Abstract: As a bridge between production and consumption, trade circulation industry plays an extremely important role in the development of regional economy and transformation of economic growth pattern,and urbanization can strengthen and coordinate their relationship. Applying Spatial Durbin Model and choosing the urbanization level as a regulation factor, the paper analyzes the influence of the trade circulation industry specialization on the transformation of economic growth pattern by using domestic sector of “Belt and Road” spatial panel data from 2005 to 2015. The results show that: the trade circulation industry specialization level in areas along“Belt and Road” is not balanced, and transformation of economic growth pattern exists a clear spatial correlation effect under the role of related factors; the positive local effects and spatial spillover effects of the specialization of trade circulation industry on the intensification of economic growth in “Belt” areas are obviously higher than in “Road” areas; the urbanization has a significant moderating role, especially its leverage effect and demonstration effect are more significant both inside and outside of the province in “Belt” regions. Therefore, we should improve trade specialization degree and the rate of city and play its positive role on the transformation and upgrading of economic structure in “Belt and Road” strategic process.

Key words: “Belt and Road”, trade circulation, economic growth pattern, urbanization, moderating effect
