Based On The Symbiosis Theory Of Agricultural Industrial Chain Stability Study

As a mid-stage industrized country, China’s industry development can not leave with the support of agriculture,since agriculture is closely related with the healthy and stable development of national economy and society. Although China is a country with large agricultural areas, the level of China’s agricultural industry is still very low, compared with that of developed countries. There is a basic view in the paper:the key to promote the health development of China’s agricultural industry is improving the stability of agricultural industry chain.In the operation of the industrialization of agriculture, as a major form that connects small farmer and large market, agricultural industrial chain has been widespread concerned by the theoretical community.The core issue of agricultural industrial chain is to study its stability, that is, to analyze and explore the internal economic relations, operation mechanism of agricultural industrial chain under the premise of the unity of economic, social and environmental benefits,and to achieve the ultimate goal of its healthy and efficient operation. As the core one of the theories of population ecology, symbiotic theory is used to research material exchange, information transfer,energy transfer between complex populations, co-symbiosis models and the environment, so it has good compatibility and suitability with the problems about agricultural industrial chain.Symbiosis is a very common phenomenon both in the nature and human world. We can say,its main issue is cooperation.In the operation of agricultural industry chain,there is a similar biology dependent chain,the leading enterprise and upper stream farmer household farmer get closely together and have the same destiny.The symbiosis relation between enterprise and farmer household is substantially a strategy cooperation and collaboration relation which is established on respectively core specialty based on the supply and the demand.So, using symbiotic theory to investigate the stabilization of agricultural industry chain will have much important instructive significance. The paper bases experts interviews,absorbs the latest theoretical results by docmentary analysis,adopts the ecological and economic methods, such as Symbiotic theory, Multiple shareholders theory,Logistic growth model,Shapley value in n-person cooperative game,to demonstrate the static and dynamic stability of symbiotic system of agricultural industry chain,tries to build the stability evaluation system of agricultural industry chain and study a specific case, using the analytic hierarchy process and Delphi appraisal methods.The article finally puts forwards a series of measures from the point of three elements of symbiotic on how to improve the stability of agricultural industry chain. The paper systematically and deep researches the stability of symbiotic system of agricultural industry chain, for the sake of providing theoretical guidance for members to reasonably select symbiotic models and increase co-benefits,and also supplying planners and policy makers of agricultral industry with useful references.Through the symbiotic system stability analysis of agricultural industrial chain,the paper points out the main reasons of the instability of agricultral industry chain are the lack of symbiotic and honesty concepts of economic entities,opportunism behaiviors and so on,which lead to the discord of symbiotic relationships and cause the damage to the stable operation of agricultural industrial chain.From the perspective of symbiotic theory,the paper initially attempts to establish the stability evaluation system of agricultural industrial chain. It divides the symbiotic system of agricultural industrial chain into two subsystems:the stakeholders’satisfaction and symbiotic environment, where5main indicators and25elements are listed and the AHP-Fuzzy evaluation method is used.So,it is an innovative attempt. The paper reaches the following conclusions:first, the value-added ability of industrial chain is the core of the stability of the agricultural industrial chain;second, the stability of agricultural industrial chain can be achieved under the premise of the improvement of the interest-connected mechanism;third, tactive assistances and promotions from the government is the basic power of the stability of agricultural industrial chain;fouth, stengthening the index evaluation system establishment is helpful to improve agricultural industrial chain’s health development.
