Garrett, Korea University, Republic of Korea4) ABSTRACT Product and service are not the only way to win competitors in business. The company should find better competitive advantages. How to seize present customers and explore the potential customers become more important (Rust et al, 2004). Sustainable development has been studied for many years. Corporate sustainability management has been defined as profit-driven corporate primary with secondary attention to environmental and social issues (Salzmann, Steger, & lonescu-Somers, 2005). From a more-focused business perspective, corporate sustainability can be defined as a business approach that creates long-term shareholder value by embracing opportunities and managing risks derived from economic, environmental, and social developments.

Because sustainable marketing can increase firms’ profit and improve the environment such as nature environment and society. Customer equity, the sum of customer lifetime value, comes from value creation based on profits, costs, cash flow, customers, and customer relationships. Customer equity emerges when companies maintain customer relationships for a long time; that is, lifetime value equals current value (Blattberg & Deighton, 1996). The concept focuses on maximizing benefits in direct marketing and advancing marketing technology. Customer equity has been defined as value of future profits that might be acquired from customers, excluding corporate costs (Berger & Nasr, 1998), as profits created when companies allocate resources appropriately to acquire and retain customers (Blattberg & Deighton, 1996), and as the sum of all customers’ discounted lifetime value (Lemon et al., 2001). The discounted lifetime value comprehensively expresses such concepts as acquisition and retention of customers, profits, and costs. Earlier researchers mentioned the discounted lifetime value from financial perspectives, and subsequent studies adopted the term. Rust et al. (2004) defined customer equity as the total of the discounted lifetime values over all current and potential customers.

It is not only focus on product and service (value equity), but also concern such as brand equity which is an intangible asset. Customer equity can estimate customer lifetime value for the company (Rust et al, 2004). The firm can make proper marketing strategy with customer equity. Customer equity can both satisfy consumers and make a profit for the company (Lemon et al., 2001). This study wants to study the relationship between sustainable marketing performance and customer equity.
