Farmers' response willingness to different mechanism of controlling agricultural non-point source pollution: a multi-dimensional social capital perspective

This paper built a multi-variate Probit model to analyze the impact factors to farmers’ responsive willingness to different mechanism of controlling agricultural non-point source（NPS） pollution by using survey data in Sichuan province，characterized farmers’social capital in four dimensions: social network，social prestige， social trust，and social participation by using factor analysis method. The three different mechanisms were restrictive policies，market mechanism and extension program. The results indicated that farmers’social capital significantly affected farmers’ response willingness. When government constructed and implemented the mechanism of controlling agricultural NPS pollution，the effects of social capital should be considered at the same time with the effects of governmental supervision，market and education mechanism.
