Feedback complexity analysis on community health service based on system dynamic

Urban community health service (the following is short for CHS) is a complex socio-economic system, there are some negative feedback structures that limits to achieve the function of CHS, only remove the restricted factors in the structure, can lead to harmonious development between the CHS organization and community residents. Based on the system research in the concrete CHS center and CHS station, the paper analyzed the dilemma of urban CHS in Jiangxi province, built the limit-to-growth archetype of restricting to CHS development by the method of system archetype. Under the guide of systematic scientific principles, the paper established structure model by the means of the feedback complexity principle of system dynamics, and proposed the corresponding countermeasure to improve the development of CHS, which achieve the purpose of analyzing the CHS development in a system scientific method.
