城市空间形态如何影响居民消费

The Effect of the Urban Geometric Shape on Household Consumption

什么样的城市空间形态更有利于居民消费?在扩大内需战略和新型城镇化战略衔接推进的背景下,本文匹配全球城市边界(CUB)数据集与中国家庭追踪调查(CFPS)数据,分析了以紧凑程度和几何形态为表征的城市空间形态对居民消费的影响及作用机制。研究发现,松散化的城市空间形态会对居民消费的扩容升级产生显著的负向影响。从影响机制来看,城市空间形态越松散,居民家庭社会网络密切度则越低,居民消费动力不足,同时不利于激励消费品供给多样性,阻碍居民消费规模的扩大。进一步分析发现,推动优化交通网络设施以及促进消费场景的数字化渗透能够在一定程度上缓解松散城市形态对居民消费的抑制效应。本文研究发现对于如何推进城市空间的紧凑合理布局,改善消费条件、创新消费场景,从而激发居民消费潜能具有重要启示和参考价值。

What kind of urban geometric shape is more conducive to residents'consumption?In the context of the articulated promotion of the strategy of expanding domestic demand and the strategy of new urbanization,we matched the Global Urban Boundary(GUB)dataset with the data of China Family Panel Studies(CFPS)to analyze the impact of urban geometric shape characterized by compactness and geometry on household consumption and its working mechanism.It is found that loose urban geometry has a significant negative impact on the expansion and upgrading of household consumption.From the perspective of the impact mechanism,the looser the urban geometry,the less close the social network of households,which weakens the consumption motive of residents,and is not conducive to stimulating the diversity of consumer goods supply and is thus hindering the expansion of household consumption.Further analysis reveals that the improved transportation network and facilities and the digital penetration of consumption scenarios are conducive to alleviating the inhibitory effect of loose urban morphology on household consumption.Compared to previous research,this paper has the following possible marginal contributions.First,this paper incorporates the characteristics of urban spatial externalities into the research framework of household consumption in China,analyzes the heterogeneity of households'economic decision-making from the unique perspective of urban geometry,verifies its influence on residents'consumption behavior,and enriches the theoretical research on the unbalanced and inadequate development of household consumption in China.Additionally,from the perspective of supply and demand fundamentals,this paper analyzes how urban morphological characteristics affects China's household consumption,and discusses the feasible path to alleviate the pressure of sluggish domestic demand in cities under the disadvantage of spatial form,so as to provide an empirical reference for China to further expand domestic demand,promote consumption upgrading and build consumption-hub cities.From the perspective of policy significance,the research findings of this paper have important enlightenment and reference value for how to promote the compact and rational layout of urban space,improve consumption conditions,and create new consumption scenarios,so as to boost consumption.Future research may consider delving into the impact of urban geometric shape on the consumption of new businesses in the digital age.
