摘  要:国家经济的持续发展,对京津冀地区的产业布局有巨大的影响。文章通过区位熵分析京津冀城市的物流产业集聚情况,汇总高铁开通前后京津冀区域13个城市之间的最短交通时间。运用区域可达性模型分析各个城市的加权平均旅行时间,并将收集的数据进行回归分析。结合灰色预测模型分析高铁开通前后京津冀物流产业集聚的变化率。结果表明:高铁开通,提升了城市的可达性,促进了城市物流产业的集聚,有效促进了京津冀经济的增长。

Abstract: The development of the national economy has an impact on the industrial layout of Beijing-Tianjin-Hebei. This paper analyzes the agglomeration of the logistics industry in Beijing-Tianjin-Hebei cities by location entropy, and summarizes the shortest transportation time between the 13 cities in Beijing-Tianjin-Hebei before and after the opening of high-speed rail. The weighted average travel time of each city is analyzed by using regional accessibility model, and the collected data are analyzed by regression analysis. An analysis of the change rate of Beijing-Tianjin-Hebei logistics industry agglomeration before and after the opening of high-speed rail by grey prediction model. The results show that: the opening of high-speed rail improves the accessibility of the city, promotes the agglomeration of urban logistics industry, and effectively promotes the economic growth of Beijing-Tianjin-Hebei.

Key words: high-speed rail; regional accessibility; grey model; logistics industry agglomeration

2019年底,我国高铁营业里程为3.5万公里,目前约占全世界高铁总里程的70%,在促进京津冀地区的产业协同发展中,高铁的建设对于未来京津冀地区物流业的发展有重要的意义,因此探究高铁对京津冀城市群物流业集聚的影响,有助于城市群的协调发展。目前,高铁开通对沿线区域产业集聚的影响研究主要集中在两个方面,即高铁对延伸产业和衍生产业的集聚影响。一方面,高铁对延伸产业集聚的影响,纪玉俊(2020)等[1]将高铁建设的现实情况与新经济地理学的理论模型相结合,从劳动力流动视角构建高铁建设影响制造业集聚的综合分析框架。张卫东(2020)等[2]通过分析成渝城市群在高铁建设和开通时期产业结构的变化,发现高铁会促进第二、三产业经济增长。另一方面,高铁对衍生产业集聚影响,国内外学者认为高铁开通会提升城市的可达性,Jingjuan Jiao(2020)等[3]通过可达性和连通性评估高铁发展所带来的区位禀赋特征和空间相互依赖效应。……
