大额采购资金经8家贸易商"季度循环"、股权投资的资金去向不明,*ST金泰(300225.SZ)近15亿资金 异常流转的问询回复陷入争议。 *ST金泰在8月12日披露的监管问询回复中称,2024年,该公司为规避原材料价格上涨风险,采取"战略 备库"措施,向贸易商支付超9亿元资金,实际采购金额仅2900余万元,资金流向与采购需求严重背离。 其中,供应商部分资金流向非经营实体,与芮奈贸易(上海)有限公司(下称"芮奈")的资金往来涉嫌 存在非经营性资金占用情况。 不仅如此,*ST金泰去年还向深圳怡钛积科技股份有限公司(下称"怡钛积")支付了两笔股权投资款, 合计金额4.6亿元,资金最终流向的、真实目的不明。但该公司一名董事长称,这些资金中的大部分, 经层层划转,最终流向了配资公司。 对于这些回复内容,该公司3名董事并不认同,并投了反对票。董事刘锐明认为,此次回复"避重就轻, 罔顾事实",战略备库供应商是受同一主体控制的资金通道,公司管理层与实际控制人裴剑等人勾结, 以不干涉采购部之由行侵占公司资金之实。 另据8月13日公告,*ST金泰董事会审计委员会认为,该公司2024年的战略备库行为,已不符合正常采 购锁价的商业实 ...

在财报发布后的业绩交流会上,腾讯管理层谈到AI时表示,公司着眼让AI提高现有业务的效率,例如广告、游戏、金融科技,随着时间推移,也会进一步 探索AI变现模式。至于AI运算依托的芯片,管理层表示,芯片进口的情况还需要观察,腾讯目前有足够的芯片来做训练并升级现有模型,推理方面则有不 同的芯片选择。在软件方面,公司也会进一步改进,以提高推理效率,从而减少对芯片能力的依赖。 腾讯也为AI增加了相应开支。该季度腾讯一般及行政开支319亿元,同比增长16%,主要是由于支持AI相关业务发展而增加的研发开支和雇员成本增加。该 季度资本开支同比增长119%至191亿元,主要用于对IT基础设施、数据中心等的投入。 此前一日,腾讯发布2025年第二季度财报。该季度腾讯营收1845.04亿元,同比增长15%,经营利润(Non-IFRS)692.48亿元,同比增长18%。该季度毛利率 57%,同比增长4个百分点。 游戏方面,该季度腾讯国际游戏收入188亿元,本土游戏收入404亿元,分别同比增长35%和17%。新游戏《三角洲行动》今年7月平均日活跃账户数突破 2000万,该游戏位于行业日活跃账户数前五、流水前三。 8月14日盘中,腾讯控 ...
特朗普冲击下的全球化何去何从
Di Yi Cai Jing· 2025-08-14 06:00
相比于过去的"意大利碗面式全球化",今天我们面临更复杂的地缘政治环境和更盛行的贸易保护主义, 全球化的碎片化趋势可能正在向着更具封闭性、分化特征的方向升级。 "若中美两国商业联系显著下降,可能引发何种情景?" 近期,笔者在美国参会时现场投票有这样一个议题。25位与会专家的投票结果值得玩味:首先,"中国 将被孤立,美国则与其他国家建立更紧密联系"这一选项无人问津。相反,"美国将被孤立,而中国加强 与其他国家的关系",没有中国专家选择此选项,但有趣的是,55%的美国专家倾向于这一观点。再 者,"中美两国都将被孤立,而其他国家基本上仍保持一体化",这一看法未得到任何中美专家的支持。 最后,"全球商业活动减少,全球经济走向碎片化",这个选项得到了所有中国专家以及45%美国专家的 认可。 专家观点不一定就是答案,但这几个选项引发了笔者深思。 企业层面的"最小化成本"战略 与美国企业高管进行交流,使笔者对上面的问题有了新的体会。 首先,重要企业转向了"最小化成本"(Bare Minimum)的战略,即通过最小化成本来应对不确定性。 由于特朗普政府的政策,尤其是关税政策的多变性,跨国公司很难基于这些政策做出长期规划,因为新 ...

茅台五星新品上市一周价格炒至翻倍,文创酒“炼金术”路在何方
Di Yi Cai Jing· 2025-08-14 04:56
茅台五星70周年纪念酒遭爆炒 这款茅台五星70周年纪念酒是为庆祝五星商标上市70周年而推出。尽管其在i茅台平台上的发售价高达 7000元,但区别于传统文创产品,该产品采用了全球限量25568瓶发售的方式,同时每瓶酒对应1954年5 月1日到2024年4月30日之间的唯一日期编码。 这种稀缺性让黄牛们看到了久违的套利机会。正式销售当天,所有纪念酒仅2秒便告罄。 记者在部分二手平台上看到,发布转让茅台五星70周年纪念酒信息的用户不在少数,价格水涨船高,整 体叫价在1.1万到2万元不等。 贵州酒商柴先生告诉第一财经记者,有生肖酒价格先涨后跌的先例,他不敢多留,于8月12日以9500元/ 瓶的价格将手中20多瓶全部售出。但8月13日就有同行以1.3万元/瓶求货,他对此后悔不已。 由于二手市场价格快速飙升,也在黄牛圈引发混乱。记者了解到,在70周年纪念酒推出前夕,黄牛圈普 遍预期上市后价格在9000元/瓶左右,甚至提前收取了定金。但随着酒价暴涨,部分黄牛拿不到货,不 得不退款并赔偿定金。 值得注意的是,买卖双方关注的焦点往往并非酒体本身,而是集中在酒瓶上的日期编号。部分消费者专 门选择特定日期(如生日)带号求购,用于收 ...
