Many countries initially develop PPPs in the transport sector and later extend their use to other sectors, once the value for money benefits are proven and public sector expertise is established. This might hold true in the Finnish PPP cases. PricewaterhouseCoopers classifies countries as how they use PPPs. Finland belongs to the group: “Low Usage: Limited resource to the PPP model but growing interest”. There is potential for the PPP market to develop further. The Ministry of Transport has been the most active in developing PPP structures in Finland. (PricewaterhouseCoopers 2007: 42–43.)
