请问这道题答案解析标红的地方怎么理解,1,为什么会有这个公式TFP = Labor productivity growth − Growth in capital deepening,怎么理解这个公式,再课上没有提到过 2,从A的解释,A is incorrect because once the economy reaches steady state growth, capital deepening cannot be a source of sustained growth in the economy. 是否可以理解判断reaches steady state growth点就是growth of capital ddeeping=0?
