New Energy Vehicles' Technological Innovation Strategy Under Dual Credit Policy: The Role of Blockchain Adoption and Demand Information Sharing

This paper explores the impact of market uncertainty and risk attitudes on technological innovation in new energy vehicles (NEVs) under the dual credit policy, focusing on the roles of manufacturers' demand information sharing and blockchain adoption. We develop game-theoretic models based on mean-variance theory to derive optimal strategies across four scenarios. Our analysis reveals that the dual credit policy can effectively incentivize NEV technological innovation, with the incentive effect becoming more pronounced as the technological innovation credit coefficient or credit price increases. However, manufacturers' demand information sharing does not always amplify the positive impact of the dual credit policy on technological innovation; under certain conditions, it may even diminish the level of innovation. This effect is contingent upon consumer demand uncertainty and the risk sensitivity of supply chain members. Moreover, the adoption of blockchain technology is subject to a cost threshold, which can be raised by the dual credit policy. As the technological innovation credit coefficient or credit price rises, the conditions for blockchain adoption decreases, thereby facilitating the digital transformation of the NEV industry.
