Green Channel Supply Chain Pricing Decision Considering Blockchain And Product Recycling

Promoting the construction of a green circular economy system is a powerful measure to achieve sustainable development.The production of green products and the recycling of waste products are the foundation for achieving resource recycling.As an important member of society,enterprises should actively participate in green development and invest resources to innovate models for the reuse of waste products.However,in the traditional recycling process,there are still issues of low recycling efficiency and unclear final destination of recycling,which lead to user distrust.Faced with the aforementioned bottlenecks,ensuring the authenticity and sharing of information is extremely important,and blockchain has great potential to alleviate these problems.Blockchain has the characteristics of being tamperproof and leaving traces throughout the entire process,which has attracted widespread attention in multiple fields and scenarios of supply chain.It has strong security and reliability,which helps to improve the management level of enterprises and consumer satisfaction.Based on the above background,considering the impact of blockchain and product recycling on green supply chain decision-making has certain theoretical and practical guiding significance for improving green supply chain management decision-making and enriching blockchain application scenarios.This thesis establishes three green supply chain recycling models,including manufacturer recycling,retailer recycling,and third-party recycling.Considering parameters such as consumer trust weakening factor for green product sources and discount factor for recycling quantity,the pricing decision-making problems of supply chain members are compared and analyzed without and with blockchain technology.Firstly,taking the green supply chain as the background,considering three situations: manufacturer recycling,retailer recycling,and third-party recycling,using Steinberg game to establish a model and find an equilibrium solution,and comparing and analyzing the optimal solutions under different situations.Secondly,considering the manufacturer’s adoption of blockchain technology based on three recycling scenarios,using Steinberg game to establish a model and seek equilibrium solutions,and comparing and analyzing the optimal solutions under different scenarios.Finally,compare the pricing decisions and profit issues of the supply chain under different recovery modes before and after the adoption of blockchain technology,analyze the impact of blockchain technology on the pricing of supply chain members,and based on the results of equilibrium solution,demonstrate the decision-making analysis process in a more intuitive and comprehensive manner through numerical simulation to help supply chain members make optimal choices.The main conclusions of this article are as follows:(1)Without the use of blockchain technology,consumers’ trust in the source of green products is weakened,the discount factor of recycled quantity,and the manufacturer’s green R&D cost coefficient are inversely proportional to the profits of each member of the supply chain;The manufacturer’s profit is always the highest under the retailer’s recycling mode;When the manufacturer’s green R&D cost coefficient is small,the retailer’s profit is the highest under the third-party recovery model;When the manufacturer’s green R&D cost coefficient is large,the retailer’s profit is the highest under the retailer’s recycling mode。(2)In the case of adopting blockchain technology,the sensitivity coefficient of consumers to product traceability levels is proportional to the profits of each member of the supply chain;When the blockchain unit verification cost is small,the manufacturer’s profit is the highest in the retailer’s recovery mode;When the unit verification cost of blockchain is high,the manufacturer’s profit is the highest in the manufacturer’s recovery mode;Which mode of retailer profit is the highest is related to the blockchain unit verification cost and the threshold value of the product traceability level of consumers。(3)Under the manufacturer recycling mode,when using blockchain technology,the retailer’s profit is greater than when not using blockchain technology;When the sensitivity coefficient of consumers to product traceability level is large,the manufacturer’s profit when using blockchain technology is greater than when not using blockchain technology;Under the retailer recycling mode,when the sensitivity coefficient of consumers to the product traceability level is large,the manufacturer’s profit is greater when using blockchain technology than when not using blockchain technology.When the sensitivity coefficient of consumers to the product traceability level is within a certain range,the retailer’s profit is greater when using blockchain technology than when not using blockchain technology.Under the third-party recycling model,when the sensitivity coefficient of consumers to product traceability is large,the manufacturer’s profit when using blockchain technology is greater than when not using blockchain technology;When the sensitivity coefficient of consumers to product traceability level is within a certain range,the profits of retailers and third parties using blockchain technology are greater than those not using blockchain technology.
