Chinese Economy vs United States Economy

The US economy leads in per-capita wealth and technological innovation with a $27.3 trillion nominal GDP, while China's $17.9 trillion economy is the world's second-largest but serves a population 4.2x larger, resulting in significantly lower per-capita income ($12,720 vs $82,000). The US maintains advantages in currency reserve status, capital markets depth, and Fortune 500 companies, while China leads in manufacturing output and e-commerce penetration.
