人口结构与经济发展相互影响、相互制约,两者的协调发展是实现区域可持续发展的重要途径。建立人口结构与经济协调度的评价指标体系、模型和方法,并对辽宁省进行了实证研究。研究表明,1995年以来辽宁省人口结构与经济协调发展呈现“倒u”型曲线:2000年以前,人口结构与经济协调发展状况由初级协调向高级协调转化;2000年以后,两者的协调发展状况却有不断下降的趋势。图2,表4,参12。
The population is the most important issue of sustainable development. The coordinated development of population structure and regional economy is viewed as an important way to achieve regional sustainable development. Coordination degree is a good quanti- tative indicator for measuring the coordinated development of systems or elements. In this paper, we established an evaluation indicator structure to the coordinated development of population structure and regional economy, constructed a coordination degree model by u- sing principal component analysis and correlation analysis and taken Liaoning province as an example, which used to be a typical area of "Northeast phenomenon" in the 1990s. The results show that, the development of population structure and regional economy tends to improve the overall situation during 1995 -2006 in Liaoning Province. The relationship of the coordinated development is in line with the "anti - U shape" curve, and can be clearly divided into tow stages :(1)before 2000, the coordination degree of population structure and regional economy continuously in- creases, from primary coordination stage to higher one. The coordination degree of 1995 - 1999 which is the lowest is 0. 922, and that of 2000 - 2004 reaches the highest. (2) after 2000, a downward trend appears, down to 0. 954 during 2002 - 2006.
