The Private Participation in Infrastructure (PPI) Database, with data spanning over almost 27 years, has established itself as a powerful tool and measure for gauging the level of private investment in infrastructure in EMDEs.
The Annual Report from the PPI Database for the year 2017 marks an encouraging increase of 37 percent in investment levels from 2016 levels. Yet, it remains the second lowest level of investment in the past 10 years. On closer examination, the increase is attributable to a few megaprojects in China and Indonesia as well as a recovery in South Asia, led mainly by Pakistan. Also notable is the fact that the average project size increased by 26 percent in 2017.
Interestingly, the upward turn in investment levels in 2017 appears to be positively correlated with the increase in government support to projects, signifying the important role played by government policy, regulation, governance and transparency in encouraging greater private participation in infrastructure.
