Stackelberg Game Analysis of E-Waste Recycling Stakeholders under Recovery Time Sensitivity and CRMs Life Expectancy Sensitivity
Round 1
Reviewer 1 Report
The Stackelberg leadership model is a strategic game in economics in which the leader firm moves first and then the follower firms move sequentially. It is named after the German economist Heinrich Freiherr von Stackelberg who published Market Structure and Equilibrium in 1934, which described the model. In game theory terms, the players of this game are a leader and a follower and they compete on quantity.
Authors of this paper, in order to discuss the participation strategy selection of relevant subjects in WEEE recycling, a Stackelberg game model for relation recyclers-remanufacturers-government in WEEE recycling network was constructed, and the system stability strategy and conditions were analyzed.
It is for me extremely interesting not only review work, but also the pleasure of reading such an approach to the issue of recycling. It is a completely different view of recycling, and so different from my technical approach.
As a long-time theorist and practitioner of WEEE metal recycling by pyro-and hydrometallurgical processes, I read this article with great interest. It is a very beneficial, wider than usual view of the issue of WEEE recycling (CRM), combined in a kind of practical intellectual game. For any recycling organizer – remanufacturers it is full of valuable tips that will determine the success of the circular economy. It is important to show how extremely important the state legislative aid is and the financial support of government institutions for recyclers and remanufacturers. The article perfectly shows that recycling is a set of factors without which its proper operation and economic success will not be possible. The article is suitable for wide dissemination for everyone who is close to the problems of recycling (entrepreneurs-recyclers, financiers, environmental protection, and appropriate governmental institutions.
Congratulations to the authors of the work.

Reviewer 2 Report
The authors constructed a Stackelberg game model of "recyclers---remanufacturers---government" in WEEE recycling network, and analyzed the system stability strategy and conditions. The article also contains a comparative discussion and sensitivity analysis under fixed subsidy and variable subsidy. The conclusions come from the research conducted. In my opinion, the paper is well written and its structure is well organized. However, the paper needs some improvements:
1. The main motivations and contribution should be described in more detail in Introduction section.
2. Title of subsection 6.2 “Contributions” must be “Sensitivity analysis” because the authors have presented the analysis to see the impact of on e under fixed subsidy and variable subsidy.
3. Please be careful about all symbols and mathematical expressions in the paper.
4. Future directions are so limited. Add most important and possible directions.
5. The current paper requires a proofreading because I have encountered slight mistakes and grammatical errors.
