This paper examines the differences in private and government third-party logistics. In general, the paper is interesting and well-organized.

Some specific questions and suggestions:

Introduction:
- After reading introduction section, it would be better if the author(s) explains more clearly the contribution of this study both academically and practically?

Methodology:
- How the data was collected? This information is not found in the manuscript.
- If the data collected through questionnaires, how were questionnaires constructed, linked to theory, worded and tested?
- When the data collected? Who filled out the questionnaire?
- How the 100 sample companies identified? and why these 100 companies, not other companies?
- Even better if the content of the questionnaire was included in methodology section or inserted in the appendix.
- In the manuscript written that the comparison is between 83 private 3PLs with 17 government 3PLs. This comparison seems disproportionate, how the author(s) justifies this?

Results:
- At the beginning of the results, the author(s) suggested to add a table and an explanation of the characteristics of the data such as size, age, and location of the company.

Conclusion:
- The authors suggested to explain the limitations of this study as well as suggestions for future research direction.

Thank you.
