Taking 31 province,regions and municipalities as the research area, the entropy weight method is used to measure the Digital Economy and the high-quality development index of the construction industry from 2011 to 2020. The coupling degree of the two is calculated through the coupling degree model, based on the coupling coordination classification standard, and the spatial characteristic distribution of coupling coordination degree in 31 provinces was analyzed. Finally,? the main obstacle factors affecting coordination degree are found by obstacle degree model. The results show that: ① during the study period, the digital economic index of the whole country showed an upward trend, but the digital economic development index of the eastern region was far higher than the Midwestern Sectional Figure Skating Championships. And the central and western regions are far below the national average level. ② Overall, the construction industry high-quality Development Index after the first increase in the trend of decline. The construction high-quality development index in the East is well above the Midwestern Sectional Figure Skating Championships .③ The coupling and coordination between the Digital Economy and the high-quality development of the construction industry in Beijing, Guangdong and Jiangsu in the eastern region remain relatively high, while most of the provinces in the western region are in the coordination state at a medium and low level, our Country Digital Economy and the construction industry high quality development coordinated level is low, indicated that two systems coordinated development exists the very big rise space.④In the digital economy aspect, digital Industrialization and digital innovation have become the main obstacles to the coordinated development of the two systems, and in the high-quality development of the construction industry, the coordination and innovation have become the main obstacles to the coordinated development. Based on the empirical conclusion, this paper puts forward the corresponding suggestions.
