This paper classifies agricultural products into six categories,and uses Grubel and Lloyd,Azhar and Elliot methods to analyze the development situation of China-ASEAN intra-industry trade of agricultural products from 2004 to 2013 from the perspectives of scale,level and structure.The result shows that firstly,the intra-industry trade scale of China-ASEAN agricultural products remains a trend of swift growth in the past ten years,but the speed is slowing down in recent years; secondly,the intra-industry trade level of China-ASEAN agricultural products is very low,while the characteristics of intra-industry trade of labor-intensive agricultural products are much significant; thirdly,both horizontal and vertical intra-industry trade are playing more and more important roles in China-ASEAN agricultural trade,while the quotient of vertical intra-industry trade is larger,but most categories of agricultural products’ intra-industry trade are horizontally-domintated.Therefore,this paper proposes that China should reduce the trade deficit of land-intensive agricultural products,intensify the horizontal differentiation characteristics of agricultural products and deepen the trade cooperation of agricultural products with ASEAN countries selectively.
