【大涨解读】无人驾驶板块：L3准入+特斯拉无人测试落地，2026年将进入B端无人车商业模式跑通阶段，商业化拐点催生板块行情

Core Insights - The autonomous driving sector experienced significant gains, with companies like Zhejiang Shibao and Beiqi Blue Valley hitting the upper limit of their stock prices, indicating strong market interest and investor confidence in this industry [1] Event Summary - On December 15, the Ministry of Industry and Information Technology announced the first batch of L3 conditional autonomous driving vehicle permits in China, allowing Changan and Arcfox models to conduct road trials in designated areas of Chongqing and Beijing, marking a shift from testing to commercial application [3] - On the same day, Tesla launched its no-driver Robotaxi testing in Austin, USA, with the Model Y achieving fully autonomous operation, and plans to expand the fleet to 500 vehicles by year-end, currently operating 31 [3] - Multiple cities are accelerating the implementation of smart driving policies, with Beijing, Shenzhen, and Shanghai granting L4 road rights, and the Ministry of Industry and Information Technology expected to release a draft for national standards on L3-L4 by Q4 [3] Institutional Analysis - The approval of L3 vehicles signifies a transition in China's smart driving from "testing and validation" to "compliant mass production and controlled road use," which will accelerate the commercialization process of the industry. The three-pronged management model of "product access + user subject + operational area" provides a clear path for other automakers to follow, with 2026 anticipated as a critical year for L3 mass production [4] - The simultaneous advancement of high-level intelligent driving in China and the US creates a dual catalytic effect. The clear legal responsibilities established by China's L3 approval reduce social risks and regulatory uncertainties, while Tesla's fully autonomous testing validates the feasibility of L4 technology, shifting the industry focus from engineering challenges to commercial viability [4] - By 2026, leading automakers are expected to achieve over 30% growth in revenues related to intelligent driving, benefiting algorithm suppliers and core hardware companies as vehicle production ramps up. Long-term, smart vehicles are projected to reshape the automotive mobility market, establishing a new valuation system based on "intelligent entity revenue capacity = ownership × capability level" [5] - The rollout of L3 technology will create incremental opportunities in the automotive testing and hardware sectors, with increased demand for testing of smart driving vehicle permits. The penetration rates of core components like steer-by-wire and domain controllers are expected to grow rapidly, with the steer-by-wire market projected to increase by over 150% year-on-year by 2026 [5]
