以东北地区34个地级市为研究对象,利用灰色关联模型和耦合度模型,对东北地区人口结构与经济发展的耦合关系进行分析,结果表明:(1)人口结构与经济发展整体处于中高等关联水平,人口文化素质和城市化水平对东北地区经济发展的驱动作用明显;(2)自2000年以来,东北地区人口结构与经济发展耦合关系整体经历了波动上升、平稳下降、缓慢上升的过程;(3)人口结构与经济发展相互影响、相互制约,在经济发展的不同阶段,经济发展与人口结构均处于协调发展状态,但是协调水平高低不同;(4)各省人口结构与经济发展耦合度变化差异较大,辽宁省两系统的耦合度呈现出与整个东北地区大致相同的变化趋势。
Taking the 34 prefecture-level cities in Northeast China as the research object, this paper analyzes the coupling relationship between population structure and economic development in Northeast China by using the gray relational model and the coupling degree model. The results show that: (1) Population structure and economic development are generally in the higher (2) Since 2000, the coupling relationship between population structure and economic development in Northeast China has undergone an overall ups and downs, a steady decline and a slowly rising process ; (3) Population structure and economic development interact with each other and restrict each other; at different stages of economic development, both economic development and population structure are in a state of coordinated development, but the level of coordination is different; (4) Coupling degree of population structure with economic development The differences between the two systems vary greatly, and the coupling degree between the two systems in Liaoning Province shows the same trend as that in the entire Northeast China.
