本书旨在通过对欧盟和中国PPP法律法规的比较，识别、澄清和讨论欧盟和中国PPP法律法规可能带来的法律挑战，并且试图从欧盟的经验中为中国提供一些有益的借鉴。在欧盟和中国，PPP都受到公共采购法律框架的规制。从理论上讲，公共采购立法对PPP的规制存在两大挑战：一是如何将具有复杂性的PPP纳入传统的公共采购法律规制。二是如何平衡法律规制的灵活性和刚性。如果法律规制过于灵活，公共利益很可能会因为不可预料的机会主义行为而受到损害；如果监管过于僵化，则会失去最佳选择的机会。依照项目运行的时间线，本研究包括以下几个部分：公共采购法规对PPP的适用问题分析；PPP项目的采购程序、PPP项目实施阶段合同的修改和分包；以及公共采购的救济措施。通过比较研究，结果表明欧盟的立法可以为PPP提供更好的保护。借鉴欧盟相关法律法规，中国应更新公共采购、特许经营和PPP的概念，使PPP完全纳入公共采购法律框架的范畴；同时应重新调整现行公共采购法律框架，并将救济立法纳入该框架；中国还需要重新调整合同授予程序、合同修订和分包程序，确保这些程序在严格和灵活之间达到平衡。

从理论上讲，公共采购立法对PPP的规制存在两大挑战：一是如何将具有复杂性的PPP纳入传统的公共采购法律规制。二是如何平衡法律规制的灵活性和刚性。如果法律规制过于灵活，公共利益很可能会因为不可预料的机会主义行为而受到损害。

依照项目运行的时间线，本研究包括以下几个部分：公共采购法规对PPP的适用问题分析；PPP项目的采购程序、PPP项目实施阶段合同的修改和分包；以及公共采购的救济措施。通过比较研究，结果表明欧盟的立法可以为PPP提供更好的保护。
