The "Belt And Road" Trade Facilitation Level And Its Impact On The Three Margins Of Export

Under the background of economic globalization,the main trade barriers are no longer the traditional tariff and non-tariff barriers,but the invisible barrier,that is,the "non-efficiency of trade" is the main factor that affects the growth of global trade.Among them,trade facilitation is one of the important means of resolving trade inefficiency.President Xi pointed out at the G20 summit that there are multiple risks and challenges in the face of the current lack of growth momentum,weak demand,repeated financial market turmoil,and persistently low international trade and investment.All countries should build an open world economy and continue to promote trade and investment liberalization and facilitation.At the same time,China has put forward the "Belt and Road" strategic concept.It clearly proposes to build an all-dimensional,three-dimensional interconnection and interoperability network and concentrate on solving trade facilitation problems among countries along the route.The trade potential of the "Belt and Road"countries is huge,and the future economic development is unstoppable.This paper analyzes the existing research literature on the trade facilitation of countries along the "Belt and Road" initiative and finds that scholars mostly use the subjective trade facilitation assessment indicators to measure the level of a country’s trade facilitation.In order to more objectively measure the level of trade facilitation in countries along the"Belt and Road"initiative,this article uses the OECD trade facilitation index system based on the WTO Trade Facilitation Agreement to comprehensively measure the trade of countries along the"Belt and Road"initiative.Facilitation level.On this basis,the relationship between trade facilitation and export trade was studied intensively.In previous studies,when conducting studies on the relationship between trade facilitation and export trade,we focused on exploring the relationship between trade facilitation and total trade volume,and did not reveal the specific impacts bet,^ween the two.Therefore,this paper uses the framework of the ternary margin to explain the path of trade facilitation to export trade.The results show that trade facilitation has a significant role in promoting export trade among countries along the "Belt and Road",and the impact on expansion margins is significantly higher than that of intensive margins(whether price or quantity).Moreover,trade facilitation is more conducive to the promotion of Southeast Asia,West Asia,North Africa,and Central and South Asia along the "Belt and Road" initiative than to Europe.Finally,based on theoretical analysis and empirical results,this paper proposes relevant policies to improve the level of trade facilitation in countries along the "Belt and Road" and improve export trade.
