The 1430s decision to end maritime exploration is the case study. Under the Yongle Emperor, Admiral Zheng He had led seven great expeditions to Southeast Asia, India, Arabia, and East Africa between 1405 and 1433, commanding fleets of hundreds of ships and tens of thousands of sailors. When the emperor decided to end the voyages, the treasure ships were burned, records were destroyed, and the construction of vessels with more than two masts was forbidden. The decision stuck. There was no competing harbor, no rival court, no alternative jurisdiction where Chinese shipwrights could relocate. The decision was final because the authority was total.
The contrast with Europe's fragmented competition is Landes's fundamental structural point. When European authorities suppressed innovations, the suppressed migrated; when the Chinese emperor suppressed innovation, the suppressed had nowhere to go. The European miracle was produced by the absence of the specific strength that could kill innovation across an entire civilization. China's strength — centralized, effective, uncontested — was its civilizational weakness.
For the AI age, China's 2026 position is structurally analogous to China's 1500 position. Extraordinary technological capability. World-class engineering talent. Enormous investment in AI infrastructure. And a political system centralized enough to suppress lines of inquiry, applications, and uses of AI that the central authority deems threatening — which is precisely the configuration that, in Landes's analysis, has historically prevented sustained, broad-based innovation. The implication is not that authoritarian systems cannot innovate — they can, and China's AI achievements demonstrate this — but that they innovate within boundaries set by authority, and those boundaries are determined not by what would produce broadest prosperity but by what serves the interests of authority.
The Chinese stagnation puzzle has been a central question in comparative economic history since Max Weber. Landes's particular framing — centralized authority as the structural disadvantage — was developed across his major works and remains contested by scholars like Kenneth Pomeranz who emphasize contingent rather than structural explanations.
The Needham Question. Joseph Needham's framing of the puzzle — why, given China's technological precocity, did it not produce modern science and industrialization?
Centralized authority as disadvantage. The same political structure that enabled Chinese administrative capacity enabled the suppression of innovations that threatened social stability.
No alternative harbor. Innovation requires somewhere for suppressed innovators to go; when authority extends uniformly across a civilization, there is nowhere.
AI-age analogue. Authoritarian innovation operates within boundaries set by authority; the boundaries are determined by power, not by what would produce broadest prosperity.
Kenneth Pomeranz and the California School argue that the European-Chinese divergence is substantially explained by coal geography and New World resources rather than cultural or institutional factors. Landes acknowledged these factors while insisting they were insufficient as complete explanations.
