本周数据平台本月监管部门通报最新动态:本月行业协会披露研究成果,中日韩无一线、二线、三线城市区别有多大？

在全球化的背景下，中日韩三国作为亚洲的三大经济体，其城市体系的发展差异引起了广泛关注。在讨论中日韩城市体系时，常常会提到“一线”、“二线”、“三线”等概念。那么，这些城市之间的区别究竟有多大呢？ 首先，我们来了解一下“一线”、“二线”、“三线”城市的定义。一般来说，一线城市指的是国家或地区经济、文化、交通等方面最为发达的城市，如中国的北京、上海，日本东京，韩国首尔等。二线城市则是指具有较高经济实力和一定发展潜力的城市，如中国的广州、深圳，日本大阪、名古屋，韩国釜山等。而三线城市则是指经济发展水平相对较低，但具有一定基础的城市。 一、经济发展水平 在经济发展水平方面，一线城市的优势最为明显。以中国为例，北京、上海等一线城市经济总量巨大，人均GDP远超全国平均水平。相比之下，二线城市如广州、深圳等，虽然经济发展迅速，但与一线城市相比仍有差距。至于三线城市，其经济发展水平相对较低，但近年来随着国家新型城镇化战略的推进，部分三线城市经济实力逐渐提升。 二、基础设施与公共服务 在基础设施与公共服务方面，一线城市拥有更为完善的城市配套设施和优质的公共服务。例如，交通网络、教育资源、医疗卫生等方面，一线城市均处于领先地位。二线城市在基础设施和公共服务方面相对较好，但与一线城市相比仍有不足。三线城市在基础设施和公共服务方面相对薄弱，但随着城市建设的推进，这一状况正在逐步改善。 三、人口规模与人口素质 一线城市的人口规模较大，人口素质较高。以北京、上海为例，这些城市汇聚了大量高素质人才，为经济发展提供了强大动力。二线城市人口规模适中，人口素质较高，但与一线城市相比仍有差距。三线城市人口规模较小，人口素质相对较低，但随着城市化进程的加快，这一状况也在逐步改善。 四、城市文化 在文化方面，一线城市具有丰富的文化底蕴和独特的城市文化。如北京作为国家的政治、文化中心，拥有众多的文化遗产和艺术资源。二线城市在文化方面也有一定优势，但与一线城市相比略显不足。三线城市在文化方面相对薄弱，但随着城市文化的传承与创新，这一状况也在逐步改善。 总之，中日韩三国的一线、二线、三线城市在经济发展水平、基础设施与公共服务、人口规模与人口素质、城市文化等方面存在一定差距。然而，随着城市化进程的推进和区域协调发展战略的实施，这些差距正在逐步缩小。未来，三国城市体系将更加完善，为地区乃至全球经济发展注入新的活力。

TMTPOST --   Chinese telecommunications giant Huawei unveiled a sweeping expansion of its artificial intelligence computing ambitions on Thursday, announcing new supercomputing systems powered by its in-house Ascend chips. The move signals escalating competition with U.S. chipmaker Nvidia, the global leader in AI processors.AI-generated imageAt its annual Huawei Connect conference in Shanghai, the company introduced the forthcoming "Atlas 950 SuperCluster," which it said will begin rolling out as early as next year. The announcement underscores Huawei ’ s determination to challenge U.S. dominance in advanced AI hardware despite Washington ’ s tightening export controls on semiconductors."The competition has undeniably arrived and is gaining momentum," an Nvidia spokesperson said. "Customers will choose the best technology stack for running the world ’ s most popular commercial applications and open-source models."U.S. restrictions have cut China off from the most advanced chips needed to train large-scale AI models, forcing Chinese firms to rely on domestically developed processors or stockpiles of older foreign components. Huawei, long targeted by U.S. sanctions, has turned to large-scale clustering of its less powerful but increasingly refined Ascend processors. By combining vast numbers of these chips in interconnected networks, the company aims to match or surpass the performance of systems built on Nvidia ’ s hardware.Huawei said it plans to release three new versions of its Ascend chips through 2028, pledging to double computing power with each iteration. At the base level, its new Atlas 950 supernode will connect 8,192 Ascend chips. A full Atlas 950 SuperCluster would integrate more than 500,000 chips.A future upgrade, the Atlas 960 system slated for 2027, is projected to support nearly 15,500 chips per node and scale to more than 1 million Ascend processors across a full supercluster. Huawei claimed these would represent the world ’ s most powerful AI systems by raw computing power.Huawei did not shy away from comparisons with its American rival. Eric Xu, the company ’ s vice chairman and rotating chairman, said the Atlas 950 supernode would deliver 6.7 times more computing power than Nvidia ’ s upcoming NVL144 system. He went further, predicting Huawei would "be ahead on all fronts" compared with Nvidia ’ s 2027 offering — and claimed the Atlas 950 SuperCluster would even exceed the computing capacity of Elon Musk ’ s xAI Colossus project.While independent verification of Huawei ’ s claims is limited, industry experts said the company ’ s ambition is clear."Huawei ’ s announcement on its computing breakthrough is well timed with recent increasing emphasis by the Chinese government on self-reliance on China ’ s own chip technologies," said George Chen, partner and co-chair of the digital practice at The Asia Group. While noting that Huawei might be overstating its technical edge, he added, "the ambition to be a world AI leader cannot be underestimated."Research from SemiAnalysis earlier this year found that Huawei ’ s CloudMatrix system outperformed Nvidia ’ s equivalent despite each Ascend processor offering only about one-third the power of an Nvidia chip. The advantage came from scale: Huawei deployed roughly five times as many chips in its clusters."Computing power has and will continue to be the key for AI," Xu emphasized during his keynote speech in Shanghai.Huawei ’ s new announcements build on earlier efforts. Two years ago, it introduced the Atlas 900 SuperCluster, which it still markets with "thousands" of Ascend chips. On Thursday, the company said it had already deployed more than 300 Atlas 900 A3 supernodes to over 20 clients across telecoms, manufacturing, and other sectors.This momentum reflects a broader push within China to substitute foreign technology with homegrown alternatives. Beijing has increasingly pressed domestic firms to use local suppliers and invest in national semiconductor capabilities. Huawei ’ s breakthroughs are likely to be touted as proof of progress in these efforts.Huawei ’ s offensive comes as Nvidia faces growing headwinds in China, once one of its most important markets. Earlier this week, China extended an antitrust probe into the U.S. company over alleged monopolistic practices. On Wednesday, Nvidia ’ s shares fell more than 2% after the Financial Times reported that Beijing had ordered Chinese tech giants to halt testing and purchases of the RTX Pro 6000D, one of Nvidia ’ s new AI-focused chips.Nvidia Chief Executive Jensen Huang expressed frustration over the developments. "I am disappointed to hear this news," he told reporters, while reiterating that Huawei represents a "formidable" competitor.The geopolitical context adds another layer of complexity. The U.S. and China concluded trade talks in Spain this week that reportedly included discussions over the fate of TikTok, the video app owned by Beijing-based ByteDance. But technology co
