摘要
Formulating tailored emission reduction policies for each Chinese province is crucial due to regional differences in carbon emission evolution patterns.This paper proposes a novel and comprehensive research framework that integrates data envelopment analysis(DEA),Tobit regression,and system dynamics(SD)model to analyze the influence factors and evaluate provincial emission reduction policies while considering regional differences.The DEA method assesses each province’s development resource allocation and carbon emission efficiency.Based on the DEA results,each provinces’key emission influencing factors can be derived combining with Tobit regression and sensitivity analysis of SD.Policies are then selected based on these factors to gauge their effectiveness.SD method is used to simulate carbon emissions under different policy scenarios in the future.The analysis results present obvious differences in resource allocation and regional characteristics among provinces.Qinghai’s emission reduction potential has been preliminarily explored as an example.Energy structure,industry structure,energy intensity,forest coverage,and R&D input intensity are its main influencing factors for carbon emission.The forest carbon sink plays a significant role.The emission reduction of the integrated scenario is not a linear sum of all other scenarios.To ensure the completion of the neutralization goal,further adjustments to the long-term policy and extra measures are needed.
