本研究旨在探討高中職校長資訊使用環境對資料導向決策之影響，剖析不同背景變項與學校變項知覺高中職校長資訊使用環境與資料導向決策的差異情形，探討資訊使用環境對資料導向決策的關係，並根據研究結論，提出建議。為達上述研究目的，本研究採用問卷調查法，以全國513所高中職校長為研究對象，回收有效問卷272份。本研究獲得以下結論：一、高中職校長知覺資訊使用環境和資料導向決策為中高程度。二、不同教育程度之校長知覺資訊使用環境及運用資料導向決策上，具有顯著差異。三、不同學校類別之校長知覺資訊使用環境上，具有顯著差異。四、不同學校歸屬之校長知覺資訊使用環境及運用資料導向決策上，具有顯著差異。五、本研究建構之模式經過結構方程模式檢定獲得支持，高中職校長資訊使用環境對資料導向決策具有正向顯著的影響。

This study aims to discuss the effects of the information use environment of high school principals on data-driven decision-making. This study analyzed variables with different backgrounds and school-related variables to perceive the different situations of the information use environment of high school principals and their data-driven decision-making, and discussed the relationship between information use environment and data-driven decision-making. To achieve the research purposes, the study adopted questionnaire survey, and treated 513 high school principals as the research subjects. 272 effective samples were retrieved. The results are as follows: (1) The perception level of the information use environment of the principals and their data-driven decision-making are medium-high. (2) Among the principals with different educational levels, there are significant differences of the perception of the information use environment of the principals as well as their application of data-driven decision-making. (3) Among the principals of different school types, there are significant differences of the perception of the information use environment of the principals. (4) Among the principals from different schools, there are significant differences of the perception of the information use environment of the principals and their application of data-driven decision-making. (5) The study was verified by Structural Equation Modeling and the effects of the information use environment of the high school principals on data-driven decision-making appear to be positive and significant.
