摘　　要：本文利用夜间灯光数据测算城市空间紧凑度,并匹配2018年中国家庭收入调查数据,实证考察了城市空间形态对城市家庭消费储蓄的影响。研究显示,城市空间形态不紧凑对家庭储蓄率存在负向影响,且上述影响在经济活动中心数更多、规模更大城市以及相对贫困、职住距离更远的家庭中更加显著。机制分析表明,城市空间形态对家庭收入不存在显著影响,但是不紧凑的城市空间形态通过推动居民通勤成本上升,进而提高家庭交通和服务消费支出,降低了家庭储蓄率。此外,不紧凑空间形态城市较低的家庭储蓄率和交通便利性,会扭曲个体的消费储蓄路径,居民自身福利的主观感知变差,由此构成了城市不紧凑发展的隐性损害,而完善良好的城市交通设施能够有效减弱上述损害影响。This article uses nighttime light data to measure urban spatial compactness and matches CHIP2018 data to empirically ex-amine the impact of urban spatial shape on household consumption and savings.Research has shown that the lack of compact urban spatial shape has a negative impact on household savings rates,and this impact is more pronounced in cities with more economic ac-tivity centers and larger scales,as well as in households with relative poverty and farther work and housing distances.Mechanism analysis shows that urban spatial shape does not have a significant impact on household income,but a less compact urban spatial shape drives up commuting costs for residents,thereby increasing household transportation and service consumption expenditures and reducing household savings rates.In addition,the lower household savings rate and transportation convenience in cities with less compact spatial shape can distort individual consumption and savings paths,leading to a decrease in the subjective perception of res-idents'own welfare.This constitutes implicit damage to the development of less compact cities,and a well-developed urban transpor-tation infrastructure can effectively mitigate the implicit damage.
