引入相似关联度来代替绝对关联度，与相对关联度进行耦合，构建改进灰色综合关联度，试图兼顾各序列曲线几何形状的相似程度、各序列相对于始点变化速率的接近程度，并扩大了传统灰色综合关联度的适用范围，以此来测定影响我国物流业发展的关键因子，认为其主要包括货运量、固定资产投资等。

In this paper, we introduced the approximate correlativity to replace the absolute correlativity to improve the comprehensive grey correlatioin model, which attempted to cover both the level of similarity between the geometric shapes of different sequential curves and the proximity of the change rate of the sequences in relation to their initial points and extended the scope of application of the traditional comprehensive grey correlation model.
