Research On Operation Strategy Of Green Supply Chain Under The Background Of Blockchain Technology

Under the goal of carbon peaking and carbon neutrality,green supply chain management has become an inevitable trend,but the information asymmetry generated in the process of practice has hindered the cooperation efficiency between upstream and downstream enterprises,and caused problems such as consumers’ low trust in product information.The implementation of blockchain technology in the green supply chain has brought new ideas and opportunities to solve the above-mentioned problems,thanks to its advantages of decentralization,information tampering resistance,and anti-counterfeiting traceability.However,there is still a lack of research on the impact mechanism of the integration of blockchain technology and the "dual chain" of the green supply chain.Firstly,how to improve the efficiency of green supply chain and encourage enterprises to carry out green production with the help of blockchain technology has become a matter of great importance to the government;secondly,enterprises need to think how to implement technological innovation strategy with the help of benign competition opportunities formed by external competition;thirdly,the introduction of blockchain technology will bring additional cost input to the green supply chain,which has caused financial constraints for most enterprises.Therefore,this paper discusses and promotes the "dual chain" integration of blockchain technology and green supply chain from the perspective of government policy support,external competitors and their own strength.This paper takes the green supply chain under the background of blockchain technology as the research object,and introduces the key factors that affect the operation decision of the green supply chain.Firstly,from the perspective of government subsidies,a multi-stage dynamic game model of green supply chain under different government subsidy strategies is constructed,and the theoretical and numerical analysis of the impact of government subsidies on green supply chain operation strategies is conducted.Secondly,starting from the external competition faced by enterprises,the competition between enterprises is introduced into the construction of green supply chain models,nest the theoretical framework of Stackelberg game and Nash game,compare the profits of supply chain members under the different competition models horizontally and vertically,and analyze the impact of external competition on the operation decision of green supply chain.Finally,starting from the enterprise’s own capabilities,consider the realistic factors of capital constraints caused by blockchain technology investment,study and compare the optimal operation decisions and profits of enterprises under the four strategies of non-financing,trade credit financing,bank credit financing and mixed financing,and explore the optimal financing strategies adopted by capital-constrained entities under different influencing factors.Through research,it is found that enterprise investment and application of blockchain technology need to measure the unit application cost of blockchain technology and strive to improve the investment efficiency of blockchain technology;Government subsidies in the context of blockchain technology can not only stimulate technological innovation of green supply chain enterprises,but also improve the overall social welfare;External competition generally drives enterprises to invest in blockchain technology,but the dividends brought by technology will decrease with the increase of competition intensity;There is no unique optimal financing strategy for enterprises with capital constraints.It is necessary to comprehensively consider the impact of various factors and adjust its financing strategy according to the development stage of blockchain technology.
