基于主成分聚类的工程承包商国际化程度评价

Evaluation of Engineering Contractors Internationalization Based on Principal Composition Cluster Analysis

在总结以往评价理论后,将主成分法与聚类结合,建立了一套科学适用的工程承包商国际化程度评价模型,分析2013年度ENR250中9家承包商,和主成分法、第一主成分法比较。结果表明,主成分聚类法能对企业进行排名和分类,客观反映企业发展事实,为国际化程度评价提供了新的视角。

The theories are analyzed based on previous reviews,a scientific and applicable evaluation model for the internationalization of engineering contractors combining Principal Component Analysis（ PCA） and clustering is set up,and the 9 Engineering Contractors of the 2013 annual ENR250 are analyzed. This method is also compared with PCA and the first principal component method. It is shown that Principal Component Clustering Analysis can not only rank the enterprises,but also classify the enterprises. The results are in accordance with the facts. A new perspective is provided to evaluate the engineering contractors internationalization.
