This book evaluates how Public-Private Partnerships (PPPs) have evolved from simple financing tools into complex ecosystems that play a central role in addressing global infrastructure gaps. Wei Xiong traces this transformation over three decades, moving beyond Western-centric perspectives to examine the distinct experiences of the Global South and China. Xiong charts the evolution of PPPs from financing-driven arrangements (PPP 1.0), through efficiency-focused models (PPP 2.0), to sustainability-oriented partnerships (PPP 3.0). He integrates economic efficiency, political incentives and public values to provide a coherent framework for understanding why some partnerships succeed and others fail. Drawing on comparative evidence and real-world cases, the book demonstrates how governments and private actors can better create, manage and adapt PPPs over time.

It also argues that the future of PPPs lies in broad, multi-actor collaborations designed to address the Sustainable Development Goals. The Origins and Evolution of Public-Private Partnerships is a vital resource for scholars and students of political economics, public administration and public policy. Policymakers and sustainable development professionals will also benefit from its comparative cases and practical lessons.
