摘　　要：以外向型行业从业人口为联系指标、列车通行耗时为距离构建引力模型,分析2007—2019年京津冀地区城市联系强度及变化情况。结果表明:高铁网络促进了京津冀城市间的联系,但域内中转环节较多且集中在外向型产业强劲的京、津,其他城市联系强度普遍较弱,“二元结构”特征明显;京津冀城市联系趋向紧密,且存在一定非对称性;京津冀城市联系强度与迁徙指数相关系数整体较高,京、津两市城市联系强度计算结果存在一定高估。In this paper,a gravity model was established with the population of exportoriented industries as the correlation index and the train travel time as the distance.The intensity and change of urban connections in the Beijing-Tianjin-Hebei region from 2007 to 2019 were analyzed.The results show that:The high-speed rail network promotes the connection between Beijing,Tianjin and Hebei,but there are more intraregional transit links and concentrated in Beijing and Tianjin with strong exportoriented industries.The connection strength of other cities is generally weak,and the characteristics of"dual structure"are obvious.Beijing-Tianjin-Hebei urban linkages tend to be close,and there is a certain asymmetry.The correlation coefficient between Beijing-Tianjin-Hebei urban connection strength and migration index is relatively high on the whole,and the calculation results of urban connection strength of Beijing and Tianjin are overestimated.
