摘　　要：近年来中国城市群都市圈尺度的跨城通勤现象愈加频繁。相对于国际大城市的通勤圈,国内跨城通勤特征与影响因素仍不明晰。论文以京津冀城市群为例,基于贝壳App租房者的双城通勤位置数据,采用基于GIS的OD(origin-destination)分析与空间统计分析,考察跨城通勤现象的空间分布特征;并辅以个体通勤时间为因变量的普通最小二乘法(ordinary least squares,OLS)、地理加权回归(geographically weighted regression,GWR)模型,揭示空间变量和个人社会属性综合作用下的影响机制。结果表明:①京津冀城市群的跨城通勤呈现出明显的廊道分布特征,集中在东部、东南与西南三条通勤廊道上;②跨城通勤距离已经超越都市圈传统研究聚焦的30~50 km范围;③跨城通勤群体占租房总量20%以上的地区,位于廊坊燕郊开发区、固安县、保定涿州市等地,形成高频通勤的“环京通勤带”;④跨城通勤个体层面的GWR回归显示了职住两地工资差异、租房价格及居住地到高铁站距离等因素对通勤时间具有空间异质性影响。长时间跨城通勤动机存在差异,部分天津跨城通勤者主要为提高居住质量和工资,而部分廊坊、保定通勤者则为了提高工资和节省房租。研究结果可为新型城镇化战略下的城市群都市圈城镇空间合理布局与综合交通协同优化提供借鉴。In recent years,inter-city commuting at the mega-region scale in China is becoming increasingly frequent.Compared to the commuting circles of international mega-cities,the characteristics of inter-city commuting and influencing factors in mega-regions remain to be cleared.Taking the Beijing-Tianjin-Hebei mega-region as an example,this study used origin-destination(OD)analysis and spatial statistical analysis based on GIS to investigate the spatial distribution of inter-city commuting with the location data of twin city commuting of Beike Net renters.Assisted by ordinary least squares(OLS)and geographically weighted regression(GWR)models with individual commuting time as the dependent variable,this study revealed the impact mechanisms under the combined effect of spatial variables and personal social attributes.The analyses showed that:1)The inter-city commuting of the Beijing-Tianjin-Hebei mega-region is evidently along some corridors,concentrated in the east,southeast,and southwest commuting corridors.At the city level,Langfang and Tianjin are the main origins,while at the county level,the main commuting corridor is from the Yanjiao high-tech zone to Beijing urban area.2)The average inter-city commuting distance has exceeded the general metropolitan area boundary of 30-50 km.3)The inter-city commuters account for more than 20%of the total commuting population located in the Yanjiao high-tech zone of Langfang City,Gu'an County,and Zhuozhou of Baoding City,forming a high-frequency commuting area—the Beijing commuter belt.4)The GWR showed that spatial factors such as the difference in housing and salaries between the workplace and residential areas and the distance from the residence to the high-speed rail station have spatial heterogeneity effects on commuting time.The research found that the motivation for long-time inter-city commuting differs between cities.Some commuters in Tianjin are motivated by improving living quality and salaries,while some commuters in Langfang and Baoding are motivated by improving s
