Residents' Preferences to Public Library Analysis for

本研究旨在了解资讯科技快速发展下，市民对公共图书馆服务的偏好模式。本研究包括三个部分：对茨木县立图书馆的470名访问者进行了计算机访问，并对公共图书馆的互联网服务进行了适应性联合分析（ACA）;在筑波市进行了关于公共图书馆服务六个方面的居民偏好调查;实证结果发现：1）不同的网路使用能力与访问目的，会导致“工作人员协助”与“网站限制”的平均重要性不同，而“隐私”则普遍被视为主要属性。根据这些用户的偏好，我们讨论了公共图书馆互联网服务的计算机的最佳位置和环境。2）图书馆用户与非用户的偏好模式基本相似，但非用户对参考咨询服务的评价和物理环境的影响更大。社会经济变量和图书馆利用率不能有效描述居民的偏好差异。3）采用分层贝叶斯估计方法，发现居民可以将图书馆利用分为工作利用、阅读利用和日常生活利用三类。互联网的使用影响偏好显着，虽然传统的媒体使用，如电视和书籍/杂志没有。

This research attempts to gain a fundamental knowledge of residents' preference pattern in public library services given the rapidly changing environment of ICT. Our research consists of three part : computer based interviews with 470 visitors to Ibaraki Prefectural Library and the adaptive conjoint analysis (ACA) regarding internet service in public library, survey of residents preference concerning six aspects of public library services conducted in Tsukuba City, and survey of Narita City residents revised from the second research. Our empirical results can be summarized as follows :1)The ability in using the internet and the purpose of the visit lead to different results in the average importance of "staff assistance" and "site restrictions", while "privacy" was commonly regarded as a principal attribute. Based on these users' preferences, we discussed preferable location and environment for computers of the internet service in a public library. It is suggested that the targeted segment should be clarified to account for distinct preferences of various users.2)The preference pattern between library users and non users are almost similar although non users evaluate reference service and physical environment are more important. Socioeconomic variables and library's usage are ineffective for describing difference of residents' preferences.3)Using hierarchical Bayse estimation method, we have found that the residents can categorize to three groups : utilization for work, utilization for reading, and utilization for daily life. The usage of internet affects preferences significantly although traditional media usage such as television and books/magazines don't.
