On December 16th, with the mid-December deadline for the expiration of the new energy vehicle purchase tax exemption policy looming large and just half a month to go, the scrappage and trade-in subsidy (commonly known as the national subsidy) is also undergoing a phase of transition and refinement between the old and new policy frameworks. Recently, a reporter's exploration of the frontline auto market unveiled that the anticipated 'last-train effect' of the policy, which typically spurs a flurry of purchases before expiration, failed to materialize as expected. Rather than witnessing a buying frenzy, the market's response underscored the challenges of adaptation and the rational decision-making processes at play amidst policy shifts, following a prolonged period of policy-driven market dynamics. Presently, a pervasive sense of anticipation and caution pervades the auto market, with consumers holding their breath for the unveiling of the optimized 'national subsidy' policy in the coming year. Sales representatives from multiple automotive brands shared that they had initially anticipated a surge in car-buying activity in December. However, the reality paints a different picture, with the December auto market mirroring the tranquility of November, showing no signs of a year-end purchasing spike fueled by the purchase tax policy.
