Please use the space provided to explain your answers to the questions above. You may also include additional comments for the author, including concerns about dual publication, research ethics, or publication ethics. (Please upload your review as an attachment if it exceeds 20,000 characters)-->

Reviewer #1: The manuscript is partly technically sound. It presents a clearly described two-site field survey (314 valid responses collected through face-to-face interviews in Zhushan in October 2024 and Dabitou in April 2025) and reports a standard set of measurement checks, including reliability and validity indicators (e.g., Cronbach’s alpha, KMO/Bartlett, composite reliability/AVE, and factor loadings), alongside structural path estimation using bootstrapping in SmartPLS (1,000 subsamples). Nevertheless, several internal inconsistencies and gaps in evidence weaken confidence that the conclusions are fully supported by the reported analyses. In particular, the manuscript mixes and conflates reporting conventions from PLS-SEM and CB-SEM, contains a mismatch between abstracted and tabulated coefficients, and advances comparative claims (e.g., “outperforming” one-dimensional models and “spatial differences” between villages) without clearly presenting the required baseline models, statistical comparisons, or formal tests.

First, the statistical methodology is not reported consistently. While the manuscript describes the use of SmartPLS and the PLS algorithm with bootstrapping, it simultaneously reports CB-SEM-style global fit indices such as χ²/df, CFI, TLI, and RMSEA. This blending of paradigms is confusing and makes it difficult to assess technical adequacy. The authors should explicitly state whether the primary analytical framework is PLS-SEM or CB-SEM and report diagnostics appropriate to that choice. If both approaches were genuinely used (e.g., AMOS alongside PLS, as suggested in the acknowledgments), the manuscript must clearly justify the dual approach, specify which software was used at each stage (measurement versus structural model estimation), and present results in a coherent, methodologically aligned manner.

Second, there is a key inconsistency between the abstract and the results section. The abstract reports the effect of distributive justice as β = 0.58, whereas the structural model table reports β = 0.45 for Distribution Justice predicting overall justice perception. This discrepancy should be corrected throughout the manuscript so that all reported coefficients match the final model output.

Third, the claim that the proposed framework “outperforms traditional one-dimensional models” is not currently demonstrated. Although the model is reported to explain 63% of the variance (R² = 0.63), the manuscript does not provide the results of any one-dimensional baseline models (e.g., Recognition-only, Distribution-only, Participation-only), nor does it report an explicit model comparison using a consistent criterion (e.g., ΔR², predictive performance, or other appropriate SEM comparison metrics). Without such baseline estimation and comparison, the conclusion of “outperformance” is not supported by the evidence presented.

Fourth, the manuscript’s claims of “important spatial differences” between villages are not adequately substantiated with explicit quantitative testing. The abstract advances mechanism-level explanations (e.g., capital-driven monopolies suppress participation in Dabitou, while governance structures strengthen recognition in Zhushan), and the Results/Discussion provides narrative “case evidence,” yet it remains unclear what statistical tests support between-village differences. If the authors intend this as a quantitative comparison, they should report per-village sample sizes and conduct appropriate statistical analyses (e.g., mean comparisons on constructs, multi-group analysis in SEM, and—crucially—measurement invariance testing where relevant). If the inference is primarily qualitative, then the paper should describe the qualitative design, sampling, and analytic procedures more rigorously and temper causal language accordingly.

Fifth, measurement development is insufficiently transparent and contains contradictions. The manuscript states that 25 items were reduced by removing 9 low-loading items, leaving 16 items; however, it later refers to “removing two items” while still retaining “the remaining 16 items,” which is mathematically inconsistent unless intermediate versions existed. In addition, several retained indicators have notably low factor loadings (e.g., P3 = 0.53 and distribution indicators as low as ~0.61), despite the earlier claim that low-loading items had already been eliminated. The authors should provide a clear item-retention flow (initial pool → pretest modifications → final instrument), explicitly list removed items at each step, justify the retention of lower-loading indicators (or revise/remove them), and demonstrate whether conclusions are robust to alternative measurement specifications.

Sixth, the proposed Spatial Justice Index (SJI) weighting scheme appears potentially circular and requires stronger justification. The index is presented as SJI = 0.45×Distributive + 0.32×Recognition + 0.23×Participation, apparently derived from standardized model effects. This risks overfitting because the weights are extracted from the same sample/model used to validate the index, yet the index is framed as an operational tool. The authors should strengthen the rationale for the weights (normative and/or empirical) and include sensitivity analyses (e.g., equal weights, alternative weighting schemes, or cross-validation). If model-derived weights are retained, the index should be presented as context- and sample-specific rather than generalized.

