哈长城市群人口与经济发展协调关系研究

Research on the Coordinated Relationship between Population and Economic Development in Harbin-Changchun Urban Agglomeration

摘要: 探究哈长城市群人口与经济发展的协调关系对于推动其健康发展有重要意义。选取1990、2000、2010和2020年的人口及经济数据，计算人口、经济地理集中度和人口、经济增长率分析群内城市人口与经济变化，运用人口经济一致性系数与人口–经济增长弹性系数探究群内人口与经济发展协调关系。结果表明：①人口、经济地理集中度在空间分布上存在相关性和差异性，研究期内人口经济一致性差异有减小趋势。② 1990~2020年仅长春、哈尔滨和大庆人口增长，其余城市均表现为人口收缩；长春经济增速最快，其次为哈尔滨。各时间段人口与经济增长空间分布及变化存在较大差异。③ 1990~2020年松原与辽源人口与经济增长协调性最好。前两阶段群内城市均处于社会协调发展级，最后阶段出现社会渐进级城市。

Abstract: Exploring the coordinated relationship between population and economic development in Harbin-Changchun urban agglomeration is of great significance for promoting its healthy development. Select population and economic data from 1990, 2000, 2010, and 2020, calculate population, economic geographic concentration, and population and economic growth rates to analyze the changes in urban population and economy within the group. Use the population economic consistency coefficient and population economic growth elasticity coefficient to explore the coordinated relationship between population and economic development within the group. The results indicate that: ① There is a correlation and difference in spatial distribution between population and economic geographic concentration, and the difference in population economic consistency has a decreasing trend during the study period. ② From 1990 to 2020, only Changchun, Harbin, and Daqing experienced population growth, while the rest of the cities showed population contraction; Changchun has the fastest economic growth rate, followed by Harbin. There are significant differences in the spatial distribution and changes of population and economic growth in different time periods. ③ The population and economic growth coordination between Songyuan and Liaoyuan was the best from 1990 to 2020. In the first two stages, cities within the cluster are all at the level of social coordinated development, and in the final stage, there are cities at the level of social gradual development.
