建设领域信息化水平测度方法研究

根据中国建设领域信息化发展的需要，对信息化水平测度的方法进行了研究。笔认为，综合指标体系与关键单指标测度结合，是认识中国建设领域信息化水平的有效途径。提出以恩格尔系数法、增量效益分析法与平均GNP法作为关键单指标分析方法，同时建立了包括软指标与硬指标的综合指标评价模型，并给出了估计综合指标评价权重最优赋权法。

Study on Measures of Informationization Level in Construction Field

According to the development of informationization in Chinese construction field, this paper researches methods to measure the level of informationization, and suggests it is an effective idea to integrate single index way to comprehensive index way to understand informationization level of Chinese construction field. So the paper introduces Engel coefficient method, increment benefit method and average GNP method into key index of measures, and establishes a comprehensive index model including soft indexes and rigid indexes as well as optimization method to weight every index in the general model.
