Although the 1988 Local Finance Act was amended several times (in 2005, 2009 and 2011) to enhance fiscal decentralisation, subnational governments in Korea still depend heavily on central government transfers. In 2013, the share of central government in total subnational government revenue in Korea remained well above the OECD average (61.6% vs. 37.3%) (Figure 1.22 and Box 1.8). According to the Act on the Management of Grants, the national government provides grants to cover part or all of the costs of traffic-related investments in cities and provinces.
