中文摘要：

依我国各省（市、自治区）报纸种数、报纸总印数和报纸总印张数等三个指标1986-2006年的数据,构建这一时期各指标相对熵的时间序列。应用ADF检验求时间序列单整阶数并做出分析,应用方向数据统计探讨报纸总印张数相对熵的周期变化。

英文摘要：

Three indicators including the total types, the total copies and the total pages which reflect the regional newspaper publication development of China＇s 31 provinces, autonomous regions or municipalities from 1986 to 20（16 are chosen. The paper builds three time series on the relative entropy of above indicators. Utilizing Augmented Dickey-Full （ADF） Test the paper testifies the integrated order of three time series and analyzes the trend of the regional newspaper publication development in China. In the end the cyclical characteristic of the relative entropy of the total pages is illustrated by applying directional statistics.
