Influence Of Digital Service Trade Barrier On Digital Service Export

In recent years,with the development of artificial intelligence,5G and other technologies,the traditional economic and social activities have been transformed and upgraded rapidly.During the 19 th National Congress,China proposed the strategy of "Digital China",which calls for building a strong network country,developing digital economy,fostering new economic growth points and forming new dynamic energy.It can be seen that digital development has become the direction with great development potential and an important growth pole of international service trade in recent years,and also has brought about great changes in production mode and product content.However,trade protectionism prevails in the development process and many countries adopt a conservative attitude which leads to a series of barriers that hinder digital services trade and even have the tendency to intensify.The form of barriers to trade in digital services is different from that of trade in traditional goods and is characterized by invisibility,scalability and diversity,which has a profound impact on the export of digital services and the development of the digital services industry in each country.Therefore,in the context of reverse globalization,it is important to analyze the impact of digital service trade barriers on digital service exports so as to fully develop digital service trade and unleash market vitality.In order to thoroughly study the impact of digital service trade barriers and find the path of digital service export growth,this paper provides an in-depth analysis of the impact of digital service trade barriers on digital service exports,both theoretically and empirically.First,we analyze the characteristics and development patterns of digital service trade barriers and digital service exports in 50 countries.Second,the reasons for the existence of digital service trade barriers are analyzed by theories.The analysis finds that digital service trade barriers have an impact on digital service exports through two mechanisms which are trade costs and technological innovation.Then,we analyze the regulatory theory of the economic level gap between countries,the level of network development,the security of the network environment,and the ternary marginal theory of exports.Finally,use a high-dimensional fixed-effects model by matching the WTO database and the OECD database from 2014 to 2019.Robustness tests and a heterogeneity analysis based on digital services industries,development levels of importing and exporting countries are conducted,followed by analyzing the moderating effects of the gap in economic levels between countries,network development levels,network environment security,and the impact of digital services trade barriers on digital services exports in a ternary marginal analysis.The following conclusions are drawn from this paper:(1)digital service trade barriers have a significant inhibitory effect on digital service exports.The results remain valid after robustness tests;(2)the inhibitory effect on digital service exports varies according to different digital service industries and development levels of countries.From the industry perspective,digital services trade barriers have significant inhibitory effects on services except other business services,among which the inhibitory effects are stronger on financial services and personal culture and entertainment services,the inhibitory effects on other business services industries are not significant;from the development level of countries,digital services trade barriers have significant inhibitory effects between developed countries,exports from developed countries to developing countries and from developing countries to developed countries,with stronger inhibiting effects on exports from developed countries to developed countries and developed countries to developing countries,and insignificant effects on exports between developing countries;(3)differences in economic levels between countries can enhance the inhibiting effects of digital services trade barriers on digital services exports;higher levels of network development and a safer network environment can weaken the inhibition of digital service trade barriers on digital service export;(4)the ternary marginal analysis of exports shows that digital service trade barriers have a positive impact on the type expansion margin and price aggregation margin,and a negative impact on the quantity aggregation margin of digital service exports.Finally,suggestions to reduce the impact of barriers and promote digital service exports are proposed at both national and enterprise levels.
