中国植物油料产业内贸易的实证研究An empirical study on intra industry trade of vegetable oilseeds in China

Abstract

产业内贸易对我国油料安全具有深远影响。为推动我国植物油料贸易和产业的健康发展，从总体和分类两个层面分别计算2011—2020年中国植物油料的Grubel-Lioyd指数、Bruelhart边际产业内贸易指数以及Thom & McDowell指数，分析我国植物油料贸易现状，并提出相应建议。结果表明：近年来我国植物油料贸易增量主要来自产业间贸易，植物油料的总体产业内贸易水平偏低；Thom & McDowell指数表明近年来我国植物油料产业内贸易主要来自垂直型产业内贸易。基于此现状，针对性地提出实施差异化的植物油料产业内贸易发展战略，建立植物油料贸易可持续发展的长效机制，培育具备国际竞争力的大型农企集团，提升植物油料风险管控能力等相关政策建议。Intra industry trade has a profound impact on the safety of oilseeds in China. To promote the healthy development of China′s vegetable oilseeds trade and industry, the Grubel-Lioyd index, Bruelhart marginal intra industry trade index and Thom & McDowell index of vegetable oilseeds from 2011 to 2020 were calculated respectively from the overall and classification levels, further the current situation of vegetable oilseeds trade in China were analyzed and corresponding suggestions were proposed. The results showed that the increase of China′s vegetable oilseeds trade in recent years mainly came from intra industry trade, and the overall intra industry trade level of vegetable oilseeds was low. Thom & McDowell index showed that in recent years, China′s intra industry trade of vegetable oilseeds mainly came from vertical intra industry trade. Based on this, relevant policy suggestions were put forward, such as implementing a differentiated intra industry trade development strategy for vegetable oilseeds, establishing a long-term mechanism for the sustainable development of vegetable oilseeds trade, cultivating large-scale agricultural enterprise groups with international competitiveness, and improving vegetable oilseeds risk management and control capabilities.
