Shu Yuan and Xu Xian-Xiang (2002) had neo-classical economic growth theory (Solow model), AK type growth model, R & D-based growth model for hypothesis testing. The result that the "Solow model does not well describe China's economic growth"; "China from 1952 to 1998 the economic growth engine is not technological progress", so the R & D-based growth model is not suitable for China; "China's production technology is AK types, changes in the savings rate has increased effect. " And that "AK type growth model to describe the 1952 to 1998, China's economic growth." On this basis, Shu-yuan, and raises the question, why is AK type growth model to describe the country between 1952 and 1998 economic growth? Shu Yuan et al (2002) that the AK type growth model with two characteristics: First, compared with the neoclassical growth model, which emphasizes non-decreasing marginal productivity of capital; the other is with the R & D compared to the type of growth model, it ignores the technical innovation and the role of engine of economic growth. Such is consistent with our view, therefore, we will not repeat a similar hypothesis tested. However, Shu-yuan, China's economic growth failed to conduct a more in-depth examination of the facts, therefore, in the establishment of AK model, the introduction of a system variable, "suitable for China's economic development path," trying to "learn by doing." point of the system variables into economic growth model. "And stressed, 'to explore the economic construction of China's national conditions for the road' is a by-product of capital." We believe that the system is not as variable as inputs into the production function. On the other hand, Shu-yuan, in the AK model hypothesis tests, "k" on behalf of the capital stock per worker, and in the establishment of economic growth model is a departure from the CD production function, the definition of a B-"for China's national conditions The economic development path "variable, AK-type production function is derived. I am Shu-yuan, according to the definition of fundamental push not the result. Therefore, we believe, Shu-yuan, the AK model is debatable.
Zhouhai Chun (1999) in the study of China's economic growth potential, the proposed conditions of unlimited labor supply, may be based on "rice field conditions" (which is my guess, the original author did not put it this way), he further assumed that the marginal productivity of labor a close to 0. And on this basis, also made a similar AK growth model. Since his aim is to study China's potential growth rate, China's economic growth and thus has not the marginal product of labor and marginal product of capital in the province. Therefore, the unlimited supply of labor this assumption may be right, but its marginal product is zero inference, the fact that the analysis is not used.
