帮主郑重:2026五大确定性风口!中长线布局就盯这几条赛道
Xin Lang Cai Jing· 2025-12-13 14:53
朋友们,我是帮主郑重!站在2025年的尾巴上往2026年看,是不是觉得市场热点轮动快得让人眼花缭 乱,手里的钱不知道往哪儿投才稳妥?别急,作为跑了20年财经线、只做中长线的老炮,见惯了风口起 起落落,今天就掏心窝子跟大家唠唠——迷雾之中,主线其实早就藏不住了!刚刚结束的中央经济工作 会议,还有国内外顶尖机构的2026展望,都齐刷刷指向了这几个方向,这可不是短炒的概念,而是决定 未来五到十年国运和财富的超级赛道。 第二个风口,是"新能源与电力体系"的全面升级。这可不是以前单纯的光伏风电了,现在AI数据中心 爆发式增长,全球都可能面临"电力短缺",这既可能推高能源价格,也让整个电力系统必须变得更强 大、更智能。从储能(现在政策允许储能当独立主体参与电力交易,赚钱效应越来越明显)到特高压电 网,再到支撑清洁能源的铜、稀土等有色金属,供需缺口摆在那儿,长期逻辑特别硬。 首先,以"AI+"和"高端制造"为长期核心仓,这是新质生产力的脊梁,波动中要敢于坚守;其次,关 注"再通胀"背景下的周期机遇,全球电力紧张可能给能源、有色金属带来阶段性双击;最后,在喧嚣中 保持冷静,2026年市场会更看重实打实的盈利,不是飘在空中的故 ...
电力竞争将决定未来格局!中国将成为人类史上首个“电力帝国”
Sou Hu Cai Jing· 2025-11-22 11:42
中国的电力需求在过去几十年中稳步增长,尤其是制造业和高科技产业的崛起,推动了对能源的需求飞速上升。 尤其是近年来,新能源汽车产业的迅猛发展以及智能化产业对电力的依赖,使得电力供应成为国家发展的一项战略性问题。 每年,中国各类电站的建设规模逐步扩大,从传统的煤电、核电到新能源的风能和太阳能,电力基础设施建设正在以超乎寻常的速度推进。 中国正加速推动风能、光伏等新能源项目,全球能源格局悄然变化。 从西藏山南风电场到青海光伏电力的远程输送,再到特高压电网的突破,种种迹象表明,中国正朝着成为全球电力"帝国"的目标迈进。 这不仅是为了环保,更是为了确保能源安全、稳定供应,并提升产业竞争力。 为什么在电力已经充足的情况下,我们还要继续加大投资建设电力设施? 中国的能源问题长期以来都是国家战略中的一个"痛点"。 尤其是石油、天然气等传统能源的对外依赖度过高,石油的对外依存度高达70%,意味着我们每使用10桶油,有7桶要从国际市场进口,这使得中国在面对 全球能源市场波动时,显得格外脆弱。 在2022年俄乌冲突爆发后,国际油价飙升,导致国内物流成本增加,甚至连快递费用都因为油价上涨而有所增加。 这种"卡脖子"的局面,迫使中国政 ...
