Abstract
Using the relational analysis method of gray system theory ,this paper analyzed the main factors w hich affected Shanghai copper futures price in 2012 ,and selected out the main in-fluencing factors .The input vector was the main influencing factors ,and the output was the ref-erence price ,the BP neural network forecast model was established between Shanghai copper fu-tures price and the main influencing factors .The empirical results showed that this method had a high prediction precision and strong practicality .关键词
