你有没有发现一个很有意思的现象：五大国家级城市群，可在国际上被公认为"世界级"的，只有一个长三角。GDP不差，城市名气不小的珠三角，为啥总差 临门一脚？ 想象一下，摆在你面前两张棋盘，一张是大号的，另一张小一半。下同样的棋，哪张更能容得下更多变化？这就是长三角和珠三角的差别。 长三角囊括江苏、浙江、安徽、上海，35.8万平方公里，27座城市。以上海为核心，南京、杭州、合肥、苏州等城市环绕，棋局庞大。 珠三角呢？香港、澳门加上广东9市，合计才5.6万平方公里。腹地小了不止一点点。长三角的面积是珠三角的6倍，这意味着更广阔的经济纵深和人口资源 支撑。 在我看来，判断城市群实力，不光看总量，还要看分布均衡度。 2022年，长三角有8座万亿GDP城市：上海、南京、杭州、苏州、宁波、无锡、合肥、南通。 珠三角只有广州、深圳、佛山、东莞4座，加上香港才5个。 差距不算天壤之别，但长三角是"群星闪耀"，珠三角更像"头重脚轻"。深圳、广州很亮眼，可腰部城市支撑力不足。 换句话说，长三角像一支多点开花的球队，而珠三角更依赖明星球员。一旦少了"巨星"，整体战斗力就会下降。 走过长江口的人会明白，这里真的是中国最黄金的地段。长江作 ...
