摘要

本文分析了网络零售对具有上游供应商的空间双寡头垄断的运输气体排放的影响。我们考虑:(1)与两家实体零售商的纯线下竞争;(2)线上/线下竞争，即线上零售商与线下零售商的竞争。当上游供应商位于城市中心时，线上/线下竞争下的交通气体排放更低。然而，当上游供应商处于终端时，在线零售可能会增加运输气体排放。这种情况发生在:(1)在线上/线下竞争情况下，实体零售商不位于端点;(2)供应商的商用车运输成本明显大于消费者的私家车运输成本;(3)线下零售商的竞争力足够高。

Transportation gas emissions with online retailing: a spatial model

ABSTRACT We analyse the impact of online retailing on transportation gas emissions in a spatial duopoly with upstream suppliers. We consider: (1) pure offline competition with two physical retailers; and (2) online/offline competition, where an online retailer competes against an offline retailer. When the upstream suppliers are located in the city centre, transportation gas emissions are lower under online/offline competition. However, when the upstream suppliers are at the endpoints, online retailing might increase transportation gas emissions. This happens when: (1) in the online/offline competition case, the physical retailer does not locate at the endpoint; (2) the transportation costs of the suppliers’ commercial trucks are sufficiently larger than those of the consumers’ private cars; and (3) the competitiveness of the offline retailer is high enough.

期刊介绍： Spatial Economic Analysis is a pioneering economics journal dedicated to the development of theory and methods in spatial economics, published by two of the world"s leading learned societies in the analysis of spatial economics, the Regional Studies Association and the British and Irish Section of the Regional Science Association International. A spatial perspective has become increasingly relevant to our understanding of economic phenomena, both on the global scale and at the scale of cities and regions. The growth in international trade, the opening up of emerging markets, the restructuring of the world economy along regional lines, and overall strategic and political significance of globalization, have re-emphasised the importance of geographical analysis.
