Features: This book discusses the adoption of Integrated Pest Management (IPM) using economic methods. It analyzes the decision-making behavior of individual producers adopting IPM through an economic threshold model, uses external costs as a basis for policy-making on IPM projects or related policies, and conducts an empirical analysis of farmers' willingness to pay for environmental and health protection. It identifies the main reasons for the insufficient adoption of IPM and systematically elaborates on how to internalize externality factors in the process of pest management. The approach to solving the problem of excessive pesticide use is to have the government intervene in the market while minimizing government failures. The management of pesticides includes forms such as global management, regional management, and government management. The management methods of governments in different countries are divided into two major categories: direct intervention and economic incentives. The implementation and enforcement costs of command-and-control methods are often high, and efficiency losses may arise due to information gaps or one-size-fits-all standards. Economic incentives, represented by Pigouvian taxes, often exhibit high economic efficiency, but their effectiveness is also constrained by factors such as information costs and the low price elasticity of pesticide use. When selecting pesticide management methods, it is necessary to consider characteristics such as the slope of marginal benefit and marginal cost curves, the heterogeneity of the target population for management, and non-point source pollution, and to make flexible choices accordingly. In international management, the discussion primarily focuses on controversial issues such as the impact of pesticide residue management on international competitiveness, the establishment of unified standards for pesticide residue management, and the trade of genetically modified products.
