App Usage Patterns in the Platform Economy: An Exploratory Study on Sustainable Digital Ecosystems and Device Possession

In the context of the platform economy, this study preliminarily examines how smart device possession affects the sustainability of app usage behavior. This research analyzes app usage as a core component of value creation within a sustainable digital ecosystem. As an exploratory pilot study serving as a proof of concept, we focus on how different ownership patterns influence digital consumption performance, categorizing users based on three dimensions: the number of devices owned, screen size (portability), and inter-device compatibility. Furthermore, the study elucidates how device relationships affect engagement across app categories, investigating whether devices function as primary, complementary, or independent tools. By analyzing these exploratory behaviors, the research offers insights into multi-device usage patterns for a more efficient digital experience while reducing resource redundancy. Ultimately, these findings provide practical guidance for fostering a more balanced and resource-efficient digital society.
