Background

In today's society, with the sustainable development of economy, material products are rich and diverse. The production speed of products has far exceeded people's needs. Emission reduction and environmental protection have become people's new pursuit. Closed loop supply chain should consider not only product life cycle and recycling, but also economic and environmental benefits. It has become the focus of scholars all over the world. Closed loop supply chain refers to the complete supply chain cycle from procurement to final sales, including product recovery and reverse logistics supported by life cycle. It is a highly complex process. In the closed-loop supply chain, the simplest form is composed of manufacturers, retailers and recyclers. Recycler is the most critical link in the new closed-loop supply chain system, which is not available in the traditional supply chain. Therefore, this paper mainly studies the change of recyclers when exogenous variables fluctuate from the perspective of economic psychology.

Research Objects and Methods

Most scholars use short-term static methods when studying the uncertainty of recyclers in closed-loop supply chain. It is particularly important to analyze the uncertain factors in the closed-loop supply chain. In order to analyze this problem, this paper first improves the closed-loop supply chain model of capital flow and logistics coupling, so as to better simulate the real closed-loop supply chain. Secondly, the sensitivity analysis function of Vensim software is used to simulate the impact of exogenous variables on the inventory value and capital value of recyclers in the closed-loop supply chain model. At the same time, in order to verify the impact of recyclers' emotional stability, this study adopts the following scale. The communication anxiety scale adopts 15 questions of the Interaction Anxiety Scale (IAS) compiled by Leary, with a single dimension and a 5-level score, from 1 to 5 to “very inconsistent”. The higher the score, the greater the degree of social anxiety. The emotion regulation self-efficacy scale adopts the emotion regulation self-efficacy scale (RES) revised by Caprara. The 12 questions are divided into three dimensions: expressing positive emotions, managing depression / pain and self-efficacy of managing anger / anger, with 4 questions in each dimension. A 5-level score is adopted, from 1 to 5, which means “very inconsistent” to “very consistent”. The higher the score, the higher the degree of self-confidence in regulating their emotions. In the study, Cronbach's α The coefficient is 0.80. The aggression scale adopts the aggression scale (bpaq) compiled by Buss and Perry

The scale has 29 questions and is divided into four dimensions: physical aggression, verbal aggression, anger and hostility. The higher the score, the stronger the attack. In this study, Cronbach's α The coefficient is 0.85. The depression questionnaire adopts Beck's revised depression Inventory-II (BDI-II). The questionnaire has 21 questions, with a single dimension. The higher the total score, the heavier the degree of depression. The data were obtained by spss19 0 and amos17 0 for analysis.

Results

the 19 exogenous variables were divided into four categories: Manufacturer related parameters, retailer related parameters, recycler related parameters and other related parameters. The sensitivity of these 19 parameters to recycler inventory and capital in closed-loop supply chain is simulated and analyzed. Through the comparative analysis of sensitivity chart, it can be seen that the manufacturer's inventory adjustment time, the retailer's safety inventory coefficient, the retailer's smoothing time, the retailer's inventory adjustment time, the collector's fixed expenditure and the collector's initial inventory value are positively correlated. And have a significant impact on collectors' inventory and emotional stability. The reason is that appropriate time adjustment helps to reduce work pressure and naturally improve job satisfaction.

Conclusion

in the closed-loop supply chain, the fluctuation of the same exogenous variable in the same range has a more significant impact on the recycler's inventory than on the recycler's capital. For recyclers, the decline of inventory value has a positive impact on the capital of recyclers, while the decline of capital value has a negative impact on the capital of recyclers. The impact of retailer order smoothing time on recycler inventory and capital is uncertain. Therefore, recyclers should strengthen fund management, establish insurance mechanism and prepare reserves to prevent the impact of external variable fluctuations on recyclers' funds. At the same time, in view of the uncertainty caused by exogenous variables related to manufacturers and retailers on recyclers' funds and inventory, recyclers need to deal with it through information sharing, compensation mechanism, incentive and other ways.
