| The 21st century is a knowledge based economy society, Knowledge based economy is the economy based on knowledge and technology as the core, human capital as the engine, its growth way is such a economic growth which take the sustainable scientific development concept as the theme.Human capital investment has been considered as a investment which have the best benefits and the highest return on. As China's underdeveloped west, to change the face of relatively backward, it must clear that the role of human capital in economic growth. Therefore, by analyzing the present situation of local human capital stock, estimates the output contribution of human capital to economic growth, and further calculate the optimal proportion of investment in human capital, this is not only have practical guard in optimizing the structure of human capital investment, but also have practical significance in promote regional harmonious development of the economy.In this paper, take Sichuan province as an example,which is important in economic development in western China, and take human capital theory, new economic growth theory as guide,first of all, by the method of combining literature research and analysis of statistical data describing, to analyze the overall economic development in Sichuan and Sichuan human capital accumulation process; On this basis, calculate the primary, medium and higher levels of human capital stock in Sichuan. Secondly, take Lucas expansion model and dynamic economic system optimal control models as the economic analysis method, quantitative analyze the contribution rate of economic growth in Sichuan in different academic levels of accumulation of human capital stock; thirdly, by analyzing the difference of the output contribution in different levels of human capital, through the optimization of dynamic control model, build Hamilton function, calculate the optimal proportion of investment in human capital of feedback at the economic growth. Finally, provide the corresponding policy recommendations for selecting optimal route of reality economic development in Sichuan.By analysis, we got the following conclusions:(1)Through the Lucas extended production function model, this article analyzed human capital's contribution on all levels to economic growth between 1996-2007 in Sichuan Province. The contribution of primary,medium and higher stock of human capital to economic growth in Sichuan were-0.23,0.15,0.0587; through dynamic optimal control model, this article constructed Hamilton function and calculated optimal economic growth's investment ratio of physical capital stock, medium and higher stock of human capital in Sichuan were 0.51,1.27,5.12.(2) The labor factor's inputs on the marginal contribution to the economic growth of Sichuan was the largest, abundant labor resource was the main source of economic growth of Sichuan, labor-intensive growth is the main mode of economic growth of Sichuan; while the effective utilization of physical capital stock was low, unbalanced property invest proportion restricted the physical capital pull to economic growth.(3) View from all levels of human capital stock, the stock of human capital at all levels in Sichuan was volatile, the overall human capital stock increased slowly. Primary human capital stock declined every year, while medium and higher stock of human capital increased year by year. Higher human capital stock has the fastest-growing, However, the primary and medium stock of human capital has a big base quota, which has a major impact to overall human capital stock alteration.(4) Analysis of the optimal investment ratio of all factors of production, at the current economic growth of Sichuan, the economic role of fixed investment in physical capital stock hadn't give full play; investment structure of primary stock of human capital was irrational, which restricted the optimizing economic development; and there was a shortage of investment in medium and higher education, medium and higher human capital efficiency has yet to be a comprehensive upgrade.Therefore, adjusting the industrial structure in Sichuan and optimizing human capital investment ratio will be the preferred path to promote a harmonious and sustainable economic development... |
