Research on Coordination in a Dual-Channel Green Supply Chain under Live Streaming Mode

Round 1

Reviewer 1 Report

Thank you very much for allowing me to review your work. This work shows that there is effort and perseverance in its preparation. After a thorough review, some errors or mistakes have been detected and should be revised. If you had used the review format proposed by the journal, the review would have been easier. I will comment on the different aspects to be taken into account:

The decisions taken at the time of the modernisation being analysed should be well justified and not respond to subjective assumptions of the researchers.

Figures 3, 4 and 5 provide a lot of information that is not easy for the reader to understand. In particular, figure 3, being a 3D graph, there is information that is lost and overlaps with some data and variables. On the other hand, figure 1 provides very little information to the reader, it would be convenient to include both in this figure and in figure 2 the values of the variables in the graph.

After analysing the results obtained, there is a lack of a discussion that relates the results to the theoretical framework described.

Furthermore, the conclusions drawn are superficial, and could go into more depth on the basis of the different variables analysed.

I reiterate my thanks and look forward to reading your reviews in the near future.

Best regards,

Thank you very much for allowing me to review your work. This work shows that there is effort and perseverance in its preparation. After a thorough review, some errors or mistakes have been detected and should be revised. If you had used the review format proposed by the journal, the review would have been easier. I will comment on the different aspects to be taken into account:

1. The decisions taken at the time of the modernisation being analysed should be well justified and not respond to subjective assumptions of the researchers. Figures 3, 4 and 5 provide a lot of information that is not easy for the reader to understand. In particular, figure 3, being a 3D graph, there is information that is lost and overlaps with some data and variables. On the other hand, figure 1 provides very little information to the reader, it would be convenient to include both in this figure and in figure 2 the values of the variables in the graph. After analysing the results obtained, there is a lack of a discussion that relates the results to the theoretical framework described.

Response: Thanks for the reviewer’s comments. It is revised in the manuscript.

Figure 1 and figure 2 are combined as Figure 1 shown in the revised manuscript, and it reveals that the optimal profit of the manufacturer is increased and the optimal profit of the retailer is decreased with the manufacturer’s bargaining power increases, and they are both more than that in the decentralized model without coordination mechanism.

Figure 3 is adjusted clearly as Figure 2 shown in the revised manuscript.

Figures 4, 5 are adjusted as Figure 3, 4 shown in the revised manuscript, in which we discuss the result in detail and the revised parts are displayed in the revised manuscript.

2. Furthermore, the conclusions drawn are superficial, and could go into more depth on the basis of the different variables analysed.

Response: The analysis of different variables in the conclusions is revised as ‘By comparison with optimal decisions and profits in these models. It is found that the commonly used RSC contract cannot coordinate the supply chain completely, but CS-GS coordination contract can effectively motivate the supply chain members to make the same optimal decisions as that in the centralized model, so as to achieve the maximum profits of the entire system. In addition, each member in the supply chain can obtain more profits by extra profits allocation though bargaining problem, which verifies the feasibility of CS-GS coordination contract achieving a win-win situation. All models are evaluated by numerical analysis, it reveals that CS-GS coordination contract can help to improve green degree of the products, which is benefit to our consumers and the environment. Moreover, when the supply chain members cooperate by CS-GS coordination contract, the discount in the live streaming rooms isn’t always beneficial to the whole supply chain’s interests, which means the manufacturer should make an appropriate discount for the live streaming anchors.’

Response: It is revised as ‘For further research, we propose that the supply chain with multiple manufacturers and multiple retailers can be studied, and the model over multiple periods can also be considered in the future. Moreover, the third party can join the supply chain, such as the government paying for some green investment in the form of subsidies, the logistics enterprise responsible for recycling, and so on. Dynamic and stochastic factors can also be used in the demand function to analyze more complex market environment. Some other coordination mechanisms can be proposed in further study. Even if the optimal coordination state cannot be achieved, it can also achieve the Pareto optimum.’
