Analysis of Quality Risk Transmission in the New Retail Service Supply Chain System with Value Co-Creation

The development of emerging technologies promotes the transformation and upgrading of the retail business. However, the new retail service supply chain system’s node enterprises cannot meet quality supply and demand requirements, which leads to quality risks. The quality risks cascade through the system and are amplified, and thus affect overall performance. Therefore, it is necessary to clarify the law of quality risk transmission and realize risk control. In our work, (1) an improved model for quality risk transmission in the new retail service supply chain based on the infectious disease model is developed, (2) we introduce value co-creation rate and control factors from a value co-creation perspective, (3) and solve the threshold and equilibrium point of the service chain node, and conduct a simulation to reveal the quality risk transmission law. The main conclusions are as follows: (1) there is a threshold in the risk transmission system, the larger the threshold the more beneficial it is to control the transfer of risks; (2) the value co-creation rate influences the quality risk transmission process, with the susceptible state value co-creation rate significantly influencing the proportion of immune state numbers, while the opposite is true for the infected state value co-creation rate; (3) both inhibitory and facilitative control factors influence the transmission process of quality risk in the new retail service supply chain. Thus, the value co-creation behavior and risk control measures should be adopted in time to increase the transmission threshold to effectively curb the risk transmission. It will improve the overall quality level of the supply chain so that multiple stakeholders can achieve value co-creation.
