竞争市场 可竞争市场
In economics,a contestable market is a market served by only one firm,but with mandated "competitive" pricing,so as to second the monopoly held by said firm on said market.Its fundamental feature is low barriers to entry and exit; a perfectly contestable market would have no barriers to entry or exit.Contestable markets are characteristed by 'hit and run' entry.If a firm in a market with no entry or exit barriers raises its prices above marginal cost and begins to earn abnormal profits,potential rivals will enter the market to take advantage of these profits.When the incumbent firm(s) respond by returning prices to levels consistent with normal profits the new firms will exit.In this manner even a single-firm market can show highly competitive behaviour.
