尽管私营部门参与公共服务提供并非新事，但当前政界对公私伙伴关系（PPP）作为撬动私人资金的重要途径表现出浓厚兴趣。捐助国政府和各金融机构，例如世界银行集团（WBG）及其他多边开发银行（MDB），已设立多项倡议，推动各国监管框架作出改变以容纳 PPP，并为 PPP 项目提供咨询与资金。
Although the involvement of the private sector in public service provision is not new, there is currently keen political interest in PPPs as an important way to leverage private finance. Donor governments and financial institutions, such as the World Bank Group (WBG) and other multilateral development banks (MDBs), have set up multiple initiatives to promote changes in national regulatory frameworks to allow for PPPs, as well as to provide advice and finance for PPP projects.
