Research On System Dynamics(SD) About Influential Factors Of Express Packing Wastes Recycling In Urban Community

The rapid development of the Internet and information technology has changed people’s lifestyles,especially consumption patterns,and the mode of receiving online shopping offline has been accepted by the masses.This has led to a sharp increase in the number of express delivery,followed by A large number of obsolete courier packaging that cannot be effectively disposed of,resulting in environmental pollution and waste of resources has become a social problem that needs urgent solution.Especially in urban communities,because the courier packaging waste recycling system has not yet been established,it has become the most concentrated place for “express waste” pollution.The harm caused by the lack of effective treatment of express garbage is not only reflected in the environment and resources,but also the unreasonable production and business model and development concept in China’s economic development.Therefore,the recycling and reuse of discarded express packages reduces the waste of resources.Purifying the environment and optimizing the development model and business structure are of great significance.However,at present,the enthusiasm of residents to participate in the recovery of express packaging waste is not high,and the action is not strong.Therefore,the study of the factors that affect the participation of urban residents in courier packaging waste recycling has a very important reference role and application value for increasing the recovery amount.Based on the research status and related theories of urban community courier packaging waste recycling,the article first reviewed the status of China’s obsolete courier packaging processing,and pointed out that there are non-standard recycling platforms,backward recycling technologies,no uniformpackaging standards,and recycling.Re-use of such issues as weak awareness,and discussed the possibility of such problems as the incomplete recycling system,lack of incentives,high recycling costs,inadequate legislation,and lack of professionals.Secondly,by combing literature and learning from previous research results,a survey questionnaire on the influencing factors of courier packaging recycling in urban community residents was compiled.Principal component analysis was used to analyze the questionnaire data,and the subjective factors and objective factors affecting residents’ participation in recycling were determined.And its weight.Based on this,a causality diagram of influencing factors of courier packaging waste recycling in urban community residents and a system dynamics model of inventory flow diagram were constructed.By changing the parameter variables,the impact of various factors on the enthusiasm of residents participating in recycling was simulated.Finally,according to the simulation results of the single strategy and the mixed strategy,solutions and suggestions are given to the urban community to improve the recovery of express packaging waste.This paper builds the causality diagram of the influencing factors of urban community express packaging waste recycling and the system dynamics model of the inventory flow diagram and the simulation study of the model.The main conclusions are as follows:(1)To increase the recovery of urban community express packaging waste For the purpose,it is very necessary to study the factors that affect the residents’ participation in recycling;(2)At present,there are mainly three types of disposal methods for abandoned courier packages in urban communities: as garbage disposal,landfill incineration,waste collection station recycling,and enterprise recycling;(3)Factors influencing residents’ participation in recycling are subjective and objective factors,among which economic incentives and recovery channels are the most important subjective and objective factors;(4)only one certain influencing factor will be promotedand multiple influencing factors will be enhanced simultaneously.There are different degrees of influence on the enthusiasm of residents to participate in recycling;(5)Accelerate the speed of recycling of urban community express packaging waste requires the government,the urban community,enterprises and residents to jointly complete.The possible innovations of this paper are: First,the research and development of express packaging and recycling of waste is different from the previous studies of waste packaging,used electronic products,and household waste,etc.Second,the participation of urban community residents in courier packaging The influencing factors of waste recycling are research contents,and the research perspective is also different from most of the previous studies focusing on colleges and universities to study the status,causes,and solutions of recycling.Third,the research method involves questionnaire survey and principal component analysis.Combining with system dynamics,the quantitative dynamic method simulation simulation is different from previous qualitative theoretical analysis to provide more reliable and operable measures and suggestions for the recovery of express packaging waste.The limitations of this paper: First,the selection of influencing factors is relatively limited.Only24 factors that are more important have been selected through investigation and reference of related data.A model that reflects the real situation as much as possible has been established.Second,the data collection volume in the middle and high age groups.Relatively insufficient,limited by time and ability,the amount of information collected in 51-60-year-old and 61-year-old or older is relatively insufficient in this study.Although the selected sample has a certain degree of representation,the number is far less than the actual number.
