产业内贸易对中国农产品贸易影响的实证研究

Empirical Research on the Influence of Intra-industry Trade on Agricultural Products Trade in China

文章以农产品产业内贸易为研究对象,利用G-L指数,从分类和行业两个角度,对中国农产品产业内贸易的发展程度进行了评估。研究发现:虽然现阶段,中国农产品贸易仍然以由资源禀赋所主导的产业间贸易方式为主,但在某些农产品的贸易中,产业内贸易方式已经上升到了主要地位,并且未来有继续增长的趋势。进一步地,考虑产业内贸易的特殊性,建立中国农产品进、出口联立方程组模型进行实证分析,结果表明:农产品产业内贸易客观存在,并且其有助于促进中国农产品贸易的增长。因此,发展纵向一体化合作,力求在产品差异化竞争中取胜,是刺激产业内贸易增长,进而扩大农产品贸易规模的有效途径。

Based on the G-L index,this paper analyzes and evaluates the intra-industry trade of agricultural products from the perspective of classification and industry,respectively. We find that,although most current agricultural product trades are endowments-dominated inter-industry trade,intra-industry trade is also becoming increasingly important,at least among certain agricultural products. Considering the specialty of intra-industry trade,we do empirical research by adopting simultaneous equations that include both the import and export of agricultural products. The results show that,the intra-industry trade of agricultural products exists,and it helps to improve the development of agricultural product trades. Our findings suggest that,in order to improve the development of agricultural product intra-industry trade,it is necessary to enhance vertical industrial cooperation and the product differentiation.
