Existing studies related to store loyalty have focused on identifying individual variables that influence store loyalty, such as socioeconomic characteristics, geographic factors, and store image. As a result, research findings have been relatively fragmented and the explanatory power of research models has been very low, showing inadequate results in explaining store loyalty. Therefore, this study aimed to identify the important variables influencing store loyalty by introducing customer satisfaction and switching barriers, in addition to store image which has been argued as a determinant in prior store loyalty research, and conducting empirical analysis. Through this, the study sought to resolve the question of why customers exhibit high store loyalty toward specific retail stores, and in particular, to examine the influence of customer satisfaction and switching barriers on store loyalty, which had not been previously considered. The empirical analysis results yielded a conceptual model with enhanced explanatory power while maintaining parsimony regarding store loyalty, and suggested that the determinants of store loyalty are customer satisfaction and switching barriers rather than store image.