Finally, several additional points should be addressed to strengthen rigor and presentation. The manuscript reports bootstrapping with 1,000 subsamples; this is often considered minimal in SEM practice, so increasing the number of resamples and reporting confidence intervals for path coefficients would improve stability and interpretability. Moreover, some proposed policy thresholds (e.g., “30% attendance” or “50% agenda items co-proposed”) read as normative and are not clearly derived from the presented data, so these should be justified empirically or softened in tone. The limitations (e.g., underrepresentation of youth and reliance on perceptual survey data) are appropriately acknowledged, but the abstract and discussion should reflect these limitations more consistently by avoiding overly strong causal language and by framing findings as associative rather than deterministic where warranted.

Reviewer #2: 1. Spatial Justice Index (SJI) derivation is statistically invalid – Path coefficients cannot be directly used as policy weights. Remove the SJI formula or clearly state it is illustrative only, with proper justification.

2. Severe age bias undermines generalizability – Only 9.6% of respondents are under 25. Temper claims about global scalability and frame findings as specific to aging, low-education rural populations.

3. Village comparison lacks statistical support – Pooled SEM cannot support claims of differences between Zhushan and Dabitou. Either conduct multi-group analysis or reframe as qualitative observations.

4. Low factor loading for item P3 (0.53) – This is below the conventional threshold of 0.60. Report model fit without P3 or justify its retention.

5. Insufficient theoretical justification for rural-urban adaptation— Explain why rural justice dynamics differ from urban (depopulation, tourism, aging) with references to rural geography literature.

6. Missing chi-square p-value – Report the p-value for the chi-square test (not just χ²/df = 2.31) and discuss implications for model fit.

7. Oral consent details insufficient – Specify whether consent scripts were IRB-approved, how comprehension was verified, and how capacity was assessed for elderly participants.

8. Data availability statement ambiguous – Clarify whether raw survey data (314×16) will be published as supporting information or provide access conditions.

9. Social desirability bias not addressed – Face-to-face interviews by researchers may bias responses about governance. Add a limitation paragraph and describe mitigation strategies.

Revision 1

Responses to Reviewer #1

Reviewer's Summary: The manuscript is partly technically sound... several internal inconsistencies and gaps in evidence weaken confidence that the conclusions are fully supported by the reported analyses.

Response: We thank the reviewer for this thorough and constructive assessment. We have carefully addressed each of the specific points raised, as detailed below.

Comment 1: The statistical methodology is not reported consistently. While the manuscript describes the use of SmartPLS and the PLS algorithm with bootstrapping, it simultaneously reports CB-SEM-style global fit indices... The authors should explicitly state whether the primary analytical framework is PLS-SEM or CB-SEM and report diagnostics appropriate to that choice.

Response: We fully acknowledge this critical inconsistency in the original submission. We have taken the following steps to rectify this issue:

(1)Clarified Analytical Framework: We have added a dedicated subsection titled "Analytical Approach" in the Materials and methods section (Page12, Line 359-368). This section explicitly states that Partial Least Squares Structural Equation Modeling (PLS-SEM) was the sole analytical framework employed, justified by the study's prediction-oriented nature and moderate sample size. We confirm that all analyses were conducted using Smart PLS 3.0.

(2)Removed Inappropriate Fit Indices: We have completely deleted the former Table 11 (Structural Model Fit Indices) and all associated text that reported CB-SEM metrics such as χ²/df, CFI, TLI, and RMSEA. These indices are not appropriate for variance-based PLS-SEM.

(3)Corrected Terminology: In the Path Analysis section and in Table 12, we have replaced the CB-SEM term "C.R. Value" with the PLS-SEM standard "T Statistics".

(4)Added PLS-SEM Specific Metrics: We have supplemented the model evaluation with the Stone-Geisser's Q² value to assess predictive relevance. As reported in the Variance Explained and Effect Size Test section (Page 18, Line 525), the blindfolding procedure yielded a Q² value of 0.625, confirming the model's predictive validity.

(5)Corrected Acknowledgments: We have removed the reference to AMOS from the Acknowledgments section to ensure consistency with the sole use of Smart PLS.

Comment 2: There is a key inconsistency between the abstract and the results section. The abstract reports the effect of distributive justice as β = 0.58, whereas the structural model table reports β = 0.45...

Response: We apologize for this typographical error. The correct standardized path coefficient is β = 0.45. We have corrected this throughout the entire manuscript, including the Abstract (Page 1, Line15), to ensure consistency with the final model output presented in Table 12.

Comment 3: The claim that the proposed framework "outperforms traditional one-dimensional models" is not currently demonstrated...

