Study On Efficiency And Equity Of Cross-regional Green Supply Chain Coordination With Carbon Emissions Trading And Multiple Governments’ Intervention

With the rapid development of global economy,the emissions of greenhouse gases increase a lot,which makes the ecological environment get worse than before.In order to control greenhouse gas emissions,mitigate climate change and ensure that social resource consumption and environmental negative effect are minimum,the Chinese government would promise energy consumption per GDP compared to 2005 decreased 40%-45%in 2020.On the purpose of the carbon emission reduction,green supply chain has become a hot topic which supply chain managers have paid more attention to.However,as upstream and downstream firms in the supply chain are often located in different regions,how to consider the different local governments different regional cross-regional control strategy,study carbon emissions trading on emission reduction efficiency and interregional equity.Based on the previous researches,this paper studies the efficiency and fairness of cross-regional green supply chain coordination on the basis of carbon emission trading,which take.The main contents are as follows:(1)Research on cross-regional green supply chain coordination with enterprises’ autonomous reduction.Based on Stackelberg game,this paper analyzes the effects of product price and unit carbon emission reduction rate on the decisions of upstream and downstream supply chain enterprises.And the results show that the elasticity coefficients of product price and carbon emission reduction per unit have an obvious effect on the profits of supply chain enterprises.In addition,when the supply chain enterprises cooperate together,the profits and carbon emission reduction per unit of product are better than decentralized supply chain.(2)Research on cross-regional green supply chain coordination with carbon emission permit restriction.Based on Stackelberg game theory,this paper analyzes the effect of carbon price and unit price of carbon emissions of carbon production and non-autonomous carbon emission reduction in upstream and downstream supply chain enterprises.Based on the comparative analysis,the results show that the elasticity coefficients of product price and carbon emission reduction per unit product,the price of carbon trading jointly formulated by the government,and the government punishment factor are the two factors that influence the coordination of green supply chain in the decentralized and centralized enterprises.Supply chain enterprises have obvious effect,and the centralized strategy of corporate earnings and unit products,government penalties on carbon emissions have a significant impact,and when the supply chain enterprises are in the full cooperation,the supply chain profits and unit of carbon emissions are better than decentralized supply chain.(3)Study on equity of cross-regional green supply chain coordination with multiple governments’ intervention,carbon emission permit restriction and carbon emissions trading.In view of the limitation of carbon emission right and the existence of inter-enterprise carbon emissions trading,considering the fairness of different local governments’differentiated control strategies in cross-regional green supply chain,aiming at minimizing the unfairness of CO2 emission entitlements.The effect of carbon price,carbon trading price and carbon emission quota on the decision of production and non-self-carbon emission reduction of upstream and downstream enterprises in the supply chain.Based on Stackelberg game and bi-level programming model,a centralized cross-regional green supply chain coordination model was built.Through comparative analysis,the conclusion shows that the product price elasticity coefficient,unit product carbon emission reduction elasticity coefficient,government joint development of carbon trading price,carbon emission quota on supply chain enterprise income and fairness between enterprises has obvious effect.
