Analysis of the Spatial Distribution Characteristics of Residences and Workplaces under the Influence of Metro Transportation in Metropolises from the Perspectives of Accessibility and Travelers’ Industries: The Case of Guangzhou

Round 1

Reviewer 1 Report

The topic of spatial distribution characteristics of residence and workplace in metropolises is meaningful for urban studies, the text takes Guangzhou (one of the biggest urban metropolitan in China) as a study case that could soundly support the research of this topic. The two contributions of analyzing accessibility to residences and workplaces around metro stations simultaneously and discussing different-industry occupant’s accessibility were interesting and properly described in the paper. The research data was sufficient and the methodology was advisable. However, there are some limitations in this study that needs to be further improved:

1. The literature review needs further improvement. To strengthen the research gap and meanings of this study, more citations should be added.

2. Definitions of some concepts like metropolises, metropolitan suburbanization, and spatial mismatch are not clearly expressed. It is better to have clear definitions of their characteristics, scale, function, and so on for such concepts.

3. The conclusions were mainly constrained to Guangzhou but did not have a general insight into other metropolises. To further improve its scientific research meaning, it is better to have a comparison analysis between Guangzhou and other metropolitan such as Beijing and Shanghai, and the conclusions need deepen and summarized.

4. More background introduction of metro and industries development and their relationship in Guangzhou should be described more comprehensively.

5. Data resources and the precise data structure of the sixth national census in China should be provided.

Reviewer 2 Report

1.    In Abstract，“first, the spatial separation of residence and workplace is not apparent along the metro lines”, “showing that metro transportation has a positive effect on easing the spatial separation problem of residence and workplace”, I don't think this result is necessarily related to the phenomenon. 

2. The definition of the “Accessibility to residence and Accessibility to workplace” should be clearly given in text. 

2.     The resolution of the Figure 2(a) is too low. 

3.     In Figure 2, People accessing to residence and accessing to workplace should be shown the information of “in or out of stations”. 

4. L306, “ 50% of people take metro to and from work,” this sentence may be incorrect. 

5.    The contents in Introduction are weak and should be mainly introduced.

6.    The conclusion of the paper is based on “Influence of Metro Transportation”, so it is should be explained the influence of other factors, like weather, public transportation etc during this time.

Reviewer 3 Report

The introduction part should be improved with more references. Latest papers should be given.

English should be improved in table 4.

 which regression analysis methods were adopted in In 3.2.2.? They should be explained.

In the study,the 2SFCA method was implemented. The method needs more  explanation. There should be at least one more method implemented and compared.

Which program or application was used to gain the results? It should be explained.
