Study On The Influence Of Digital Trade Barriers On The Complexity Of Service Export

As the digital economy has entered a new era,digital trade has gradually become a new way to conduct international trade and bring new vitality to international trade and global economic development.At the same time,digital trade is increasingly penetrating the service sector.Digital technology and digital products are widely used in all walks of life.Digital trade barriers are one of the important factors restricting the further development of digital economy.With the new information technology as the driving force,the traditional service industry has gradually shifted to digitization.Therefore,digital trade barriers are likely to have some impact on international trade in services.At present,not much research has been done on the impact of digital trade barriers on the complexity of countries’ services exports.Therefore,studying the impact of digital trade barriers on the complexity of services exports will help countries to pay attention to the possible disadvantages of digital trade restrictions,so that in the global digital trade environment,it will be helpful for our country and even the world to better promote innovation and development of services,and bring lessons for enhancing national competitiveness of services.This paper firstly combs the literature on the relationship between digital trade barriers and the complexity of service export,then analyzes the development of global digital trade barriers and the complexity of service export in sample countries.Then,from the three aspects of raising the cost of trade in services,reducing product innovation ability and cluster effect,the paper explains the mechanism of the impact of digital trade barriers on the complexity of service export.In this paper,13 sample countries were selected to calculate the complexity of national service exports from2014 to 2020,using the Organization for Economic Cooperation and Development(OECD)Digital Trade Restraint Index(DSTRI)to measure digital trade barriers.Based on the empirical analysis of the fixed effect model,the relationship between the two is examined,and the research in the field of industry is analyzed.It is found that digital trade barriers inhibit the complexity of service export.The increase in population size,trade openness and economic development will significantly increase the complexity of service exports;Both insurance services and financial services,as well as computer and information services,have served as a deterrent.Through the analysis,this paper summarizes the following three revelations:(1)Promoting cross-border integration of digital services mechanisms and weakening digital trade barriers;(2)Strengthening the supporting facilities for the development of the service sector;(3)Encourage technological innovation to ensure the sustainable development of digital trade.
