Abstract The "city-region" system theory considers that, with the rising regional economy and urbanization level, city has already become the core spatial support of modern regional economic element and indsuatrial centralization and decentralization, but the development and change of city is restricted by urban economic function, and the adjustment of industrial structure will have a great influence on city land structure and spatial form. At the same time, from the angle of supply factor of urban industrial structure change, the upgrading and changing of industrial structure depends on urbanization spatial support such as expanding urban spatial form,developing new urban areas and so on, which makes upgrading of industrial structure and evolvment of urban spatial form produce interaction mechanism.
The upgrading of industrial structure is the major force which promots the evolvement of urban structural form, and the adjustment course of modern urban space is the dynamic change course of optimization and upgrading of industrial structure continuously. The adjustment of the structural form of urban space has important support, pulling the carrier effect on the optimization and upgrading of industrial structure. So it will be the city and region's inevitable trend coupling between upgrading of industrial structure and optimization of urban spatial structure in future development.
Changchun has been constructed and developed for 200 years, and the interaction of urban industrial structure and spatial form structure has been changing from weak to strong. With the application of new technology and power pluralism of urban development, it will be enhanced constantly for the interaction in tensity between industrial structure change and urbanization of Changchun in the future.
