Research On Ecological System Simulation Of Agricultural Products Based On System Dynamics

With the rapid development of information society,agriculture is realizing the growth rate of the industry through the "Internet +" path,which is the important application field.Agricultural electricity is a nonlinear complex system,involving trading platform and trading main body,farmers,and many other subjects,such as level of science and technology progress,policy adjustment and industry will have an effect on electricity industry of agricultural products,to correctly grasp the development of electricity industry of agricultural products,you need the various influencing factors were systematically analyzed.In recent years,some scholars have introduced the theory of ecology into the research of the e-commerce industry of agricultural products,providing new ways of thinking,observation,research methods,theories and tools.However,the current agricultural electricity business ecosystem research is still in its infancy,there are some shortcomings: one is the agricultural electricity ecosystem study is less,especially the lack of focus on the research from the perspective of system;The second is the lack of quantitative tool examples to analyze the agricultural products e-commerce ecosystem and the agricultural products e-commerce industry management practices.These problems restrict the development of electrical business ecosystem theory and practice,in the two aspects of research to improve the agricultural electricity business ecosystem theory,auxiliary electricity theory research and e-commerce management for agricultural products is of important significance.This paper is based on "theory system-case analysis-proposed" logic,theory of business ecosystem theory,agricultural business ecosystem theory and system dynamics,from theoretic analysis and case analysis,step-by-step on agricultural products business ecosystem research.In addition,this paper uses the system dynamics as a tool to study complex problems,based on analyzing the structure of agricultural products business ecosystem and power source,construct the technological progress subsystem,marketdemand subsystem,economic development environment subsystem,industrial four subsystems,and then established the business ecosystem causal model of agricultural products.Based on this,the establishment of agricultural products business ecosystem dynamics model by using Vensim PLE software,the introduction of case study in Chongqing city of agricultural products business ecosystem,carries on the simulation analysis of the factors in the model,and with the government guidance,technical progress,the level of logistics for the simulation of different design policy variables,the government guidance,technical progress,the level of logistics has a greater positive effect on the development of the electricity supplier of agricultural products,the degree of government policy influence on the development of the electricity supplier industry of agricultural products is the most sensitive,followed by the logistics level of sensitivity,and then is the level of technological progress.Based on this,this paper puts forward countermeasures and suggestions for the development of Chongqing's agricultural product e-commerce ecosystem,and provides decision-making basis for the relevant government departments to formulate policies for the development of agricultural products e-commerce.
