Research On System Dynamics Modeling And Policy Simulation Of "Internet+" Mobile Phone Recycling Mode

“Internet+recycling” is a reform of the traditional recycling mode,which integrates Internet thinking,technology and mode into the recycling industry chain to realize the transformation and upgrading of the traditional recycling mode.The “Internet+” mobile phone recycling mode makes it possible to recycle obsolete mobile phones in a convenient,efficient,standardized and safe way.However,as an excellent e-commerce mode,its operation performance is not ideal.In the face of increasing demand for recycling and poor performance of recycling situation.It is crucial to explore the influence mechanism,reveal the reason of poor performance and design a reasonable recycling incentive policy.“Internet+” mobile phone recycling mode is a comprehensive recycling system with multiple recycling subjects,recycling links and influencing factors.Considering the interconnectedness of the recycling system,this thesis built a theoretical model of the interaction between each recycling body and the influencing factors through system dynamics method.Based on the theoretical model,the important links and key factors that influence the operation performance of recycling mode were identified.Accordingly,the system dynamics model of recycling policy was built to simulate the recycling performance of heterogeneous subsidy policy and subsidy method.The specific research contents of this thesis are as follows:(1)The evolution of “Internet+” mobile phone recycling mode was summarized based on the bibliometrics method,and the research trends and hot spots in the field of mobile phone recycling were analyzed visually from two dimensions of time and space.Through the comparative analysis of different types of recycling modes,the mainstream status of the third-party recycling mode under the “Internet+recycling” mode was established.Through comparative analysis of different types of recycling modes,the mainstream status of the third-party recycling platform under the “Internet + recycling” mode is established.The factors influencing the recycling pattern are identified and classified from two aspects: exogenous and endogenous.(2)In order to explore the mechanism affecting the operation performance of recycling mode,this thesis specifically analyzes the interaction between material flow,information flow and capital flow with the recycling subject as the classification standard,and expounded the functional structure and operation mechanism of recycling mode on this basis.Accordingly,the influencing factors of each link were summarized based on the four links,including supply,collection,recycling and sales,and a system of influencing factors covering the whole recycling process was established.(3)The system dynamics theory and modeling method were introduced to build the recycling system model that included the external operation environment and internal operation process of the recycling mode.By exploring the operation mechanism and feedback law of the recycling mode,the influence and effect of each link and its factors were clarified.The results show that supply and collection links play significant role in operating performance and recycling and sales links have a delayed response.Consumers' perceived risk,perceived benefits and platform's service quality are dominant factors for the improvement of recycling performance.The poor economic benefits of recycler and the inactivity of second-hand platform are the main restricting factors.(4)In order to balance the relationship between the expenditure of government subsidy and the performance of recycling mode and accelerate the development of recycling industry,this thesis built a recycling policy system dynamics model containing multi-subsidy types.The operation performance of recycling mode was taken as the evaluation standard,and the situation of heterogeneous subsidy policy and subsidy mode was simulated to determine the optimal incentive policy.
