The conception and the dimensions of relationship value were defined, and the model that describes the influences of relationship value dimensions on customer loyalty was built.  Using the data of the consumers of Chinese Etailers, the scale and the theoretical model were tested. Results indicate that relationship value includes three relationship benefit dimensions and two relationship cost dimensions. These five dimensions influence the customer loyalty indirectly through relationship satisfaction and relationship commitment. Relationship benefits influence customer loyalty positively, and relationship costs influence customer loyalty negatively.
