应用数学模型的图书馆指标对比实证分析

Comparative Analysis of Library Evaluation Index Based on Mathemati-cal Model

对国际大都市图书馆之间的比较,通常是将指标的绝对数值直接对比。由于各城市的人口数量不同,造成这种比较具有一定误差。为解决这一问题,文章采用数学建模方法,通过基准数据建立模拟方程,对应不同人口数量计算出相应的基准数值,再以实际数值与基准数值的偏差百分比作为对比依据。根据此方法,对上海与其他国际大都市的图书馆指标进行比较分析,表明上海在图书馆人均藏书和人均借书指标上与纽约、东京等国际大都市存在一定差距。

Comparative analysis of absolute numerical index is always used in the comparison of the international metropolitan libraries. However,due to the differences in population,this method has a certain error. In order to solve this issue, this paper introduces mathematical models to create a simulation equation based on the benchmark data. Benchmark values are calculated according to different populations. Then deviation percentage between the actual value and the benchmark value is used as the grounds for comparison. Based on this approach,the author does a comparative analysis on the indexes of metropolitan libraries in Shanghai and other international cities. Results show that Shanghai is still lower than the other international cities such as New York and Tokyo in per capita of library collection and per capita borrowing of books.
