| As the low carbon idea is promoted effectively,the consumer idea has been transformed,and consumers choose more and more commodities with a high degree of low-carbon when they buy commodities.To cope with the fast growing low carbon demand,manufacturers often make additional emission reduction investment on the basis of fulfilling their own emission reduction tasks to meet the low carbon demand of consumers.Today,as telecommunication and Internet techniques develop rapidly,information exchange and technology sharing among enterprises are becoming more frequent.Increase the amount of carbon dioxide emitted by the companies after they have invested,there is always the risk that other enterprises will obtain the results for free through imitation,learning and other means And companies find it hard to get all the benefits from investing in reducing emissions.At this time,in order to pursue the maximization of benefits,enterprises will often use the spillover loss of market rights transfer technology.So,the thesis integrates the technological spillover and the market forces into the SCM,and explores the influence mechanism of technology spillover and market power structure on manufacturers’ additional emission reduction investment decisions at different low carbon levels by analyzing the optimal investment decisions of manufacturers under different power structures.The study found:Firstly,this paper analyzes the optimal decision of additional emission reduction investment of manufacturers with different emission reduction levels under three market structures.It is found that under these 3 kinds of rights,when technological spillover is below a given value,the optimal decision of additional emission reduction investment in the supply chain is that the manufacturer with high emission reduction level makes additional emission reduction investment alone.When technological spillover exceeds a given value,the optimal decision of additional emission reduction investment in the supply chain is that the manufacturer with low emission reduction level makes additional emission reduction investment decision independently;When the technological spillover is in a given scope,the optimal decision of additional emission reduction investment in the supply chain is that both manufacturers make additional emission reduction investment at the same time.Second,in the context of various market forces,this paper calculates the optimal investment decision of manufacturers for additional emission reduction,and the influence of technology spillover and low carbon preference on additional emission reduction investment decision.The results show that technology spillover does not always have a negative effect on enterprises’ additional emission reduction investment under different market power structures.(1)In a market-force architecture dominated by suppliers,when manufacturers with low emission reduction level independently add emission reduction investment,when market demand and low carbon preference meet certain conditions,The degree of emission reduction will be firstly raised and then reduced as the technological spillover ratio is raised.(2)In a market-driven market force structure dominated by manufacturers,when the manufacturers with low emission reduction level separately make additional emission reduction investment,when the market demand and low carbon preference reach a certain critical point,the manufacturers with low emission reduction level will make additional emission reduction investment at the maximum level;Otherwise,low emission reduction manufacturers will reduce their level of additional emission reduction investment.(3)In a vertical Nash Power Structure,when both firms are simultaneously investing in reducing their emissions,the emission reduction investment level of manufacturers with low emission reduction level is first positively correlated with technology spillover,and gradually becomes negative correlation with the increase of spillover rate.Finally,Comparative analysis is made on the extra investment in reducing emissions,production and profitability of firms in various market forces.The results show that under the manufacturer-dominated power structure,the optimal decision of supply chain is to make additional emission reduction investment for manufacturers with high emission reduction level.In a power structure that is dominated by suppliers,it is the best choice to invest more in reducing emissions for those who have a lower emission.Under the vertical Nash structure,the optimal decision of supply chain is for both manufacturers to make additional emission reduction investments at the same time.If the technology spillover rate is high,the additional emission reduction investment and output level of manufacturers with high emission reduction level are the largest under the manufacturer-dominated market power structure.If the technology spillover rate is low,the amount of additional emission reduction investment and output level of manufacturers with low emission reduction level are the largest under the vertical Nashi structure. |
