Business Moat
Business moat is a company’s durable competitive advantage, but E160.一个价值投资者的 20 年回顾：求积分，求胜率，求时间 stresses that moats live and die with their era. The same factor that once made a company strong can weaken as technology, distribution, input costs, regulation, or consumer behavior changes.
Key Claims
- Moats can come from cost leadership, scale economies, scope economies, production-management know-how, brand, channels, user scale, stickiness, or network effects.
- Gradual innovation may strengthen incumbents when they can adapt through scale and process, while disruptive innovation can shift value to new entrants.
- Manufacturing stability differs by industry; traditional chemicals may be more stable than some new-energy segments if value delivery and technology routes change more slowly.
- Channel migration can change moat quality: for home appliances, offline channel advantages may not transfer cleanly into online distribution.
- Software moats are framed around user scale, high stickiness, and network effects rather than only code features.
- A moat only matters to Value Investing when it protects future cash flows enough to justify price and position size.
