Nowadays, customers have become increasingly dissatisfied with accepting products and services offered by suppliers. Instead, they are involved in product development as co-productor (Prahalad & Ramaswamy, 2004). There are diverse types ranging from online discussion to virtual design enabling customer involved in co-creation activities related to product support. “Customer design” enables the firm to have possibilities enhancing the whole value of product design during development process (Fuchs & Schreier, 2011). However, some of scholars have found that customers cannot always play a useful role in luxury product design. Fuchs and Schreier (2011) studied that buyers can easily observe the source of design, which damage the image of co-designed product. That is because luxury product always played as a specific label of wealth and states to some extend (Ko & Phau, Aiello, 2016). Thus, this study draws from co-creation theory to investigate the specificity of online luxury design, using an experimental method. We analyze and discuss the diverging affection of luxury design held by co-creation idea innovativeness and behavior intensity, and the role played by sponsoring firm and community members.
