基于多分类离散选择模型的农产品安全风险评估研究

Agricultural Food Safety Risk Evaluation based on Multi-classification Discrete Choice Model

针对农产品安全风险评估问题,提出了一种基于多分类离散选择模型的风险评估方法。在建立农产品安全风险评估指标体系的基础上,建立有序多分类Logistic模型,给出了风险判别分析计算步骤。结合山东省出口蔬菜备案基地评价数据进行了实证研究。

For agricultural food risk evaluation, an assessment model based on multi-classification discrete choice model is proposed. On the basis of building an agricultural food safety risk evaluation index system, an ordered logistic model is put forward, and the calculation analysis steps are given. Finally, this method is illustrated by an example relevant to the agricultural product safety evaluation on export spinach sites which are put on records in Shandong province.
