A Study on Users’ Perceptions and Satisfaction with the Intelligent Real Estate Transaction System

This study empirically analyzes user perception and satisfaction with the Intelligent Real Estate Transaction System (IRTS) to identify the key factors for its stable settlement and diffusion. The IRTS was introduced in response to digital transformation and the growing demand for transparency and efficiency in the real estate market, aiming to simplify face-to-face transaction procedures, reduce costs, and save time. However, its adoption in practice has remained limited. Accordingly, this study explores not only the introduction of the system itself but also the processes through which users experience, perceive, and form satisfaction with IRTS. The research framework is grounded in the Theory of Planned Behavior (TPB), Innovation Diffusion Theory (IDT), and the Expectation Confirmation Model (ECM). These frameworks explain how attitudes, subjective norms, perceived behavioral control, relative advantages, complexity, and the alignment between expectations and actual experiences influence satisfaction and intention to reuse. Independent variables included technical factors (stability, security, accessibility, convenience), psychological factors (trust, expectations), institutional factors (legal reliability, administrative linkage, incentives, policy support and promotion), and cognitive factors (understanding, perceived usefulness, cost effectiveness), while satisfaction was set as the dependent variable. Data were collected through nationwide user surveys and expert assessments, and analyzed using factor analysis, ANOVA, regression analysis with SPSS, and the Analytic Hierarchy Process (AHP). The results reveal that low utilization of IRTS is due less to technical insufficiency than to institutional, psychological, and cognitive barriers such as uncertainty about legal reliability, low awareness, unintuitive interfaces, and accessibility issues among elderly or digitally vulnerable groups. In contrast, stability, convenience, and security were found to positively influence satisfaction. Expert evaluations further highlighted that securing legal credibility and strengthening education and promotion are the most critical determinants of successful diffusion. Policy implications suggest a two-track strategy: short-term provision of incentives to encourage adoption, and long-term reinforcement of legal and institutional foundations combined with systematic education and promotion. This study demonstrates that the diffusion of IRTS requires not only technological stability but also legal, institutional, and social acceptance, thereby providing practical insights for policy design and implementation in the digital transformation of real estate transactions.
