针对面板数据灰色关联模型中存在的一些问题．首先提出了面板数据的初始化方法，用网格法描述面板数据在三维空间中的几何特性．然后将网格拆分为线段，利用线段在空间中的斜率，构建网格关联系数．进而根据算数平均得到灰色网格关联度模型，并讨论了该模型的性质．最后通过算例验证了该方法的可行性与有效性，结果表明灰色网格关联度模型具有良好效果．

According to some problems in the grey incidence for panel data, the panel data initialization method is put forward firstly. Using the grid method, we describe the geometric characteristics of the panel data in three dimensions, and split the grid into line. Then based on the slope of the line in space, a grid incidence coefficient is constructed. Through the arithmetic average, we obtain grey grid incidence model, and discuss the nature of this model. Lastly an example verifies the feasibility and effectiveness of this method, and the results show that grey grid incidence model has good effects.
