Conclusions
For reasons discussed in preceding chapters, public–private partnerships (PPPs) are unlikely to have major positive impacts on achievement of the Sustainable Development Goals (SDGs) or on the provision of transformational regional infrastructure, as envisioned by the G20. PPPs will continue to play modest but still important roles in the cost-effective provision of infrastructure service in many developing countries, as long as they are well structured, appropriately supported, and carefully monitored and evaluated. But PPPs made sustainable with large measures of concessional finance will do a disservice in the developing world if they distract from the fact that the fundamental causes of poor infrastructure service delivery in developing countries have very little to do with the availability of private investment. Those causes involve things like government policies, institutions, technical capacity, as well as the political economy realities of these countries and their relationships with development partners
