基于生命周期的电商物流碳排放系统动力学模型研究

Research on System Dynamics Model of E-commerce Logistics Carbon Emission Based on the Life Cycle

随着科技的进步和电子商务的蓬勃发展,网络购物背后一系列物流环节所涉及的能源消耗与温室气体的产生正在对环境造成越来越大的破坏。文中针对电商物流整个生命周期全过程构建电商物流碳排放系统动力学模型,并以京东商城手机产品线上销售为实例进行测算与模拟分析。结果表明:运输和包装两个环节是电商物流系统节能减排的重点所在,电商物流在降低运输能耗、提高可循环包装的使用比例以及减少退换货率方面具备实现碳减排的潜力。

With the advancement of technology and booming e-commerce, the energy consumption and the generation of greenhouse gases involved in a series of logistics links behind online shopping are causing damage to the environment.This paper builds a system dynamics model of e-commerce logistics carbon emissions based on the whole life cycle of e-commerce logistics, and takes the online sales of mobile phone products in Jingdong Mall as an example for measurement and simulation analysis.The results show that transportation and packaging links are the key points of energy saving and emission reduction in e-commerce logistics system.E-commerce logistics has the potential to reduce carbon emissions in terms of lowering transport energy consumption, increasing the proportion of recyclable packaging and reducing the rate of return and exchange.
