Research On Risk Aversion, Participation In Cooperatives, And Adoption Of Green Prevention And Control Technologies By Vegetable Farmers

Chemical pesticides,as important means of production in agriculture production,have made great contributions to ensuring food security.However,with the development of agriculture modernization,higher requirements have been put forward for the quality of agricultural products,but the use of traditional chemical pesticides has seriously damaged the safety of agricultural production and the quality safety of agricultural products.The abuse of chemical pesticides by farmers in China is very common,and the negative externality of chemical pesticide use has become very obvious.As an effective substitute for chemical pesticides,green control techniques provides an effective way to achieve pesticide reduction control,but use of green control techniques is low,and there are still many difficulties in large-scale application.Farmers' risk aversion is considered to be an important reason for the low level of promotion and application of green control techniques.However,in theory,guiding farmers to participate in cooperatives is an effective way to alleviate the effect of farmers' risk aversion on inhibiting their adoption of green control techniques.It provides a new perspective for solving the problem of the low degree of popularization and application of green control techniques caused by farmers' risk aversion.Based on survey data from a total of 640 vegetable farmers in Shandong and Henan provinces,this paper uses experimental economics approach to rigorously measure the degree of risk aversion of vegetable farmers,and uses the endogenous switching probit model to reveal the degree of risk aversion of vegetable farmers to their cooperatives and the degree of risk aversion of vegetable farmers,and vegetable farmers' cooperative participation on their green control techniques' adoption behavior.Furthermore,the simplified equations of the switching equation and the outcome equation in the endogenous switching probit model were established,and it was verified whether the vegetable farmers' participation in cooperatives could help alleviate the inhibitory effect of their risk aversion on green control techniques' adoption.The results show that: First,most of the sample farmers are risk-averse.Second,the head is male,the higher the education level,and the higher the awareness of the importance of vegetable quality,the more he will help vegetable farmers to participate in cooperative,the larger the age of the head and the family planting scale,and the higher the proportion of off-farm income,the more it will prevent vegetable farmers from participating in cooperatives;the head is women,the higher the education level,the larger the planting scale,the better the family financial situation,and the higher the awareness of the importance of vegetable quality,the more they will increase the adoption of green control techniques,and the greater the number of family labor,the more difficult it is for them to adopt green control techniques.Third,the degree of risk aversion of vegetable farmers has a significant positive impact on their participation in cooperative,and a significant negative impact on their adoption of green control techniques.Fourth,the participation of vegetable farmers in cooperatives will not only promote their adoption of green control techniques,but also alleviate their risk aversion to inhibitory effect of adoption of green control techniques.Based on the above research conclusions,we put forward policy suggestions on how to weaken the potential risks of farmers' adoption of g green control techniques and how to speed up farmers' participation in cooperatives,so as to contribute to the large-scale promotion and application of green control techniques.
