中文摘要：

本文利用贸易互补性指数、贸易结合度指数及出口集中度指数,对1998-2014年中国与蒙古、俄罗斯的贸易发展历程及进出口产品格局进行分析,并将贸易结合度指数和出口集中度指数引入引力模型计算中蒙和中俄的贸易潜力。中国与蒙古、俄罗斯的贸易结构具有很强的互补特征,根据引力方程测算出贸易总额与贸易结合度成正向关系,与出口集中度成负向关系;中蒙贸易潜力在＂一带一路＂倡导下迅速提升,但中国与俄罗斯两国双边贸易潜力尚未充分发挥,仍有进一步扩大的空间。

英文摘要：

This paper analyzes trade development progress and trade patterns of Sino and Mongolia- Russia from 1998 to 2014 by using trade complementary index,trade union index and export concentration index,and the trade union index and export concentration index are introduced into the gravity model to calculate the Sino- Mongolia and Sino- Russia trade potential. The trade structure of China has strong complementary features with that of Mongolia and Russia; according to the gravity equation,the trade export volume has been measured into a positive relationship with the trade integration,and a negative relationship with the concentration of exports; in the initiative of ＂One Belt and One Road＂,the trade potential of Sino-Mongolia has improved speedily,while the bilateral trade of Sino-Russia has not been fully exploited yet,and there is still room for further expansion.
