Abstract
Many commons play important roles in the regional life, although they often cause “social dilemmas” as well as “unintended consequences”. At first, this paper tends to arrange the forms of social dilemmas and conflicts as to the common forests (lri-ai). The common forests has been broken up in the process of modernization. This process of change including the chain of unintended consequences and conflicts will be formulated by a time dependent Markov chain model. We examine in the model under what condeitions forests from being broken up.
