Abstract: Industry cluster is promoting the expansion of urban construction and the rational flow of population and other resources between cities, while city cluster is providing industrial cluster with high-quality urban construction facilities, production factors and various scientific, technological and system innovations. When analyzing the spatial-temporal evolution and interaction between urban agglomeration and industrial agglomeration in the central region, this paper finds that there exists a certain difference in the time and space between them, there is no complete synchronous development. At the same time, the panel data regression model of the interaction between industrial agglomeration, urban agglomeration and economic growth is built. The results prove that industrial agglomeration has a great influence on the regional economic growth and that urban agglomeration has less effect on regional economic growth, while the interaction between industrial agglomeration and urban agglomeration has no significant promoting effect on regional economic growth.

Key words: industrial cluster; city agglomeration; economic growth
