Gradient Analysis Based On Field Theory In Economic Space

Economic space is human economic activities of the existing space, the diversity of economic activity to the complexity of the economic space, this also showed the in the conventional economic analysis method will not be able to grasp the development and change of the economic space. Because of the existence and development of economic space is relying on in their own geographical space, show that economic space and geographical space there is a certain item each other. Geographical space without the human economic and social activities, it is just a simple physical space, but once involving human activities, will become a man to overlap the polymerization of space. Economic space research drawn out a thought, namely to economic space research can reference geographic space and physical space of some methods to undertake, and geographic space and physical space to study the most basic of the method is the field theory. Will field theory and economic space combination of approach is called economic space field theory, this paper will build on the basis of the theory of Gansu province, economic space field a comprehensive analysis and study, thus for economic policy formulation to provide the theory basis and the value.This paper based on the above background, the first half of the paper mainly introduced the research topic, significance and articles in the research idea and method, put forward the difficulties and key, the place of innovation, and explains the paper structure framework. Second mainly introduces the economic space field theory, the production function and industry relevance theory and economic space field theory in both at home and abroad, and review the research progress of content, and the problems that exist. Half of the field theory with physics as a research tool, to Cobb-Douglas production function and column reported the input and output of the Cardiff method to improve and processing, with output function gradient model and industrial gradient field model of Gansu province three industry output efficiency and the industry in the economic space, function and the status of the dynamic change quantitative. With Surfer9.0software reuse in the form of the space trend of Gansu province14municipal three industry output value in1990,2000and2010three time interface on space shown visually, go forward hand in hand correlation analysis. The results show that:(1)in the recent20years the three industries of Gansu province the output of the gradient, the primary industry volatile, during an obvious uplift; The secondary industry small changes, has been increasing year by year, the basic present before slow, quick characteristic; The tertiary industry stable, previous have ups and downs.(2)The primary industry output distribution of Gansu province are obviously three level distribution, in Lanzhou, Tianshui and Hexi region industry developed area. The Longdong region, and is the Jiuquan are the center of the industry more developed regions. Is in the above except the less developed areas. After1990years to2000years of10years of construction, and the economic status social-fixed-asset happened obvious change, economic development more balanced distribution. The secondary industry has been the province of many departments of industry in the province is always the pillar industry. The second highest of Gansu province industrial output region for the industrial area of Lanzhou center. Next is the Longdong,Tianshui area and Jinchang area more developed. The tertiary industry has been in Gansu province of a national other provinces lagging development and slow. From2000to2010this10years the14municipal output change basic remain unchanged.(3)2007Gansu province industrial gradient field. As to the three industry production gradients in recent20years,the primary industry fluctuated and showed a obvious uplift; The secondary industry changed a little, basically increased year by year, and its’change rate got much bigger, The tertiary industry changed smoothly, but there was a fluctuation the prior period.As to the industrial correlation gradient field in2007,the status and role of the secondary industry in the economic space tended to rise, while the primary industry was relatively stable and the tertiary industry declined.Energy and raw material oriented industries within the secondary industry were still superior to others. meanwhile, the status of equipment manufacturing, electronic information industry and light industry increased, while construction industry tended to decline.Through the production function gradient influence gradient and induction gradient variations we found out the status, function, effect and changes of different industries in economic space in Gansu Province. It is helpful to provide scientific basis of industrial development policy.
