【摘要】：从沿线城市加权平均旅行时间和中心城市"小时经济圈"两个维度分析高铁开通对中国城市可达性的影响,利用引力模型、区位优势潜力模型、Moran指数等研究高铁开通对区域经济发展空间格局的影响。研究表明:高铁开通显著改善了沿线城市日常可达性;高铁开通后33个沿线城市对中国261个地级市的"加权平均旅行时间"均值降低;东中西三大区域的城市交通发展不平衡性有小幅度改善;北京、武汉"小时经济圈"呈"面状蔓延"模式,上海、广州、西安的"小时经济圈"呈"轴线扩展"模式。高铁开通显著影响中国区域经济发展格局:沿线城市可达性水平提高,城市间经济联系更加密切,二线城市间经济联系强度增长率最高;长三角城市群区位优势最突出,长江中游城市群潜力巨大;高铁带来的扩散效应增强。最后,本文就依托高铁建设推动中国区域经济健康发展展开了进一步的讨论。
[Abstract]:Based on the weighted average travel time of the cities along the route and the "hourly economic circle" of the central city, this paper analyzes the impact of the opening of high-speed rail on the accessibility of Chinese cities, and makes use of the gravity model. The location advantage potential model and Moran index are used to study the influence of the opening of high-speed rail on the spatial pattern of regional economic development. The results show that the opening of high-speed railway has significantly improved the daily accessibility of cities along the route, and the weighted average travel time of the 33 cities along the route has decreased to 261 prefecture-level cities in China after the opening of high-speed rail. The imbalance of urban traffic development in the three major regions of East, West and East has been improved by a small margin; the "hourly economic circle" in Beijing and Wuhan is "spreading in a plane" mode, and the "hourly economic circle" in Shanghai, Guangzhou and Xi'an is an "axis expansion" mode. The opening of high-speed rail significantly affects the pattern of regional economic development in China: the accessibility level of cities along the route is improved, the economic links between cities are closer, the growth rate of economic links between second-tier cities is the highest, and the location advantages of urban agglomerations in the Yangtze River Delta are the most prominent. The potential of urban agglomeration in the middle reaches of the Yangtze River is great; the diffusion effect of high-speed rail is enhanced. Finally, this paper further discusses how to promote the healthy development of China's regional economy by relying on the construction of high-speed railway.
