The technology sector experienced a significant decline today (December 15). Major market indices fluctuated downward, with the Shanghai Composite Index dropping 0.55%, the Shenzhen Component Index falling 1.1%, and the ChiNext Index plunging 1.77%. Among core market indices, dividend-focused indices performed relatively well, with the SSE Dividend Index and CSI Dividend Index rising 0.75% and 0.56%, respectively.
Sector-wise, dairy, insurance, and aircraft manufacturing concepts led gains, with their indices rising over 2%. Satellite internet, shipping, and aquaculture concepts also performed well. However, the technology sector suffered heavy losses, with optical modules, memory chips, and server concepts among the worst performers. Over 8 billion yuan in net capital outflow was recorded from the semiconductor sector.
**CHINA MOBILE Releases 6G Transmission Technology White Paper and Prototype** At the "Computing Network Foundation, Universal Intelligence Interconnection – 6G-Oriented Computing Power Network Innovation Technology Forum" during the 2025 China Information and Communication Conference, CHINA MOBILE officially unveiled its "6G Transmission Technology White Paper" and "6G Transmission System Prototype 1.0."
The white paper systematically outlines CHINA MOBILE's vision, architectural design, and key technological directions for 6G transmission networks. The prototype serves as the core implementation of these concepts, successfully demonstrating three critical capabilities: intelligent connectivity driven by service awareness, distributed dynamic channel control for high-mobility scenarios, and multi-dimensional channel collaborative transmission. This marks a significant step from theoretical research to system validation in 6G transmission technology.
**China Accelerates 6G Development** China has conducted four consecutive years of 6G technology trials. At the recent 2025 6G Development Conference, the country announced the successful completion of Phase 1 trials, accumulating over 300 key technological achievements. The global 6G industry is currently in the late stages of standardization and technical testing, with market size expected to grow rapidly. According to the China Academy of Information and Communications Technology, China's 6G market could reach 1.3 trillion yuan by 2030, becoming the world's largest.
National and local policies are synergizing to support 6G development. The 2025 government work report explicitly calls for cultivating future industries like 6G, with Beijing, Shandong, and Shanghai introducing supportive policies covering R&D, standardization, industrial ecosystems, and application scenarios.
**High R&D Investment in 6G Concept Stocks** Among 34 A-share 6G concept stocks, eight have R&D expenses exceeding 10% of revenue in the first three quarters. Leading companies include ZRTEK Technology (32.12%), Zhenyou Technology (23.81%), and Hi-Target (21.85%). ZRTEK Technology reported a 65.76% revenue increase and 598.09% net profit growth, attributing this to its position as a core chip supplier for 6G satellite internet.
Since the second half of the year, 6G concept stocks have attracted significant institutional attention, with 12 companies receiving research visits from over 10 institutions. Quectel Wireless Solutions, Tongyu Communication, and Kinwong Electronic led with 267, 191, and 98 institutional visits, respectively. Quectel emphasized its active participation in 6G-related standardization and patent development through 3GPP.
