基于价格上限管制下上下游垄断企业的福利分析

Welfare Analysis Base on Price-Cap Regulationon Successive Monopolistic Upstream and Downstream Firms

在上下游垄断企业所带来的较低社会福利问题的基础上,分析了政府管制机构对下游垄断企业以及上游垄断企业分别实施价格上限管制情况下的利润、消费者剩余以及社会福利,并比较分析了上下游垄断企业在管制下的整个社会福利与未受管制时以及一体化时的社会福利,得出了一些新的结论.

Based on the low social welfare problem of successive monopolistic upstream and downstream firms, the authors analyzed the profits of these firms, consumer surplus and social welfare while these firms were under price-cap regulation respectively. Meanwhile, the authors compared the social welfare under regulated with the unregulated social welfare and incorporated social welfare. At last, the authors draw some conclusions.
