Demand efficiency and planning-input envelope compression in China's near-term power transition: A paired MESSAGEix response-surface assessment

Replication package for "Demand efficiency and planning-input envelope compression in China's near-term power transition: A paired MESSAGEix response-surface assessment." Version v2 (V10 rerun) contents: - Processed model inputs (01_processed_data/), including the 24-cell response-surface design (response_surface_design_lowcp.csv) - Python build, solve and analysis scripts (02_scripts/), including response-surface and fuel-inclusive run scripts - 1,200 main solves, 2,400 response-surface solves and 1,200 fuel-inclusive solves (03_results/) - Calibration and validation data (04_validation/) - Aggregated outputs used in the manuscript (07_SETA_analysis/), including fuel-inclusive metrics and response-surface metrics - IRENA and NREL ATB solar CAPEX source data (05_solar_capex_update_sources/) Key files: - metrics.csv: main cost, P95, standard deviation, CO2 and clean-share statistics by scenario - metrics_fuel.csv: fuel-inclusive accounting robust metrics (12 scenarios x 100 paths) - response_surface_metrics.csv: 24-cell response-surface metrics (eta_ICT x kappa_SG grid) - response_surface_monotonicity.txt: monotonicity report for both axes - accounting_comparison_full_vs_full_fuel.csv: dual-boundary comparison with carbon-payment split - share_decomposition.csv: clean-share numerator/denominator decomposition - FILE_MANIFEST.csv / FILE_MANIFEST.sha256: file integrity manifest GitHub repository: https://github.com/jiangyuhang0707-jpg/seta-messageix-china-power-replication Version v2 updates relative to v1: V10 rerun with the ATB2024 Moderate solar-cost trajectory; added the 2,400-solve response-surface archive and the 1,200-solve fuel-inclusive accounting run; updated README and title.
