Dongdaemun Fashion Town, a representative clothing wholesale and retail market in South Korea, is a traditional market that was formed in the 19th century in the late Chosun Dynasty. Since then, the market system has strengthened and, as of now, Dongdaemun Fashion Town can produce various products in batch production and is characterized by a quick market response (Jung, Choo, & Chung, 2007). Furthermore, all fashion-related functions are available, making Dongdaemun Fashion Town an industrial cluster where all related businesses and services are locally concentrated (Ko, Choo, Lee, Song, & Whang, 2013). These characteristics of Dongdaemun Fashion Town relieve market trade cost and build a unique production system. It is positioned as a central clothing wholesale and retail district with the function of a national wholesale market. This Dongdaemun Fashion Town system creates services that customers demand through cooperation, partnership, or outsourcing between various suppliers and various resources (Nam, Kim, Yim, Lee, & Jo, 2009). Thus, Dongdaemun Fashion Town is a system space composed of subordinate markets with unique taste functions; here, a systematic network between the suppliers is significant. It produces value co-creation through collaboration with suppliers. However, few previous studies have investigated co-value created through co-production or co-innovation from Dongdaemun Fashion Town. Also, the shift from product-centered thinking to the customer-centered thinking implies the need for an accompanying shift to the customer-based strategy. It also refers the necessity of strategy to improve customer equity (Rust, Lemon, & Zeithaml, 2004). Therefore, further study is needed on co-creation research to make cyclical growth of traditional market and customer equity. The structure of this study is as follows. First, the characteristics of the Dongdaemun Fashion Town’s co-production, co-innovation, and value co-creation are investigated and each of the subordinate aspects is investigated. Second, the influence of co-production, co-innovation, and value co-creation on customer equity driver is analyzed. Third, the moderating effects on the types of suppliers’ (wholesale/retail) influence relationship are analyzed. In total, 300 samples by wholesalers and retailers were collected for the final analysis. Data analysis was performed used SPSS 21.0 for exploratory factor analyses, reliability analysis, and descriptive statistics. Based on the results, AMOS 18.0 was used for confirmatory factor analysis and multiple group analysis. The results of this study provide an insight into the influence of Dongdaemun Fashion Town’s co-production, co-innovation, and value co-creation on customer equity by wholesalers and retailers. The study concludes with outlining future directions of research that can be used in the development of marketing strategies.
