Measurement and Spatial Distribution of Agricultural Green Production Efficiency in Major Grain Producing Areas under the Dual Carbon Target
Based on the panel data of agricultural inputs and outputs in China's main grain-producing areas from 2003 to 2022,a panel three-stage DEA model is applied to measure the agricultural green production efficiency of the main grain-producing areas,and the spatial distribution of the agricultural green production efficiency in the region is analyzed hierarchically.It is found that,after removing the interference of environmental factors and random errors on the efficiency values,the increase of GDP per capita and disposable income per capita are conducive to the improvement of agricultural green production efficiency,and the increase of natural disaster-affected area hinders the improvement of agricultural green production efficiency.Further analyses found that the comprehensive technical efficiency and scale efficiency of agricultural green production in the main grain producing areas both show a spatial distribution trend of low in the north and south and high in the middle,and the pure technical efficiency values of agricultural green production are all relatively high and concentrated in spatial distribution.In order to further enhance the efficiency of agricultural green production in the main grain-producing areas and optimize its spatial distribution pattern,countermeasures are proposed to optimize the investment of financial funds for agricultural support;encourage new agricultural management main bodies to operate on an appropriate scale;and differentiate initiatives to enhance the efficiency of agricultural green production and narrow the gap in regional agricultural green development.
