Research On The Coordination Construction Of Knowledge Community Ecosystem Based On Systems Dynamics

The rapid development of Internet and information technology produces knowledge community and it has become one of the main virtual places for public knowledge exchange.The scale and knowledge volume of users are explosive,but invalid knowledge,false knowledge and inferior knowledge still exist;Knowledge community users have different knowledge levels,The media literacy of the participants needs to be strengthened;the technology and system matching the development of knowledge community still need to be improved;the development of knowledge community is not standardized,the knowledge ecosystem problems occur frequently.Therefore,based on the theory of knowledge ecology and with the goal of strengthening the collaborative construction of knowledge ecology,this paper carries out the system dynamics simulation analysis of the knowledge community ecosystem,seeks the development countermeasures to strengthen the vitality of the system,improves the participation of users,promotes the innovation of Internet knowledge,and builds a knowledge-based cyberspace.This paper uses the three elements framework of knowledge subject,object and environment,Combined with both domestic and international studies,analyzing the concept and characteristics of the knowledge community ecosystem,mining and extracting the impact elements of the knowledge community ecosystem,analyzing the performance and relationship of knowledge community ecosystem components combined with knowledge ecological chain and self-organization theory,show the knowledge subject,object and environment subsystem and the overall system operation performance.Draw the system causality diagram and flow diagram,in order to build the system dynamics model,then use Vensim Ple software for system simulation,analyze the influence of each element on the system,identify the key elements,and provide countermeasures and suggestions for the healthy development of the knowledge community ecosystem.The study shows that the overall vitality of the system shows a steady increase under the action of complex elements,improving cultural propaganda level and the participation of experts,strengthening the management requirements of the knowledge community platform can significantly enhance the system performance;improving theme media literacy,upgrading knowledge consumption,and giving full play to brand effect can provide a strong guarantee for the healthy development of knowledge communities.
