According to the GDP data of major global economies in 2022, the United States still ranks first in the world. Last year, its GDP reached $25.47 trillion, accounting for about a quarter of the global economy, and its GDP increased by $2 trillion; China ranks second in the world, with a GDP of over 18 trillion US dollars, accounting for 18% of the global market.
Japan temporarily ranks third in the world, with its GDP dropping to $4.23 trillion last year, a decrease of over $600 billion compared to 2021. Germany followed closely, with a GDP of $4.07 trillion last year. Due to slow economic growth in Japan and a significant depreciation of the yen, while Germany is still growing, it is expected that Germany's GDP may surpass Japan this year.
Among the four major economies of China, the United States, Japan, and Germany, Germany has the most balanced development, without the birth of a super metropolis or a region with a high economic proportion. On the contrary, in Japan, Tokyo is the largest city, accounting for almost a quarter of Japan's GDP. Compared to Tokyo, other cities appear much dimmer.
China and the United States are economies with many provinces (states), and the GDP of each province (state) can match the economic scale of a country. The largest economic province in China is Guangdong, with a GDP of 1.92 trillion US dollars last year, which once ranked among the top ten in the world's GDP.
The largest economic province in the United States is California, with a GDP of 3.63 trillion US dollars last year. Based on last year's average exchange rate, it is equivalent to 24.39 trillion RMB, surpassing the United Kingdom (3.06 trillion US dollars) and France (2.78 trillion US dollars), and only second to Germany (4.07 trillion US dollars). It can be called the world's largest economic province and has already surpassed the economic aggregate of most countries in the world.
