5. Review Comments to the Author

Please use the space provided to explain your answers to the questions above. You may also include additional comments for the author, including concerns about dual publication, research ethics, or publication ethics. (Please upload your review as an attachment if it exceeds 20,000 characters)

Reviewer #1: I think the structure of the manuscript is clear. It describes a technically reliable scientific research, and can draw a more appropriate and rigorous analysis based on the derivation results. The biggest innovation of the manuscript is to include the consumers as the subject in the evolutionary game model, and explore the role of consumer feedback in the regulatory system. However I think there are still a few errors in the manuscript.

Firstly, equation (16) on page 14 should be “The expected profit when the government supervision department chooses loose supervision”, but in the manuscript it is “The expected profit when the government supervision department chooses strict supervision”.

Secondly, first three lines of the first paragraph on page 17 , ”Figure 5 shows that with the increase in the probability of consumer complaints, the probability of strict supervision by government departments is gradually increasing, the probability of non-collusion of e-commerce platform is gradually decreasing.” I think it should be ” Figure 5 shows that with the increase in the probability of consumer complaints, the probability of strict supervision by government departments is gradually increasing, the probability of collusion of e-commerce platform is gradually decreasing.”. I do not know if it is my misunderstanding or the author accidentally wrote it wrong.

Thirdly, last paragraph on page 17, ”Until the online seller stabilized and chose to provide high quality green products, the government's strategic choices gradually stabilized over loose supervision, and the e-commerce platform strategy choice gradually stabilized against collusion.……Once the strategy choice of online seller is stable in providing high quality green products, the e-commerce platform and the government supervision department do not need to monitor the online seller, and they can guarantee the quality of the green products themselves. At this time, the e-commerce platform tends to collusion, the government supervision department tends to loose supervision.” I think these two sentences are inconsistent, I hope the author can check them further.

Finally, I would like to make a suggestion. I think in the manuscript the statement of strict supervision and loose supervision of the government supervision department is not particularly clear. I think the authors can clearly point out that when the government supervision department chooses strict supervision, regardless of whether the consumer complains, the government department will punish the online seller and the e-commerce platform ; when the government department chooses loose supervision, only when the consumer complains, the government department will punish the two parties . I think in this way it will be easier for readers to understand this part clearly.
