GDP growth rate=3 times TFP. This equation was derived from an economic model.
Annual TFP of Chinese economy in the last thirty years was 3%. By the equation, GDP annual growth rate should be 9%. The four asian tigers had TFP 2.5% and the growth rate should be 7.5%. USA had 1% growth rate in TFP last thirty yrs and its GDP growth rate was about 3% annually. If you knew other economies this equation applies, please post here.
