China’s Rising GDP Share Signals a Shift in Global Economic Power

• China’s hold on the global economy is nearly six times larger than it was in the mid-1980s.
• In 2025, China’s economy grew roughly 5%, hitting a new high of about $20 trillion.
• China is expected to be responsible for about 26.6% of all global economic growth in 2026.

China’s share of the global economy (measured by its proportion of worldwide GDP) has risen to an estimated 19.6%, according to the most recent data. This brings the country close to representing nearly one-fifth of the total global economic output.

In the mid-1980s, China’s share was only about 2.9%, meaning its slice of the world economy is now over six times larger, marking a huge jump from four decades ago.

Economists measure this using the nominal GDP or purchasing power parity (PPP) metrics, both of which show that China has become a dominant global economic force, second only to the US.

There are several factors that contributed to China’s growth. Some of these include:

• Becoming a massive factory for the world through exports
• Building vast manufacturing and supply networks
• Large population and urbanization
• Strategic investments in infrastructure and technology

In 2025, China’s economy grew about 5%, hitting a new high of about ¥140 trillion ($20 trillion). It also remained a top exporter of green technology, with electric vehicle exports hitting a new record last year.

BRICS on the Rise

China’s growth is part of a greater, ongoing change where more of the world’s economic activity is moving to developing countries, especially in Asia. Groups like BRICS now make up a massive part (around 40%) of the global GDP in PPP terms, with China being the biggest member.

Additionally, emerging economies, led by China and India, are responsible for more and more of the world’s growth and production.

This shift is reducing the historical economic leadership of wealthy Western nations such as the G7, as other parts of the world are growing more quickly.

China’s having nearly 20% of global GDP doesn’t signify it has overtaken the United States in nominal output, where the US retains its lead. However, it does show China’s economic power is rising fast, particularly when adjusted for purchasing power.

Now, it’s expected for China to be responsible for about 26.6% of all global economic growth in 2026. This could make China the main engine for the world economy, particularly when many wealthy countries are growing slowly or struggling with aging populations.
