在社会经济系统的管理与控制中，判别优势因素是必要的，灰色统计的关联度分析提供了一种多因素优势分析方法，但现有的方法要求条件过于严格，本文认为这在宏观社会经济系统中是没有必要的，同时也影响了该方法的应用。本文提出一种改进的优势分析法，该方法在关联分析的基础上结合了“理想点法”的思想，能适用于一般的多因素优势分析。实际应用表明了该方法的可行性。

In macro socio economic systems, superiority analysis can play an important role in the management and control processe.The existing approach to superiority analysis based on correlation matrix of grey statistics is an approach which was hedged with some basic but unnecessary qualifications. It has been largely restricted in its application.This paper presents an improved approach to superiority analysis formed by combining correlation analysis with the idea of TOPSIS. It is applicable to general superiority analysis problems with many factors. A practical application is provided to show its feasibility and convenience.
