Measurement And Improvement Strategy Of Digital Trade Competitiveness Under The Framework Of "Three-Chain Integration"

Digital trade has maintained rapid development and changed business models and consumer consumption patterns gradually.It has become a new impetus for economic growth in countries around the world.This paper studied the digital trade competition determination mechanism,the performance of digital trade development in various countries in the world,and the impact of digital trade development on traditional international trade through trade theory analysis,evaluation system demonstration and Zhejiang case analysis.Based on the perspective of global value chain,global governance chain,global innovation chain,this paper analyzes the digital trade competition decision mechanism: the accumulation of acquired factors from the perspective of global value chains,innovation from the perspective of global innovation chains,and the improvement of the level and the grasp of external markets from the perspective of the global governance chain.The development of digital trade can be achieved only through the interaction and interdependence of the "three chains".The digital trade-related data of major countries were collected,sorted and matched based on the supplementary form of the world input-output table.13 variables were set from the three dimensions of volume,structure,and innovation to form an evaluation system.This paper uses entropy method with improving the timing variable to analyze the digital trade competitiveness rankings of 47 countries from 2010 to 2014,then make a detailed comparison and analysis of specific situations to obtain the current level of development,deficiencies and improvement directions of China’s digital trade.This paper takes Zhejiang Province,where China’s e-commerce is highly developed,as a typical case.Through industrial policy analysis,analysis of the development of the information industry and e-commerce,and empirical analysis of cross-border e-commerce,it explores the digital trade development characteristics and optimization path of digital trade in Zhejiang Province.The corresponding suggestions are put forward from the aspects of optimizing environment,combining model innovation with technology innovation,and attaching importance to participating in global digital trade governance.