Response: We agree with the reviewer that the original phrasing was not supported by a formal model comparison. Following the reviewer's guidance, we have removed all claims of "outperforming" one-dimensional models. In the revised Abstract (Page 1, Line 10]), the text now emphasizes the value of the multidimensional framework in capturing the interconnected nature of justice perceptions, stating: "...highlighting the interconnected nature of recognition, distribution, and participation in shaping justice perceptions, a nuance that single-dimension approaches may overlook." We believe this more accurately reflects the contribution of our study without overstating the empirical evidence.

Comment 4: The manuscript's claims of "important spatial differences" between villages are not adequately substantiated with explicit quantitative testing... Either conduct multi-group analysis or reframe as qualitative observations.

Response: This is an excellent point. We have clarified that our discussion of village-specific dynamics is based on qualitative case evidence rather than statistical multi-group analysis. The following revisions were made:

(1) Methodological Clarification: In the Analytical Approach section (Page 12, Line 369-374), we have added a statement: "A total of 314 valid responses were collected, comprising 149 from Zhushan Village and 165 from Dabitou Village. Given the modest sub-sample sizes, formal multi-group analysis was not conducted; village-level comparisons in this study are therefore based on qualitative case evidence rather than statistical inference."

(2)Tempered Language: We have revised the language throughout the Abstract and Results sections to clearly frame spatial contrasts as qualitative observations. For example, the Abstract now states: "Qualitative contrasts suggest how endogenous governance in Zhushan may strengthen recognition, while capital-driven monopolies in Dabitou appear to suppress participation." In the Results section (Page 1, Line 17-20), we anchor these observations in interview excerpts and explicitly note that they are illustrative case contrasts.

Comment 5: Measurement development is insufficiently transparent and contains contradictions... provide a clear item-retention flow... justify the retention of lower-loading indicators.

Response: We have thoroughly revised this section for transparency and accuracy.

① Item-Retention Flow: We have added a new Table 2 (Item Screening and Retention Process) in the Questionnaire Design section (Page 10), which clearly outlines the three stages from the initial 25-item pool to the final 16-item instrument.

② Contradiction Removed: The contradictory sentence "After removing two items..." has been removed. The text now clearly states that 9 items were removed during the pre-test, resulting in the final 16 items.

③ Justification for Lower Loadings: We thank the reviewer for this important methodological observation. We have addressed this concern through both empirical sensitivity analysis and transparent theoretical justification, as detailed below:1.Sensitivity Analysis. We re-estimated the structural model after temporarily removing P3 from the participation justice construct. The key results are summarized in the table below (reproduced from our response to Reviewer #1, Comment 5, for ease of reference):The analysis demonstrates that removing P3 results in only marginal changes to the path coefficient (β = 0.28 → 0.26, p remains <0.01) and model fit (R² = 0.63 → 0.62). The substantive conclusions of the study are unchanged.

指标 保留P3的原始模型 删除P3后的模型 变化

Participation Justice的CR 0.82 0.85 +0.03

Participation Justice的AVE 0.53 0.58 +0.05

路系数�Participation → Overall Perception 0.28 0.26 -0.02

该路径的T Statistics 4.67 4.21 仍显著(p<0.001)

该路径的P Value 0.003 0.005 仍<0.01

Overall Perception的R² 0.63 0.62 -0.01

Participation Justice的f2 0.08 0.07 -0.01

④ Justification for Retention. Based on the robustness of the findings and the theoretical importance of “fair feedback” to the participation justice construct, we elected to retain P3. This decision follows established PLS-SEM guidelines indicating that loadings between 0.40 and 0.70 are acceptable in exploratory social science research when the indicator contributes substantively to the construct’s theoretical domain and its removal does not compromise composite reliability or average variance extracted.

⑤ Acknowledgment of Limitation and Path Forward. We acknowledge that the loading of P3 (0.53) remains below the conventional threshold of 0.60. While our sensitivity analysis confirms that its removal does not alter the substantive conclusions, future scale development efforts should refine or replace this item (e.g., by rewording “fair feedback” more concretely or splitting it into multiple items) to improve psychometric robustness. We have noted this limitation in the revised manuscript (Validity Analysis section, Page 15, Line 426-435) and again in the Limitations section (Page 31, Line 998-1002) to guide future research.

Comment 6: The proposed Spatial Justice Index (SJI) weighting scheme appears potentially circular... should be presented as context- and sample-specific rather than generalized.

