摘　　要：基于1990—2019年几内亚湾10个国家的面板数据,运用超效率SBM模型和Malmquist指数法,从静态和动态2个视角测算几内亚湾农业生态效率并分析其时空演变。结果表明,1990—2019年几内亚湾农业生态效率整体平稳,且近年呈轻微下降趋势;几内亚湾农业生态效率国家间差异明显,尼日利亚、圣多美和普林西比始终处于DEA有效,赤道几内亚(除1990年)、利比里亚始终处于DEA无效。从Malmquist生产率指数分解情况看,农业生态效率主要受技术进步的影响。基于结果,为提升几内亚湾农业生态效率,进而推动中国与几内亚湾国家合作,提出加强区域间生态农业合作;深化环境治理,推动科技创新;构建共享农业数据平台,形成规模经济效应;开展农业领域产业对接,推动中国与几内亚湾国家绿色合作发展等对策建议。Based on the panel data of 10 countries in the Gulf of Guinea from 1990 to 2019,the super-efficiency SBM model and Malmquist index method were used to calculate the agricultural ecological efficiency and analyze its spatiotemporal evolution of the Gulf of Guinea from static and dynamic perspectives.The results showed that the agricultural ecological efficiency in the Gulf of Guin⁃ea was stable from 1990 to 2019,and showed a slight downward trend in recent years.There were significant differences in agricultural ecological efficiency among countries in the Gulf of Guinea.Nigeria and Sao Tome and Principe had always been DEA effective,while Equatorial Guinea and Liberia had always been in DEA invalidity.From the decomposition of Malmquist index,agricultural eco⁃logical efficiency was mainly affected by technological progress.Countermeasures and suggestions were put forward to improve the agri⁃cultural ecological efficiency in the Gulf of Guinea and promote the cooperation between China and Guinea:Strengthen regional coop⁃eration in ecological agriculture deepen environmental governance and promote scientific and technological innovation;build a shared agricultural data platform to form economies of scale;carry out industrial docking in the agricultural field and promote the development of green cooperation between China and Guinea.
