In this paper, some important quantitative concepts of linear economic theory were calculated by using the China 1987-2002 input-output tables. First, the wage-profit curves were drawn and the relative positions of actual economic state were estimated. Second, Marxian 2-sector tables were constructed from input-output tables, and some important parameters such as organic composition of capital, rates of surplus value, rates of profits were estimated. Third, the turnpike path of the China economy was calculated by arranging 2-sector coefficient matrices in order from 1987 till 2002. It is seen that the actual growth path from 1992 till 2002 runs close to this turnpike path.
