Based on the trade data of China's import and export with the countries along the line, the paper calculates and analyzes the proportion and change characteristics of China's total import and export volume with the countries around the world, uses the dominant comparative advantage index , and explores the industrial correlation between China and the countries along the "one belt and one road" based on China's own comparative advantage. Trade tightness. On the basis of this, we introduce the stochastic frontier gravity model and empirically study analysis of the trade efficiency between China and the "one Belt and one Road" countries, in order to look forward to the future trend and development of China's "one belt and one road" initiative.
