Research on Remanufacturing Reverse Supply Chain Optimization Strategies Driven by Enhanced Carbon Reduction Capability

Abstract

The reverse supply chain is a key driver of the circular economy, and its low-carbon operation plays a vital role in achieving the “Dual Carbon” goals. To address this issue, this study takes the remanufacturing rate ( ) as a core variable, constructs a two-tier remanufacturing reverse supply chain system dynamics model. The model analyzes the impact mechanism of  on the carbon emissions of supply chain members. By enhancing carbon emission reduction capability, it investigates the phased characteristics of carbon reduction investment strategies to optimize the low-carbon operation of the reverse supply chain. Built on the Vensim platform, the model with carbon emission features from processes including treatment, disassembly, retreatment, and remanufacturing. Simulation results reveal that collector' carbon emissions decline as  grows, while remanufacturer' emissions peak at moderate  levels. When carbon reduction investments are introduced, the optimal strategies of the collector and the remanufacturer present phased characteristics with distinct critical thresholds. The study offers theoretical and quantitative support for corporate carbon reduction decisions and differentiated policy-making in reverse supply chains.
