基于三阶段DEA模型的宁夏水库移民后扶资金使用效率分析研究

Research on the Efficiency of Using Subsidy Funds for Reservoir Resettlement in Ningxia Based on the Three Stage DEA Model

水库移民为国家经济建设做出了重大贡献,对水库移民的妥善安置和后期扶持是社会和谐稳定的关键。为了能够客观、准确和科学地对2019-2021年期间宁夏水库移民后扶资金使用效率进行评价,以宁夏14个典型区县为研究对象,采用三阶段DEA模型对后扶资金的使用效率进行分析研究,并通过SFA方法剔除了环境因素和随机干扰对资金使用效率的影响。分析结果表明:(1)运用三阶段DEA模型评价宁夏水库移民后扶资金使用效率是合理的。(2)剔除环境因素和随机干扰的影响后,第三阶段后扶资金使用效率较第一阶段分别提高55.1%、87.8%和32.4%,提升了后扶资金使用效率的评价准确度,可为后续项目的开展提供参考。(3)研究的3个环境因素中,提高受教育程度已逐步成为提高后扶资金使用效率的有效途径。(4)通过DEA-Malmquist动态分析,ZN县、PL县和LT区等6个区县的全要素生产效率较低,主要因素为资金管理效率低下和规模配置不当导致。后续将依据分析结果,通过强化管理、优化项目规模和类型的方式,分类施策、精准扶持,不断提高移民生活质量。

Reservoir immigrants have made significant contributions to the national economic construction,and proper resettlement and support for reservoir immigrants are the keys to social harmony and stability.In order to objectively,accurately,and scientifically evaluate the efficiency of the use of post resettlement funds for reservoir immigrants in Ningxia from 2019 to 2021,a three-stage DEA model is used to analyze and study the efficiency of post resettlement funds in 14 typical districts and counties of Ningxia.The SFA method is used to eliminate the impact of environmental factors and random interference on the efficiency of fund use.The analysis results indicate that:①It is reasonable for this paper to use the three-stage DEA model to evaluate the efficiency of the use of post resettlement funds for reservoirs in Ningxia.②After removing the influence of environmental factors and random interference,the utilization efficiency of the support fund in the third stage increased by 55.1%,87.8%,and 32.4%compared with the first stage,respectively,which improves the accuracy of the evaluation of the utilization efficiency of the support fund and can provide a reference for the development of subsequent projects.③Among the three environmental factors studied in this article,improving education level has gradually become an effective way to improve the efficiency of using support funds.④Through DEA Malmquist dynamic analysis,the total factor production efficiency of six districts and counties,including ZN County,PL County,and LT District,is relatively low.The main factors are low efficiency in fund management and improper scale allocation.Based on the analytic results,we will continuously improve the quality of life of immigrants by strengthening management,optimizing project scale and types,implementing classified policies,and providing precise support.
