Abstract:

Under the dual carbon target， China has implemented a range of preferential policies to facilitate the optimization and upgrading of the new energy vehicle industry chain and supply chain. These measures aim to incentivize manufacturers to augment their investments in low-carbon research and development as well as production， encourage retailers to enhance their efforts in promoting and publicizing low-carbon initiatives， and urge consumers towards embracing green consumption. By leveraging their environmentally friendly characteristics， new energy vehicles are poised to garner consumer favor through the launch of a carbon publicity platform for China's automobile industry chain， thereby facilitating market share expansion and expediting the realization of low-carbon goals in the automotive sector. It focuses on the uncertainty faced by supply chain members when deciding whether to undertake social responsibility and disclose carbon information on a platform， aiming to explore strategies that maximize economic benefits for manufacturers and retailers while enhancing overall social and environmental outcomes. It is revealed that consumers' environmental preferences have a significant impact on the greenness and retail price of new energy vehicles， thereby establishing a symbiotic relationship. Although the manufacturer's profitability is positively correlated with its level of corporate social responsibility （CSR）， it may be adversely affected by the free-rider behavior exhibited by retailers. Therefore， it is imperative for supply chain members to establish a shared objective of collectively constructing a low-carbon supply chain， ensuring equitable profit distribution， enhancing overall societal benefits， and achieving mutual success.
