1. Core concepts
Digital economy·An economy where data is a key factor of production and platforms plus network effects drive allocation: near-zero marginal costs, concentrated winners, constant cross-boundary attacks.
Traditional competition pits scale and cost; digital competition pits data loops and network effects. More users produce better data, better data improves the product, and the loop accelerates.
2. Four rule changes
| Dimension | Traditional | Digital |
|---|---|---|
| Key factors | Capital, capacity, channels | Data, algorithms, niches |
| Scale logic | Economies of scale | Network effects |
| Boundaries | Intra-industry battles | Cross-border disruption |
| Advantage life | Decades | Short half-life, keep iterating |
Mature technology defends today's base; frontier technology buys tomorrow's ticket. Conflating the two either misses the future or burns the present.
3. Three niches to choose from
Build a platform
＋ Capture network effects and set the rules
－ Winner-takes-most, expensive to ignite
适合 Players with traffic entry or integration power
Ride an ecosystem
＋ Grow fast on someone else's traffic and tools
－ Exposed to platform rules
适合 Firms with differentiated supply
Be a hidden champion
＋ Irreplaceable in a niche, supply many platforms
－ Ceiling tied to industry cycles
适合 Mid-sized firms with technical moats
4. AI as the engine of new productive forces
If the digital economy was about connection, it is now about intelligence. AI turns data into real productivity: predictive scheduling, smart pricing, demand insight. Rebuilding the business with AI is the concrete form of new quality productive forces at firm level.
