On December 8, the Passenger Car Association stated that the hollowing trend of profits in the automotive industry is very severe, with significant profit diversion from upstream. Various regions are vigorously promoting the implementation of the "two new" policies, effectively releasing the vitality of domestic demand. The effects of the policy for replacing old consumer goods with new ones are notably expanding, but the improvement in the automotive industry's profitability is significantly lagging behind that of other consumer goods. As the national effort to combat "involution" continues, the automotive industry's profits are shrinking due to the fact that the profit margins in the non-ferrous metal mining and selection industry exceed 30%, the upstream steel industry's profits have significantly improved, the battery industry is highly profitable, and the high costs associated with smart driving.
