摘　　要：进口议价能力是衡量一个国家贸易竞争力的关键指标,更是确保国家粮食安全的关键。文章使用2000—2020年粮食贸易双边数据和世界银行数据,基于双边随机前沿模型和社会网络模型对进口国贸易网络特征和议价能力进行科学测度,并探讨进口国贸易网络特征对进口国议价能力的影响。研究发现,进口中心度和进口强度对议价能力有负面影响,而进口异质性则显著增强了议价能力。此外,通过分析经济发展水平和制度环境对进口议价能力的调节作用,结果显示这两个因素均能正向影响进口国贸易网络特征对议价能力的影响。这些发现强调了经济实力和健全的制度环境在提升国家贸易议价能力中的重要性。Import bargaining power is a key indicator for measuring a country's trade competitiveness,and it is even more crucial for ensuring China's food security.Using bilateral data on food trade and World Bank data from 2000 to 2020,the article scientifically measures the trade network characteristics and bargaining power of importing countries based on bilateral stochastic frontier model and social network model,and explores the impact of importing countries'trade network characteristics on the bargaining power of importing countries.It is found that import centrality and import intensity have a negative impact on bargaining power,while import heterogeneity significantly enhances bargaining power.Furthermore,by analyzing the moderating effects of the level of economic development and institutional environment on import bargaining power,the results show that both factors positively influence the impact of importing countries'trade network characteristics on bargaining power.These findings emphasize the importance of economic strength and a sound institutional environment in enhancing a country's trade bargaining power.
