摘　　要：基于城际铁路规划建设不同阶段进行场景划分,利用空间公平效率相关模型,选取加权平均出行时间、经济潜力指数、变异系数作为评价指标,对无城际铁路、现状城际铁路及规划城际铁路场景下深莞惠区域空间公平效率变化进行实证分析,进而探讨基于城际铁路规划建设实现区域空间公平效率兼顾的发展模式。研究表明:1)深莞惠城际铁路规划建设有效促进可达性整体提升,沿线地区经济发展潜力提升幅度远高于非沿线地区;2)深莞惠区域核心增长极地位持续增强,城际铁路规划建设大幅提升深圳的经济辐射能力,但同时区域发展不平衡现象也不断加剧;3)深莞惠区域空间公平性格局在城际铁路规划建设影响下呈现中西部高、两翼低的特征,东莞西部沿海地区及惠州东北部地区获益较少;4)城际铁路规划建设促使深莞惠区域形成更为均衡的经济联系格局,临深地区空间公平性改善幅度较大。深莞惠区域在提升交通网络经济效益的同时也应当兼顾资源配置的公平性,推动深莞惠空间结构持续优化、均衡发展。Intercity rail planning and construction generates improved regional accessibility and contributes to changes in the spatial organization of the region,incorporating more areas into the'integrated corridor economy'through the increased attractiveness of new connection locations in a dynamic process involving multi-level impacts in social and economic domains.In addition,the development of areas outside the intercity rail corridor could also be altered by new intercity rail plans;these improvements,often referred to as efficiency impacts,are mainly related to accessibility benefits.Traditional assessment methods do not address the conflicts between efficiency and equity concerns.Achieving a single efficiency objective would bias intercity rail planning towards providing efficient connections between major centers of economic activity,negatively impacting spatial equity as it would lead to polarized spatial development patterns.Equity considerations are receiving increasing attention in current regional transport planning studies,in which intercity rail planning needs to maximize economic growth while maintaining an acceptable level of equity.We divided the scenarios based on different stages of intercity railway planning and construction,built the model of spatial equity and efficiency,adopted weighted average travel time,potential accessibility,and coefficient of variation as evaluation indexes,and conducted an empirical analysis of the changes in spatial equity and efficiency in the Shenzhen-Dongguan-Huizhou region under the scenarios of no intercity railway,current intercity railway,and planned intercity railway,to discuss the development of an equitable and efficient regional spatial model through intercity railway planning and construction.The findings indicate that:Firstly,the planning of intercity railways in Shenzhen-Dongguan-Huizhou region effectively promotes the overall improvement of accessibility,and the economic development potential of the areas along the routes is much higher than that of areas not
