摘要
应用随机试验熵的概念，选取反映棉花产业发展状况的一些指标，计算我国产棉主要省份2000～2007年的相对熵值，并对南方、北方规模产区各省市棉花产业区域不均衡发展状况进行了分析。
The concept of entropy in the random trial is applied in the study and the relative entropy is used to analyze the unbalance development of cotton industry in northern and southern of China from 2000 to 2007. Some indices reflecting the development of cotton industry are chosen to calculate the relative entropy. At the same time the area unbalance development of cotton industry is studied on the basis of the relative entropy.
