A convenient "traffic network" including the sea, land and air has been constructed in Hainan.

The island has the world's first roundabout high-speed railway, running through 12 cities and counties in the east and west. Total road length of the province is 20,860 km; the network density is 79.23 km/100 square km. Haikou Meilan International Airport and Sanya Phoenix International Airport have a combined throughput of 40 million person-times. Boao International Airport has been completed and put into operation. The system of "four directions, five ports", with Haikou port and Yangpu port as the two cores, has been improved on a daily basis.

A "province of all-optical networks" has basically been built. Urban areas, towns and administrative villages are covered with optical networks and 4G networks. Key public places are fully covered with Wi-Fi signals. The level of information infrastructure and the Internet speed of fixed broadband are among the highest in China.

The "power network" provides a strong guarantee. The province has an installed capacity of 7,879,300 kw, of which 4,363,400 kw is installed for clean energy. Large power stations such as the Changjiang Nuclear Power Plant have been built and are in use. The cross-sea power network enables connection between the Hainan Power Grid and the main network of China Southern Power Grid.

The "water network" is highly efficient. Hongling Reservoir and other major national water control projects have been established with a total capacity of over 11 billion cubic meters and the water saved in conservancy projects has reached 4.56 billion cubic meters.

The construction of a "gas network" has been accelerated. A west loop line of 637 km has been completed and put into operation. The urban gas pipe network covers over 50 percent of the urban population. The "Gasification in Hainan" program has been accelerated, and all counties will have access to pipeline gas by 2020.
