过去很长一段时间，市场提到国产芯片的第一反应往往是"卡 脖子"或者"不好用"。但经过产业链上下游多年的追赶，情况 正在发生改变：2025年的国产芯片行业已呈现出一番新气 象。 作者：郑晨烨 封图：图虫创意 11月22日，在西宁一场高校电竞比赛现场，一台外观低调的台式电脑正在运行高负载的大型电脑 游戏《黑神话：悟空》。 这台机器并未搭载英特尔或AMD（超威半导体）的处理器，但实时画面帧率（指每秒钟连续显示 的图像的数量）却维持在极高水平。"在测试中，《无畏契约》的帧率接近200帧，《黑神话：悟 空》的帧率接近300帧。"青岛雷神科技股份有限公司（下称"雷神科技"）台式机产品总监丁国彦 在接受经济观察报采访时分享了这两个大型电脑游戏的实测数据，并指出上述设备搭载的是国产海 光C86处理器。 这个数据具有标志性意义。对主流大型竞技游戏而言，60帧通常被视为画面流畅的"及格线"。超 过144帧乃至达到200帧，意味着硬件性能已能够满足职业电竞场景下对毫秒级响应速度的严苛需 求。 类似的突破在2025年还有很多。在汽车制造端，11月19日下线的广汽昊铂GT"攀登版"，其智能 座舱与音频处理完全由瑞芯微（603893.S ...

据证券时报·数据宝统计，3家及以上机构评级且前三季度净利润同比翻倍增长、扣非平均净资产收益率 超5%的个股中，有33只机构一致预测明后两年净利润增速均超20%，且最新价较年内高点回调超20%。 在业内人士看来，这些个股既有较好的盈利能力，且未来成长性较好，同时得到了较多的机构背书，但 因受市场行情或其它因素拖累导致股价超跌，其中或暗藏"错杀股"。 证券时报记者陈见南 进入10月以来，A股市场风格分化显著。从申万风格指数表现来看，低价股指数、低市盈率指数、低市 净率指数均大涨超3%，而中高市盈率指数、高市净率指数、高价股指数等均大跌超7%。这表明10月份 A股市场热点主要集中在以红利风格为代表的低估值类股票，成长类股票相对表现较弱。 华金证券研报指出，复盘历史，影响12月科技成长行业表现的核心因素是跨年行情是否提前开启、基金 调仓、美股映射、流动性等。当前来看，今年12月科技成长行业可能出现配置时机。一是今年跨年行情 在12月中下旬可能开启：首先，12月中下旬中央经济工作会议将召开；其次，12月中旬美联储大概率降 息；最后，年底部分资金结算完可能提前布局明年行情。二是今年四季度基金调仓对科技影响可能不 大。三是 ...

Quantitative Models and Construction Methods 1. Model Name: Liquidity Impact Coefficient Model - **Model Construction Idea**: This model measures the liquidity impact of index adjustments on individual stocks by calculating the ratio of net fund flows to the stock's recent average daily trading volume[12][13] - **Model Construction Process**: The liquidity impact coefficient for a stock is calculated as follows: $$ impact_{i} = \sum_{k=1}^{N} \frac{\Delta weight_{k,i} \times AUM_{k}}{amt\_avg_{i,20}} $$ - \( \Delta weight_{k,i} \): Estimated weight change of stock \( i \) in index \( k \) - \( AUM_{k} \): Total assets under management of passive products tracking index \( k \) as of the end of November - \( amt\_avg_{i,20} \): Average daily trading volume of stock \( i \) over the past 20 trading days as of the end of November[12][13] - **Model Evaluation**: The model provides a quantitative framework to estimate short-term liquidity shocks caused by index adjustments, but it is subject to data discrepancies and assumptions, which may lead to deviations from actual results[13] --- Model Backtesting Results Liquidity Impact Coefficient Model - **Top 5 Stocks with Highest Positive Impact Coefficients**: - Zhangjiagang Bank (002839 CH): 11.55[15] - Jiangzhong Pharmaceutical (600750 CH): 11.44[15] - Tower Group (002233 CH): 11.04[15] - Jichuan Pharmaceutical (600566 CH): 10.14[15] - Zhengbang Technology (002157 CH): 9.99[15] - **Top 5 Stocks with Highest Negative Impact Coefficients**: - Shenzhen Expressway (600548 CH): -24.95[16] - Vanward Electric (002543 CH): -20.90[16] - Aviation Materials (688563 CH): -14.06[16] - Huaxi Biology (688363 CH): -10.81[16] - Ninghu Expressway (600377 CH): -10.54[16] --- Quantitative Factors and Construction Methods 1.
