The Research On The Information Ecosystem Of Social Security Fund

Along with rapid development of economy and society and progress of the social security, more and more public started to pay attention to information about social security fund such as policy formulation, execution, income, disbursement and so on. Though the administrations of social security fund have provided open information platforms to the public, there are still some ecological problems in information environment. So it has become an important task to construct information ecosystem of the social security fund. Under the light of the theory of information management, ecosystem and information ecology, this dissertation researches systematically the connotation, characteristic, interior mechanism, platform design and appraisal about information ecosystem of social security fund using the theoretical analysis, empirical study, quantitative analysis and qualitative analysis.1. The dissertation analyses the causes of information system ecological imbalance and the characteristics of ecological system. It redefines new definition of information ecosystem. And it points out that though it has been developed quickly, there still exist many problems such as information overloading, information pollution, information ecological imbalance and so on. It proposes the significance of constructing social security fund information ecosystem and gives definition, characteristics and connotation about information ecosystem of social security fund.2. One important task of this dissertation is to construct the model of social security fund information ecosystem. The establishment process of model is divided into two steps. Firstly the conceptual model has been established based on the analyzing of input and output, control mechanism, feedback mechanism, flow innovation and organization pattern transformation of social security fund information ecosystem. Then, dynamic model on different users transferring mutually in organizations is established using the systems dynamics method, and the conclusion is: the system can arrive at the steady state above certain control point, but the systemic stability user will tend to perish under certain control point, and has further confirmed the influence of every parameter through the system simulation.3. Platform design of social security fund information ecosystem. First the system's overall framework has been given. Next analysis and design on the system is conducted through sequence diagram and case diagram and the new system logic plan is formed. The research focuses on prediction and early warning subsystem of old-age insurance fund, risk prediction on investment profolio subsystem of social security fund and knowledge management subsystem. Finally the system implementation is introduced. 4. The dissertation established the evaluation index system from the angle of the characteristics of social security fund information ecosystem. It entrusts with the weight to all levels of targets using the analytic method of the fuzzy Borda number based on the grill separately, it applies the grey theory assessment method to give the different gray class and the whiten weight function, then it computes the grey class of appraisal coefficient and appraisal weight vector matrix, and it carries on the comprehensive evaluation to all levels of targets at last. The effectiveness of the method has been confirmed in the appraisal of social security fund at provincial level.
