In empirical structure stock as capital data, creates a translog production function research, the paper uses the perpetual and estimates human capital as labor infrastructure is insufficient or surplus.

So we can explore the stock of China＇ s marginal product of China＇ s infrastructure capital is always greater than the marginal product of private capital.
