Abstract:The non-point source pollution from the end of pig breeding industry has been more and more serious, which seriously affected the ecological environment and human health. Under this background, it is of great sense to conduct Choice Experiment, including “technology subsidy” “facility subsidy” and “income subsidy”, in order to analyze the willingness of 648 farmers to accept the policies in Shandong, Jiangsu, Fujian, Sichuan and Jiangxi Province. Result shows that farmers are more willing to accept “technology subsidy” and “facility subsidy”, in sharp contrast with the acceptance of “income subsidy”. Besides, it calculates EKC inflection point of pig income, divides the farmers into two halves and analyses the influence of different input of facility, technology and income on the manure treatment. In the end, it concludes that only when the it transforms to facility and technology, income has a significant impact on pollution treatment.
