摘要
从基础设施、资源利用、财政支出、民众受益4个方面构建我国公共图书馆发展水平评价指标体系,采用基于实数编码加速遗传算法优化的投影寻踪模型,对30个省(除西藏)公共图书馆发展水平进行的实证研究表明,我国省域公共图书馆发展在地理上存在东、中、西阶梯分布状态。东南沿海地区形成以上海为中心的图书馆发展水平高值集聚,在这个高值集聚中心以南、以西形成以福建和四川为中心的异质性突出的区域。在我国西部地区,形成以甘肃、宁夏、新疆为中心的低值集聚中心。
The study chooses public libraries in 30 provinces(except Tibet) as the research object, from four aspects, infrastructure, resource utilization, financial expenditure, and the public benefit to establish a public library development level evaluation index system. Employing Real-Coding-Based Accelerating Genetic Algorithm and Projection Pursuit Model (RAGA-PP), the emperical study shows provincial public libraries present ladder-like spatial distribution. Southeastern coast area forms library with high development level agglomeration cored by Shanghai. In the south and west of the agglomeration area, a heterogeneity area is appeared cored by Fujian and Sichuan. In the western, low agglomeration area is formed cored by Ningxia and Xinjiang.
