It was frist used for the measurement of the change of prices and now it is not only the tool for the analysis of evaluation of life quality, service quality and product quality, etc.In the building industry, appraisal of projects'quality and statistical indicators are relatively backward and an advanced system to refloot the quality status of construction projection is needed for regular analyzing, judging and integrating the data got from the inspection. Thus this paper uses quality index system as way to intergrate the information got from the government or relative party's supervision of the constuction quality.Based on the research of the quality indices, which is a general meaning, both in the literature and in practice, the paper investigates and analyses the methods for the establishment of indices with discussion of the relationship between the quality index and economic indicators, the choice of the weights, base period and release cycle, and the testing theory.
