摘　　要：开放经济背景下，国际贸易内涵不断扩展，各国之间的农产品贸易关系日渐错综复杂，对一国农业价值链分工地位的考察必须将其置身于与其他国家的贸易关系网络中。基于1996～2013年的农产品贸易数据，本文首先采用社会网络分析方法研究了全球农产品贸易的整体格局，从网络中心性、网络联系强度和网络异质性3个维度对一国农产品贸易网络特征进行了刻画。分析结果表明，全球农产品贸易网络的演进是一个循序渐进的过程，且国家的贸易网络特征呈偏态分布。在此基础上，本文进一步实证检验了一国农产品贸易网络特征对其农业价值链分工地位的影响。研究结果表明，网络中心性、网络联系强度和网络异质性对一国的全球农业价值链分工地位具有稳健、显著的促进作用。The connotation of international trade has been expanding in the context of open economy. And the trade relationsof agricultural products between countries are becoming more and more complex. So it is wise and necessary that theinvestigation on a country's global agricultural value chain division status should be placed in the network of trade rela-tions with other countries. Based on the data of bilateral trade of agricultural products during 1996~2013, this paper us-es social network analysis method to study the overall pattern of global agricultural products trade. Then we portrayedthe characteristics of a country's agricultural products trade network from network centrality, network relation intensityand network heterogeneity. The analysis results show that evolution of global agricultural trade network is a gradual pro-cess, and the characteristics of national trade network are skewed distribution. On this basis, this paper further empiri-cally tests the impact of agricultural product trade network characteristics on the division of agricultural value chain.The research results show that the network centrality, network relation intensity and network heterogeneity have robust,significant and positive effects on division status of the global agricultural value chain.
