以高中職校在學學生為研究對象,採多階段集群抽樣藉由探討不同背景變項的高中職學生使用行動上網的習慣,以及對行動定位即時服務的接受度;另不同行動上網習慣與偏好的高中職學生,其知覺重要他人的人際功能的差異性,及他們對於群組人際功能的認同度是否影響其接受行動定位即時服務,希望提供相關人士或行動業者,能夠提升即時行動服務的內容,提供更貼近青少年學生的行動即時服務。研究顯示:一、行動上網現況部分:1.高中職學生最常使用的手機App軟體第一名為「Line」,第二名為「Facebook」。2.高中職學生最能接受的數位行銷策略為「口碑行銷」與「在地化服務訊息」。3.「經常使用的手機App類別」性別、年級略有差異。4.高中職學生對「意見領袖」的認同感普遍來自於「使用經驗」。二、高中職學生使用行動上網介面對於「同儕群組人際功能認同度」的幫助要比「親子群組人際功能認同度」來得高,其中又以提高「友誼陪伴」及「資訊流通」功能為最。三、高中職學生對群組人際功能認同度與其接受行動定位即時服務具顯著相關性。四、高中職學生對同儕群組人際功能認同度比對親子群組人際功能的認同度,對接受行動定位即時服務更具有顯著預測力。 The study takes current students in high and secondary vocational schools as research objects and utilizes multi stage cluster sampling, to explore the internet surfing habit with mobile devices of students of different background variables, as well as their acceptance degree to the real-time location service in mobile devices; it also studies the differences of students with different surfing habits and preferences in their perception of interpersonal functions and whether their identity degree of interpersonal functions may affect them on accepting real-time locations services. It is expected to provide references for relevant personnel and mobile service providers to improve the real-time service contents and provide students with real-time services close to the students’ demands. I. Current situation of internet surfing with mobile devices1. The top 1 of Apps most frequently used by students of high and secondary vocational schools is Line, followed by Facebook.2. The most acceptable digital marketing strategies for them are word-of-mouth marketing and location-based service information.3. Frequently-used App categories are slightly different in terms of students’ genders and grades.4. Students’ identity to opinion leaders is generally aroused by the users’ experiences. II. The influences of network surfaces on identity degree to interpersonal function among their peer groups are much higher than that on that of parent-child groups, in which the best performances are provided by friendship accompaniment and information flow.III. Students’ identity degree to group interpersonal function shows positive relations to their acceptance degree of real-time location services. IV. In contrast to students’ identity degree to interpersonal function of parent-child groups, their identity degree to that of peer groups has more significant predictive power than their acceptance degree of real-time location services in mobile devices.
