Recently, China's railway fixed asset investment remained stable. Statistics show that from 2014 to 2017, the investment in railway fixed assets in the country totaled RMB 808.8 billion yuan, RMB 823.8 billion, RMB 801.5 billion and RMB 801.0 billion respectively. However, according to Anbound, despite the investment return, investment in the past over the past exceeded RMB 800 billion; the slowing economic growth and then establishment of the railway network has caused high-strength railway fixed asset investment levels difficult to be sustained.
