摘要为了能够高效地分类出农业保险承保与理赔业务连续数年变化差异大的险种,为相关从业人员深入研究农业保险的实施与创新提供决策支持与目标定位服务,以北京市政策性农业保险数据为依托,通过预先设定评价指标体系,研究经典决策树C4.5算法筛选目标险种的效果。结果表明,在排除政策影响的情况下,C4.5算法提高了对农业目标险种筛选的效率,可为相关从业人员开展重点险种的改革创新或开发新的服务业务提供参考依据。

AbstractIn order to effectively classify the different types of insurance in the agricultural insurance underwriting and claims settlement business for several years, to provide decision support and target positioning services for the relevant practitioners in-depth study of the implementation and innovation of agricultural insurance, we studied the effect of classical decision tree C4.5 algorithm in screening target insurance species by setting up an evaluation index system in advance based on Beijing's policy-oriented agricultural insurance data.The results showed that the C4.5 algorithm improved the efficiency of screening agricultural target insurance, and could provide references for relevant practitioners to carry out reform and innovation of key insurance or develop new service business.

農业保险是对农民生产风险的一种保障,我国农业保险起步较晚,但发展较快,全国各省均针对自身的地域特点开展了不同形式的农业保险业务,开发的险种各有不同,仅北京地区开展过的险种就多达59种(含已停售险种),每个新险种的产生都需要保险公司或科研机构投入大量智力资源来开发完成。一个好的农业险种必须能够平衡农户利益与保险公司利益,其效果发挥需要经过市场验证、(结合政策)调整、再验证反复进行。保险公司为了提高自己的服务质量,同时符合政府对农业保险实施精细化管理与市场的需求,需要不断地探索险种的改良与开发。
国内外学者对农业保险新技术或模型[1-3]、农业保险政策或发展模式[4-6]以及保险实施效果或评价进行了研究[7-8] ,但鲜有对历史险种的绩效评价方面的研究。……
