基于三阶段DEA模型的甘肃省贫困县金融扶贫效率实证研究

Empirical Study on the Efficiency of Financial Poverty Alleviation in Poverty Counties of Gansu Province Based on Three-Phase DEA Model

金融扶贫是打赢脱贫攻坚战的重要手段之一,对扶贫效果会产生较大影响。文章运用三阶段DEA模型对甘肃省贫困县的金融扶贫效率进行测算,发现各县区扶贫综合技术效率处于低水平,规模效率普遍较好,且规模报酬递增的县区数量远多于规模报酬递减的数量,而纯技术效率差异较大。此外,外部环境因素也会对金融扶贫效率产生不同程度的影响。

Financial poverty alleviation is one of the important means to win the battle against poverty, and it will have a greater impact on poverty alleviation. The paper uses the three-stage DEA model to measure the financial poverty alleviation efficiency of poverty-stricken counties in Gansu Province, and finds that the comprehensive technical efficiency of poverty alleviation in all counties is at a low level, the scale efficiency is generally good, and the number of counties with increasing returns to scale is far more than the decline in scale returns.The amount of pure technical efficiency varies greatly. In addition, external environmental factors will have different degrees of impact on financial poverty alleviation efficiency.
