The influence of carbon emission reduction instruments on blockchain technology adoption in recycling batteries of the new energy vehicles.docx

The key findings are as follows. Under a carbon tax system, (1) carbon emission reduction encourages the battery supplier to adopt blockchain technology; (2) blockchain technology adoption increases the profits of NEV supply chain stakeholders. Under carbon cap-and-trade regulations, (1) the unit outsourcing fee and the performance of the blockchain technology impact the investment decision of the manufacturer; (2) the profit of the third-party enterprise is increased by introducing the blockchain technology. Under both policies, improving the efficiency of blockchain technology helps to upgrade the traceability level and contribute to carbon neutrality in the NEV supply chain.
