基于DEA模型的移民后扶资金使用效率研究

Research on the Use Efficiency of Post Resettlement Support Funds Based on DEA Model

大中型水库移民后扶资金关系到移民的切身利益,对移民安置区和库区的社会稳定具有十分重要的意义。本文基于2021年GX自治区13个样本县(市、区)的后期扶持资金使用情况和实施效果,利用DEA(数据包络分析法)模型对后扶资金使用效率进行测算,并进行效率相关因素的分解研究。研究结果表明:各县后扶资金的纯技术效率值较好,综合效率水平主要受规模效率的影响,需要进一步优化分配规模以改善资金投入中的冗余问题。松弛变量计算结果与实际情况相匹配,可以以此作为调整资金使用方向的有效依据。由数据分析可知,提升后扶资金使用效率的关键点在于:以效率评价结果为导向探寻后扶资金使用过程中的堵点;调整和优化后扶资金的分配规模和使用方向;结合移民实际需求进行规划。

The post-relocation support funds for large and medium-sized reservoirs are related to the immediate interests of the immigrant,and are of great significance to the social stability of the resettlement areas and the reservoir areas.Based on the use and implementation ef⁃fects of the post-support funds in 13 sample counties(cities,districts)in the GX Autonomous Region in 2021,this paper uses the DEA model to measure the efficiency of post-support funds and analyze related factors.The research results show that the pure technical efficiency value of the post-support funds in each county is good,the overall efficiency is mainly affected by the scale efficiency,and the allocation scale needs to be further optimized to improve the redundancy problem in capital investment.The calculation result of the slack variable matches the actual situation,which can be used as an effective basis for adjusting the direction of capital use.From the data analysis,it can be seen that the key points to improve the use efficiency of post-support funds are:to explore the blocking points in the use of post-support funds based on the efficiency evaluation results,to adjust and optimize the distribution scale and usage direction of post-support funds,and to make a reasonable layout based on the actual needs of immigrants.
