Abstract: 【Objective】To explore the agricultural green production efficiency and the influencing factors constrained by the dual goals of “double carbon” and food security,in order to provide scientific support and policy references for improving agricultural green production efficiency and achieving the “double carbon” goals.【Methods】Taking the main grain producing area in China,Anhui Province,as an example,based on the panel data of 16 cities from 2011 to 2020,the DEA model,Malmquist index model and Tobit model were constructed to conduct static analysis and dynamic evaluation of agricultural green production efficiency from time and space perspectives,and analyze the key influencing factors as well.【Results】The comprehensive efficiency of agricultural green production in Anhui Province was 0.593,showing a spatial distribution pattern of high in the south and low in the north. The pure technical efficiency was 0.808,with a spatial distribution pattern of high in the middle and low on both sides. The scale efficiency was 0.731,with a distribution pattern of low in the middle and high on both sides. The agricultural green total factor productivity had been steadily improving,showing a spatial distribution pattern of high in the middle and low on both sides. Due to the varied degrees of resource redundancy and scale input in agricultural green production,the majority of regions did not reach optimal production efficiency levels. The area of cultivated land and agricultural mechanization could significantly improve the agricultural green production efficiency,while the proportion of urban population and disaster conditions could significantly reduce the agricultural green production efficiency. 【Conclusion】The overall level of agricultural green production efficiency in Anhui Province was not high,and there were regional variations. Cultivated land area and agricultural mechanization were the positive factors affecting agricultural green production efficiency.
