Measurement and Spatial-temporal Differentiation of Rural Financial Support Efficiency in Major Grain-producing Areas of China
摘要
Abstract
Improving the rural financial support for agricultural production in the main grain-producing regions of China is an important focus to enhance the grain production capacity in these regions and ensure national food security.To optimize the allocation of financial resources in grain-producing regions and enhance the rural financial support efficiency.Based on the panel data of 13 grain-producing regions in China from 2013 to 2022,the super-efficiency SBM model and DEA-Malmquist model were used to measure the rural financial support efficiency of Chi-na's grain-producing regions statically and dynamically,and the Kernel density estimation method and Dagum Gini coefficient were used to measure the spatial and temporal heterogeneity and source of rural financial support efficiency in grain-producing regions.The research results show that the comprehensive technical efficiency of rural financial support in China's grain-producing regions was low in 2013,2022,and the rural financial support efficiency has been increasing at an average rate of 1.6%per year.At the same time,the efficiency evolution has an in-termittent trend of bifurcation and the trend has been strengthening in the measurement period,with low efficiency dominating in the process of bifurcation.The kernel density curve of the three river basin grain-producing regions shows a clear multi-peak feature in the measurement of the early and middle periods,and the main peak value reaches the highest,indicating that the efficiency division problem in the river basin is rela-tively serious during this period.The average Gini coefficient of overall efficiency in the measurement period is 0.161 3,showing significant spatial non-equilibrium,and the river basin difference is the main reason for the significant spatial non-equilibrium in the measurement period.关键词
