英文摘要：

Since the proposition of＂Belt and Road Initiative＂, researches on trade between China and countries along the Initiative area have increased. However, it is relatively rare to study trade network taking China and those countries as a whole. In this article, we utilize a social network analysis method to analyze the characteristics, trade groups as well as core-periphery structure and its evolution of this trade network. Then we analyze the structure of sub trade network of China and the Southeast Asian countries. The results show that density of the trade network established by China and countries along＂Belt and Road Initiative＂areas has increased, coupled with growing number of core countries. Meanwhile, China＇s core degree in this trade network has increased with China being the most important core country in 2013. What＇s more, China becomes the core country in the sub trade network of China and the Southeast Asian countries as well. Based on this analysis, we propose that during the process of promoting＂Belt and Road Initiative＂construction, China should rely on policy communication to reduce trade barriers and improve trade facilitation with countries along the Initiative area. In particular, it should be set as the priority to facilitate trading conditions with core countries in the Initiative area trade network for further enhancing China＇s core position in this network. What＇s more, China should make good use of the advantage of being the core position in the network, play an active role of being the area core country and promote the construction and development of＂Belt and Road Initiative＂.
