主成分线性加权综合评估模型及其在经济系统中的应用

The Linear weighted synthetic Appraisal Model for Main Components and Its Applications in Economic Systems

本文以经济系统为背景,建立了一个对多指标系统进行综合评估的主成分线性加权数学模型,并应用该模型,对广州市越秀区商业、工业各行业和企业按多个经济指标进行综合评估与排序,从中提练出大量有用的信息,为制定越秀区的经济发展战略提供了定量的依据。文中建立的数学模型,可推广应用于其它多指标系统的综合评估中。

In this paper, we establish the linear weighted synthetic appraisal model for main components on multitarget systems and apply this modelto synthetic appraising and ordering according to many economic targets with respect to professions and enterprises of trade and industry of Guangzhou yucxiu District. From them we extract a large quantity of uscful informations. These informations provide a quantitative basis for working out econoic developing strategy of yue xiu District.The mathematical model may be generalized to synthetic appraising on other multitarget sytems.
