Abstract: On the basis of constructing an evaluation index system for the coupling and coordination of the construction industry and the regional economy, taking various province in China as the research unit, the entropy method and the coupling coordination degree model were used to quantitatively measure the coupling and coordination degree between the construction industry and the regional economy in China, and combined with ArcGIS10.5 to analyze the coordinated and coordinated development level and time-space distribution law of the construction industry and regional economy in various provinces in China. The research showed that:from 2011 to 2017, the coupling and coordination of the construction industry and regional economy in China could be generally divided into three types, with significant differences between regions, and there were more provinces with lagging regional economic development. The comprehensive development level of the construction industry and the level of regional economic development were unbalanced among these provinces, and the regional polarization effect was obvious. In general, the spatial pattern of coastal provinces was higher than that of inland provinces; there was a certain degree of differences between the construction industry and regional economy. The differences were in the stage of development from "multi-polarity" to"planar", and the radiating effect was obvious. On the whole, the degree of coupling and coordination between the construction industry and the regional economy was at the intermediate level of coordination, the overall synergistic development effect tended to increase, and the spatial distribution had not changed significantly.
