Question 1

How did China grow so fast?

Accepted Answer

China's growth combined several factors: massive surplus labor moving from agriculture to industry, very high savings and investment rates (often exceeding 40% of GDP), technology transfer from foreign direct investment, export-oriented manufacturing scaling through global supply chains, and a state that was pragmatic enough to experiment with markets while maintaining political control. Crucially, China's size meant these factors operated at an unprecedented scale.

Question 2

Is China's economy really the second largest in the world?

Accepted Answer

By market exchange rates, China's GDP is approximately $18 trillion, second only to the US at about $28 trillion. But by purchasing power parity (PPP), which adjusts for price differences, China surpassed the US around 2014 and is now the world's largest economy. Which measure matters depends on context: market rates matter for trade and finance, PPP matters for living standards and domestic economic weight.

Question 3

What is the middle-income trap and is China stuck in it?

Accepted Answer

The middle-income trap describes countries that grow rapidly to middle-income status but then stall, unable to compete with low-wage economies on cost or with advanced economies on innovation. China's GDP per capita is around $13,000 -- roughly where many countries have historically stalled. China's enormous investment in technology, education, and industrial upgrading is designed to break through, but demographics, debt, and geopolitical isolation create headwinds that previous success stories like South Korea and Taiwan did not face.

Question 4

How does the US-China trade war affect the global economy?

Accepted Answer

The US-China trade war, which began with tariffs in 2018 and has since expanded into technology restrictions, investment screening, and supply chain decoupling, is fragmenting the global trading system. It forces other countries to choose sides, raises costs for consumers and businesses, disrupts supply chains, and may permanently reduce the efficiency gains from globalization. The IMF estimates that severe fragmentation could reduce global GDP by up to 7%.
