摘要: 为了促进农业保险公司客观、快捷地提供气象灾害的经济补偿,本文基于长序列的历史气象资料和花生种植面积、总产量和单产量数据,确定不同减产率范围下对应的连阴雨灾害指数临界值,建立连阴雨天气指数保险模型,设计出适用于研究区域的连阴雨天气指数保险产品。结果表明:依据连阴雨灾害指数,确定兰考县、虞城县、通许县的免赔额为0,开封县、民权县等6个县的免赔额为10%,睢县、郸城等4个县的免赔额为15%,淮阳、柘城等6个县的免赔额为20%,确定了不同区域的纯保险费率及保费,设计了农业气象保险指数合同。该天气指数保险产品采用客观的气象数据定损,操作性强,可有效转移花生生长气象灾害风险,促进农业保险的可持续发展。

Abstract:

To provide technical support for effectively improving the insurance company’s compensation for meteorological disasters, we employed longsequence meteorological dataset, planting area, total production, and yield per unit area of peanut to quantify the threshold for disaster indices of the continuous rain days corresponding to different yieldreduction rates, established continuous rain weather index insurance models, and designed insurance products of continuous rain weather index suitable to the study area. According to the continuous rain disaster index, the deductible amount was 0% in Lankao, Yucheng and Tongxu counties, 10% in six counties such as Kaifeng, 15% in four counties such as Suixian, and 20% in six counties such as Huaiyang. The pure insurance rates and insurance expenses in different regions were determined, and an agrometeorological insurance index contract was designed. The weather index insurance products adopt objective meteorological data to fix the loss and are very maneuverable, which can effectively transfer the risk of meteorological disasters during peanut growth and help agricultural insurance companies to provide economic compensation for meteorological disasters objectively and quickly.
