青侨阳光医药投资 - 行业思考 1 医药出海 中国创新药市场在过去10年迎来高速发展，按我们的估计，创新药在中国药品市场中的比重已经从约5%增加 到10%以上，整个市场规模也从小几百亿增长到接近2000亿的体量，已经足以支撑起一批数百亿乃至一两千亿 人民币市值的上市药企。 但这样的规模体量放在海外创新药市场面前依然是不够看的：2023年海外创新药占药品总市场的比重接近 60%，年销售规模折合人民币高达6-7万亿人民币，仅仅一款帕博利珠单抗2024全年超2000亿人民币的销售额 就能超过整个中国创新药行业的体量，只是美国一个国家近3万亿的创新药市场就比整个中国创新药行业大10 多倍。 也就是说， 中国创新药通过10年高速发展，在全球创新药市场的比重也就从1%-2%的份额提升到3%左右， 即使以每年15%-20%的速度再发展10年，中国市场占全球创新药的比重也很难超过10% 。 是专注于国内这3%的市场，还是打通国外那97%的市场？这里的选择是不言而喻的。 对于每一家有着远大志 向的创新药企来说，"出海"都是必选项，因为那里的天地远比国内更宽广。 中国创新药的出海之路有几个关键节点。 药监政策层面上： 海外市场准 ...
