Economic corridors are an increasingly important and relatively new model of regional development.Among them，the Greater Mekong Sub-region（GMS）Corridor has grown mature in terms of size and mechanism，and has a strong international exemplary significance.However，it should also be seen that the urban system of the GMS corridor still has many shortcomings，and the future development still faces great challenges.Its future upgrading strategies include strengthening Intermodal transport corridors，focusing on the development of medium-sized cities，accelerating the development of green cities，encouraging the private sector to participate in the development of GMS corridors，upgrading the level of agricultural and logistics development in corridor areas，and vigorously developing tourism and urban facilities.
