摘要
农业保险制度不仅是农业保障体系中重要组成部分,而且已成为国际上最重要的非价格农业保护工具之一。但长期以来,我国农户的农业保险参与率较低且不稳定,造成农业保险几乎处于市场失灵的危险境地。本文把所研究的农业总人口分为三类:不了解农业保险且没有买农业保险的人群;了解农业保险但没有买农业保险的人群;了解农业保险且买了农业保险的人群。建立基于微分方程组的数学模型,探讨了系统平衡点的存在性、稳定性并进行了数值模拟和讨论。
Agricultural insurance is not only important in the agricultural support system, but also it has become one of the most important international non-prices agricultural protection tools. But the rate of Chinese farmers participating in agricultural insurance is low and unstable, resulting in the market failure in the agricultural insurance. In this paper, the study by the agricultural population is classified into three categories: The group of lack of understanding of agricultural insurance and no buying agricultural insurance; The group of understanding of agricultural insurance But no buying agricultural insurance ; The group of Understanding of agricultural insurance and have bought agricultural insurance. We establish the differential equations model, discuss the existence and stability of the system balance, and conduct the numerical simulation.
