中文摘要：

公共服务合同外包会遭遇各种风险。从委托代理理论的分析视角看，集中表现为道德风险、寻租风险和公平风险。究其原因，在于我国公共服务合同外包的过程中政府规制不足，市场化逐步演化为一个用私人垄断代替政府垄断的过程。由此要保障公众的基本权益，必须强化政府在公共服务供给中的责任，破除各类垄断，维系适度竞争。

英文摘要：

Outsourcing of public service contracts will encounter a variety of risks. From the perspective of principal-agent theory, the risks are concentrated on such types as moral hazard, rent-seeking risk and equity risk. It is because of the lack of government regulation during the process of public service contract outsourcing. As a re- sult, marketization gradually evolves into a private monopoly instead of the government monopoly. Thereby to pro- tect the basic rights of the public, we must strengthen the government＇s responsibility in the supply of public serv-ices, and get rid of all kinds of monopolies, to maintain moderate competition.
