries and "huge potential" countries,while "potential pioneering" countries were only a few.Then,the influence factors of export potential is analyzed from two aspects,first of all,according to the results of the regression model study found that the economies of scale,foreign direct investment,service trade openness and common language to promote the export of service trade,distance hindered the development of service trade,and then based on Michael porter’s theory of national competitive advantage of the other factors which affect the export potential is analyzed,it also provides some experience for the development of service trade in other countries.The innovation of this paper: first,this paper makes an empirical analysis of export potential by selecting panel data from 50 US trading partners from 2006 to 2018,breaking the tradition of bilateral and small economy analysis.The export potential of emerging economies is analyzed from the perspectives of overall,regional and emerging economies.Secondly,as for the study of influencing factors,this paper not only makes qualitative and quantitative analysis of factors such as economic scale and FDI of service industry based on the regression results of the model,but also makes comprehensive analysis of influencing factors from the micro,meso and macro levels respectively according to the "Diamond model",which is innovative to a certain extent. |
