Is China’s economic income mainly from foreign trade or national tax?

Is the backbone of China’s economy state-owned income or foreign trade import and export? Some people say that the country now mainly relies on foreign trade for import and export, and state-owned taxation is simply not relevant. Please explain what the concept is. Thanks!

National tax, that is, national tax, is the main source of national fiscal revenue. The sources of national taxation include taxes on foreign trade and taxes on domestic production and trade.

With our country’s years of reform and opening up, foreign trade has become an important part of the national economy. Despite this, domestic trade still accounts for a larger proportion.

Foreign trade and domestic trade are the two wheels of our country’s national economy, and both are indispensable. If someone thinks that domestic trade is insignificant, it would be inappropriate.
