摘要
This paper provides evidence for the relationship between various forms of real options in infrastructure projects and the types and levels of government supports to the infrastructure investments. It analyzes the common real options and real options-based strategic investments and aligns them with the common types of public-private partnership （PPP） infrastructure projects. It then develops models to show that the real options incorporated into the different types of PPP infrastructure projects affect the level of direct government cash supports to the projects and hence the viabilities of such projects. The paper however shows that the relationship between the embedded real options and viabilities of infrastructure projects can be influenced by such factors as contract period and percentage of private sector contributions to the projects.
