China became the manufacturing hub of the world through several advantages that reinforce one another, not through cheap labor alone. A very large workforce kept wages low for decades. Dense supplier networks let factories source components within a short distance. Regulation was looser than in older industrial economies. Exports were spared domestic value-added tax, and a managed currency kept Chinese goods competitive abroad. Each factor lowers costs on its own. Together they produced an industrial base that newer low-wage countries have found hard to copy.

How China Became the World’s Factory

The rise started with policy. In 1978, under Deng Xiaoping, China began its “reform and opening” program, which moved the economy away from strict central planning and toward markets and foreign investment. In 1980 the government created Special Economic Zones, Shenzhen among them, where foreign companies could build factories under more flexible rules and lower taxes. Shenzhen sits directly across the border from Hong Kong, which gave early investors access to a major port and financial center.

Through the 1980s and 1990s, foreign manufacturers set up export-oriented plants in coastal provinces, attracted by low wages and government incentives. The second big turning point came in December 2001, when China joined the World Trade Organization. Membership gave Chinese exporters more predictable access to foreign markets and gave multinational companies more confidence to move production there.

The Impact of Lower Wages on Manufacturing

China’s most obvious advantage is the size of its workforce. The country’s seventh national census counted about 1.41 billion people. In basic supply-and-demand terms, when the number of people available for low-wage factory work is large relative to the jobs on offer, wages stay low.

Migration amplified this effect. Until the late 20th century, most Chinese people lived in rural areas and were poor or lower-middle-class. As reform opened industrial jobs in coastal cities, tens of millions moved from farms to factories, reversing the country’s rural-urban balance. Many of these migrant workers were willing to take long shifts at low pay because factory wages still beat farm income.

A large labor pool does more than lower the hourly cost of work. It lets factories:

• produce in very high volumes,
• add workers for seasonal peaks such as the run-up to holiday shopping in Western markets, and
• respond quickly when a customer’s orders suddenly jump.

Labor rules also played a role. China historically had weak enforcement against child labor and lower minimum wages than more industrialized countries. That has been changing. China sets two minimum wages, an hourly rate and a monthly rate, and the monthly figure excludes extra pay for overtime, night shifts and weekend work. Provincial governments set both and update them every few years, often in response to a rising cost of living. As of 2025, Shanghai had the highest monthly minimum wage among the 31 province-level governments, at RMB 2,690, and Beijing had the highest hourly minimum, at RMB 26.4.

Rising wages are one reason some low-skill assembly has moved to countries such as Vietnam and India. For many manufacturers, wages are no longer China’s main draw.

China’s Business Ecosystem Advantage

Factories do not work in isolation. Making a product depends on a network of raw material suppliers, component makers, assemblers, logistics firms, government agencies and customers, all competing and cooperating at once. China’s version of this network has grown enormously since the 1990s.

Shenzhen is the standard example. It developed into a center for the electronics industry, with component manufacturers, assembly contractors, low-cost production workers and a technical workforce all concentrated in one region. A company designing a new device can find suppliers for screens, circuit boards, casings and cables nearby, and can get prototypes and design changes turned around quickly.

Apple is the best-known company to rely on this kind of cluster. Its contract manufacturer Foxconn, a Taiwan-based electronics group, assembles products in China with many component suppliers located close to its plants. Keeping the supply chain in one place keeps costs low and margins high. Shipping all those components to the United States for final assembly would add transport costs, delays and inventory risk, which makes it uneconomical for many products.

This is the advantage that is hardest to replicate. A country can offer lower wages than China today, but it cannot quickly build thousands of specialized suppliers, experienced engineers and the transport links that connect them. An efficient supply chain can outweigh a higher wage bill, which is why China kept its position as labor costs rose. Under the logic of absolute and comparative advantage, a country can stay competitive in a product even when another has cheaper inputs.

China’s Regulatory Environment

Manufacturers in most industrial economies must comply with extensive rules on consumer protection, workplace safety, labor rights and environmental protection. Compliance costs money: inspections, safety equipment, insurance, pollution controls and legal staff.

