中文摘要：

构建农户农药施用行为的选择模型,运用环渤海湾与黄土高原两大苹果优势产区635个样本农户的面板数据,从高毒农药施用和农药投入2个维度刻画农户农药施用行为的规律及其决定因素.研究表明：农户农药施用行为区域差异显著,环渤海湾地区的高毒农药施用概率与农药投入水平均高于黄土高原地区;高毒农药施用与农药投入的农户决策机理及其决定因素具有差异;其中,高毒农药对绿色农药的低成本经济替代是导致农户施用高毒农药的主要原因.提出政策建议：政府应进一步加强食品安全规制,引导农户规范施用农药,推进产业组织建设,促进绿色农药技术创新,完善市场机制建设,加强农户教育,重视技术推广与示范.

英文摘要：

This paper builds a selection model of farmers＇ behavior of application of pesticides and uses 635 panel data of samples of households from two main apple planting areas of loess plateau and area around the Bohai gulf for estimation. It describes the laws in farmers＇ behavior of application of pesticides and its determinants from two dimensions, namely the application of high toxic pesticides and the pesticides input. Research reveals a significant regional difference in farmers＇ behavior of application of pesticides, with the application of high toxic pesticides and pesticide input levels in the area around the Bohai gulf higher than those in the loess plateau region in average＇ and the mechanism of decision-making and determinants vary in two regions too. It further shows that the low cost of high toxic pesticides highly explains farmers＇ behavior in abandoning the green pesticides. It is proposed that the government should enhance the rules and regulations for food safety, induce farmers to apply pesticides normally, elevate the construction of industrial organizations, facilitate the innovations in green pesticide technology, perfect the construction of market mechanism, strengthen education to popularize new agricultural technology among farmers.
