Abstract:An evaluation index system of 7 major factors and 23 observation indexes was developed on the competitiveness of construction industry. By combining the advantages of partial least squares(PLS) path model, technique for order preference by similarity to ideal solution(TOPSIS) model and cluster model, a comprehensive assessment was made of the competitiveness of Chinese construction industry, which was a portfolio innovation among the evaluation methods. Assessment results show that China’s construction industry is extremely unbalanced. The competition is subjected to the location, from the east coast region to the Midwest region, the competition inclining from strong to weak. Different developing strategies for improving the competitiveness of regional construction industry of different provinces in China were put forward with a view to provide theoretical guidance.
