#477 – Keyu Jin: China’s Economy, Tariffs, Trade, Trump, Communism & Capitalism

In plain words

This podcast features economist Keyu Jin explaining how China's economy really works. She argues it's not centrally commanded but driven by local officials competing on GDP growth, calling it 'mayor economy.' On markets, she says US tech restrictions (like chip export bans) backfired by forcing China to innovate faster. Key mentions: DeepSeek (AI firm that broke through despite sanctions), Huawei (stronger after being sanctioned), and Xiaomi (phone maker that sold 270,000 EVs in one day).

At a Glance

London School of Economics economist Keyu Jin appeared on the podcast, using her book The New China Playbook as a framework to systematically explain the core features of China's economic model and refute common Western misconceptions. The most significant judgment in the entire episode is that Keyu Jin believes the US technology blockade against China (e.g., export controls) has not only failed to contain China but, through a "crisis innovation" effect, has unexpectedly accelerated China's independent R&D in areas like semiconductors and AI, proving counterproductive.

China's "Mayoral Championship": A Unique Blend of Political Centralization and Economic Decentralization

Keyu Jin argues that one of the West's biggest misconceptions is that China's economy is commanded top-down by a few individuals. She points out that the actual operation of China's economy is "highly centralized politically, highly decentralized economically." The core driving force comes from intense competition among local officials (mayors, governors), which she calls the "mayoral economy."

  • Incentive Mechanism: The central government holds the power over the promotion, rewards, and punishments of local officials. For a long time, GDP growth was the core "yardstick" for measuring the performance of local officials. To get promoted, officials would engage in GDP competition with officials from neighboring cities.
  • Operational Model: This mechanism fosters strong execution capabilities. For example, to drive economic growth, local officials actively attract investment, support local enterprises (especially private ones), and even coordinate relationships between banks and debtors. Keyu Jin emphasizes: "They (local officials) are so willing to help these private companies because... their incentives are aligned."
  • Double-Edged Sword Effect: This model is effective in mobilizing resources and coordinating supply chains during the initial "from 0 to 1" phase (e.g., new energy vehicles, solar energy), achieving a "big push." However, once an industry matures, the problems of inefficient resource allocation and capital waste under government guidance become apparent. Keyu Jin notes: "You don't need 80 cities to all make their own EV brand... But perhaps it was precisely this incentive that got things started."
  • Current Challenge: As the economic goal shifts from "production" to "consumption," the old GDP yardstick is no longer suitable. Keyu Jin believes that incorporating "consumption" indicators into the performance evaluation of local officials would effectively stimulate domestic demand. Using environmental protection as an example, she points out that once the central government made it a "punitive" indicator, the number of blue-sky days in Beijing increased rapidly.

"Crisis Innovation": How the US Technology Blockade Unexpectedly Accelerates China's Tech Self-Reliance

Keyu Jin proposes that DeepSeek's success is not accidental but a typical product of "crisis innovation." She argues that the US technology blockade (e.g., sanctions against Huawei and SMIC) has instead triggered a "whole-nation system" response in China, accelerating its technological catch-up.

  • Historical Analogy: She compares this phenomenon to how the historical "Continental Blockade" unexpectedly spurred the British Industrial Revolution, and how the Spanish blockade of Portugal forged Portugal's powerful navy. Keyu Jin asserts: "These blockades don't work... You push them into a corner, and they only become more motivated."
  • Specific Cases: Huawei emerged "stronger than ever" after being sanctioned; US export controls on chips directly led to China significantly improving its semiconductor localization capabilities in a short period. She attributes this to the lack of motivation for independent R&D among Chinese companies when in their "comfort zone," while external threats create a "life-or-death" urgency.
  • Differences in Innovation Models: Keyu Jin distinguishes between two innovation models. The US excels at disruptive breakthroughs "from 0 to 1," while China excels at scaling, cost reduction, and commercial diffusion "from 1 to N." She believes DeepSeek represents a "scale-based, cost-reduction-driven leading technology" model, which could be equally powerful, or even more effective, in driving technology普及 and productivity gains.