Response: We fully concur with this insightful methodological critique. We have significantly revised the presentation of the SJI in the Limitations and Future Research Directions section (Page 30, Line 888). The formula is now described as an "exploratory and illustrative formulation" and a "context-specific, sample-dependent illustration." We have added strong caveats stating: "We emphasize that this formulation is statistically derived from a single sample and should not be interpreted as a generalizable policy weight... This index is presented solely to illustrate how empirical findings might inform the conceptual development of future assessment tools, pending rigorous cross-validation and sensitivity testing." We have also removed language that framed it as an "operational tool."

Comment 7: Several additional points... bootstrapping with 1,000 subsamples... policy thresholds... limitations...

Response: We have addressed each of these points as follows:

(1)Bootstrapping: We have re-run the analysis with 5,000 subsamples (previously 1,000). The updated T Statistics and P Values are reported in Table 12 and referenced in the Path Analysis section (Page19,Line 547).

(2)Policy Thresholds: We have removed the specific, unsupported numeric thresholds (e.g., "30% attendance") from the Limitations section. The text now speaks in terms of general principles and benchmarks that would require further empirical calibration.

(3)Limitations and Language: We have significantly expanded the Limitations section (Page30, Line 939) to explicitly discuss the age bias in the sample and the potential for social desirability bias. We have also performed a full pass of the manuscript to temper causal language, replacing terms like "demonstrates" with "suggests" or "indicates" where appropriate.

Responses to Reviewer #2

Comment 1: Spatial Justice Index (SJI) derivation is statistically invalid -- Path coefficients cannot be directly used as policy weights. Remove the SJI formula or clearly state it is illustrative only, with proper justification.

Response: As noted in our response to Reviewer #1 (Comment 6), we have thoroughly revised the SJI section. We have retained the formula solely for illustrative purposes and have added explicit, strong caveats that it is not a validated policy weight and is specific to this sample. We hope this addresses the reviewer's statistical validity concern.

Comment 2: Severe age bias undermines generalizability -- Only 9.6% of respondents are under 25. Temper claims about global scalability and frame findings as specific to aging, low-education rural populations.

Response: We agree. We have taken the following actions:

(1)Revised Abstract and Conclusion: We have removed claims of global scalability. The Abstract (Page1,L22) now describes the metric as "preliminary" and relevant for "similar aging rural contexts."

(2)Expanded Limitations: We have added a dedicated subsection titled "Sample Representativeness and Age Bias" in the Limitations section (Page30,L939). This section details the age distribution, discusses the underrepresentation of youth, and explicitly cautions against generalizing the findings to younger or demographically different populations.

(3)Tempered language in the Author summary: We have further tempered the language in the Author summary by adding an explicit applicability caveat. Specifically, we now state that the proposed tool “is most directly applicable to aging, depopulating rural contexts and should be validated in younger populations before broader generalization.” This change ensures that the summary accurately reflects the sample limitations and avoids overstatement of generalizability.

Comment 3: Village comparison lacks statistical support -- Pooled SEM cannot support claims of differences between Zhushan and Dabitou. Either conduct multi-group analysis or reframe as qualitative observations.

Response: As detailed in our response to Reviewer #1 (Comment 4), we have reframed all between-village contrasts as qualitative observations. We have added a clear statement in the Analytical Approach section explaining the decision not to perform MGA due to modest sub-sample sizes. The language in the Results section has been modified to anchor these contrasts in interview data and field notes.

Comment 4: Low factor loading for item P3 (0.53) -- This is below the conventional threshold of 0.60. Report model fit without P3 or justify its retention.

Response: We have addressed this with a sensitivity analysis (Page 15,L426). The analysis demonstrates that removing P3 results in only marginal changes to the path coefficient (β = 0.28 → 0.26, p remains significant) and model fit (R² = 0.63 → 0.62). Based on the robustness of the findings and the theoretical importance of "fair feedback" to the participation justice construct, we have justified its retention. This is a more transparent and rigorous approach than simply removing the item. The details of this analysis are presented in the Validity Analysis section.

Comment 5: Insufficient theoretical justification for rural-urban adaptation--- Explain why rural justice dynamics differ from urban (depopulation, tourism, aging) with references to rural geography literature.

Response: We have added a new, dedicated paragraph in the Introduction (Page 4, Line 157) titled "Why Rural Spatial Justice Requires Distinct Theoretical Treatment." This section systematically outlines three key structural differences between urban and rural contexts: demographic trajectories (depopulation/aging), political economy of spatial production (tourism/external capital), and the socio-cultural function of public space (collective memory/ritual). This addition provides a robust theoretical foundation for our rural-specific operationalization of spatial justice.

Comment 6: Missing chi-square p-value -- Report the p-value for the chi-square test (not just χ²/df = 2.31) and discuss implications for model fit.

