有很多方法可以评估一个经济体的实力。有一些典型的衡量标准，例如以美元、人均或购买力衡量的 GDP 规模。
但更准确地说，最好从独立性、自给自足、弹性、债务、生产和获得原材料的角度来衡量实力。还应该考虑技术。
因此，在回答您的问题时，就以美元衡量的名义规模而言，美国是最大的，就购买力而言，中国是最大的。
在独立和自给自足方面，中国击败了美国，这就是为什么中国在世界上大多数国家的出口多于进口的原因。
如果我们考虑债务，那么美国的处境要弱得多。中国的债务要小得多，而且人口众多，与美国相比，平衡起来要容易得多。
如果我们看一下生产和制造，中国击败了所有人。
美国的石油和天然气产量要高得多，这是一个优势，但中国几乎垄断了稀土。
中国经济的韧性远强于美国。在每次全球经济衰退中，中国的反弹速度都比美国快得多。
在技术方面，我真的不确定目前的平衡。中国在某些领域落后，在另一些领域领先。
There are many ways to assess the strength of an economy. There are the typical measurements such as GDP size measured in dollars, per capita or purchasing power.
But to be more precise it’s better to measure strength in terms of independence, self sufficiency, resilience, debt, production and access to raw materials. Technology should also be considered.
So in answer to your question, in terms of nominal size measured in dollars, the U.S. is the largest, in terms of purchasing power, China is the largest.
In terms of independence and self sufficiency, China beats the U.S. Hence that is why China exports more than it imports with most countries around the world.
If we consider debt, then the U.S. is in a far weaker position. China’s debt is much smaller and with such a large population, it’s far easier to balance compared to the U.S.
If we look at production and manufacturing, China beats everyone.
The US has far more production of oil and gas which is an advantage, but China holds a near monopoly on rare earths.
China’s economy is far more resilient than the U.S. At each global recession China has had a history of rebounding much faster than the U.S.
In terms of technology, I’m really not sure on the current balance. China is behind in some areas and ahead in others.
