Analysis Of The Evolutionary Mechanism For Agriculture Science-Technology System And Its Positive Study

Agriculture is the base of national economy; the development of agriculture has been always paid attention to by domestic and international scholars. Improving the level of the development of agriculture is one of the key development goals in various countries and every area. It is the exclusive choice to advance the development of agriculture technology. The study of evolvement mechanism of agriculture technology system is in order to find the leading factors and the pattern of evolvement of agriculture technology system and to help the development of agriculture.This paper analyzes the effect of agriculture technology on agriculture,forestry,stockbreeding,aquiculture and studies three patterns of evolvement of agriculture in China, studying the research on agriculture technology from domestic and international scholars, there are four mechanism: the original dynamical mechanism of population,the impulse mechanism of agriculture policy,the driving mechanism of economical benefit,the following mechanism of society economy. Then, this paper analyzes the evolvement pattern of self-organization, building the evolvement model of self-organization, to analyze the factors that impelling the evolvement between sections is competition and cooperation. Thirdly, evolution equation for agriculture technology system is established relying on Haken model of self-organization theory. Through a positive analysis to the 18 city of Henan province, it is quantitatively demonstrated that the labor productivity reflecting innovation and technical progress is the ordering variable of describing agriculture technology system. And several parameters that can be controlled are given; the evolvement of system is more rational through controlling. Finally, the dissipative structure theory and gray system are applied to establish the distinguishing model. This model is applied to evaluation of agriculture technology system. And through an actual data analysis of Henan province, the conclusion is given that the evolvement of agriculture technology system of Henan is steady and rational.
