AB - Given the background of the rural population ageing, the reduced agricultural  non-point source pollution and the decreased agricultural carbon emission,  agricultural producer services, as an important bridge between small  farmers and modern agriculture, are an important path to ensure food  security and the green development of agriculture. Based on panel data of 31  provinces in China from 2003 to 2020, this paper uses Slack-based measure  model with undesirable outputs (SBM-undesirable model)to calculate the  agricultural ecological efficiency of 31 provinces. Furthermore, the  two-stage least squares, the panel threshold model and the spatial Durbin  model are used to empirically analyze the influence mechanism and the  spatial spillover effect of agricultural productive services on  agricultural ecological efficiency. The results show that agricultural  producer services have a significant non-linear impact on agricultural  ecological efficiency. Rural residents' income and per capita cultivated  land area can adjust the relationship between them. The two main ways for  agricultural productive services to improve agricultural ecological  efficiency are as follows: reducing undesirable outputs such as pesticides,  chemical fertilizers and plastic sheeting for agricultural use and improving  agricultural production efficiency. In addition, agricultural producer  services have a significant positive spatial spillover effect on  agricultural ecological efficiency, and the indirect impact elasticity of  spatial spillover is higher than the direct impact elasticity. Therefore, to  achieve food security and promote the sustainable development of  agriculture, it is necessary to vigorously develop agricultural productive  ser-vices through multiparty cooperation.
