Environmental Resources' Property Ownership and Firms Behavior in Duopoly Market

It's an effective method to avoid environmental resources market failure through defining property rights. The controversial issue is property ownership should be adopted between the free and the paid. Based on the Cournot model in duopoly market, the article discuss the relation between the ownership of property rights and firms behavior by calculating the environmental resources input and goods output under the condition of profit maximization. Through comparing with the market structure in three property ownership, non-delimitation, free-delimitation and paid-delimitation, we get the conclusion: we cannot reduce the consumption level of environmental resources only by the delimitation of property rights. And only with a certain price to allocate rights, it's possible to attain Pareto improvement in resources utilization. In addition, although the paid-delimitation ownership will lead to a decrease of total output, the firms still have a motivation to improve technical efficiency, because their own and total market output both have business with the utilization efficiency of environmental resources in this condition.
