In this paper, we conduct an empirical analysis of the online appliance market based on the price dispersion model generated by Dong Lihong. Our sample consists of 6442 price observations on 877 household electrical appliances from www.smart.com.cn. Our results show that price dispersion in the online appliance market is high, pervasive, and persistent, and cannot be viewed as a transitory phenomenon in an immature online market. Further, we investigate the causes of price dispersion in the online market by examining heterogeneity of online retailers, consumers' searching costs, differences in product attributes, limited transparency of the online market and the reliability of online transactions.
