A Study On The Impact Of Digital Services Trade Barriers On The Ternary Margin Of Domestic Digital Services Exports

With the rapid development of digital trade,countries have implemented a series of restrictive measures on digital service trade,making new digital service trade barriers increasing,and international regulatory policies and governance rules on digital trade have emerged,which constrain digital trade to different degrees under the umbrella of trade protectionism,thus constituting digital trade barriers.Existing studies have explored the impact of digital trade barriers on the ternary margin of export trade from a trade structure perspective is shallow,and most of the studies involving the trade structure perspective of export focus on the field of goods trade,while the impact of digital trade barriers on the ternary margin of digital service exports is not yet seen.In view of this,this paper tries to divide the digital service exports into the extended margin,the price margin and the quantity margin by drawing on the division of the ternary margin of service trade,and empirically analyzes the impact of digital service trade barriers on the ternary margin of national digital service exports through a fixed-effects model,and then proposes some policy recommendations based on the empirical findings,combining theoretical and empirical analysis.Firstly,this paper theoretically analyzes the mechanism of the impact of digital services trade barriers on the ternary margin of digital services exports in the country;secondly,integrating the UNCTAD data and OECD data,using the panel data of 59 countries from 2014-2021,with the digital trade restriction index as the key explanatory variable and adding the displayed comparative advantage,population size,services trade openness,and urbanization level as control variables.Econometrically analyze the impact of digital services trade barriers on the ternary margins of digital services exports in the country,and test policy heterogeneity and individual heterogeneity using digital services trade barriers policy division and country grouping regressions,respectively;again,applying trade costs and technological innovation to analyze the mechanisms of digital services trade barriers on the ternary margin of domestic digital services exports.The findings show that(1)digital services trade barriers inhibit the growth of domestic digital services exports in terms of volume;(2)digital services trade barriers promote the technological content of domestic digital services export subsectors and export products;(3)the five major policy areas of digital services trade barriers all significantly affect the price margins of domestic digital services trade exports,while only infrastructure and connectivity barriers and intellectual property barriers have a significant impact on the expansion(4)barriers to digital services trade increase the cost of domestic digital services exports and raise the level of technological innovation,and inhibit the growth of digital services exports through trade costs and technological innovation,and promote the technological content of digital services export subsectors and export products.Based on the above findings,this paper puts forward relevant policy recommendations in terms of double grasping the quantity and quality of digital exports,promoting technological innovation and reducing trade costs,digital infrastructure construction and intellectual property protection,and the openness of service trade.
