電動汽車共享系統的出現將為人們提供一種新的運具選擇，透過汽車共享來替代私有車輛的方式，可以改善交通問題與環境品質。本研究旨在了解影響人們使用電動汽車共享系統採用意圖的因素，以計畫行為理論（Theory of Planned Behavior, TPB）與科技接受模式（Technology Acceptance Model, TAM）為基礎研究模型，並結合永續性和知覺利益（經濟與地點）。不同於以往的研究課題皆關注在已有使用者的現有系統，本研究則是以僅有潛在使用者的剛興起系統者為研究對象，即是電動汽車共享系統。採用便利抽樣來收集問卷，刪除無效問卷後共計有333份有效問卷。研究結果顯示，知覺易用性、永續性與知覺有用性對於態度有顯著的正向影響效果，且近一步影響採用電動汽車共享系統的意圖；而知覺行為控制、態度與地點利益則是對於採用意圖有直接顯著的正向影響。這表示態度為重要的中介因素，研究中亦發現經濟利益與主觀規範對於採用電動汽車共享系統的意圖呈現不顯著的關係。

E-car sharing will provide a new transport mode for people to commute in the city. Traffic problems and environmental quality can be improved by using sharing cars to replace owning it. The purpose of this study is to know the factors affecting people’s intention to adopt e-car sharing system. This study applies Theory of Planned Behavior (TPB) and Technology Acceptance Model (TAM) as the basic research model, and combines it with sustainability and perceived benefits (locational and economic). Different from the previous studies concerning the existing system which already have users, this study focuses on the just emerging system which only have potential users, namely e-car sharing system. Convenience sampling is used to collect questionnaires. There are 333 valid questionnaires after deleting the incomplete ones and the scribble response. Results reveal that perceived ease of use, sustainability, and perceived usefulness have significantly positive effect on attitude, and further on intention to adopt e-car sharing system. In addition, perceived behavioral control, attitude, and locational benefit have the significantly positive effect on intention to adopt directly. It shows that attitude plays an important mediator role. This study also finds that economic benefit and subjective norm are insignificantly related to intention to adopt e-car sharing system.
