以科技接受模型探討自行車衛星導航系統之使用者使用行為

目前國內學者對於自行車的研究，大多集中於運動休閒及觀光遊憩等方向，而探討自行車騎士對於特定科技系統的接受度研究卻非常稀少，因此本研究結合電腦自我效能及科技接受模型， 建立一個影響自行車騎士使用自行車GPS導航系統的研究架構。本研究於2012年12月至2013年02月，針對參與臺灣自行車環島運動協會所舉辦環島運動之第67梯次至第70梯次車友，進行立意抽樣調查，總共發放244份問卷，最終獲得有效問卷239份(有效問卷率為97.95%)。

本研究以SPSS與AMOS統計軟體作為統計分析工具，檢驗模型之配適程度及探討各變數之間的相互關係。研究結果如下：1、模型期望共變異數矩陣與樣本共變異數矩陣無差異；2、電腦自我效能對知覺有用性未達顯著正向影響；3、電腦自我效能對知覺易用性達顯著正向影響；4、知覺易用性對知覺有用性達顯著正向影響；5、知覺有用性對使用態度達顯著正向影響；6、知覺易用性對使用態度達顯著正向影響；7、使用態度對行為意圖達顯著正向影響；8、知覺有用性對行為意圖達顯著正向影響。

根據研究結果，建議自行車GPS導航系統廠商，產品除著重於簡單易懂的特性，亦要使自行車騎士能感受到該系統有益於騎乘規劃，如此才能提升對於該產品的喜好程度與使用意願。

Current domestic studies on bicycles have generally focused on sports, leisure, tourism, and recreation. There have been few studies that emphasized the extent to which cyclists accept certain technology systems. Thus, computer self-efficacy and technology acceptance model are combined in this study to establish a research framework that affects cyclists in using bicycle GPS navigation systems. Between December 2012 and February 2013, this study focuses on cyclists in the 67th through 70th groups participating in the cycling event held by the Association of Cycling around Taiwan for purposive sampling. 244 questionnaires were released, and 239 valid questionnaires were received (with valid questionnaire rate of 97.95%).

SPSS and AMOS statistical software are used as statistical analysis tools to evaluate the fitness of the model and explore correlations among variables. The research results are as follows: 1. No differences between the model expectation covariance matrix and sample covariance sample were found; 2. Computer self-efficacy does not have a significant positive effect on perceived usefulness; 3. Computer self-efficacy has a significant positive effect on perceived ease of use; 4. Perceived ease of use has a significant positive effect on perceived usefulness; 5. Perceived usefulness has a significant positive effect on usage attitudes; 6. Perceived ease of use has a significant positive effect on usage attitudes; 7. Usage attitudes have a significant positive effect on behavioral intentions; and 8. Perceived usefulness has a significant positive effect on behavioral intentions.

Based on the study results, bicycle GPS navigation system businesses should manufacture products that are easy to understand, and should help cyclists feel that the system is useful for planning rides; this can elevate the preference and behavioral intentions for the products.
