地区生产总值灰色关联预测模型群的研究

Research on Grey Relevancy Prediction Models for Local GDP

生产总值是受多种因素制约的处于动态变化的灰色系统。本文针对多种影响因素,运用灰色关联分析方法确定主因素变量,从而建立灰色关联预测模型GM(1,N)和GM(0,N),并将预测结果与GM(1,1)模型进行协调综合,这样得到的数据更加合理,也大大提高了预测结果的可信度和应用价值。

GDP is a dynamic grey system restricted by many factors.Considering many influencing factors,the primary factors are determined using grey relational analysis,this paper can set up grey relevancy prediction models GM（1,N） and GM（0,N）,and then coordinates and synthesizes the different prediction results to obtain the comparatively logical predicted values.It greatly elevates reliability and application values.
