To explore the reasonable mechanisms of resources property rights and the complusory system, taking the radio spectrum as an example and in acorrding to the first order sealed auction principle, this paper establishes an incomplete information bidding model during the radio spectrum auction process to analyze the impacts on operators optimal of factors such as the number of operators bidding, bidding probability of success and so on, and the effects on operators expected profit function of the number of successful bidders, and draw the general expression of operators quote by solving model.Analysis showed that the application of auction mechanism in the radio spectrum resource allocation not only fully reflected the economic value of spectrum resources, but also conducive to the efficient allocation of spectrum resources, and was the ptimizing decisions as well under the premise that the profits of operators was maximized.
