According to the China Urban Rail Transit Development Report released by the transportation department of China's National Development and Reform Committee (NDRC) on December 14, investment in 2012 in construction of urban rail transit projects or metro projects in 35 cities in China amounted to RMB 260 billion ($41.6 billion).
In 2013, the total investment in question will see 15 percent growth to RMB 280-290 billion ($44-46 billion) due to the expected start of construction work on new metro projects which have already been officially approved.
Furthermore, sales of metro trains for the domestic market are expected to reach RMB 28 billion ($4.5 billion) in 2017, up from RMB 10.9 billion ($1.7 billion) in 2011.
