摘要
Abstract
The non-radial and non-angular super-efficiency SBM model was used to measure the agricultural eco-efficiency of 30 provinces and cities in China from 2007 to 2020.The results showed that Chinese agricultural eco-efficiency showed an upward trend after a short fluctuation,and the value of Chinese agricultural eco-efficiency increased in northwest,central and southeast regions.The level of economic development and mechanized agriculture will have a negative impact on Chinese agricultural eco-efficiency.Farmers' economic conditions,agricultural structure and investment in agricultural fixed assets can promote the improvement of agricultural eco-efficiency.The effect of environmental governance on the agricultural eco-efficiency in the south-east and central regions is significant,but the effect is in the opposite direction;the agricultural eco-efficiency in the north-west region is only related to the level of local economic development and farmers' economic status.关键词
