Abstract Farmers use fewer amount of pesticide when they produce agricultural products for themselves, but use more when agricultural products are to be sold to the market. This paper refers to this phenomenon as“one family, two systems”. A multi-task principal-agent model is built to analyze the cause of “one family, two systems” under thousands of households with non- organized small scale farmers. Then through the analysis of a sample of 616 farmers from several provinces, it proves that Cooperatives?are effective?in improving this situation. The results show that the different uses of agricultural products, farmers’ educational level, whether there is a teacher or a doctor in the family, the awareness of pesticide hazards cannot eliminate the phenomenon of “one family, two systems”. The suggestions of this paper are to cultivate the new agricultural management subject and to develop the agricultural cooperative organization.
