四川省县域交通优势度与经济发展耦合协调度分析

交通优势度是区域经济发展的重要支撑，通过观测区域交通优势度与经济发展耦合协调度的空间分布特征，可揭示区域交通与经济发展间不平衡与不充分的矛盾，从而为区域交通规划与建设提供科学依据。采集四川省183个区县交通与经济发展的相关指标，测算县域交通优势度和经济发展水平的耦合协调度，可以观察到四川县域交通与经济耦合协调度呈现出以成都平原经济区为核心逐渐向外围减弱以及东高西低的空间分布特征。

Analysis of Coupling Coordination Degree between Traffic Superiority Degree and Economic Development in Counties of Sichuan Province

Traffic superiority is an important support for regional economic development. By observing the spatial distribution characteristics of the coupling coordination between regional traffic superiority and economic development, the imbalance and insufficient contradiction between regional traffic and economic development can be revealed, thus providing scientific basis for regional traffic planning and construction. By collecting the relevant indicators of traffic and economic development in 183 districts and counties in Sichuan Province is collected, and calculating the coupling coordination degree of county traffic superiority and economic development level is calculate. It can be observed that the coupling coordination degree of traffic and economy in Sichuan counties shows the spatial distribution characteristics of gradually weakening to the periphery with Chengdu Plain Economic Zone as the core and being high in the east and low in the west.
