中文摘要：

垄断性产业的管制机构不同于一般政府行政机关，具有较高的管制效率；管制机构的相对独立性是维持其权威性，保持管制执法公正性的基本前提；应以现代管制理念为基本原则设立高效率的管制机构；管制机构的基本权力是履行其管制职能的法律基础，主要体现在准立法权、行政权和准司法权；只有当管制机构的管制收益大于成本时，管制机构才是有效的，两者的对比关系是评价管制机构有效性的重要指标。

Unlike ordinary administration organ in government, the supervision institutions of monopoly industry have higher supervising efficiency. The relative independence of these institutions is the fundamental premise for maintaining their authority and keeping the equality of supervision and law enforcement. Effective supervision institution should be established with modern supervision conception as its fundamental principle. Basic rights of supervision institution are the law base for fulfilling the supervising function, which mainly embodies in quasi-legislative power, administrative power and quasi-judicial power. Only when the profit of supervision institution is higher than its cost, the institution is effective.
