隨著科技的發展，世界各大城市也陸續提倡智慧城市的發展。共享機車的世界採用率逐年增長，台灣於2016年開始WeMo進入台灣市場提供共享機車服務。經過六年，目前台灣已經有三大主要的共享機車服務供應商，分別為WeMo、Goshare以及iRent。台灣做為全世界機車密度最高的國家，過去關於共享機車的相關文獻卻非常匱乏。過去的文獻著重在探究使用者對於共享機車的使用態度、認知行為以及主觀規範如何直接影響使用者的使用意圖，對於外在環境影響使用者的意圖極少被探討，而這關係到政府如何協助發展共享機車服務以利智慧城市的發展。因此，綜觀上述的現況分析，本研究嘗試從計畫行為理論出發，並且透過政府補助以及生態系統的完整性兩個中介變數的影響下，探討何種外部影響對於使用者使用共享機車服務的意圖的效果較為強烈。
本研究透過線上問卷方式進行樣本蒐集，使用一般線性迴歸分析進行研究假說驗證。從實證結果發現政府補助以及生態系統完整性都能增強共享機車的使用意圖。進一步將兩者進行比較，政府補助影響的效果較生態系統完整性更為強烈。本研究的發現不僅提供台灣政府提升共享機車使用率以促使智慧城市的發展的可實行的操作建議，同時也補足在行銷研究領域的學術文獻上，外部環境如何影響使用者的行為動機的論點。

關鍵字詞：共享機車、政府補助、生態系統完整性、計畫行為理論

With the development of technology, major cities in the world are advocating the development of smart cities. The world adoption rate of ride-sharing scooter is increasing year by year. Taiwan, as the country with the highest density of motorcycles in the world, has few literatures on ride-sharing scooter in the past. Previous literature focused on exploring how users’ attitudes, perceived behavioral control, and subjective norms directly affect users’ intentions to use ride-sharing scooter. The influence of the external environment on users’ intentions has rarely been explored, which is related to how the government assists the development of ride-sharing scooter services for the development of smart cities. Therefore, this study attempts to start from the theory of planned behavior, and under the influence of two intermediary variables, government subsidies and the integrity of the ecosystem, to explore what kind of external influences affect users' intentions to use shared scooter services. effect is stronger.

In this study, data were collected through online questionnaires, and general linear regression analysis was used to test the research hypothesis. From the empirical results, it is found that government subsidies and ecosystem integrity can enhance the use intention of shared locomotives. Further comparing the two, the effect of government subsidies is stronger than that of ecosystem integrity. The findings of this study not only provide feasible operational suggestions for the Taiwan government to increase the utilization rate of ride-sharing scooter to promote the development of smart cities, but also complement the academic literature in the field of marketing research on how the external environment affects users' behavioral motivations.
