It is an important symbol for middle class to own the property.Many researchers in China believe that the property owners have a stronger consciousness of rights,who are prone to participate in collective action to protect their own interests.Based on the test from data of CGSS2006,this paper finds out that the above opinion does not fully comply with the reality.Even though participants benefit more from the collective actions,the probability of property owners’ participating in collective action is not obviously higher than that of non-property owners,and the probability for the property owners who have treated unfairly to participate in collective actions is also not obviously higher than that of non-property owners.This paper finally points out that rational mechanism should be established to guide all kinds of collective actions so as to achieve social stability and social harmony.
