The Decision Of Low-carbon Supply Chain Under The Background Of Dual-channel

With the worsening of climate and environment,the problem of low carbon emission reduction has been concerned by many countries.China has formulated a series of emission reduction targets and policies,and enterprises are also facing the pressure of emission reduction.The key problems of low carbon supply chain are as follows: One is to achieve the dual goal of not reducing the income of enterprises while improving the level of emission reduction;The other is to reduce the price of low-carbon products and expand the market demand of low-carbon products.The research on the optimization and operation of low-carbon supply chain is mainly focused on these two problems,but there are still some obstacles to the development of low-carbon supply chain.The development of electronic commerce brings a new development opportunity for low-carbon emission reduction enterprises and provides a new direction for solving the key problems of low-carbon supply chain.Under the background of dual channels,whether the low-carbon supply chain can use different channels to achieve the improvement of emission reduction level and the income of supply chain members is a key issue that deserves to be studied.Therefore,this paper studies the decision-making of low-carbon supply chain under the background of two channels.A supply chain demand model with a single low-carbon product and the product competition is established under the background of dual channels.And based on Steinberg's master-slave game model,this paper studies the decision-making of secondary supply emission reduction followed by manufacturers and retailers.First the different channel selection for manufacturers and the cooperative compensation strategy for retailers are studied in the case of manufacturer producing a single low-carbon product,and the effects of different manufacturer strategies on emission reduction level and supply chain members are analyzed.Then,the problem of channel selection for manufacturers in the presence of product competition is also studied,and comparing the effects of various selection strategies on supply chain members and emission reduction levels.Finally,examples are designed separately to quantitatively analyze the effects of low carbon preference,channel preference,product initial preference ratio and product competition degree on emission reduction level,decision-making and profit of supply chain members.The correctness and validity of the propositional conclusions are verified.Through model calculation and example analysis,the following conclusions are obtained: emission-reducing manufacturers opening online direct marketing channels are always beneficial to emission reduction levels and manufacturers' earnings,and the price of low-carbon products is lower than that of traditional retail channels;When the manufacturers open direct marketing channels,this causes the loss to retailers as a result of partition of off-line market demand,so they need to consider revenue-sharing strategies to compensate retailers to encourage retailers;Compared with traditional retail channels,when manufacturers open online direct selling channels,the Pareto efficiency of emission reduction levels,manufacturers' profits and retailers' profits can be improved by means of the revenue-sharing strategy.The low carbon preference of consumers and the degree of product competition are beneficial to the level of emission reduction,manufacturers and retailers;when there is product competition,the effect of product initial preference ratio on emission reduction level and the profit of supply chain members is restricted by consumer channel preference.
