As a special production factor,chemical pesticides can not only prevent diseases and insect pests,protect the output of agricultural products,but also reduce labor input.As the microcosmic body of the agricultural society of our country,the decision-making behavior of their production has a direct influence on the safe production of our agricultural products.Because of the huge role of the pesticide in the production,the agricultural producers in our country rely more and more on the application of chemical pesticides in the process of production and management,and even unreasonable increase the application of pesticides quantity.As a necessary food for daily life,vegetables occupy an irreplaceable position.The development of protected vegetable industry not only alleviated the imbalance between supply and demand of vegetables in different regions,but also contributed greatly to the increase of farmers' income.But it is precisely because the facilities of vegetable planting conditions are more prone to diseases and insect pests,so many facilities vegetables have to use more pesticides in the process of planting.Therefore,it is necessary to sort out the current characteristics of the behavior of the vegetable farmers in the process of production,determine whether there is a decision error behavior in the process of vegetable farming,and analyze the key factors that affect the choice behavior of the vegetable farmers,and propose a policy combination to optimize the decision-making behavior in the process of vegetable farming,and change the supply side to the agricultural supply side.Under the background of leather industry,it is of great theoretical and practical significance to improve the quality of vegetable supply,promote the safe production of agricultural products and the modernization of agriculture.In this paper,the decision-making behavior of pesticide application in the production process of plant pepper growers is taken as an example.The production decision-making behavior and the concept of marginal productivity of pesticide are fully defined.The present situation of the cost and income of the vegetable farmers in the production decision,the marginal production rate of agricultural pesticides and the decision behavior of the farmers in the pesticide application are completely combed.Based on the research content of influencing factors,and based on the theory of agricultural producer's behavior plan,the theory of profit maximization,the theory of risk aversion,and so on,256 vegetable peppers in Zhangjiakou,Hebei,China,were taken as samples to describe the present characteristics of the application behavior of the samples of the samples of vegetable farm pesticides.By introducing the standard C-D production function,the Exponential distribution and the damage control model of the Weibull distribution(Damage Control Model),the marginal productivity of the agricultural pesticide is calculated and the behavior of the vegetable farmers is judged by the excessive application of pesticide.On the basis of this,Probit regression model and OLS regression model were applied to further explore the significant factors that affect vegetable farmers' pesticide application behavior.This study found that the marginal productivities of vegetable farmers measured by the standard C-D production function and the damage control model were all close to zero,indicating that the farmers in the sample area had excessive pesticide application.There are three main types of behaviors that affect vegetable farmers' over-application of pesticides,namely,individual characteristics of farmers,government or organizational factors,and the cognitive factors of vegetable farmers on pesticides.Through analysis,we learned that we have joined professional vegetable cooperatives and participated in training on pesticide application.Accepting the government to carry out pesticide residue detection,taking into account safety intervals,and vegetable farmers who believe that large-scale application of pesticides will have an impact on the environment,the occurrence of over-application of pesticides is smaller,but the higher the degree of risk aversion,the greater the possibility of farmers.Based on this,this article draws the policy inspiration of promoting awareness and green prevention and control,making overall plans for both agricultural insurance and agricultural subsidies,vigorously promoting agricultural production services,and strengthening government supervision and information sharing protection.
