Comparison of urban networks by Baidu index and gravity model:a study of Jing-Jin-Ji urban agglomeration
摘要
Abstract
Urban network has become important to analyze interactions and flow patterns among urban agglomerations.Distribution of urban grade and network structure characteristics were compared between traditional geographical gravity model and information age method of Baidu index for urban network of the JingJin-Ji urban agglomeration.Comparative study found that the center of Beijing in Baidu index network presents a starlike diffusion mode.Gravity model network exhibits a diffusion model with Beijing and Tianjin as two cores The gravity model network has little change in different time nodes,while response of Baidu index network to time and function of city is more obvious.According to radio difference in total connection value of cities in the two models,cities can be classified as virtual space oriented cities (Shijiazhuang,Baoding,Qinhuangdao,Zhangjiakou,Chengde),physical space oriented cities (Tianjin,Tangshan,Langfang,Cangzhou),and physical virtual balanced cities (Beijing,Handan,Xingtai and Hengshui).关键词
