PONE-D-22-35578Quality Adjustment and Analysis of Human Resource Prices in China: Based on a Hedonic Price ModelPLOS ONE

Dear Dr. Ma,

Thank you for submitting your manuscript to PLOS ONE. After careful consideration, we feel that it has merit but does not fully meet PLOS ONE’s publication criteria as it currently stands. Therefore, we invite you to submit a revised version of the manuscript that addresses the points raised during the review process.

Please submit your revised manuscript by Mar 05 2023 11:59PM. If you will need more time than this to complete your revisions, please reply to this message or contact the journal office at plosone@plos.org. When you're ready to submit your revision, log on to https://www.editorialmanager.com/pone/ and select the 'Submissions Needing Revision' folder to locate your manuscript file.

Please include the following items when submitting your revised manuscript:

• A rebuttal letter that responds to each point raised by the academic editor and reviewer(s). You should upload this letter as a separate file labeled 'Response to Reviewers'.
• A marked-up copy of your manuscript that highlights changes made to the original version. You should upload this as a separate file labeled 'Revised Manuscript with Track Changes'.
• An unmarked version of your revised paper without tracked changes. You should upload this as a separate file labeled 'Manuscript'.

If you would like to make changes to your financial disclosure, please include your updated statement in your cover letter. Guidelines for resubmitting your figure files are available below the reviewer comments at the end of this letter.

If applicable, we recommend that you deposit your laboratory protocols in protocols.io to enhance the reproducibility of your results. Protocols.io assigns your protocol its own identifier (DOI) so that it can be cited independently in the future. For instructions see: https://journals.plos.org/plosone/s/submission-guidelines#loc-laboratory-protocols. Additionally, PLOS ONE offers an option for publishing peer-reviewed Lab Protocol articles, which describe protocols hosted on protocols.io.

Reviewer #2: The minor issues have been addressed in the article in a good manner and hence recommended for publication.

Reviewer #3: Report on: Quality Adjustment and Analysis of Human Resource Prices in China: Based on a Hedonic Price Model

Thank you for entrusting me with the opportunity to review the paper. I would like to commend you on your work and the interesting findings presented in the paper. However, I would like to provide some feedback regarding the introduction section.

After carefully examining the abstract section, I would like to provide some suggestions for improvement. It appears that the abstract contains lengthy sentences and lacks proper structuring. To enhance clarity and readability, it is recommended to break down long sentences into shorter, more concise ones. This will allow readers to grasp the main points more easily. Additionally, organizing the information in a logical manner will aid in understanding the key elements of the paper.

The Introduction is long and loosely connected. It should be improved and better written. The introduction should, very clearly, highlight the aims, method, results and contributions of the paper. Some of the elements of the conclusion could be used in this writing-up of the introduction.

One notable observation is the absence of citations to support the background and context of the study. The introduction serves as a foundation for the research by providing an overview of the existing literature in the field. By referring to relevant research articles, you can establish a framework for your study and highlight the gap that your research intends to address. This will also demonstrate your familiarity with the existing literature and contribute to the credibility of your work.

I understand that your research may be exploring new avenues or addressing unique aspects within the field. However, it is crucial to demonstrate that your work has been situated within the broader scholarly conversation. This will not only lend support to your study but also allow researchers in the field to more easily contextualize and engage with your research.

Additionally, I recommend consulting established journals in your field, as they often publish comprehensive literature reviews and cutting-edge research that may be suitable for citation.

I commend your efforts and the contribution this article can make to the research community. By addressing this concern and enhancing the introduction section with appropriate citations, your article will undoubtedly be strengthened and have a more significant impact on the field.

The discussion section is weak. Kindly improve it. Compare your findings with prior studies’ findings. There is a lack of economic discussion for the regression results of the threshold model.

There are many typo errors in this manuscript, especially for tables. Kindly cross check.

The policy suggestion section need improvement. It is weak in its present form.

The limitations and possible future research directions should be interpreted at the end of the paper, so that the future researchers who are interested in this important topic could carry out follow-up studies.

Please check the grammar of the full text and ask a native English speaker to double-check the edited paper.

Reviewer #4: The authors had revised the paper according to four reviewer’s advices and suggestions. All the concerns from third reviewer had been addressed. The quality of the paper is improved. After two rounds of revision, the paper is valued to be documented.

One minor suggestion is that the unit should be added in the Y axis, for example figure 1 and figure 2. 6.3 can be added in front of section “Limitations and Future Research”
