摘要 近幾年來，智慧型手機靠著其方便多元的功能，已經成為大部份消費者生活中不可或缺的一部分。App Store的出現使行動應用程式開發的市場較傳統應用程式開發市場容易進入。透過App Store，開發者可以直接將軟體賣給位於世界各地的消費者。本研究想了解在一個發展如此迅速的市場中是否存在著先進者優勢，以及該如何維持其優勢。

本研究屬於一探索式研究，本研究探討了過去的先進者優勢相關文獻，以了解傳統產業中的先進者優勢。先進者優勢的來源主要有：技術領導、資源佔有、轉換成本、網路外部性與定價優勢。為了瞭解在行動應用程式市場中是否存在先進者優勢以及如何維持優勢，本研究蒐集並分析了過去幾年來的行動應用程式排行榜的相關資訊。發現在行動應用程式開發市場中存在著上述之先進者優勢，本研究也發現這些優勢可以透過持續更新、與社群平台整合等策略來維持。
The applications (apps) on Smartphones exhibit many kinds of innovation. With the powerful features of Smartphones, people can easily access the Internet, social networking, e-mail, and instant messaging. The emergence of app stores has removed the barriers of big investments in hardware and software for software development and has made software development simple and easy, with a few people or even a single person doing the work and quickly reaching users directly around the world. These unique features of app innovation create a need to explore whether first-mover advantages exist in app development and whether these first-mover advantages, if they exist, can be sustained.
This exploratory study reviewed the literature about first-mover advantages in products, services, and e-commerce innovation. First-mover advantages often arise from sources such as technological leadership, resource pre-empting, switching costs, network externalities, and pricing advantages. With the objective of understanding whether first-mover advantages exist in app innovation and how first movers can sustain these advantages, this study have collected data about top-ranked apps of different kinds and analyzed their competitiveness, and this study presented our findings about the situation of first movers in the app market. This study found that apps enjoy advantages such as those mentioned above. This study also discovered that apps may sustain their competitive advantages through strategies such as updating regularly to improve services by integrating with social networks and establishing brand recognition through Facebook fan pages, Twitter, and blogs.
