Table 16, which presents the distribution of PPI projects by their PPI-types during the 1991-
2018 period shows that some variations in PPI-type exist depending on the characteristics of
individual sectors. Table 16 shows that greenfield projects have been the most frequently used
PPI type in all sectors but transport, which mostly adopted brownfield. On the other hand, both
energy and ICT sectors applied divestitures more frequently than the other three sectors in both
absolute and percentage terms. In addition, water and sewerage sector used management and
lease contracts more than any other sector did. Among various PPI types, brownfield projects
have been the most common form of PPI investment in the transport sector with a share of
60.3% whereas 32.1% of the transport PPI projects has been implemented through greenfield
schemes. Divestitures andmanagement and lease contracts had relatively lower shares, i.e. 4.0%
and 3.6%, respectively.
