Residents' Preferences to Public Library Analysis for

本研究试图了解在资讯科技快速变化的环境下，市民对公共图书馆服务的偏好模式。本研究由三部分组成：对茨城县图书馆470名访客的计算机访谈和对公共图书馆互联网服务的自适应联合分析(ACA)，对筑波市公共图书馆服务六个方面的居民偏好调查，以及在第二项研究的基础上修订的成田市居民调查。我们的实证结果可以概括如下：1)使用互联网的能力和访问的目的导致“工作人员协助”和“站点限制”的平均重要性不同，而“隐私”通常被认为是主要属性。基于这些用户的偏好，我们讨论了公共图书馆网络服务计算机的最佳位置和环境。2)图书馆用户和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更重要，物理环境更重要。社会经济变量和图书馆使用情况不能有效地描述居民的偏好差异。3)采用多层次贝叶斯估计方法，将居民分为三类：工作利用、阅读利用和日常生活利用。互联网的使用极大地影响了人们的喜好，尽管电视和书籍/杂志等传统媒体的使用不会影响人们的喜好。

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.
