中蒙俄经济走廊连接了中国北方、俄罗斯西伯利亚地区和蒙古国，也连接了欧洲经济圈和亚洲经济圈，是“一带一路”倡议的重要经济廊道。由于该区域自然条件所赋予的丰富的森林资源，使得木质林产品生产与贸易成为该走廊重要的经贸活动。本文选取该区域森林资源，研究木质林产品产业内贸易水平。通过联合国粮农组织的中蒙俄林业贸易数据，利用产业内贸易理论，计算1997年-2016年20年内中蒙中俄之间的木质林产品产业内贸易指数G-L指数以及MIIT指数，以衡量中俄、中蒙之间的木质林产品产业内贸易水平，从而分析贸易过程中中国的外贸调整能力以及各国的产业内贸易优势及劣势所在，以提出相应建议促进该区域木质林产品产业内贸易的发展。

The China-Mongolia-Russia Economic Corridor connects North China, the Russian Far East and Mongolia. It also connects the European Economic Circle and the Asian Economic Circle. It is an important economic corridor for the “Belt and Road Initiative”. Due to the abundant forest resources given by the natural conditions of the region, woody forest products and trade have become important economic and trade activities in the corridor. This paper selects the forest resources in the region to study the level of intra-industry trade of woody forest products. Based on the data of forestry trade between China, Mongolia and Russia of FAO and the theory of intra-industry trade, the intra-industry trade index G-L index and MIIT index of woody forest products between China, Mongolia, China and Russia in the period of 1997-2016 are calculated to measure the intra-industry trade level of woody forest products between China, Russia and Mongolia, so as to analyze the adjustment ability of China's foreign trade and the production of various countries in the course of trade. The advantages of intra-industry trade are to put forward corresponding suggestions to promote the development of intra-industry trade of woody forest products in the region.
