基于灰色系统理论，分析了影响系统特征序列与系统相关序列的灰色关联度的因素。构建了一个基于序列曲线几何形状间的相似性和相近性的灰色关联度模型，并分析了模型的规范性、对称性、保序性及正负相关性等。将该模型与已有模型进行比较分析，实例分析结果表明，该模型的分析结果客观可靠，该模型在经济预测等方面具有良好的应用性。

Based on the grey system theory,this paper analyzes the influencing factors of grey correlation degree between the sequence of sys tem character and the sequence of system correlation. And it constructs a grey correlation model based on the theory of comparability and prox imity, and analyzes the property of this model, such as standardization, symmetry,preservation, and positive and negative correlation between se quences etc. Through contrasting with some existed models and the example analysis,the result shows that the result based on this model is ob jective, and this model is reliable and applicable in economic forecast.
