"Central GDP" isn't a standard metric—it refers to GDP measured in a centrally planned economy. The comparison to the US (market economy) reveals structural contrasts:
| Dimension | Central Planning | US Market Economy |
|---|---|---|
| Resource Allocation | Government directives, quotas | Price signals, supply/demand |
| Pricing | Administered, often below market | Market-determined |
| Ownership | State owns major means of production | Private dominant |
| Incentives | Plan fulfillment, political | Profit, competition, innovation |
| Efficiency | Allocative distortions, shortages | Dynamic, but inequality, externalities |
| Growth Pattern | Mobilization-driven (heavy industry) | Innovation/consumption-driven |
| Data Reliability | Political reporting bias common | Independent statistical agencies |
No pure centrally planned economies remain. Cuba, North Korea, Laos, Vietnam retain planning elements but use market mechanisms. China's "socialist market economy" blends state-owned enterprises (SOEs) with private sector (60%+ GDP).
GDP comparison requires PPP adjustment, quality adjustment, and recognition that "what's measured" differs. The Soviet GNP didn't count environmental degradation; US GDP doesn't count unpaid care work.
