Abstract:
The efficiency of vegetable production environment is an important indicator for measuring the coordination between vegetable production and resource environment.After comparing and analyzing the environmental efficiency of vegetable production in different regions of China from 2012 to 2021 using the super efficiency SBM model，it was found that the environmental efficiency and pure technical efficiency of vegetable production in Northeast China had always been ahead of other regions，while the technical efficiency of vegetable production scale in the central region was the highest in the country.From the perspective of the average redundancy of input-output in vegetable production nationwide，according to the redundancy rate of production factors，it was arranged in descending order,labor input，mechanical power input，water input，comprehensive resource input，and land input.The unexpected output redundancy rate was as high as 44.85%，and the expected output of no vegetables in the country is insufficient.After using the ML index analysis method to analyze the total factor productivity of vegetable production environment in China，it was found that the total factor productivity of vegetable production environment in the country was all greater than 1，and overall was relatively stable.Based on the research findings，several suggestions have been proposed to improve the environmental efficiency of vegetable production in China.
