"Disentangling public and private contributions, 2017"

Infrastructure investment has been recognized as an accelerator of economic development, but little is known about the levels of total infrastructure investment and spending across the private and public sectors. The Private Participation in Infrastructure (PPI) database has 28 years’ worth of data on privatesector investment commitments (measured at financial close) to infrastructure projects in developing countries. However, there is little data on the corresponding public-sector investment commitments to infrastructure. With support from the Public-Private Infrastructure Advisory Facility (PPIAF), data was collected on infrastructure projects sponsored in 2017, either directly through public budgets or indirectly through state-owned entities (SOEs).

The data collection complements the PPI database and covers investment commitments in energy, transport, water and information and communications technology (ICT)-backbone projects in low and middle-income countries.

This report looks at data from state-owned enterprise and public projects and compares it to data on private participation in infrastructure. The result is a snapshot that shows the relative proportion of investment commitments made by the public, SOE, and private sectors to infrastructure projects at global, regional, and sectoral levels in 2017.
