Optimal allocation of physical capital and human capital in three sectors is derived, the fraction of physical and human capital in each sector is positively related. The balanced values and the growth rates at steady state are given under certain conditions. Finally relations between the fractions of human capital and parameters are analyzed elaborately.展开更多

Hubei Province as a large agricultural province is significantly affected by the human capital. The paper selects the correlation data about rural economic growth in Hubei Province as samples to analyze the contribution of physical capital and human capital to rural economic growth by the new C-D function and SPSS22. 0. The results show that the effect of the elasticity of human capital is greater than that of physical capital in rural economic development; the high quality rural human capital storage and the average years of schooling of rural labor force will increase the net income of rural household. Therefore,we should not only increase input of physical capital but also increase the input of human capital to raise the level of human capital in rural areas and promote sustainable development of rural economy.展开更多

The authors also have applied an adjusted Hausman model to measure the structure of exported technology at China＇s provincial level regions. Upon this foundation, approaching the subject from its domestic and international impact factors, this paper empirically tests the motives driving the structural transformation of China＇s technology export. The conclusions are： （1） the structure of China＇s technology export has improved significantly in recent years, but not as highly as measured by Rodrik （2006） et al. （2） The dynamic mechanism of the structure of China＇s technology export differs from that of the other developing countries. At national and regional levels, the mounting physical capital stock is the fundamental driving force, but with obvious decreasing marginal utility. （3） Excessive unskilled labor in the capital production sector in the central and western regions, and excessively low export prices in the eastern regions have caused negative effects of the skilled labor in the western region and unskilled labor in the eastern region on local structure of technology export.展开更多

A two-dimensional stochastic differential system is deduced by Ito＇s formula, by using Lyapunov function methods, whether the growth rates of physical capital and human capital are exponentially stable or unstable depends on the values for parameters. Finally, we also illustrate the results with two examples.展开更多

文摘The paper develops an endogenous economic growth model about allcation of physical and human capital in three sectors. Optimal allocation of physical capital and human capital in three sectors is derived, the fraction of physical and human capital in each sector is positively related. The balanced values and the growth rates at steady state are given under certain conditions. Finally relations between the fractions of human capital and parameters are analyzed elaborately.
文摘Human capital is becoming a major driving force of promoting economic growth and social development. Hubei Province as a large agricultural province is significantly affected by the human capital. The paper selects the correlation data about rural economic growth in Hubei Province as samples to analyze the contribution of physical capital and human capital to rural economic growth by the new C-D function and SPSS22. 0. The results show that the effect of the elasticity of human capital is greater than that of physical capital in rural economic development; the high quality rural human capital storage and the average years of schooling of rural labor force will increase the net income of rural household.
