3. Technology Innovation and Application

China leads the world in infrastructure construction. China's technologies for high-speed, alpine, plateau and heavy-haul railways have reached the world's advanced level, while high-speed railways have become a symbol of made-in-China and going-global products. Railway and highway construction technologies have overcome world-level geological challenges such as plateau permafrost, and expansive soil and desert. The construction of the Qinghai-Tibet Highway and Qinghai-Tibet Railway has been completed and they have been opened to traffic. A number of world-class large bridges and tunnels have been built with globally advanced construction technologies. China's key construction technologies for offshore deepwater ports, improved technologies for large estuary waterways and long waterways, and construction technologies for large-scale airports are leading the world. The Hong Kong-Zhuhai-Macao Bridge, Yangshan Port Container Terminal, Yangtze Estuary Deepwater Channel Improvement Project, and other major construction projects have been carried out.

Equipment manufacturing has made rapid progress. High-performance railway equipment technologies with proprietary intellectual property rights, represented by high-speed railways and high-power locomotives, have reached the advanced world level, with some of them leading the world. New-energy road transport equipment has realized preliminary industrialization. Feeder liners, general aviation aircraft and helicopters independently developed by China have been put into use, and the C919 airliner has rolled off the assembly line, making China one of the few countries capable of developing large airliners independently. China's manufacturing technologies for large, specialized equipment for terminal loading and unloading, special marine engineering machinery vessels and complete sets of container transport equipment are world-leaders, while its 300-m saturation diving technology has achieved a breakthrough. Sorting technologies in postal services, including optical character recognition (OCR), video complement and address check via bar code have reached the world' s top level.
