稳步扩大产业规模。产业规模的稳步扩大是产业安全的压舱石，是不能弱化的"外功"。在从中高收入国 家迈向高收入国家的过程中，保持较大规模的工业和制造业是成功跨越"中等收入陷阱"的重要条件。我 国制造业总体规模已经连续15年居全球第一，是全球唯一拥有联合国产业分类中全部工业门类的国家， 在把握历史机遇实现跨越式发展中，产业部门展露出全球独有的规模优势和体系优势。例如，从引进第 一列高速动车组到具有完全自主知识产权的"复兴号"投入商业运行只用了13年；大飞机等装备制造实现 重大突破；集成电路、人工智能、量子通信等领域不断取得新成果；等等。这些无不与规模优势和体系 优势相关。未来，提升产业发展安全水平需要继续扩大产业规模，保持工业和制造业占国民经济的比重 基本稳定。 推动产业提质升级。若依靠低水平重复投资的方式拉动产能扩张，会造成产能利用率不足和内卷式竞 争。这反而会危害产业安全。因此，应推动产业提质升级，依靠产业结构高级化促进提升产业安全水 平。一是提升产业发展的数字化水平，把数字产业培育成为新支柱产业，加强数字技术在传统产业部门 的渗透和深度融合。例如，2024年广东省深圳市制造业增加值约占地区生产总值的1/3，不 ...

Core Viewpoint - The historical significance of CRRC Qingdao Sifang Co., Ltd. (CRRC Sifang) in the development of China's railway industry and its role in the labor movement in Qingdao is highlighted, showcasing its evolution from a labor movement base to a modern manufacturing hub for rail transport equipment [1][2][4].
