토픽 모델링 분석에 의한 전자상거래 주제어의 변화 과정 연구(2010~2025) -KCI 논문을 중심으로-

This study analyzes the thematic evolution of e-commerce research from 2010 to 2025 by applying LDA topic modeling and keyword analysis to 635 English abstracts of papers indexed in the Korean Citation Index(KCI). The study categorizes the research period into three phases: the expansion stage(2010~2014), the sophistication stage(2015~2019), and the transformation stage(2020~2025). The findings indicate that the period of 2010~2014 focused on addressing online uncertainties and verifying consumer trust–quality–satisfaction models, representing the expansion and theoretical application of e-commerce research. From 2015 to 2019, research incorporated social media and mobile diffusion, emphasizing information exchange and consumer experience, thereby extending quality and satisfaction models to digital interaction context. During 2020~2025, e-commerce research shifted toward platform-based ecosystems and data-driven analysis, highlighting how platform trust, recommendation systems, and technological factors restructure consumer behavior and market dynamics. These results empirically demonstrate the evolution of e-commerce research from consumer behavior models, through social and mobile experiences, to platform-oriented integrative studies. Practically, the study underscores the importance of sustained trust and quality management, optimization of consumer experience, and the transition toward platform and data-driven strategies. Theoretically, it provides insights into the developmental trajectory of e-commerce research and its academic linkage with platform theories and digital ecosystem studies.
