摘　　要：参与全球农业价值链,是保障国家粮食安全、提高农业产业竞争力和影响力的重要举措。基于TiVA数据库和UN COMTRADE数据库测算64个国家全球农业价值链的参与程度与分工地位,采用社会网络分析方法构建全球农业对外投资网络,实证分析农业对外投资布局对一国参与全球农业价值链的影响。结果表明,当前全球农业对外投资网络由发达国家主导;网络中心性和网络异质性对全球价值链地位有显著正向影响,即一国越处于网络中心且投资金额越分散,其价值链地位越高;网络规模有负向影响,盲目拓展投资网络的规模化优势难以抵消农业对外投资的高风险。基于研究结果,从分环节优化农业对外投资布局、深耕既有农业对外投资网络、逐步嵌入发达国家主导的农业对外投资网络等方面提出促进中国价值链地位攀升的建议。Participating in the global agricultural value chain is an important measure to safeguard a country’s food security and enhance its competitiveness and influence of the agricultural industry.Based on the TiVA database and the UN COMTRADE database,this paper estimates the participation and status of 64 countries in the global agricultural value chain,uses social network analysis to construct a network of global agricultural foreign investment outflow,and empirically analyzes the impact of the agricultural foreign investment layout on a country’s participation in the global agricultural value chain.The results show that the global network of agricultural foreign investment outflow is currently dominated by developed countries.Network centrality and network heterogeneity have a significant positive effect on a country’s position in global value chain,that is,the higher a country’s centrality and the more dispersed its investment,the higher its position in the value chain.Network scale has a negative impact,and the advantages of scaling up blindly is difficult to offset the high risks of agricultural foreign investment outflow.Based on the research findings,this article proposes suggestions for improving the status of the value chain by optimizing the layout of agricultural foreign investment outflow in different links,deepening the existing agricultural foreign investment outflow network,and gradually intergrating into the network dominated by developed countries.
