A basic about the onging trade war. How to estimate currency exchange rate?
There are many methods to estimate currency exchange rate. Here I propose a simple way to do this job by using annual electricity production per capita (AEPPC). For example, the US AEPPC was 12000 kwh in 2017, whereas China counterpart was 4600 kwh. In other words, the US is 2.6 times higher than China. Given the physical law is universally correct regardless where it operates. If so, one US dollar must be equal to 2.6 China Yuan. Therefore, China GDP was much underestimated, simply because the value of China Yuan (or RMB) was not correctly praised. China GDP 2017 must be US$33 trillions (=86/2.6); China GDP per capita should be $23571 last year, much higher than the officially announced figure (~$9200).
If this is correct, that would well explain: 1) people in China appear to have much better living standard than those with GDP per capita of $9200; 2) China government has solid basis to deal with the ongoing trade war initiated by the US President Donald Trump; and 3) China has a very slim chance to loose this trade dispute with the States.
