Due to intense competition among firms leading to a proliferation of similar products, consumers increasingly tend to rely on corporate value—such as preferences and favorable attitudes toward specific firms based on their direct and indirect purchasing experiences—rather than on the differentiating physical attributes of products when making product choices. In response to this trend in the market environment, firms have turned their attention to corporate identity as a means of enhancing competitive corporate value. This study, as part of foundational research activities for developing strategies to enhance a firm's competitive value, aims to establish the concept of corporate identity—which has remained at a speculative level—and, on that basis, to identify the components of corporate identity and their relative influence, thereby providing a research framework for evaluating corporate value through corporate identity. According to the empirical analysis, despite some differences, corporate identity is evaluated across five components—products, services, employees, distribution, and image—regardless of product type in terms of a firm's competitive value, and among these components, the image component was found to have the greatest influence on competitive corporate value. In particular, the influence of the image component was found to be greater for firms producing low-involvement product types. In light of these findings, this study has significance in providing criteria for evaluating a firm's competitive value through corporate identity, and it also offers the expected benefit of clearly identifying the sources of value formation, thereby suggesting the direction of activities and strategies for corporate managers and administrators to enhance their firm's competitiveness.
