Analysis on the Logistics Policy Impact of Energy Saving and Emission Reduction: A System Dynamics Approach

摘要

To advocate green logistics and circular economy, the logistics policy simulation model of energy saving and emission reduction based on system dynamics (SD) was constructed. Within this context, the nitrogen oxide (NOx) emissions were regarded as the object of this study and the policy simulation was implemented in four ways. The results of the SD model have demonstrated that increasing the added value of the tertiary industry can significantly reduce NOx emissions. The effect of energy saving and emission reduction via reduction of the highway freight turnover is obvious. However, the emission decline effect of improving the proportion of gas energy consumption is not manifest compared to the optimization of transportation structure. In addition, increasing investment in environmental protection can only serve as an auxiliary approach. Therefore, the structural policies are crucial.