Response: We thank the reviewer for this observation. However, following a comprehensive methodological revision, we have clarified that PLS-SEM is the sole analytical framework. As detailed in our response to Reviewer #1 (Comment 1), we have removed all covariance-based fit indices (including χ² and its associated p-value) from the manuscript. Reporting χ² is not appropriate or recommended for variance-based PLS-SEM. We have instead evaluated model quality using PLS-SEM specific criteria (SRMR, Q², and bootstrapped path significance), which we have reported in full.

Comment 7: Oral consent details insufficient -- Specify whether consent scripts were IRB-approved, how comprehension was verified, and how capacity was assessed for elderly participants.

Response: We have significantly expanded the ethics statement in the Questionnaire Design and Data Collection section (Page 11, Line325). The revised text now specifies that:The verbal script was reviewed and approved by the IRB as part of the protocol.Comprehension was verified by asking participants to restate key points in their own words.For elderly participants, interviewers were trained to assess alertness and orientation before proceeding.All consent outcomes were documented on field record sheets.

Comment 8: Data availability statement ambiguous -- Clarify whether raw survey data (314×16) will be published as supporting information or provide access conditions.

Response: We have added a clear Data Availability Statement after the Acknowledgments section (Page 32). The statement confirms that the minimal anonymized dataset has been uploaded as a Supporting Information file (S1 Dataset) , which will be made publicly available upon publication.

Comment 9: Social desirability bias not addressed -- Face-to-face interviews by researchers may bias responses about governance. Add a limitation paragraph and describe mitigation strategies.

Response: We have added a new subsection in the Limitations section (Page 30,Line 976 ) titled "Social Desirability Bias." This paragraph acknowledges the potential for bias in responses to governance-related questions, describes the mitigation strategies we employed (e.g.,

Reviewer #2: (No Response)

Reviewer #3: Comment:

The authors have submitted a thoroughly revised manuscript that convincingly addresses the substantive methodological and theoretical concerns raised during the initial review. The revisions demonstrate a serious engagement with the feedback, significantly strengthening the paper's rigor, clarity, and scholarly contribution.

The key improvements that warrant acceptance are:

1. Methodological Rigor and Transparency: The authors have decisively clarified the analytical framework, explicitly stating the sole use of PLS-SEM and removing all inappropriate CB-SEM fit indices. The addition of a dedicated "Analytical Approach" subsection, the correction of terminology, and the inclusion of PLS-specific metrics (e.g., Q²) bring the methodology reporting to a high standard. The transparent presentation of the item-screening process (new Table 2) and the justification for retaining lower-loading indicators (e.g., P3) based on sensitivity analysis and theoretical grounds are commendable.

2. Accurate and Consistent Reporting: The critical inconsistency in the beta coefficient for distributive justice (Abstract vs. Results) has been corrected throughout the manuscript (β=0.45), ensuring internal consistency. All claims have been carefully tempered to align with the evidence.

3. Appropriate Framing of Findings: The authors have correctly reframed claims about "outperforming" one-dimensional models to more accurately highlight the value of their multidimensional approach in capturing interconnected perceptions. Crucially, they have reframed inter-village comparisons (Zhushan vs. Dabitou) as qualitative observations based on case evidence, adding a clear methodological statement that formal multi-group analysis was not conducted due to sample size. This is a responsible and appropriate interpretation of the data.

4. Theoretical Strengthening: The new paragraph in the Introduction, "Why Rural Spatial Justice Requires Distinct Theoretical Treatment," provides a much-needed and robust justification for adapting urban-centered justice theory to rural contexts, effectively addressing a core theoretical gap.

5. Acknowledgment of Limitations and Refinement of Claims: The authors have significantly expanded the Limitations section, thoughtfully addressing critical issues such as sample age bias, social desirability bias, and the illustrative (non-generalizable) nature of the proposed Spatial Justice Index (SJI). The language throughout the manuscript has been tempered, replacing overly causal claims with more measured interpretations.

6. Ethical and Data Transparency: The ethics statement has been expanded with sufficient detail on the oral consent procedure, and a clear Data Availability Statement has been added, meeting journal standards.

In summary, the revised manuscript is now methodologically sound, theoretically grounded, and clearly presented. The authors have successfully transformed a manuscript with potential into a robust and publishable research article that makes a valuable contribution to the fields of rural geography, spatial justice, and traditional village studies. The study's proposed three-dimensional model offers a practical, empirically validated tool for assessing justice perceptions in transitioning rural landscapes.

Therefore, I recommend acceptance of the manuscript in its current form.
