| Abstract: | 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. |
