Research On Agricultural Technological Zone Distribution Based On The Theory Of Growth Pole

Judging from the current status of China's agriculture, domestic agricultural products are facing impacts and challenges from both inner and abroad market. As an effective carrier of agricultural industrialization, agricultural zone plays a function of innovation and industrial organization. Therefore, the strategic adjustment of agricultural industry and the development agricultural technological zone are the fundamental modes to meet the challenges. The construction and the development of agricultural zone have become an effective way and a breakthrough of agricultural structure adjustment and eliminating poverty, which has promoted the upgrade of local agricultural industry, accelerated the comprehensive development of the rural economy and played a significant leading role in promotion agricultural technology, agricultural industrialization and the development of rural industrialization.It is a wise selection to develop agricultural technological zone, promote regional economic restructuring, popularize advanced agricultural technology, and take the road of regional development according to the natural resources and the basic conditions of local areas. The leading role of the agricultural zone depends on the function of its model and radiation. Therefore, it is of great practical significance and historical value for the promotion of the industrialization of agriculture and rural economic development, and realizing agricultural production scale, specialization and the modernization of agriculture to study industrial distribution theory, to optimize the layout of agricultural zones, to make full use of the gathering and the proliferating effect of agricultural technological zones and to probe into the related problems in depth.The article sets off from the history evolution of the agricultural Science and Technology Parks, and comes the conclusion that that the agriculture Science and Technology Parks can be promoted in rural area and drive the development of economy in rural area as the growth pole by means of analyzing its concept, characteristic and function. Based on the conclusion, the article analyzes how the growth pole and growth center affect the polarization effect and diffusion effect to the surrounding regions and discusses the factor to affect diffusion effect by applying the theory of growth pole and recursion theory. Borrowing the their predecessors findings, the article shows the model designed to demonstrate the diffusion effect of agricultural Science and Technology Parks and offers the theory of defining the zero edge of the diffusion effect. The article puts forward the principles of overall arrangement of agricultural Science and Technology Parks and takes Shandong province as the example to demonstrate the new ideas to develop the rural economical network.The purpose of the thesis is to explain the benign interaction relations, which among the key area of agricultural science and technology zone, the model district and the radiation zone; and research the method and the influence factors of configuring the space distance among the agricultural science and technology zones, which use the agricultural region development theory, agricultural location theory, the theory of systems engineering and the theory of industrial colony etc., based on the highly effective system function, market adaptability, highly effective technical innovation, management mechanism and the good economic efficiency of agricultural science and technology zone, according to the estimated model of diffusion effect and the estimated model of gathering effect, and with the help of the increase extreme theory of region development theory. The paper provides the theoretical basis for choosing reasonable space distance, playing the diffusion effect of the agricultural science and technology zone farthest, realizing the industrialization, scale and specialization of agriculture, which are for configuring national, provincial and county agricultural science and technology zones properly, and promoting all-round development of rural economy.
