Selective Migration, Human Capital Deepening Of China's Agricultural Development

China is the biggest developing country in the world. And it is a large agricultural nation in which agriculture play an important role. At present, our agriculture has entered a new stage of development. The new stage have new features. We should consider the new problem of china's agriculture from a new point of view. Can we truly make advice for China's agricultural development.The labor-surplus dual economic structure is the main characteristic of our country economic system. The surplus labor transfer from agricultural department to industry department is the core progress of the dual economic structure transforms. The Lewis-Fei-Ranis Model can be chosed to analyze the prolem of developing country's rural surplus labor transfer. But in recent years, due to the return on education is gradually increasing in the process of industrialization and urbanization, the non-agricultural transfer of labor force show the characteristics of selectivity, the labor force who has the higher level of education is prior to finish the non-agricultural transfer. This kind of phenomenon requires us to learn from the Lewis-Fei-Ranis Model, at the same time, supply and improve it according to China's actual situation. In the existing literature in which the accumulation rate of human capital be regarded as exogenous variable, labor force transfer will inevitably lead to the loss of human capital. The decreasing of human capital in rural areas is caused by the non-agricultural transfer of labor force who has the higher level of education. After the human capital introduced into the Lewis-Fei-Ranis Model, the above phenomenon will lead to the postponed coming of turning point of the shortage point and the commercial point coincidence. Moreover, besides those conditons introduced by the Lewis-Fei-Ranis Model, a successful development of dual economy also depends on conditon that the ratio of net growth of the agricultural worker's average labor capital be more than zero. This is complement for the Lewis-Fei-Ranis Model according to China's actual situation.In deed, selecive transfer to a large extent determines the investmment decisions of the rural households. If the accumulation rate of human capital be regarded as endogenous variables rather than exogenous factor, then selecive transfer improve the demand for the investment of human capital drived by the motive of arbitrage in the cross-sectoral, but also it is in favor of raising the ability of investment for people's quality, which may accur the result of human capital deepening in rural areas.In this paper, we amend the Lewis-Fei-Ranis Model of agricultural development, and induced human capital into the process of labor force transfer. Based on Schulz's transfermation of tradition agricultural theory and the new economic growth theory included human capital, this paper analyzes the agricultural development mechanism of huamn capital innovation and the way it play the roal. And learn from the analyzing method made by Kanbu and Rapoport, we make the model of the accumulation of human capital in rural under selective transfer, establishing the relationship of labor force trabsfer,human capital level and China's agricultural development. The analyzing for the times series of China's selective transfer of rural labor force,the deepening of human capital and agricultural development from reform and open policy carried out to a large extend support the conclusion in this paper. Finally, a conclusion is drawn that, under the condition of selective transfer, the human capital in agricultural and rural areas that brought by labor force non-agricultural transfer will be foundamental power to drive agricultural development.Author proposes related policy suggestion as follows: firstly, through setting up a public information network to provide the effective leading of information for farmer's transfer, through reforming the residence registration system and land system to eliminate the barriers of labor force tranfer; Secondly, through reforming education system,simulating personal investment of human capital,increasing government financial investment for education in rural areas to raise the level of human capital; Thirdly, based on promoting labor force transfer and raising the level of human capital, promote agricultural high-tech popularization and application, speed up development and transformation of rural achievements in science and technology, develop the "three high" agriculture which main products are labor-intensive products, promote industrialization of agriculture to ensure that China's transformation from traditional agriculture to modern agriculture can be achieved smoothly.
