Reviewer 1 Report

 

 Line 66, here need a insertion of year-“Ciftciglu et al.”  The left map in Figure 1 needs a scale.  The figure 2 could be changed into colored one. The manuscript did give a good presentation of research results, but I would like suggest authors increase the space of the discussions.  Those literatures in Chinese needs the words of “in Chinese” added in the reference list.  It needs a more detailed description about how to calculate the index weight in Table 2.

Reviewer 2 Report

The manuscript is well-written and of reasonable interest. I have only a few comments and only one is major.

Table 6: This table needs to be reconfigured to fix column headers and rather than use the obstacle variable nomenclature, use the name of the variable as in the text. For example Z₁₆ is amount of labor. This will make the table useful. At present, the table is meaningless.
