臺灣博碩士論文加值系統

從國土規劃與研究之角度而言，國土資訊系統儼然已成為政府及民間不可或缺之重要決策工具。然就研究者目前使用而言，仍存在資訊技術自主性不足、基本數值化資料建立、更新緩不濟急等諸多課題。然而在以往研究中，對於使用者採用地理資訊系統行為之潛在因素間之共變關係多欠缺探討，而結構方程模式能剖析複雜之關係現象與構念，並可衡量一系列線性結構模式之未知係數，以檢驗理論模式的整體適切性。爰此，本研究嘗試以結構方程模型探討地理資訊系統使用者特性為研究焦點。研究乃透過問卷調查與結構方程模式，從使用者對地理資訊系統之認知、有用性、易用性與使用意願來驗證技術接受模式，並經由結構方程模式來度量及檢驗上述各變數之因果關係以衡量模式之合適程度。本研究將初始模型中的各構面問項經由信度檢定與項目分析將項目總分相關係數小於0.7的3個問項予以刪除，再透過常態性假設將未達顯著的7個問項予以刪減，使得問卷題項從原先的62題減為52題，並將該初始模型經由結構方程模式中的最大概似法來進行模型校估，最後透過適配指標來作為模型修正之參考依據，進而得到初步完整的模型架構。希冀研究成果有助於地理資訊系統相關政策推動之參考。

From the national geographical planning and research point of view, the National Geographical Information System has already become an indispensable and essential decision-making tool for both the government and the public. But seen from researchers’ current usage of the system, there are still a lot of pressing problems such as the lack of autonomy in information technology, and those concerning the build-up and update of basic digital data. In the past studies, however, little discussion has been made on the covariance relation between potential factors of users’ behaviors of using the Geographical Information System (GIS). While the Structural Equation Model (SEM) can be used to analyze the complicated relational phenomena and concepts, and to assess the unknown of a series of linear structural models, the overall relevance and adequacy of the theoretical model is then verified. Thus, this study tries to explore and focus on users’ characteristics of the GIS with the SEM approach. The study is conducted through questionnaire survey and SEM, by which the Technology Acceptance model is verified against users’ awareness of the GIS, their idea on its usefulness, ease of use and their willingness to use it. And the causal relation between the above variables is assessed and verified through SEM, thereby the relevance and adequacy of the model is assessed. All perspective items in the initial model undergo reliability test and item analysis, and the three items with corrected item-total correlation smaller than 0.7 are deleted, and then the seven items with significance less than 7 on normality assumption are also deleted. The number of items in the questionnaire hence reduces from the original 62 to 52 questions. The initial model is then edited and assessed with the Maximum Likelihood (ML) method in SEM. Finally, the model is amended based on the reference of the relevance and adequacy index, and hence a preliminarily comprehensive model framework is completed. It is expected the research result will form a helpful reference for promoting policies related to the GIS.
