那时候的全球经济，就是美日双雄的天下。美国的企业垄断着金融、能源和科技领域，日本则在汽车、电子、精密制造上独树一帜，前10名里日本就占了6 席，三菱商事、三井物产这些综合商社，在全球贸易中话语权十足。而咱们的3家企业，只能在榜单末尾徘徊，那时候没人敢想，30年后，这份格局会被彻 底改写。 谁也没想到，短短三十年，风水轮流转。2025年最新的榜单一出来，再回头看当年的差距，真的让人感慨万千。现在的格局早已不是美日双强，而是中美双 雄并立，日本则一步步褪去光环，彻底沦为第三梯队。 咱们的崛起，不是一蹴而就的，而是一步一个脚印走出来的。早期上榜的都是能源、金融、基建类央企，比如国家电网、中石油，靠规模站稳脚跟；后来， 比亚迪、宁德时代、拼多多这些民企异军突起，比亚迪从2022年首次上榜，短短几年就跻身百强，拼多多更是上榜即逆袭，排名一路飙升。 | 国内排名 | 公司名称 | 营业收入(亿元) | 利润 亿元 | 世界邦 | | --- | --- | --- | --- | --- | | 1 | 国家电网有限公司 | ¥ 42,322.24 | ¥ 775.19 | 50 | | 2 | 中国石油天然气集团有限公 ...
