Response to Comment 2 — Data and supporting documentation

Thank you for this request. We have uploaded a Supplementary Data and Code archive containing the raw and processed province-year datasets and the currently available supporting materials used in the study. Specifically, the archive contains the source and MATLAB-compatible data for the Global Super-SBM analysis, efficiency and productivity-index outputs, level-form and natural-log panel datasets, the spatial-weight matrix and Stata command file, fsQCA case-level input data and calibration anchors, and the XGBoost-SHAP input data and corresponding figure. We have also added a variable dictionary, data-provenance notes and a file-level checksum manifest. The same Data Availability statement has been added to the revised manuscript and the submission system under Declarations.
