美丽中国系统耦合协调度的空间异质性探索

Spatial Heterogeneity of the Coupling Coordination Degree of Beautiful China System

美丽中国建设是实现中国梦的重要途径,美丽中国既要富强民主文明,也要人与自然和谐共生。文章应用区域发展理论和耦合协调模型,探讨2013—2017年美丽中国5个子系统的耦合协调度,得出以下结论:(1)2013—2017年,中国大陆各省域美丽中国系统间的耦合度高,系统相关性强;(2)耦合协调度水平在研究期内整体呈现上升趋势,空间异质性明显;(3)耦合协调度5年间始终呈现空间集聚分布,具有空间溢出效应;(4)生态建设始终是美丽中国系统协调发展最大的贡献因子,"高质量"经济建设对耦合协调度的贡献有待提高。

Building Beautiful China is an important way to realize the Chinese dream.Beautiful China should not only be prosperous,strong,democratic and civilized,but also be harmonious with nature.Based on the regional development theory and the coupling coordination model,this paper discussed the coupling coordination degree of five subsystems of Beautiful China from 2013 to 2017,and drawed the following conclusions:1)There was a high degree of coupling and strong system correlation among Beautiful China systems in the provinces of China's Mainland from 2013 to 2017.2)The level of coupling coordination showed an upward trend during the study period,and the spatial heterogeneity was obvious.3)The coupling coordination degree presented a spatial agglomeration and spillover effect from 2013 to 2017.4)Ecological construction has always been the biggest contribution factor to the coordinated development of Beautiful China system,and the contribution of"high-quality"economic construction to the coupling coordination degree needs to be improved.Applying the method of coupling coordination degree to the study on the systematic coordination of Beautiful China can theoretically enhances the academic research value of Beautiful China.In practice,it provides a scientific basis for the coordinated development of Beautiful China and the realization of high-quality regional development.
