中文不容易区分,英文讲出来比较明白
1 资本在产出中的份额就是share of capital, which is the exponent of capital (alpha) in Cobb Douglas production function
2 资本产出比率是capital output ratio, which is K/Y K是经济中的总资本存量,y是总产出,宏观经济学做calibration需要这个指标作为target ratio
3 资本的边际产量就是marginal product of capital, which is dF/dK, given F(K,L)=K^(alpha)*L^(1-alpha)
