How have the sources of companies' competitive advantage changed in a flattened world?

Hey friend, that's an excellent and really interesting question. It's essentially the core question every businessperson in our era is pondering. Let me share my thoughts, and I’ll try to put it in plain language.

Think back to the old days when so-called "moats" (a company's competitive advantages) were like actual castles.

• High, Thick Walls: You had massive factories, large equipment, and substantial capital that others didn't. Small companies couldn't compete; they couldn't even afford the bricks to build such walls.
• Prime Location: Your castle was built on the only critical trade route, forcing everyone to pass through it. For instance, you had the best storefront location in a city, or you monopolized sales channels in a region.
• Deep Moat: You held exclusive patents or secret technologies that others couldn't learn or replicate, unable to even find a way to imitate them.
• Information Asymmetry: People outside the castle had no idea how things worked inside, didn't know your actual cost of goods, and simply had to pay whatever price you set.

But now, the phrase "the world is flat" essentially means that the bulldozers have arrived.

The internet, global logistics, and freely flowing capital act like giant bulldozers, leveling the once towering mountains, moats, and canyons.

• Walls? You have big factories? I can use Foxconn for contract manufacturing, potentially doing it better and faster. Need huge capital? Now there's venture capital, crowdfunding – a single great idea can attract money from all over the world.
• Location? Companies like Amazon, Taobao, and Shein show us that it doesn't matter where the warehouse is, as long as delivery can reach there. My business can be done globally.
• Moat? Much technology is open-source now, talent flows globally. The new technology you launch today might have an affordable alternative available in Shenzhen's Huaqiangbei market tomorrow. Information barriers have nearly vanished. Consumers compare prices and read reviews online before buying; making money through "information asymmetry" is getting harder and harder.

So, since the old-style moats are becoming obsolete, what do the new moats look like? They've shifted from visible "hard assets" to invisible "soft power."

The New Era "Moat": From Brick Walls to Mind Walls

1. Brand & Culture: From "Recognizing the Product" to "Recognizing the Brand"

This is the most crucial point. When product functions are similar, why are you willing to pay more for an iPhone, wear Nikes, or drink Starbucks?

• You're not buying just function; you're buying a "feeling" and "sense of identity." Apple represents innovation, simplicity, and coolness; Nike embodies the "Just Do It" spirit of striving. This kind of brand culture can't be bought with money, and it's the hardest thing to imitate. It's built in users' minds – an invisible "wall in the mind." Competitors can copy your product, but they can't replicate the trust and affection your users have for you.

2. Network Effects: From "I Have More" to "We All Have It"

This one is easy to understand. Why use WeChat? Because all your family and friends are on it. Even if a better messaging app appears, switching would be a hassle because your entire social network is anchored on WeChat.

• The more users a platform has, the more valuable it becomes to each user. This attracts new users and makes existing users reluctant to leave. That's the network effect. Taobao, Didi, Meituan, and Facebook all built enormous moats this way. New competitors, even with equally good products, struggle to "move" users away.

3. Extreme Efficiency & Speed: From "Big" to "Fast"

In a flat world, size alone doesn't guarantee success; speed does.

• The core principle is the "fast fish eats the slow fish." Classic examples are ZARA and Shein. Traditional clothing companies might take six months from design to retail. ZARA and Shein can shrink that cycle to a staggering few weeks, even days. They rapidly capture the latest trends, design, produce, and stock immediately. If something doesn't sell, it's pulled and replaced. This extreme supply chain management and market responsiveness is their moat. Large corporations struggle to pivot quickly, but these companies nimbly adjust direction.

4. Data & Algorithms: From "Guess What You Like" to "Knowing You Better Than You Know Yourself"

This might be the most formidable moat of the digital age.

• The more you use it, the more it understands you, providing better service and making you increasingly reliant. Think TikTok/Douyin's recommendation algorithm. It analyzes every action – watching, liking, commenting – to push content you'll likely enjoy, keeping you endlessly scrolling. Amazon and Taobao's recommendation systems work similarly. Their massive user data reserves and the powerful algorithms processing this data create a barrier almost impossible for newcomers to overcome.

5. Ecosystem: From "Selling a Product" to "Selling a Whole World"

This tactic is more sophisticated: it "locks" you into an ecosystem.

• Once you use one of my products, you find using my other products is incredibly convenient. Apple is the prime example. Buy an iPhone, and you'll see how easy it is to transfer files using a Mac, take calls on an Apple Watch, or sync photos via iCloud. Want to switch to an Android phone? You might have to change your watch, computer, and cloud service – a high switching cost. Huawei's HarmonyOS ecosystem follows the same logic. Once built, user loyalty within such an ecosystem becomes extremely high.

To Summarize

Simply put, the shift is:

Therefore, in today's "flat world," the concept of a "moat" hasn't disappeared. It has simply evolved from visible brick walls and water-filled ditches into invisible, intangible soft power that is far harder to cross. While building a physical castle might take years, establishing a brand deeply rooted in people's minds, a vast user network, or a hyper-efficient ecosystem could take a decade or more. But once built, it will be more formidable than any physical wall.
