While much research has explored the determinants of car ownership, there is little understanding of these factors in the context of apartment households, where off-street car parking provision is frequently stipulated by planning requirements and zero-car households are more evident. Drawing on a survey of apartment residents (n = 1316) in three Australian cities, this study aimed to understand the determinants of zero-car and car-owning apartment households. The data was analysed using binary and multinominal logistic regression, including random parameter modelling. A joint model of car ownership and off-street car parking supply was also developed to account for potential endogeneity between these two variables. The results highlight the significant association between car ownership and off-street car parking supply, alongside a range of socio-demographics, attitudes, perceptions, built environment and transport characteristics. An additional off-street car parking space, on average, was found to increase the odds of having 2+ cars, compared with zero cars, by around 10 times. The findings imply that reducing off-street residential car parking requirements can play a significant role in supporting lower car ownership levels among apartment households.

虽然许多研究都探讨了汽车拥有量的决定因素，但对公寓家庭背景下的这些因素知之甚少，因为在公寓家庭中，街边停车位的规定经常是由规划要求规定的，而零汽车家庭则更为明显。本研究基于对澳大利亚三个城市的公寓居民（n = 1316）的调查，旨在了解零汽车和拥有汽车公寓家庭的决定因素。使用二元和多项逻辑回归（包括随机参数建模）分析数据。还开发了汽车拥有量和街外停车位供应的联合模型，以解释这两个变量之间的潜在内生性。结果突显了汽车拥有量与街外停车位供应之间的显着关联，以及一系列社会人口特征、态度、看法、建筑环境和交通特征。研究发现，与零辆汽车相比，平均而言，额外的街边停车位可使拥有 2 辆以上汽车的几率增加约 10 倍。研究结果表明，减少街外住宅停车要求可以在支持降低公寓家庭汽车拥有量方面发挥重要作用。
