Impact Evaluation of Subnational Infrastructure Investment in Indonesia (road and market investments)

Indonesia is undergoing a major and rapid structural transformation, but with a population of more than 250 million and the poverty level is 11 percent in 2014, Indonesia faced a large local infrastructure deficit. Levels of access to and the quality of basic services – such as healthcare, education, clean water supply, sanitation, and transportation – remain low and in many cases worsening. Subnational governments are responsible for 60 percent of consolidated public infrastructure spending, but this is barely sufficient to keep up with the depreciation of local public assets, even larger demand for new infrastructure. In addition to inadequate finance, subnational governments have also lacked the technical, institutional, or financial capacity to carry out strategic infrastructure investments and keep pace with rapidly expanding demand for local service.  

 

The Ministry of Finance (MoF), in partnership with the World Bank, has completed the process of setting up a Regional Infrastructure Development Fund (RIDF) that will institutionalize the business of lending for municipal infrastructure and implemented by PT. Sarana Multi Infrastruktur (PT. SMI). The World Bank is working in close coordination with the MoF and PT. SMI to help implementation of the RIDF. One key area of institutional support is to strengthen the capacity of PT. SMI in systematically evaluating the outcomes or impacts, effectiveness, and value for money of municipal lending to SNGs. As mandated by the MOF, PT. SMI is expected to grow its portfolio on municipal lending in the next few years, and conducting impact evaluation, therefore, will help PT. SMI make informed decision when providing loans to SNGs to achieve better development outcomes.
