| 摘 要： | 运用主成分分析手段，对贵州省51家企业的持续改进行为主要动力的重要性做了归纳推断，发现第一主成分所对应的特征向量各元素基本上能够反映出调查的CI动力因子的重要程度，然后再运用期望值法作出经验上的判断与理论上的推导以及图表对比分析，进一步确证了第一主成分在因子的重要性方面有一定的判断作用。

| Abstract: | The paper analyzes the investigation datum of 51 enterprises in Guizhou is analyzed in this paper, and the importance of main power in sustainable innovation actions is deduced with the method of principal component analysis. Every element in Eigenvector corresponding to the first principal component shows up the importance of CI power factors. The method of mathematical expectation is used to estimate the rational explanation from experience, which has corroborated that the coefficient of first principal component can reflect the importance of factors. Basing on the investigated datum, diagram-matically comparative analysis is given. |
