| 摘 要： | 关中平原城市群是丝绸之路经济带的重要城市群。运用耦合协调度模型定量分析了关中平原城市群2008—2019年交通、产业和环境三系统耦合协调发展关系的变化规律和时空分布特征。结果表明：（1） 城市群交通、产业和环境各子系统发展评价指数差异化提升,交通系统发展增长率远超过其他两系统,产业和环境发展与交通系统的矛盾较为突出。（2） 三系统综合发展指数空间分布单极态势明显,城间发展水平差异加剧,其中西安市和咸阳市作为极热点城市存在,其余城市为外围受辐射冷点区。（3） 城市群耦合协调发展水平整体上趋于优化提升态势,但仍处于濒临失调状态。其中,西安市一直处于高耦合协调的单极态势,但耦合协调度的城间差距逐渐缩小,耦合协调度等级为协调等级的城市逐渐增多,趋于集中连片式分布。研究结果可以明确关中平原城市群交通、产业和环境三系统耦合协调发展存在的问题,为高质量发展相关政策的制定提供一定的参考依据。

| Abstract: | This study uses the entropy weight method and coupling coordination model to explore the change law and temporal and spatial distribution characteristics of the coupling and coordinated development relationship of transportation, industry, and the environment in Guanzhong Plain urban agglomeration of China from 2008 to 2019. This study uses panel data of the transportation, industrial, and environmental systems of 11 central cities in Guanzhong Plain urban agglomeration and proposes a theoretical reference for further improving the high-quality development of Guanzhong Plain urban agglomeration. The results show that (1) the development evaluation indexes of transportation, industry, and environment subsystems of urban agglomeration are differentiated, the development growth rate of the transportation system is much higher than that of the other two systems, and the contradiction between industrial and environmental development and the transportation system is more prominent. (2) The spatial distribution of the comprehensive development index of the three systems has an obvious unipolar trend, and the difference in the development level between cities has intensified. Xi’an and Xianyang City exist as extremely hot cities, and the other cities are peripheral radiation cold spots. (3) The coupling and coordinated development level of urban agglomeration tends to be optimized and improved overall, but tending toward imbalance. Among them, Xi’an City has been in a unipolar situation of high coupling and coordination, but the gap between the cities in coupling and coordination has gradually narrowed, and the number of cities with coupling and coordination has gradually increased, tending to be concentrated and distributed. Therefore, to realize the high-quality development of Guanzhong Plain urban agglomeration, it is necessary to first actively build a spatial development pattern of “one circle, one axis, and three belts,” promote the construction of a high-speed railway, build a rapid transportation network, and change the current development characteristics of traffic lag. Second, it is necessary to strengthen the radiation driving role of central cities and gradually reduce the differences in the coupling and coordinated development level of regional transportation, industry, and environment. This study plugs the gap in existing research on Guanzhong Plain urban agglomeration, a national urban agglomeration under the new orientation of reform and opening up, and places transportation, industry, and environment in the same system, breaking through the research on the one-way relationship between each two systems. |
