Research on the Evaluation of Construction Regional Development Level Based on the Whole Industry Chain

Abstract From the perspective of the whole industry chain, this article divides the construction industry from the construction process, construction products, and participants into the whole process, all-round, and full-staff principles, and divides the construction industry of each province into upstream industries and midstream industries based on all links of the entire industry chain. This paper constructs the evaluation index system of three dimensions of downstream industry. Based on valid statistical data, the development level of the construction industry in 28 provinces in my country in 2019 was analyzed based on combination weighting and principal component analysis, and the development level of the construction industry in each region was ranked. The results show that there are obvious regional differences in the development of construction regions. The development level of the construction industry in the eastern and coastal provinces and cities is significantly better than that in the western and central provinces and cities, which is consistent with the status and verifies the validity of the model.
