摘　　要：低碳经济环境下,中小型制造商为了缓解碳减排资金压力,选择依托电商平台进行线上销售。基于由电商平台主导的低碳电商供应链系统,本文将产品的网络外部性纳入模型,构建了碳交易政策和碳税政策下的供应链决策模型,研究政府和低碳电商供应链“共赢”的最佳碳政策。研究发现:(1)探讨各成员企业的最佳碳政策时,制造商的实际碳排放量与政府碳配额的大小关系是重要的影响因素。当实际碳排放量超过政府规定的碳配额时,若碳交易价格超过一个特定的阈值,碳交易政策的惩罚力度大于碳税政策,此时对于供应链成员和政府而言,实施碳税政策更有利;若碳交易价格小于该阈值,则反之。当实际碳排放量小于政府规定的碳配额时,对供应链成员和政府而言,碳交易政策是最佳碳政策。(2)产品的网络外部性对产品价格、市场需求和供应链成员的利润都有正向作用。这些结论为电商供应链成员在低碳背景下的决策提供了参考。In the low-carbon economic environment,small and medium-sized manufacturers( SMM) lack economic strength,have great pressure to achieve carbon emission reduction and low-carbon transformation.To alleviate financial pressure and increase profit margins,SMM choose to rely on e-commerce platforms for online sales.At this time,they do not need to spend more on advertising,logistics and after-sales service,etc.In addition,the e-commerce platform has the characteristics of significant network externalities,so that SMM can quickly expand the consumer market and obtain more profit.Meanwhile,promoting the low-carbon transformation of SMM is also the focus of the government′s work.A favorable policy environment can help to promote the sustainable development of SMM.Carbon trading policy and carbon tax policy are common carbon policies,which have been implemented in many countries.So for SMM relying on e-commerce platforms for sales,which carbon policy is more effective,carbon trading policy or carbon tax policy?Enterprises and governments must clarify this issue,which is of great significance to the sustainable development of society and the stable operation of supply chain enterprises.Based on this,this paper considers a low-carbon e-commerce supply chain( LCE-SC) system dominated by an e-commerce platform and subordinated by a manufacturer,incorporates the network externality characteristics of products into the model to explore the “win-win situation” for the government and the LCE-SC optimal carbon policy.Firstly,we describe the model and make a series of reasonable assumptions,build a supply chain decision model under the carbon tax and carbon trading policies,and use the backward induction method to calculate the optimal solutions.Through analysis,we find that changes in carbon tax rates and carbon transaction prices can affect optimal product prices,market demand,and members′ profits,but do not affect the service level of the e-commerce platform.Additionally,the impact of carbon trading price on product pric
