摘要
针对中心城市可达性在区域非中心城市经济增长体系中的定量影响效应尚不明确的问题,以成渝地区双城经济圈为研究范围,将成都市与重庆主城区作为区域中心城市,基于2010—2019年城市统计年鉴数据与高速公路网络、铁路网络GIS数据等,通过空间计量模型评价了中心城市的带动效应现状,提出了非中心城市与中心城市两者间可达性测度方法,构建了考虑中心城市可达性的城市经济增长的结构方程模型.研究结果表明:中心城市对成渝地区双城经济圈非中心城市尚未发挥显著的正向带动作用,并加剧了区域发展不平衡的现状;考虑中心城市可达性影响提高了模型的整体适配度,使城市经济增长的理论框架更加完善;加强城市自身交通水平对促进资本投入具有直接影响效应,但无法直接对人才与技术要素产生影响;产业发展是影响城市经济增长的最直接且影响程度最大的要素,资本水平是城市经济增长的关键中介因素.城市资本水平的提高可促进人才流入与技术进步,带动城市产业与经济发展;提高中心城市可达性是多种经济增长要素的直接驱动力,既可促进城市自身交通水平的发展,还为城市带来了人才、资本与技术等经济发展关键要素.
To address the unclear quantitative influence of the accessibility for central cities in the eco⁃nomic growth system of regional non-central cities,this paper takes the twin-city economic circle of Chengdu and Chongqing region as the scope of research.Taking Chengdu and the main urban areas of Chongqing as regional central cities,and using data from the 2010-2019 City Statistical Yearbook,as well as GIS data of the highway and railway networks,a spatial econometric model is employed to evaluate the current state of the driving effects for the central cities.Additionally,a measurement method for the accessibility between non-central cities and central cities is proposed,and a structural equation model of urban economic growth considering the accessibility of central cities is constructed.The research findings indicate that the central cities have not yet exerted a significant positive driving effect on the non-central cities within the Chengdu-Chongqing twin-city economic circle,and exacer⁃bated regional development imbalances.Considering that the influence of the central city accessibility improves the overall fitness of the model,and improves the theoretical framework of urban economic growth.Strengthening the transportation level of cities has a direct impact on promoting capital invest⁃ment,but it does not directly affect talent and technical factors.Industrial development is the most di⁃rect and influential factor affecting growth,and the level of capital is a key mediator of urban economic growth.Enhancing the capital level of cities can stimulate talent inflow and technological progress,thus driving the development of urban industry and economy.Improving the accessibility of central cit⁃ies is a direct driving force for various economic growth factors,promoting both the development of ur⁃ban transportation level and attracting key elements for economic development,such as talent,capi⁃tal,and technology.
