智慧型手機和平板電腦的蓬勃發展，帶動了行動應用程式產業的興起，亦使 Android 應用程式商店如雨後春筍般湧現，並以成為 Android 應用程式之消費與散佈的入口商店為目標。本研究採用質性研究方式探討 Android 應用程式商店供應商（Google、智慧型手機與平板電腦製造商、電信業者（MNO）、獨立應用程式商店和應用程式開發者）為何以及如何建立之間的競合關係。雖然供應商為了讓 Android 作業系統、設備及應用程式的普及化而相互合作，卻又彼此競爭因普及化所帶來的利益。期間的競合關係會隨時間而變化，因此帶動了 Android 應用程式的發展。本研究提出四個有關 Android 應用程式供應商競合關係之研究方向，讓未來研究人員能以此更進一步了解以及探討 Android 行動應用程式產業間的競合關係。

The global proliferation of smartphones and tablets is creating a huge industry of mobile applications, which, in turn, gives rise to a number of Android application stores aiming to become the main entry point for the consumption and distribution of Android applications. By using qualitative research, this study explores and analyzes why and how the providers of Android application stores – Google, mobile device manufacturers, mobile network operators (MNOs), independent web portals, and application developers – engage in co-opetitive relationships with one another. Even though these providers are cooperating with one another to proliferate adoption of Android OS, Android devices, and Android applications, they are also competing against one another to capitalize on and earn revenue from the development and distribution of Android applications. Evolving over time and dynamic in nature, these co-opetitive relationships are instrumental in the distribution process of Android applications. This study provides timely and relevant insights into and four propositions regarding co-opetition in the mobile application store industry, enabling researchers to better understand co-opetitive relationships among the providers of Android application stores and to have starting points for future empirical research.
