Study on the Spatial and Temporal Evolution Patterns of Green Innovation Efficiency and Driving Factors in Three Major Urban Agglomerations in China—Based on the Perspective of Economic Geography
Round 1
Reviewer 1 Report
Analysis on Spatial -temporal characteristics and Influencing Factors of Green Innovation Efficiency in Three Major Urban Agglomerations in China.
This paper explains the trends of green innovation efficiency and its influencing factors using spatial analysis. The topic is interesting and very relevant. I have a few comments and suggestions.
1. Just a few writing issues
For example the opening sentence "Under the background of the report of the 19th CPC National Congress clearly 40 pointed out that we should unswervingly implement the five new development concepts" . Who is being referred by "we"? Is this a quote or ?
There are some small mistakes in the paper e.g using capital letters instead of small letters and in the variable definition "Renewd employees" ?
2. The authors need to improve their in-text citation style. For example, in the second paragraph, the authors just put a block of references (3-19) . The authors need to insert the cites next to the related explanation, this makes it easier for the readers.
3. There is a need to add other references on environmental regulation and green innovation. For example, the authors write "Foreign empirical research mainly focuses on the green innovation behavior at the industry and enterprise level..." but there is no reference to a foreign research article on green innovation. They can add Mbanyele et al., (2022) as another reference. They can supplement the three references below with others.

Reviewer 3 Report
The paper entitled “Analysis on Spatial -temporal characteristics and Influencing Factors of Green Innovation Efficiency in Three Major Urban Agglomerations in China” aim is to measure the green innovation efficiency of each urban agglomeration, and a spatial model is established to explore the spatio-temporal evolution trend and spatial effect characteristics of green innovation efficiency. To do so, the SBM-DEA efficiency model is used.
The paper is interesting and well written.
However, the following amendments are required before the paper can be published.
1. The authors must clearly explain why they have selected the specific areas of China referred in the methodology, instead of others. Furthermore it must be explained whether these areas can provide results that can be used for more cases as well.
2. Furthermore, the authors must clearly point out the paper’s novelty and contribution in the introduction section.
3. Moreover, the development of some research aims or, ideally, of some research hypotheses would facilitate the understanding of the paper’s aims, results and contribution.
4. The paper lacks of a literature review section. Instead of adding one, the authors should enrich the theoretical part of the introduction section. To do so, the following papers could be referred:

Reviewer 4 Report
There is no need to show equations for DEA analysis when we have software for that.
The method Is highly subjective and expert judgement, so it would be more valuable to explain input variables in the model instead of these absolutely unnecessary formulae.
Only a fraction of patents do become an innovation as you defined it. Why not use some database tracking manufacturing innovations? I’m sure in China there is plenty of statistics.
Page 4-5 – you describe variables you use but not the source of that data so it is a bit unusual not to disclose where from you got them e.g. profits on new products?
The choice of indexes in Table 1. Input-output indicators and descriptive statistics of green innovation efficiency, have nothing to do with variables you are describing that you will be using
I don’t see the purpose of 3.3. Exploratory spatial data analysis (ESDA) – absolutely numbers have no sense when we don’t know what entered the model, and you already displayed graphic analyses and that it more than enough – but we also don’t know which variables you used form Statistical yearbooks you are referring to.
I absolutely do not understand why your already complex subject you include services on page 13. With no referencing.
Second, it is generally believed that industry is a
400 high energy-consuming and high-emission industry, while the service industry is a
401 smokeless economy and green industry, and regional green innovation mainly depends
402 on the service industry.
Page 13, lines 404-418 - pure speculation not grounded in any research or at least not cited.
Page 14 lines 419-442
We already know that government initiatives have consequences, that’s nothing new. You again forgot to cite previous studies. Now, all of the sudden you talk about education and importance of education on innovation and you show variables in table 13 that you use to prove – not sure what- which have again nothing to do with education and consequently innovation.
Page 16 line 482
The level of economic development. (1) The regression coefficient of per capita in- 483 come level is positive and passed the significance test of 1%, indicating that it has a posi- 484 tive impact on the efficiency of green innovation. – where do we actually see that? The rest is also unclear. Name the column and line where we see that.
Page 16 line 496
Generally speaking, the service in- 496 dustry represented by the tertiary industry has more characteristics of green innovation 497 development than the manufacturing industry.
Would you please explain what is green innovation in services since you decided to include them too, and where exactly we see that?
Page 18 Conclusion and enlightenment - usually we say discussion
And it is usually comparison to previous literature

Comment #1:
The method Is highly subjective and expert judgement, so it would be more valuable to explain input variables in the model instead of these absolutely unnecessary formulae.
Response: Thank you for your valuable suggestions. Following your suggestions, we have added detailed explanations and descriptions of the input and output variables. Related updates have been submitted to the manuscript. (Lines 397-484, page 10-12).
Comment #2:
Only a fraction of patents do become an innovation as you defined it. Why not use some database tracking manufacturing innovations? I’m sure in China there is plenty of statistics.
Response: Thank you for your valuable suggestions. As the manufacturing industry involves a wide range of areas, our research can not be very comprehensive, the lack of full excavation of this area of research, we will increase the in-depth study of manufacturing innovation in the future. However, our research tracks the statistical data of "large and medium-sized industrial enterprises" and "industrial enterprises above scale".
Comment #3:
Page 4-5 – you describe variables you use but not the source of that data so it is a bit unusual not to disclose where from you got them e.g. profits on new products?
Response: Thank you for your valuable suggestions. We are very sorry for that in this manuscript and the inconvenience caused to your reading. Following your suggestions, we have supplemented and explained the source of the data and updated it in the manuscript. (Lines 473-483, page 12). e.g. The profits on new products date comes from (Lines 438-444, page 11).
Comment #4:
I don’t see the purpose of 3.3. Exploratory spatial data analysis (ESDA) – absolutely numbers have no sense when we don’t know what entered the model, and you already displayed graphic analyses and that it more than enough – but we also don’t know which variables you used form Statistical yearbooks you are referring to.
Response: Thank you for your valuable suggestions. We are very sorry for that in this manuscript and the inconvenience caused to your reading. First of all, we supplement and explain the variables in section 2.2.3. Secondly, we explain the data used in Section 3.3. The purpose of our section 3.3 study is to explore the global and local spatial distribution characteristics and agglomeration law of the three major urban agglomerations in China, which can better pave the way for the study of the spatial effect of section 3.4, and updated in the manuscript.(Lines 356-386, page 9-10; Lines 589-624, page 16-17 ).
Comment #5:
I absolutely do not understand why your already complex subject you include services on page 13.
Response: Thank you for your valuable suggestions. Here we mainly want to express the tertiary sector, due to a mistake to say services and we have carefully checked and corrected errors. We are very sorry for the mistakes in this manuscript and the inconvenience caused to your reading. (Lines 674-683, page 19).
