The Impact of Construction Industry Structure Optimization on the Economy of Metropolitan Area - Taking Hefei and Nanjing Metropolitan Area as Examples

This research selected Hefei and Nanjing metropolitan area as the research object to analyze the optimization of construction industry structure in Hefei and Nanjing metropolitan area in 2018. Firstly, the construction industry structure rationalization analysis, heightened analysis, specialization analysis and similarity analysis were conducted for Hefei and Nanjing metropolitan areas, then the theory of construction industry structure optimization analysis was derived for Hefei and Nanjing metropolitan areas, and then ArcGIS technology was used to draw the spatial distribution map of construction industry structure in the two metropolitan areas to provide theoretical support for industrial structure optimization and high-quality construction of Hefei metropolitan area. Finally, the analysis concluded that in the process of synergistic development, the Hefei metropolitan area should focus on strengthening the synergistic development with Nanjing metropolitan area, so that the Yangtze River Delta region can achieve the optimization of economic structure preferably, advanced industrial base and modernization of industrial chain, and enhance the coordination of urban and rural regional development, thus making significant progress in the construction of modernized economic system.
