基于余期望系数的公共图书馆馆藏资源区域差异研究

On the Regional Difference of Public Library Collection Based on Surplus-Expectation Coefficient

论文将全国公共图书馆人均拥有藏书量作为代表性的指标,选取1980至2005年全国31个省市自治区的统计数据,采用余期望系数模型研究了我国自东向西三大经济地带公共图书馆各自的余期望系数、组间差异、组内差异以及全国范围内总的余期望系数等变量。研究发现了我国公共图书馆人均拥有藏书量的差异特点,分析了其变化趋势,提出了改善我国各地区公共图书馆差异状况的思路。

Selecting public library collection per capita of 31 Chinese provinces as the representative index during the 25 years from 1980 to 2005, this paper studies on four variables： surplus-expectation coefficient of per economic zone, difference between and within econom- ic zones, and the whole surplus-expectation coefficient of Chinese Public Library collection. As a result it founds out the characteristics of Chi- nese Public Library collection, and analyses their changing trend, puts forward train of thought to ameliorate the difference condition of Chinese pubic library.
