Abstract：In contemporary China, the urbanites are "economic men" instead of modern citizens, their goals are to pursue the maximization of their instant interests.They are good at calculating costs and profits, then determine whether to participate and how to participate.It easily causes the community election into game of speculation.In the course of electing, in order to reach the aim of double over half, the local governments and community organizations can only dissolve this predicament through the incentive mechanism of the alternative (politics is mobilized or the material is encouraged), but the mechanism will be hard to carry on because of increase of the social cost. So it is the effective way to cultivate modern citizen society and strengthen resident ability of self-organizing.
