Private Participation in Infrastructure Database (PPI)

The Private Participation in Infrastructure (PPI) Project Database has data on over 6,400 infrastructure projects in 137 low- and middle-income countries. The database is the leading source of PPI trends in the developing world, covering projects in the energy, transport, water and sewerage, ICT backbone, and Municipal Solid Waste (MSW) sectors (MSW data includes projects since 2008) Projects include management or lease contracts, concessions, greenfield projects, and divestitures.
The database records contractual arrangements for public infrastructure projects in low- and middle-income countries (as classified by the World Bank) that have reached financial closure, in which private parties assume operating risks.
Projects included in the database do not have to be entirely privately owned, financed or operated. Some have public participation as well.
With few exceptions, the investment amounts in the database represent the total investment commitments entered into by the project entity at the beginning of the project (at contract signature or financial closure), not the planned or executed annual investments.
For projects that involve investments, the database figures reflect total project investments encompassing the shares attributable to both the private and the public parties.

基础设施私人参与（Private Participation in Infrastructure，简称PPI）项目数据库收录了137个中低收入国家的逾6400个基础设施项目相关数据。本数据库是发展中地区PPI趋势的权威数据源，覆盖能源、交通、给排水、信息通信技术（Information and Communications Technology，简称ICT）骨干网以及城市固体废物（Municipal Solid Waste，简称MSW）等领域的项目（MSW相关数据包含2008年以来的项目）。收录的项目类型包括运营或租赁合约、特许经营项目、新建绿地项目以及资产剥离项目。
本数据库记录了按世界银行分类标准划定的中低收入国家已完成财务闭合的公共基础设施项目的合约安排，其中私人主体承担项目运营风险。
本数据库收录的项目无需完全由私人所有、融资或运营，部分项目亦有公共部门参与。
除极少数例外情况外，数据库中的投资金额代表项目主体在项目启动之初（合约签署或财务闭合阶段）达成的全部投资承诺额，而非计划或实际发生的年度投资额。
对于涉及投资的项目，数据库统计数据涵盖了私人与公共双方所持份额对应的全部项目总投资额。
