选取2001—2018年我国各城市数据多方面测度长三角城市群城镇化,运用首位度、多时点DID模型等分析高铁开通对城镇化的影响,并通过中介效应模型检验其影响机制.结果显示:长三角城镇化首位度符合“位序—规模”规律,高铁开通对城镇化首位度产生影响;高铁开通后区域城镇化空间结构向多中心转变,呈由东向西递减趋势,沿海、内陆城市差异显著.高铁开通对城市群城镇化空间结构产生负效应,在三四线城市尤为显著;中介效应检验发现产业结构升级有利于城镇化空间结构的优化升级,高铁开通主要通过抑制产业结构升级来阻碍城镇化空间结构优化升级.

“两路”精神缘于20世纪50年代川藏公路和青藏公路的修建,其有形载体是中国精神传承的优秀红色资源之一,对红色基因传承具有重大意义.当前承载“两路”精神的有形载体现状不容乐观,存在被淡化、遗忘、消失的危险.“两路”精神的传承停留在研究层面,未能在现实中形成影响,学者们对“两路”精神有形载体的研究较少,对“两路”精神有形载体的保护性措施研究不足,研究这一问题具有抢救性突出意义.
