Residents' Preferences to Public Library Analysis for

本研究试图从根本上了解在快速变化的ICT环境下，居民对公共图书馆服务的偏好模式。本研究包括三个部分：对470名茨城县图书馆访客的电脑访谈与公共图书馆互联网服务的适应性联合分析（ACA）、筑波市居民对公共图书馆服务六个方面的偏好调查，以及在第二项研究基础上修订的成田市居民调查。我们的实证结果可以总结为：1)使用互联网的能力和访问目的导致“工作人员协助”和“网站限制”的平均重要性不同，而“隐私”通常被认为是主要属性。根据这些用户的偏好，讨论了公共图书馆网络服务计算机的首选位置和环境。建议应明确目标部分，以考虑到不同用户的不同偏好。2)图书馆使用者与非使用者的偏好模式基本相似，但非使用者对参考咨询服务和物理环境的评价更为重要。社会经济变量和图书馆使用情况对居民偏好差异的描述无效。3)利用层次Bayse估计方法，我们发现居民可以分为三类：工作利用、阅读利用和日常生活利用。互联网的使用会显著影响人们的偏好，而传统媒体如电视和书籍/杂志的使用则不会。

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.
