摘　　要： 以2015年天津对"一带一路"沿线63国OFDI的横截面数据为样本,运用改进的DEA交叉模型与聚类分析,探讨天津对63个国家OFDI的效率及其分布规律,并对DEA无效或弱有效东道国的OFDI结构调整提供建议。结果表明:天津对"一带一路"沿线国家OFDI的效率为中低水平,OFDI效率分布的国别差异较大,而区域差异不大。按照投入类型,63个国家分为4类,新加坡、埃及、泰国以及阿尔及利亚分别是4类东道国OFDI结构调整和效率改进的标杆。 This study is aim to evaluate the efficiency and discuss distribution of OFDI of Tianjin with OFDI structural adjustment for ineffective or weakly effective host countries,employing improved DEA crossover model and clustering analysis,taking examples of the cross-sectional data of 63 countries along ＂The Belt and Road ＂in 2015. the result shows that： firstly,the efficiency of the OFDI isrelatively low; secondly,the difference of OFDI efficiency among 63 host countries is quite significant,but the regional difference is rather small; finally,according to the type of input,63 countries can be divided into four categories. Singapore,Egypt,Thailand and Algeria are respectively the benchmarks for ineffective or weakly effective host countries in the four categories to adjust the efficiency of OFDI.
