Research On The Impact Of Digital Economy Development On The Technical Complexity Of Service Trade Export

The rise of a new round of scientific and technological revolution makes service trade become a new focus of global trade competition,and governments around the world have gradually focused on the improvement of the "quality" of service trade,and the key to improve the "quality" of service trade is to improve the technical complexity of service trade export(Zhang Yu,2017).The development of digital economy provides opportunities for service trade to find new growth points in the complex global economic and trade situation,but also brings new challenges for the improvement of technical complexity of service trade export.Therefore,studying the impact of digital economy development on the technical complexity of service trade export can provide a basis for countries to formulate digital economy development strategies in line with their national conditions and improve the technical complexity of service trade,which is of great significance for the high-quality development of global service trade.This paper uses the network readiness index published by the World Economic Forum to measure the development of digital economy.Meanwhile,based on the database of United Nations Conference on Trade and Development,it calculates the technical complexity of service trade exports of 62 countries from 2008 to 2020.The data shows that the development of global digital economy is rising.The digital economy level of high-income countries is always higher than that of low-and middle-income countries,and Oceania,North America and Europe have strong digital economy level.The service trade of various countries has a good momentum of development.The technical complexity of service trade exports of high-income countries is higher than that of low-and middle-income countries,and that of producer services is higher than that of consumer services.On this basis,a fixed effect model is constructed to analyze the influence of digital economy development on the technical complexity of service trade export.The results show that the development of digital economy has a significant promoting effect on the technical complexity of service trade export during the sample period.Compared with low-and middle-income countries,the development of digital economy plays a more significant role in promoting the technical complexity of service trade exports in high-income countries.Compared with domestic service industry,the development of digital economy plays a more significant role in promoting the technological complexity of producer service industry exports.The mechanism test shows that the development of digital economy can promote the technological complexity of service trade export through productivity effect,trade cost effect and demand-induced effect.Based on the research conclusions,this paper puts forward the following countermeasures and suggestions: enhance the integration degree of digital economy and service trade,make full use of the advantages of digital economy,and promote the development of service trade;according to the characteristics of different countries and service industries,the differentiated development should be carried out;the government vigorously develop the digital economy,improve the construction of digital infrastructure and improve the technical complexity of service trade export;encourage technological innovation,raise the productivity of service enterprises and ensure the sustainable development of trade in services.