US-China Rivalry: Trade War, Tariffs, and Red Lines in Negotiations

Keyu Jin analyzes Trump's tariff policy from an economic perspective, deeming it ineffective and harmful. She points out that tariffs did not shrink the US trade deficit because the deficit is a result of macroeconomic savings-investment imbalances, not a trade issue. She argues the US should meet the challenge by enhancing its own competitiveness (e.g., investing in R&D, education, attracting talent) rather than punishing foreign countries.

  • China's Negotiation Strategy: Keyu Jin summarizes China's response strategy as "reciprocal, mutual benefit, and realistic." China will not make unilateral concessions without the US lowering its tariffs. She believes China has drawn clear "red lines" in negotiations:

1. Do not confuse economics with politics: Issues like Hong Kong and Taiwan are not within the scope of trade negotiations.

2. Do not challenge the core system: Discussions about changing China's "state-private hybrid model" are off the table.

3. Do not touch technology security: Any topic that challenges China's technology security is not up for discussion.

  • Feasible Deal Space: She believes a realistic agreement could involve China increasing purchases of US goods, opening up its service sector (e.g., finance, banking), and strengthening intellectual property protection, with the US reciprocally lowering some tariffs. Keyu Jin emphasizes: "Respect is crucial... You can push China to do many things, but understanding and respect are vital. 'Giving face' is very important."

Position Moves

Position Guest's Stance Key Data
DeepSeek Bullish (as a model of "crisis innovation") Achieved a breakthrough in AI, surprising the world, proving the US-China tech gap is smaller than expected.
Huawei Bullish (as evidence of sanctions' counterproductive effect) Emerged "stronger than ever" after sanctions; US engineers report being very happy working at Huawei.
Xiaomi Bullish (as evidence of China's speed) Successfully transformed from a phone maker; its new EV sold 270,000 units in a single day.
Alibaba/Jack Ma Neutral (as a case study of entrepreneur-government relations) Ant Group's IPO was halted for engaging in unregulated banking activities. Jack Ma himself was "too brilliant" and chose to live in Japan.
Evergrande Risk Warning (as a case of excessive corporate diversification) A real estate company bought a football club and ventured into EVs, investing in areas unrelated to its core business.
TSMC Neutral (as a key node in global semiconductors) Its manufacturing capabilities are extremely difficult to replicate; US efforts to replicate TSMC outside of Taiwan are "very, very slow."

Judgments Worth Remembering

1. The "mayoral economy" is key to understanding China's growth miracle. Economic decentralization under political centralization, combined with the GDP-centric official promotion tournament, has created globally rare execution efficiency and competitive drive.

2. The US technology blockade is counterproductive. Export controls and sanctions have not contained China but, through the "crisis innovation" effect, have unexpectedly accelerated China's independent R&D in semiconductors and AI.

3. China's innovation model is "1 to N," not "0 to 1." China excels at using its advantages in scale, speed, and cost to commercialize and mass-diffuse existing technologies. This model is equally crucial for productivity gains.

4. Chinese entrepreneurs face a contradiction between "short, flat, fast" and long-termism. On one hand, there is political continuity for long-term planning; on the other, a speculative mindset of "short, flat, fast" (short-term, flat hierarchy, quick returns) prevails in business culture, which is changing as the economy slows.

5. The bottom line in US-China trade negotiations is "not confusing economics with politics." China is willing to make concessions on opening its service sector and increasing imports, but political issues like Hong Kong and Taiwan, as well as China's core economic system, are non-negotiable.

6. China's economic "weakness" is consumption, not production. Its political-economic model is highly efficient at expanding supply but has structural deficiencies in stimulating personal consumption, rooted in the misalignment of local officials' incentives.

7. The relationship between Chinese entrepreneurs and the government is that "capital must be subordinate to politics." Entrepreneurs can become wealthy but should not challenge the government in terms of political influence. "Don't be the tallest tree" is a survival wisdom.

8. China's one-child policy unexpectedly elevated women's status. As the sole offspring of the family, girls received unprecedented investment in education, leading to a significant increase in Chinese women's bargaining power in the workplace and marriage market.
