Study On The Spatial Structure And Economic Effect Of High-Speed Railway To Beijing-Tianjin-Hebei Agglomeration

The construction of infrastructure dominated by high-speed rail has led to the transformation of urban forms within the region,a phenomenon that is universal in the world.Inter-regional transport infrastructure interoperability has become a key factor in achieving truly synergistic regional development across multiple jurisdictions.Through the second half of the twentieth century,since the founding of the planned economy after the founding of new China and the transition to a market economy,the construction of transport infrastructure has always been regarded as an important project concerning the lifeline of the country.Especially with the advent of the transitional period of the market economy,in the great transformation from the era of Ordinary Railways to the era of high-speed railways,both urban agglomerations and cities have taken an important evolution in urban form.The transport infrastructure represented by the railway has always been regarded as an important project that has an impact on the development of China's cities and regions.As an important mode of travel,high-speed railway not only supports large-scale and long-distance and cross-regional large-scale travel at the national scale,but also is an urban group standard,becoming an indispensable way to support daily commuting among cities.From a regional point of view,the construction of transportation infrastructure represented by high-speed railway has changed people-'s travel while making the transformation of the urban agglomeration's spatial structure averted.Taking the Beijing-Tianjin-Hebei urban agglomeration as an example,this paper mainly uses social network analysis and GIS-based situational analysis to analyze the reachability changes of Beijing-Tianjin-Hebei area based on railway network before and after the launch of HSR,The Influence of Space Structure in Ji Cheng Group.The article starts with the study of the impact of high-speed raillways on the spatial structure of the region and uses Beijing-Tianjin-Hebei urban agglomeration as an example to conduct research.Through the reading of a large amount of literature,it combs out valuable information on the articles and makes relevant concepts.Explained.In accordance with the changes in the accessibility of transport-the evolution of spatial organizational structure-the impact of urban and regional economies,this idea is to arrange the content of articles.Through the daily reachability and weighted average arrival time,the accessibility is studied,and through the division of isochronous zones in the region,the influence of daily accessibility in the region is further studied.The opening of the high-speed railway to the Beijing-Tianjin-Hebei urban agglomeration The level of accessibility has greatry improved.After the opening of the high-speed rail,eight cities were included in the one-day circulation circle of the Beijing-Tianjin-Hebei urban agglomeration,which linked the cities within the region more closel,which is beneficial to the regional economy of the Beijing-Tianjin-Hebei region.Integrated and coordinated development;for the study of spatial structure,using social network analysis combined with GIS software,each city has increased its ability to receive radiation from other cities and to radiate other cities by comparing diferent indicators before and after the opening of high-speed rails.The links between regions are closer and the urban spatial structure is optimized.From the perspective of the overall spatial structure,the spatial structure of the Beijing-Tianjin-Hebei urban agglomeration under the irnfluence of the opening of the high-speed railway shows a "multi-center" pattern to the change in the "?"-shaped spatial structure;The impact of railway opening on regional economic effects is mainly based on the study of GDP per capita and the gap between urban and rural areas.In the short term,the high-speed railways in the Beijing-Tianjin-Hebei region have been successively opened,which will have a great effect on the economic growth of Beijing-Tianjin-Hebei urban agglomeration.There is a positive impact on GDP per capita growth rate in the region,but with regard to regional differences,with the opening of the high-speed rail,there may be a trend of further expansion;finally,conclusions and improvements are made.
