Research on the River-Crossing Development Process and Dynamic Mechanism in Nanchang City

Dynamic Mechanism of River-Crossing Development of Nanchang The river-crossing development of a city Is to achieve the self-expansion of the city by crossing the barrier of the river, a reasonable planning layout from one-side centered to two sides development, and a comprehensive river-crossing development that contains ideas, policy measures, resource elements, supporting facilities, Industries and talents. [...]If Nanchang wants to cross the threshold of "Ganjiang River" to achieve rivercrossing development, it should not only have the macro-guidelines of relevant policies and urban planning, the population and economic support that continue to grow, but also have the support of leading industries and convenient and efficient river-crossing traffic system. Economic growth The river-crossing development of a city requires a lot of capital investment in infrastructure and urban function development. [...]the economic strength of a city must be able to support the needs of such a huge project, or it will be extremely easy to break down. The evolution of urban spatial structure resulting from the river-crossing development of cities is also largely the result of such industrial development. Since 1949, the industrial structure of Nanchang has undergone a process of development from "first, tertiary, secondary", "secondary, first, tertiary" to the current "secondary, tertiary, first". The river-crossing development of a city not only requires a number of crossriver channels, but also needs to realize the diversification of river-crossing patterns, which can form a total crossriver traffic system with various organic modes of transportation, such as bridges, tunnels and rail transit. Since 1936, Nanchang has successively built various cross-river tunnels such as Bayi Bridge, Ganjiang River Bridge, Nanchang Bridge, Shengmi Bridge, Hongdu-Hero Bridge, Chaoyang Bridge, Subway and Honggu Tunnel.
