贸发会议估计，要实现可持续发展目标，全球每年需要 3.3 万亿至 4.5 万亿美元的基础设施投资。《2030年议程》认识到仅靠各国政府的能力是无法调动这些资金的，并鼓励和促进利用公私伙伴关系来补充更为传统的基础设施筹资方法。
UNCTAD has estimated that achieving the Sustainable Development Goals would require investments in infrastructure of between $3.3 trillion and $4.5 trillion per year globally. The 203 0 Agenda recognizes that it is beyond the capacity of Governments alone to mobilize those funds and encourages and promotes the use of public - private partnerships to complement more traditional approaches to infrastructure financing.
