2016-2020年，中国运动鞋服市场上保持领先地位的是耐克和阿迪达斯两家外企，紧随其后的是安踏、 李宁和特步三家本土企业。2020年，这五家企业的市占率之和为69.8%，呈现出明显的"马太效应"。头 部企业凭借品牌优势、技术优势和渠道优势，不断扩大市场份额，而中小品牌则面临着生存困境。 当地时间5月5日，全球第三大运动鞋品牌斯凯奇(Skechers)宣布接受巴西私募巨头3G资本的收购并私有 化退市。3G资本将以每股63美元的现金收购斯凯奇所有已发行股票，较公司15天成交量加权平均股价 溢价30%，交易总额达94.2亿美元。交易完成后斯凯奇将私有化退市成为私人控股公司。斯凯奇有1.29 亿股流通股，以此计算本次交易对价约81.27亿美元。此次交易不仅是全球鞋类行业金额最高的并购 案，也是3G资本继汉堡王、卡夫亨氏后，在消费品领域的又一重磅投资。 斯凯奇退市原因是美国政府掀起的"对等关税"风暴。新关税政策下，一双原本售价1100元的球鞋，如今 消费者要支付近1700元，这让主打"高性价比"的斯凯奇陷入两难境地。若维持原价，企业将面临巨大的 成本压力和利润缩水;若提高售价，又可能失去对价格敏感的消费者群体，市场份 ...