As a relative newcomer to the global industrial economy, China historically imposed fewer of these costs. Chinese factories have in the past used child labor, run long shifts and failed to provide workers with compensation insurance. The government has since introduced reforms meant to protect workers’ rights and improve pay, but compliance has been uneven across industries and change has been slow.

Environmental rules followed a similar pattern. Weak enforcement allowed factories to spend less on waste management and emissions controls. The cost showed up in air quality: a 2019 World Bank report found that 18 of the world’s 20 most polluted cities were in China. Air pollution in the largest Chinese cities fell during the early COVID-19 shutdowns, a sign of how much of it came from industrial and transport activity.

How Taxes and Duties Benefit Chinese Manufacturing

Tax policy was designed to support exports. In 1985 China introduced an export tax rebate policy to end double taxation on exported goods. Under this approach, exports are effectively zero-rated for value-added tax (VAT): either they are exempt, or the VAT paid on inputs is refunded when the goods leave the country.

An example shows why this matters. Suppose a factory’s inputs carry VAT, and that tax would normally be built into the price of the finished product. If the product is sold abroad and the importing country also charges its own sales tax or VAT, the buyer pays tax twice. Rebating China’s VAT on exports removes the first layer, so the product enters foreign markets at a lower pre-tax price. The rebate rates have been adjusted over the years, which lets the government favor some industries over others.

China and U.S. Tariffs

The trade advantage has drawn a policy response from the United States. In July 2018, during Donald Trump’s first term, the U.S. imposed China-specific tariffs on 818 imported products valued at $34 billion. That began a series of escalating rounds. By February 2020, U.S. tariffs applied to $550 billion of Chinese goods, and Chinese tariffs applied to $185 billion of U.S. goods.

After Joe Biden took office in 2021, China’s foreign minister, Wang Yi, called for the tariffs to be lifted. As inflation rose in 2022, Biden and then-Treasury Secretary Janet Yellen said lowering some China tariffs could ease price pressure at home. The administration went the other way: in 2024 it raised tariffs on certain Chinese products, including some solar energy components. Trade policy toward China remained a live issue after Trump returned to office in January 2025.

Tariffs raise the cost of Chinese goods in the U.S. market, but they do not remove the underlying supply chain advantage. Some companies have responded by shifting final assembly to other countries while still sourcing many components from China.

Impact of Currency on Manufacturing Economy

The exchange rate is the last major piece. China has long been accused of keeping the yuan artificially weak to give its exports a price edge over competing goods made in the United States and elsewhere. The mechanism is straightforward: China’s central bank limits the yuan’s appreciation by buying dollars and selling yuan. A cheaper yuan means foreign buyers need fewer dollars to pay for Chinese goods, which makes those goods more competitive internationally.

The yuan’s path shows how this has played out:

• In late 2005, the yuan was estimated to be about 30% undervalued against the dollar.
• In 2017, it rose about 8% against the dollar, a move analysts linked to Trump’s threat to label China a currency manipulator.
• From June 2018, when U.S. tariffs took effect, the trend reversed and the yuan weakened.
• On Aug. 8, 2019, China’s central bank set the yuan at 7.0205 per dollar, its weakest level since April 2008.
• The yuan continued to lose ground during and after the pandemic. It averaged 6.4529 per dollar in 2021 and reached 7.25 in July 2024.

Buying dollars to hold the yuan down leaves a country with large foreign currency holdings: China’s foreign exchange reserves totaled about $3.2 trillion as of December 2024. A weaker currency also has costs at home, since imported goods and raw materials become more expensive for Chinese consumers and firms.

Can Other Countries Replace China?

Some production has moved, particularly labor-intensive assembly. But a competitor would need more than cheap labor: comparable supplier clusters, skilled technical workers, infrastructure and the policy support China built over four decades. That is why many companies diversify by adding factories elsewhere rather than leaving China entirely.

The Bottom Line

Companies weighing where to manufacture, and anyone tracking global trade, should look past wage rates when judging China's position. Its supplier clusters, skilled workers and infrastructure took four decades to build, and tariffs and rising pay have not removed that edge. Many firms are adding factories in countries such as Vietnam and India while still sourcing components from China, rather than leaving entirely.
