A name brand community functions as an important way to advertise products of an enterprise and win their consumers， but most of the members are not active. To solve this problem， and based on the view of adjusting match， the author explores two ways of acquiring knowledge (the perspective of knowledge acquisition) and how to match the two ways of adjusting focuses (promoting type and defensive type) in order to encourage consumers to participate in the action. We come to learn through 167 consumer interviews and objective data and most of hypotheses have been verified. The results indicate that the adjusting match (promoting type and dynamic way of acquiring knowledge， defensive and static way to acquire knowledge )promotes consumers to have the intention to join in while the unmatched adjustment (defensive and static way to acquire knowledge) discourages consumers to have such an intention to participate in the activity.
