China GDP as % of US (nominal)

## What this measures

This measures the size of China's economy relative to the United States economy in nominal dollar terms, expressed as a percentage. The ratio is calculated annually using current exchange rates.

## Background

China's nominal GDP as a percentage of US nominal GDP, annual.

China's figure divided by the US figure for the same year, × 100, from World Bank series synced by /api/cron/worldbank-sync. 100 = parity. Nominal dollars move with the exchange rate: a weaker yuan lowers the ratio even if output does not change.

## Why it matters

The relative scale of the two largest economies shapes supply-chain decisions, market-entry strategies and policy risk assessments. A rising ratio signals China's growing weight in global demand, production and finance, which affects procurement costs, customer bases and regulatory reach for organizations operating across borders.

## How to read it

A rising percentage means China's economy is growing faster than the US economy in dollar terms, or that the yuan is strengthening. A value of 100 would represent parity; values below 100 indicate China's economy remains smaller. Because the measure uses nominal dollars, currency movements can shift the ratio even when real output is unchanged.

## What it does not say

The ratio does not reflect purchasing power, real output growth or per-capita income. It does not indicate which economy is gaining competitive advantage in specific industries or technologies.
