The Optimal Emission Reduction and Recycling Strategies in Construction Material Supply Chain under Carbon Cap–Trade Mechanism

Round 1

Reviewer 1 Report

 

（1）The title of the paper is not attractive enough for readers. The title of the paper suggests not using "Research on".

(2) The research problem of the paper is not clear. According to the research question, the author should also state the research objectives.

（3）  Literature review. I encourage that the authors should provide the research gaps and departure of this study through literature review, not just summarizing the literature in this section.

(4) Figures 3 should be further explained in more details. What means C&T mechanisms?

（5）The logical structure of the whole paper is not very good. I suggest supplementing a technical roadmap for the paper.

（6） “5. Discussion”，The discussion section should also compare the views of other scholars and explain the different views. The content of the discussion should precede the conclusion of the paper.

（7）6. Numerical simulations, Why do you choose literature 37 and 39 for the data of case simulation?

(8) How has the Stackelberg game model been validated and the extent of its validity.

（9）Finally, the review of the literature could have been much stronger.. Such as:

Reviewer 2 Report

 The author proposed a model for recycling strategies in constructon supply chain. A little (not detailed) example or cases were studied.

Many equations were quoted in the paper, more detailed explanation shall be provided. The conclusion of paper shall be enhanced.

The paper is well-written

Reviewer 3 Report

1.      In assumption-1, demand is the function of selling price and carbon emission. But single line is not written about selling price in this assumption.

2.     In assumption 3, what is Cn,Co. Is this standard notation?

3.     Provide managerial insights in separate section.

4.     Upgrade the literature review considering the works: Reduction of pollution through sustainable and flexible production by controlling by-products; Reduction of waste and carbon emission through the selection of items with cross-price elasticity of demand to form a sustainable supply chain with preservation technology.

5. Line 194, check the spelling “receptively”. Fix all these issues in entire manuscript.

Reviewer 4 Report

1-The writing of the paper needs a large amount of revisions. Some statements are really hard to understand

2-Mathematical formulations should be referenced in the text and also you should give more details for some of them specially in the given two models

3-Why did you consider Stackelberg game? Why not considering Nash Equilibrium? 

4-The abstract is not informative and it is not really clear what the authors want to do in the end?

5-In introduction section, the authors should give the required backgrounds of understanding the mathematical models. I can not find such content in the introduction

For example in the abstract the authors have written Police instead of policy

There are a lot of English writing points. In some sections the the sentence is correct from Grammatical aspect while the concept is not clear
