基于生活方式视角的城市青年居民交通出行与居住区位选择行为——以南京市为例

Travel mode choice and residential location choice behavior of urban youth residents based on the concept of lifestyle:A case of Nanjing

引入生活方式概念并作为城市青年居民细分指标,通过构建潜在类别选择模型,探讨青年居民日常交通出行方式及居住区位选择行为。基于调查数据,采用聚类分析将青年居民生活方式分为“市区+个人公共交通+家庭私家车”导向、“市区+个人出行无偏好+家庭私家车”导向、“市区+个人/家庭私家车”导向、“市郊+个人/家庭公共交通”导向、“市郊+个人/家庭私家车”导向,及“市郊+个人公共交通+宅家”导向6种类型。随后基于模型参数估计结果,研究城市青年居民生活方式、出行方式及居住区位选择间的内在联系。相关研究成果与结论为理解城市青年居民时空选择行为差异提供了理论支持。

Constructing a youth-friendly urban environment has emerged as a crucial developmental objective in numerous Chinese cities.However,the financial capacity to sustain urban living and transportation exerts a significant impact on the mental well-being,livelihoods,and work of young residents.Based on this,first of all,we have developed a latent class choice model that incorporates the notion of lifestyle to investigate the intricate relationship between lifestyle choices,daily travel mode preferences,and residential location decisions among urban youths.Then,this study presents a novel instrument for measuring urban youth residents’transport-related and residential-related lifestyles.Subsequently,a comprehensive survey comprising 37 items was developed and conducted in Nanjing from April to June 2022,targeting individuals aged between 25 and 36 years,to gather data encompassing demographic characteristics,travel patterns,and residential location information.Principal component analysis is used to reduce the lifestyle instrument’s 37 items to 8 dimensions.Cluster analysis is applied to identifing 6 classes of urban youths.The final solution has 6 transport-related and residential-related lifestyle segments,which are profiled in terms of relevant background characteristics.Such as:“urban dwelling with personal public transport and family private car orientation”,“urban dwelling with personal travel without preference and family private car orientation”,“urban dwelling with personal and family private car orientation”,“suburb dwelling with personal and family public transport orientation”,“suburb dwelling with personal and family private car orientation”,and“suburb dwelling with personal public transport and staycation orientation”.Finally,utilizing the developed latent class choice model,this study further examines the disparities among various lifestyle segments and investigates the influence of lifestyle on daily travel mode choices and residential location preferences among urban youth residents.The latent class choice model’s parameters estimation results indicate significant differences among each lifestyle segment,which are consistent with the previously identified profiles of the transport-related and residential-related lifestyle segments.Moreover,the parameter estimation results for socio-demographic attributes(referring to vector parameterα),residential location attributes(referring to vector parameterβ),and daily travel mode choice(referring to vector parameterγ)of each lifestyle segment further confirm that urban youth residents’lifestyle choices have a significant influence on their daily travel mode choices and residential location choices.Additionally,incorporating the concept of lifestyle enhances the predictive accuracy of the model.In sum,lifestyle segmentation proves to be a valuable tool for urban managers to understand the disparities and similarities in daily travel mode choices and residential location choices among urban youth residents,and can help urban managers can gain better insights into diverse choice behaviors among young urban residents which can inform effective people-oriented management initiatives.eople-oriented management initiatives.
