Simulation study on the coordinated development of intra-county economic industries

On the basis of the study on the overall coordinated development model of intra-county economic system, this paper establishes the model of coordinated development of industry and emulates the relationship between the change of investment level and the coordinated development of intra-county economic industries under certain parameters. The emulation result shows that in the process of investment decision making, to choose proper investment level cautiously can facilitate the coordinated development of all the industries. The result also indicates that emulating its dynamic change by the use of MATLAB/ Simulink can display visually the influence on the systematic evolution behavior caused by changing model parameters, which can provide a reference in fixing parameters of the coordinated intra-county development of overall economy and sub industries.
