Research on Investment Efficiency for Capital Construction in Coal Mine Based on Principal Component Analysis

Abstract:

In the paper, by designing evaluation system, capital construction investment efficiency of 13 coal mines in Shanxi province is analyzed through using principal component analysis. Meanwhile comprehensive scores of capital construction efficiency are calculated. The highest score and the lowest score are 3.813 and-1.141, respectively. Finally, 13 coal mines are divided into three levels, sufficiently distinguishing capital construction efficiency of those coal mines.
