The 20th CPC National Congress Report declared China will “build a modern infrastructure system”. Infrastructure investment has been an important component of Chinese economy，not only being a leading engine of economic growth，but also improving China’s TFP and promoting regional economic equality in the long run. In the future，China’s infrastructure investment will continue to focus on high-quality development，opening up tremendous investment opportunities，particularly around three areas（city-groups，rural revitalization，and fiscally subsidized regions）and five sectors（living standard-improving projects，transportation network，information technology，new energy system，social services）. At the same time，financing and business models of infrastructure projects will keep growing more regulation-compliant and more innovative，pushing investment projects to be more compatible with fiscal room and/or business profitability，resulting in a more sustainable infrastructure sector as a whole. This report also uses a cross-city high-speed rail project as an example to showcase how important infrastructure sector is to expanding effective aggregate investment，as well as immense value that a proper combination of public funding and private capital can generate.
