Research On Energy Conservation And Emission Reduction System Of Logistics Industry In Guangdong Province From The Perspective Of Low Carbon Economy

In the face of increasing environmental pollution and energy shortage,countries have reached an agreement on the path of sustainable development.As the second largest economy in the world,China’s low-carbon development is of great significance to the global ecological environment.As a sunrise industry in China,the development of logistics industry is accompanied by a large number of energy consumption and carbon emissions.Therefore,the realization of energy conservation and emission reduction of logistics industry is of great significance to China’s low-carbon development.The existing research mainly focuses on the direction of logistics efficiency,lacking the research on energy consumption and pollution emission of logistics industry.Therefore,this paper takes Guangdong Province as an example to study the energy conservation and emission reduction of logistics industry as follows:First of all,through literature research at home and abroad,this paper summarizes the relevant research results,summarizes the influencing factors of carbon emissions of logistics and transportation,and determines the research methods.On this basis,combined with the current situation of the logistics industry in Guangdong Province,this paper analyzes the influencing factors of energy conservation and emission reduction in the logistics industry,determines the carbon emission measurement method and data sources used in this study,and provides theoretical and data support for the subsequent system dynamic model construction.Secondly,the energy conservation and emission reduction system of logistics industry in Guangdong Province is regarded as a dynamic system.According to the system dynamics modeling steps,the system boundary and hypothesis are determined,the system structure chart is constructed,the causality chart is drawn by Vensim-PLE software,and the system flow chart including four subsystems of logistics industry subsystems,economy subsystems,environment subsystems and energy subsystems is drawn,and the data and equations of each variable in the flow chart are determined.Finally,the system dynamic model of energy conservation and emission reduction of logistics industry in Guangdong Province is tested,and the model which is consistent with the actual development is obtained.Based on the theory of scenario analysis,the model is simulated under different scenarios.Through the comparative analysis of the development trend of energy consumption and carbon emission,the influencing factors of energy conservation and emission reduction of logistics industry in Guangdong Province are obtained,and the effective strategies of energy conservation and emission reduction are put forward.The results show that the most effective strategies to realize the development of energy conservation and emission reduction of logistics industry are to reduce the unit energy consumption and emission coefficient of logistics transportation vehicles in Guangdong Province,among which the strategies to reduce the unit energy consumption and carbon emission coefficient of gasoline vehicles and diesel vehicles are the best;adjusting the structure of logistics transportation,reducing the proportion of highways transportation and increasing the proportion of railways transportation are the effective strategies to realize the development of energy conservation and emission reduction of logistics industry;improving the level of environmental protection investment is an effective strategy to achieve carbon emission reduction in the logistics industry;at the same time,the energy conservation and emission reduction effect of the combination of the above strategies is better than that of the same degree of single strategy.Therefore,in the actual development of logistics industry in Guangdong Province,a variety of energy conservation and emission reduction strategies should be used at the same time.
