Based on national foreign trade big data, the status of import and export trade and investment cooperation of countries along the 'Belt and Road' are analysed in depth to study the changes of ecological environment in the local market. Using comparative advantage index, industry sensitivity index and trade competitiveness and complementarity analysis, this paper systematically combined the economic and trade cooperation between China and the countries along the `Belt and Road', and analysed in details the main import and export regions, import and export destination countries, trade methods, enterprise subjects and product types. By analysing the situation of national economic and trade cooperation along the `Belt and Road', it is of great significance to quantitatively describe the general situation of China foreign trade in order to promote the orderly and free flow of economic factors, the efficient allocation of resources and the deep integration of the market, and to promote a greater scope, higher level and deeper regional cooperation among the countries along the route.
