摘要
为厘清交通基础设施投资与区域经济的耦合协调关系及时空演变格局,在构建交通基础设施投资与经济发展综合评价指标体系的基础上,引用熵权法、耦合度及耦合协调度模型对湖北省及其17个地市州的交通基础设施投资与经济发展耦合关系和耦合协调发展程度的时空特征进行分析。结果表明:2001—2019年,湖北省交通基础设施投资与经济发展2个子系统的耦合度一直处在较高水平,耦合协调度表现出持续稳步上升的良好趋势;2019年,湖北省各地市州交通基础设施投资与经济发展2个子系统的耦合度、耦合协调度整体水平偏低,且存在较为显著的空间差异性。本研究实证了交通基础设施投资与经济发展存在交互耦合、协调互动的关系。
This study aims to clarify the coupling coordination relationship between transportation infrastructure investment and regional economy and its spatiotemporal evolution patterns. After the construction of comprehensive evaluation index systems of transportation infrastructure investment and economic development, the research targets in Hubei Province and 17 prefecturelevel administrative regions were analyzed with the entropy weight method, coupling degree and coupling coordination model. The results show that the coupling degree between the two subsystems of transportation infrastructure investment and economic development in Hubei Province remained at a high level from 2001 to 2019, and the coupling coordination degree rose steadily. In 2019, the overall coupling degree and coupling coordination degree between the two subsystems were low in the 17 prefecture-level administrative regions, accompanied with significant spatial differences. This study demonstrates the interactive coupling and coordinated interaction between transportation infrastructure investment and economic development.
