As an intuitive embodiment of the city’s comprehensive strength, urban competitiveness, combined with the theory of regional gravity center, makes a comparative analysis of the urban economic migration of urban competitiveness in different years, which helps to analyze the spatial and temporal development differences of regional cities, thus providing a new perspective for the analysis and research of urban competitiveness. In the market economy, land price plays an important role in optimizing the allocation and intensive use of urban land resources. Therefore, it is of great practical significance for the government to reasonably allocate urban land resources and standardize the order of land market to master the spatiotemporal change law of urban land price and study the driving mechanism of land price change. This paper analyzes the urban economic migration with the help of GIS technology and carries out research at the same time, analyzes the spatio-temporal change law of the form, analyzes the urban form measurement, expansion intensity and expansion speed, and explores the driving forces and constraints affecting the urban spatial form. From this, we can obtain the spatio-temporal trajectory of GIS in urban economic migration and evolution, and the analysis and research of this trajectory can understand the direction of regional economic development and the balance of development.
