出口補貼萬億美元怎麽算出來的？問了一下GROK給的2024是一千億，以VAT rebate為主，占出口總額的3%左右

Estimated Range for 2024:

Based on available data:

•  Direct subsidies to listed companies likely exceeded $40 billion USD in 2024, extrapolating from the 2022 figure of $37 billion and the 27.3% growth trend.

•  EV trade-in subsidies alone supported 6.6 million vehicles at up to $2,800 each, implying at least $18.5 billion for this program.

•  Tax rebates, interest assistance, and other indirect subsidies (e.g., 3% of industrial firm revenues) could push the total export subsidy value into the tens of billions annually, though no precise figure is confirmed.
