经济商誉 / 护城河识别

R — 原文 (Reading)

"GEICO's cost advantage is like a moat protecting a much-sought-after business castle." (1986) "Economic goodwill does not, in many cases, diminish. Indeed, in a great many instances it actually grows in value over time. In character, economic goodwill is much like land." (1999)

I — 方法论骨架

经济商誉 = 品牌+市场地位+定价权+客户忠诚度 → 使企业能在极少额外资本下增长利润。

关键区分:

  • 会计商誉会摊销减少;经济商誉往往随时间增长(如土地)
  • 经济商誉的核心标志:不需要大量资本投入就能增长利润
  • 护城河 = 保护经济商誉不被侵蚀的屏障(成本优势/品牌/网络效应/切换成本/许可)
  • 商品企业(无护城河):只有产能短缺时才能赚好钱

A1 — 书中的应用
