Expressway planning is performed by the Ministry of Transport of the People's Republic of China. Unlike the road networks in most nations, most Chinese expressways are not directly owned by the state, but rather are owned by for-profit corporations (which have varying amounts of public and private ownership) which borrow money from banks or securities markets based on revenue from projected tollways. Examples of these corporations include Huabei Expressway Co., Ltd., Northeast Expressway Co., Ltd., Hunan Changyong Expressway Co., Ltd., and Guangxi Wuzhou Transportation Co., Ltd. One reason for this is that Chinese provinces, which are responsible for road building, have extremely limited powers to tax and even fewer powers to borrow.
