The Strategy, Thinking and Method of New Urbanization
—The Idea of the Cluster-shaped Cities System of the Yangtze River Economic Belt
Fang Chuanglin Wang Zhenbo
Abstract: The system of the cities along the Yangtze River Economic Belt are pyramid-structured in terms of their size; the functions of the cities in the lower reaches are more complementary with each other than those in the middle and upper reaches, which are yet to form a complete system; the cities are unevenly distributed, causing high costs of city connectivity as well as great pressure on the resources and environment within the river basin. This paper suggested taking integrating the river basin as the main line, developing a necklace-like cities system where "the Yangtze River is the rope and the cities along it are the pearls"; focusing on integrating transportation, and developing a road system connecting all the cities and towns; being based on the integrated industrial distribution, and building a cities system where the industry and the city are integrated involving the full industrial chain; integrating the protection of the ecological environment, and developing an ecological cities system; combining the rivers and the sea, and developing a cities system of two-way opening up; and forming a cluster-shaped cities system.
Keywords: the Yangtze River Economic Belt, new-type urbanization, cluster-shaped cities system, world-class city groups, industrial integration
