| Abstract:A set of evaluation index system of foreign trade development was established based on the actual situation of Chinese foreign trade. After conducting pretreatment of all the evaluation indexes using principal component analysis, the author improves BP neural network with PSO to construct an evaluation model for foreign trade development.In specific application, the evaluation results derived from the model are more accurate, have some scientific and rationality. |
