中文摘要:基于上海财经大学千村调研的数据，建立damage-abatement生产函数模型，实证检验了粮食生产中各种要素对农药施用行为的影响。研究表明：市场收益、政府介入及农户特征这三类因素均会对农药施用产生影响。进一步分析农户的政策诉求显示：使用农药强度高的农户对技术指导的诉求反而低于使用农药强度低的农户，这种逆向选择进一步增加了农药滥用治理的难度。

Economic Analysis of High Intensity Application of Pesticides in Grain Production in China

Abstract:Based on survey from thousand villages by Shanghai University of Finance and Economics, the damage-abatement production function model is established, and the effects of various factors on pesticide application behavior in grain production are empirically tested. The study shows that the three factors such as market income, government intervention and farmers' characteristics all affect the application of pesticides. Based on this, we further analyze the policy demands of farmers, and get the conclusion: farmers with high pesticide intensity were less satisfied with technical guidance than those who used low pesticide intensity. This adverse selection further increases the difficulty of pesticide abuse governance.
