组合评价模型在城市综合经济实力评价中应用

针对单一评价方法用于复杂经济系统评价存在的不足,提出了一种新的更有效的经济系统评价方法——组合评价模型。组合评价模型通过组合多个单一模型的评价结果,能够有效地发挥单一方法的优点,弥补单一方法的不足,提高评价的全面性、科学性和合理性。利用广东省2005年的有关统计数据,分别采用综合指数法、主成分分析法、TOPSIS法和熵值法,对珠三角九城市的综合经济实力进行了综合评价和排位;在此基础上,建立基于模糊Borda法的组合评价模型,并对珠三角九城市重新进行了综合评价和排位,取得了更为可信的评价结果。

Application of combination evaluation for cities'''' comprehensive economic power of delta of Pearl River

In view of the weaknesses of simplex evaluation method for complex economic system evaluation, a new and more effective economic system evaluation method called combination evaluation (CE) model is developed in this paper. CE can remarkably improve the evaluation ability through combining multiple simplex evaluation methods' results and take the full use of their advantages meanwhile overcoming their shortcomings to some degree. Using the relevant data of Guangdong province in 2005, composite indexes method, principal component analysis (PCA), TOPSIS and entropy method are introduced to evaluate and sort the comprehensive economic power of nine cities of the delta of Pearl River. What's more, the fuzzy Borda combination evaluation model is constructed to do the same work and a more all-sided, scientific and rational conclusion is drawn.
