| Abstract: | This article is one of the results of scientific researches on topic "Strategy Support System for the Development of Education in Tianjin Architectural Industry and It's Application " funded by Tianjin Science and Technology Committee. An evaluation index system has been developed for evaluating the technical progress in architectural industry in Tianjin using the correlation analysis, principal component analysis and regression analysis. A mathematical model has been built for measuring and predicting the level of technical pregress. The result of calculation based on the data provided by Tianjin Construction Committee is quite close to the actual condition. The feasibility of this method is thus confirmed. |
