People believe that a perfectt competition market structure is the best way of allocating resources. However, a perfect competitiion market structure is just a hypothetical assusmption that cannot be achieved in real life. If only the price mechanism is adopted in allocating resources, market failure will result due to monopoly and asymmetric market information.

Was considered fully competitive market structure is the best way for the allocation of resources; but in the real economy, the perfectly competitive market structure is only a theoretical assumption that reality, it is impossible to entirely satisfied. As the monopoly of incomplete information in areas such as relying solely on the price mechanism to allocate resources efficiently can not be achieved, there has been market failure.

The people thought competes completely the market mechanism is the resources deployment best mode; But in the realistic economy, the perfect competitive market structure is only one kind of supposition theoretically, in the reality is impossible to satisfy completely. Because monopolizes, the information not completely and so on domains, depends upon the price mechanism to dispose the resources merely to be unable to realize the efficiency, presented the market malfunction.
