笔者在建立评价指标体系的基础上,运用灰色关联分析法,构建了人口结构与区域经济交互作用的关联度模型,并对内蒙古人口结构与区域经济发展的关联因素进行了分析。发现内蒙古自治区不同的人口结构对区域经济发展有不同的影响。反之,区域经济的发展促使人口结构发生变化,向适应和促进区域经济发展方向变化。 Based on the establishment of the evaluation index system, the author constructs a correlation model between population structure and regional economic interaction by using gray relational analysis, and analyzes the related factors of population structure and regional economic development in Inner Mongolia. It is found that different demographic structures in Inner Mongolia have different impacts on the development of regional economy. On the contrary, the development of regional economy has led to changes in the demographic structure and changes in the direction of adapting to and promoting regional economic development.
