Research On The Impact Of Emission Reduction Technology Investment On Supply Chain Cooperation Strategies Under Consumer Low-carbon Preferences

Currently,establishing a green,low-carbon,and sustainable supply chain system has become an important task facing the world.In response to the call for low-carbon emission reduction,many enterprises have begun to invest in research and development of emission reduction technologies and have attempted to cooperate among enterprises.This thesis establishes a three-level supply chain consisting of suppliers,manufacturers,and retailers.Under consumer low-carbon preferences,this thesis studies decision-making strategies under four R&D investment modes: supplier independent R&D,manufacturer independent R&D,supplier+manufacturer vertical cooperative R&D,and manufacturer+retailer vertical cooperative R&D.Under the two vertical cooperative R&D modes,revenue sharing contracts are introduced,and a Stackelberg game model is established to analyze the optimal decision-making of the supply chain.This article draws the following conclusions:(1)Under the four modes,the higher the corporate unit profit,the more investment in research and development of emission reduction technologies;The higher the consumer’s low-carbon preference,the more enterprises invest in research and development of emission reduction technologies.This indicates that supply chain enterprises’ investment in research and development of emission reduction technologies for products is effective.(2)Under the supplier independent research and development model,the higher the consumer’s low-carbon preference,the higher the profits of each enterprise in the supply chain;Under the independent research and development model of manufacturers,the higher the consumer’s low-carbon preference,the higher the profits of manufacturers and retailers,and the profits of suppliers first increase and then decrease.Under the vertical cooperative R&D model of supplier+manufacturer,the higher the consumer’s low-carbon preference,the higher the profits of each enterprise in the supply chain;Under the vertical cooperative R&D model of manufacturer+retailer,the higher the consumer’s low-carbon preference,the higher the profits of each enterprise.(3)In a manufacturer led supply chain,suppliers cannot independently bear the cost of R&D investment in emission reduction technologies.(4)When manufacturers conduct independent research and development,the enthusiasm of enterprises for reducing emissions is higher than that of suppliers,which is conducive to the long-term development of low-carbon supply chains;In vertical collaborative research and development between suppliers and manufacturers,enterprises are more proactive in reducing emissions than manufacturers and retailers,which is conducive to the long-term development of low-carbon supply chains.(5)In all R&D modes,there is a "free rider" behavior in the supply chain,but the "free rider" behavior in the vertical cooperative R&D mode is weaker than that in the independent R&D mode.(6)Under the four decision-making modes,the supplier+manufacturer vertical cooperative R&D strategy is the optimal decision,while the supplier independent R&D strategy is the most uncoordinated decision.That is,in a manufacturer led supply chain,suppliers,as the upstream supply chain that provides raw materials,have limited emission reduction,which can lead to a negative state of operation between supply chains,at which time the profits of the supply chain will decline.(7)At 0.5002＜δ＜0.7502,the profits of all enterprises in the supply chain under the supplier+manufacturer vertical cooperative R&D model were greater than those under the supplier independent R&D model,the manufacturer independent R&D model,and the manufacturer+retailer vertical cooperative R&D model.Under the vertical cooperative research and development model,Pareto was better at 0.5002＜δ＜0.7502.At this time,the profits of suppliers and manufacturers are the largest.This thesis takes the low-carbon supply chain as the background,analyzes the impact of enterprise emission reduction R&D investment on enterprise performance under consumer low-carbon preferences,provides a new perspective for the study of low-carbon supply chain,and explores how the optimal decision-making of enterprises changes under different cooperation methods.The model construction conforms to the supply chain operation under the background of changing consumption concepts,which has certain theoretical and practical significance.
