🚇Most Chinese cities struggle to make a profit from their subway systems due to high costs and limited construction space.
🔑Only major metropolises like Beijing and Shenzhen have the physical space and potential for profitability.
💰Many subway systems in China operate at a loss, even with government subsidies.
🏙️Shenzhen stands out as a profitable example due to its integration with local businesses and transit-oriented development.
🚂The National Development and Reform Commission (NDRC) controls subway construction and imposes strict requirements for expansion projects.
