网络零售供应链对城市物流空间重构及其环境效应研究

The bloom in e-tailing and logistics supply chain is the focal point both in global socioeconomic development and academic research. Nevertheless, less is known about the spatial coupling logic and environmental impacts of e-tailing and supply chain activities. By intensive geographical analyses and urban studies, this project aims to fill this gap to examine how the e-tailing-driven supply chain strategies spatially and environmentally reorganize urban logistics spaces. The city of Shenzhen is taken as the primary study case. New open-source data sets, including POI data, are incorporated to support conventional official survey data as the data basement of this study. Meanwhile, qualitative methods (in-depth interview and case study), geographic visualization, quantitative econometric models and scenario simulation approaches are mixed here to meet different research objectives and requirements. Regarding the effects at the region-city level, one empirical study aims to investigate the e-tailing-catalyzed logistics sprawl and its environmental impacts at the metropolitan level. Another empirical study focuses on measuring the space-time accessibility changes and external costs of last-mile delivery depots at the urban-neighborhood scale. The logistics land demands are to be forecasted to adapt the rise of e-tailing supply chain. In addition, this study attempts to build a supply chain-based simulation models for city logistics policies. The implications of this project firstly lies in establishing a theory framework which integrates e-tailng, supply chain activities, space-environment effects at the city level. The proposed supply-chain based also is going to be further applied in urban space studies. Both the theoretical and methodological progress will promote the development of the geography of logistics and distribution, and facilitate shaping sustainable city logistics policy framework.

网络零售与物流供应链的快速发展已成为社会经济发展及科学研究热点。但是，有关网络零售和供应链空间耦合机制及其环境响应的研究还有待深入。基于地理学与城市研究视角，本项目主要以深圳为案例，采集开源地图POI数据、建筑及商事普查数据等，灵活运用案例、访谈、地理可视化、计量经济以及情景模拟等混合研究方法，从过程机理与空间环境效应等维度，考察“网络零售如何通过供应链活动的空间组织驱动城市物流空间重构”。在区域-城市面，拟采用多城市比较的方法，探究“网络零售驱动下的城市物流蔓延及其能源排放特征变化”；在城市-社区面，分析“末端配送网络时空可达性及其环境成本”。本研究将建立网络零售和供应链空间耦合分析框架，将供应链分析法拓展到城市空间领域，促进物流地理学的发展，帮助城市物流克服空间困境、环境困境和治理困境。
