This paper presents a new concept: eco-economic system of plant protection. The component, structure and environment of this system together with its three subsystems, plant protection ecosystem, plant protection technical system and plant protection economic system, all discussed separately. Characteristics and functions of the system, together with ways and means of tackling governmental regulations and fiscal management are given detailed discussion.The farmer is one of the components in the plant protection economic system. In the second chapter of this paper, a qualitative approach was adopted to analyze farmers' behaviors during the course of plant protection processes. Factors influencing the plant protection behavior were looked at. A quantitative economic model was developed for the final analysis. A questionnaire survey was analyzed investigating the farmers' behaviors. Game theory was adopted to look at the ways that decisions were made and organizational approaches taken regarding the use of pesticides. It was concluded that when farmers cooperate in groups, decisions as to pesticide use is unified within the group, independence is maintained among the groups, with groups of fewer numbers using less pesticide, resulting in greater profits. In addition, strategies are presented for promoting cooperation. This research presents strategies for organizing the use of pesticides in ways to ensure the safety of the ecological environment.Chapter 3 presents the issue of pesticide market, plant protection equipment market, agri-product quality market and pesticide enterprises. The Chinese pesticide industry was reviewed particularly its effect on the use of resources, environmental pollution, ecological safety issues and the health of involved people and domestic animals. Clearly, changes were called for. Consequently, the issue of manufacturing pesticides combined with the efficient usage of resources was analyzed using game theory. The feasibility and validity of ways to aggregate efforts were proven. It also analyses the supply and demand of plant protection technological services. Factors that influence demand and supply were studied. The current new characteristics and requests from plant protection services in this country are described with associated extending administrative systems and socialized service organizations involved in plant protection analyzed. Results indicate that full development to supply themarket with a plant protection technical service will rely on a free management service enabling the cultivation of a multivariate market share.There are risks in controlling pests. Chapter 4 reviews some conceptions of risk. It presented conceptions of including natural risk, technological risk, service risk, marketing risk, managerial risk in plant protection eco-economic system. These are analyzed resulting in a comprehensive evaluation index system being established. The AHP-Fuzzy comprehensive evaluation method was applied to evaluate the risk of plant protection. Risk management strategies by the producers are discussed. Possibilities of loss due to regional pests are described. The distributing test procedure, losing risk interval and the method to calculate probability were designed and the effect of the probability in confirming an insurance rate was introduced. The losing risk of rice pest in Fujian Longyan city together with the risk probability distribution, losing risk interval and the corresponding probability were all demonstrated. Some integrated measures for decrease of risk are presented.The Government has a responsibility to optimize plant protection eco-economic system. Three aspects are discussed in Chapter 5: (i) the scope of what is regarded as purely public goods, semi-public goods, and private goods; what governs the supply of public goods; the elements of the market: supply and demand; rectification of the market: raise consumption and cultivate a socialized plant protection technical service market, (ii) At every level of plant production, protection measures must b...
