摘要
水库移民后扶资金的使用效率会直接影响水库移民的生活条件和生产水平,如何选择合适的水库移民后扶资金使用方向及比例,以达到水库移民后扶资金使用效率的最大值,是当下亟须解决的难题。本文基于2021年GD省15个样本县(市、区)的水库移民后扶资金使用情况和实施效果,使用DEA模型对水库移民后扶资金使用效率进行测算;同时将环境因素纳入考虑范围,使用Tobit回归模型分析影响资金使用效率的环境因素。结果表明:①样本县的水库移民后扶资金使用效率相差较大,其中纯技术效率值较好,规模效率成了影响综合效率的主要因素,需要优化规模配置改善投入冗余;②在影响资金使用效率的环境因素中,样本县经济发展水平、常住人口城镇化率和开放程度的提升有助于水库移民后扶资金使用效率的提升,而第三产业增加值对水库移民后扶资金使用效率提升并无显著促进作用。
How to choose the direction and proportion of the use of reservoir migrants’support funds to achieve the maximum efficiency of the use of reservoir migrant support funds is a difficult problem to be solved urgently.Based on the use and implementation effect of reservoir mi⁃gration support funds in 15 sample counties(cities and districts)in Guangdong Province in 2021,this paper uses the DEA model to calcu⁃late the efficiency of reservoir migration support funds.At the same time,environmental factors are taken into account,and the Tobit regres⁃sion model is used to analyze the environmental factors affecting the efficiency of capital use.The results show that:①The efficiency of the use of reservoir resettlement support funds in the sample counties varies greatly,among which the pure technical efficiency value is better,and the scale efficiency has become the main factor affecting the comprehensive efficiency,and it is necessary to optimize the scale alloca⁃tion to improve investment redundancy;②Among the environmental factors affecting the efficiency of capital use,the improvement of the economic development level,urbanization rate and openness of the permanent population in the sample counties contributed to the improve⁃ment of the efficiency of the use of reservoir migrants’support funds,while the added value of the tertiary industry did not significantly pro⁃mote the efficiency of the use of reservoir migrants’support funds.
