基于三阶段DEA模型的珠江-西江经济带财政支农支出效率评价

Efficiency Evaluation of Fiscal Expenditure for Agriculture in Pearl River-Xijiang Economic Belt Based on Three Stage DEA Model

论文基于三阶段DEA模型测度分析珠江-西江经济带11地市2009-2018年的财政支农支出效率。结果表明:多数地市效率值与完全有效存在差距,市域差异程度相对较大;外部环境因素对财政支农支出效率均呈现显著正相关关系;基于SFA模型回归将各地市置于同等假定外部环境下,11地市的财政支农支出效率均出现下降;各地市可依据自身效率特征,基于投入规模、资金管理等方面提升资金支出效率。

Based on the three-stage DEA model,this paper measures and analyzes the efficiency of fiscal expenditure for agriculture in 11 cities of the Pearl River-Xijiang economic belt from 2009 to 2018.The results show that:there is a gap between the efficiency value of most cities and the total efficiency,and the degree of city difference is relatively large;external environmental factors have a significant positive correlation with the efficiency of fiscal expenditure for agriculture;based on the SFA model regression,the efficiency of fiscal expenditure for agriculture in 11 cities decreases under the same assumed external environment;each city can improve the efficiency of capital expenditure based on its own efficiency characteristics,investment scale and capital management.
