| At present,logistics integration has become an important part of regional economic development and regional logistics development under the background of economic globalization and integration of Beijing,Tianjin and Hebei.For regional logistics integration,efficient and convenient logistics network is an important driving force.Therefore,constructing a reasonable and scientific logistics network can not only reduce logistics costs,improve logistics efficiency,but also solve regional logistics development problems.The Beijing-Tianjin-Hebei region is the third growth pole of China's economic growth.Its economic development and logistics level are relatively high.However,compared with the Yangtze River Delta and the Pearl River Delta region,Beijing-Tianjin-Hebei region still has such problems: unbalanced economic development and logistics development,scattered issuses in the logistics center and cargo hub,so it is crucial to optimize the logisticis node cities layout in Beijing-Tianjin-Hebei region.The thesis starts from the related theories of regional logistics network,hub and spoke logistics network and logistics network optimization to seek the theoretical support and analysis methods.The paper deeply analyzes the development status of the logistics industry of the Beijing-Tianjin-Hebei region and summarizes the main problems.After analyzing the roads,railways,aviation and waterway logistics channels of Beijing-Tianjin-Hebei,the paper combined the logistics industry layout to study its logistics network.Through the availability,correlation and sensitivity analysis of indicators,the paper selected the indicators that affect the level of logistics node cities in Beijing-Tianjin-Hebei region.The comprehensive scores and ranking situation of each city node were calculated by means of factor analysis method.The modified gravitational model quantitatively studied the logistics linkage values and their respective integrated logistics development capabilities in this region.Based on the scores,logistics gravity value and social network software,we identified social first-axis cities: Beijing,Tianjin,Shijiazhuang,Tangshan,Langfang,secondary axis cities: Cangzhou,Baoding,Handan,Xingtai,Qinhuangdao,Hengshui,and third-level cities: Chengde and Zhangjiakou.Combined with the industrial layout of Beijing-Tianjin-Hebei,we obtained radiating Baoding,Chengde and Zhangjiakou of Beijing logistics circle,radiating Cangzhou of Tianjin logistics circle,radiating Handan and Xingtai of Shijiazhuang logistics circle,radiating Qinhuangdao of Tangshan logistics circle and radiating Hengshui of Langfang logistics circle.Relevant countermeasures for their respective logistics circles were proposed and the logistics node cities have been optimized to provide theoretical guidance for the development of the Beijing-Tianjin-Hebei regional logistics network. |
