This book explores and analyzes key areas of public-private partnership (PPP) involvement across a variety of development fields—the ‘triple interface’ of PPPs, intellectual property, and the UN Sustainable Development Goals (SDGs). The final chapter provides a partial synthesis, situating the various contributions within a global knowledge governance framework - that is, by evaluating whether and how PPPs encourage innovation, build innovation capacity, engage in technology transfer or sharing, or otherwise ensure wide dissemination and diffusion of innovation results across borders to advance the progress of the SDGs. Based on the evidence presented in this book, this chapter summarizes findings according to four thematic sections: aligning with public policy objectives; coordinating with other knowledge governance efforts; managing the partnership boundaries; and enhancing sustainable development. After this summary, which is illustrated with references to specific chapters, the chapter concludes with suggestions for a future policy and research agenda.
