天津自贸区与京津冀区域经济耦合协调度研究

Study on Coupling Coordination of Tianjin Free Trade Zone and Beijing-Tianjin-Hebei Regional Economy

文章基于耦合理论,剖析天津自贸区与京津冀区域经济的耦合协调机理,构建了两系统间的耦合协调评价体系。通过2015~2019年京津冀地区的统计数据,实证分析了两系统间耦合协调度的时空演化过程。研究结果发现:2015~2019年间天津自贸区与京津冀区域耦合度和耦合协调度均呈现上升趋势,从设立之初的严重失调发展到了优质协调状态;天津自贸区与京津冀区域的经济在新冠肺炎疫情冲击下并未受到太大影响,综合发展指数依然保持着增长趋势。

The coupling coordination mechanisms of the Tianjin Free Trade Zone and the Beijing-Tianjin-Hebei regional economy were analyzed with coupling theory,and the coupling coordination evaluation system was established.The spatiotemporal evolution process of the coupling coordination between the two systems was empirically analyzed using statistical data from the Beijing-Tianjin-Hebei region from 2015 to 2019.The result showed that the degree of coupling and coordination between Tianjin Free Trade Zone and the Beijing-Tianjin-Hebei region both increased from 2015 to 2019,from a state of serious imbalance at the start of its establishment to a state of high-quality coordination.Tianjin Free Trade Zone and the Beijing-Tianjin-Hebei region were not affected too much by the COVID-19 epidemic,and the comprehensive development index remains positive.
