The original intention of the Belt and Road Initiatives is to achieve a win-win and shared development of all countries. Does economic cooperation between the countries along the Belt and Road really promote inclusive growth? This paper conducts an empirical study on this issue. Based on the trade data of 54 countries along the Belt and Road in 2006~2017, the gravitational model and social network analysis method are used to obtain the structural characteristics of economic cooperation network between the countries, and then the GMM method is used to test. The research results show that: (1) the Belt and Road trade-related network shows a trend of increasing. Russia, Turkey, China and other countries are at the core of the network; (2) the economic cooperation between countries along the Belt and Road can indeed achieve inclusive growth. It is consistent with the original intention of the Belt and Road Initiatives; (3) in the cooperative network, the proximity centrality has the highest impact, the degree center degree is the second, and the intermediary center degree is the last. This shows that the direct link of the Belt and Road trade related network has the most significant and prominent influence. This article is of great significance for better promoting the construction of the Belt and Road and promoting mutual benefit and win-win results among countries along the route.
