Reviewer 2 Report
The article is very interesting and addresses important contemporary economic issues and problems.
What is missing from the abstract is a clearly stated research objective. It is imperative that this is supplemented.
Various currencies appear in the introduction. It will be difficult for researchers outside China to imagine the scale of the phenomena described. I suggest converting the yuan to USD. The coherence of the text will be maintained and it will make analysis easier.
There is no information in the introduction regarding the data that will be used in the study (only a brief reference).
The authors use the wrong way to refer to the literature. Please check the Publisher's guidelines and adjust the references in the text as required.
Line 176 - beginning of sentence - something is wrong.
The article uses very old data, some more than 20 years old. In my opinion, this can significantly obscure the picture of the analyses carried out.
You should use an equation editor for all formulas (e.g. line 250). Please check throughout the paper.

Reviewer 3 Report
The work presented is here is the result of an intense research of China's Service Industry. There are some (minor) issues which should be corrected:
- The introduction mentions some numbers about Chinas economy (e.g. growth rate etc.). These numbers are not referenced at all, please include a valid reference where these numbers come from. Also, the currency used is yuan (45.5 trillion yuan) as well as US Dollars ($294.76). This is rather confusing, so I suggest to use either one currency or both currencies on each measurement.
- The model creation is intransparent and it's hard to understand where the equations (1), (2) and (3) have their origins. Please provide either a reference or a logical thread here.
