推动西部地区煤炭产业绿色转型对统筹能源安全与区域可持续发展具有重要意义。为此,选取2009—2024年西部11个省级行政区的面板数据,利用SBM-GML(基于松弛测度的全局马尔奎斯特-伦伯格)指数模型测度煤炭产业绿色全要素生产率(GTFP),实证考察数字化转型的影响及其作用机制。研究发现,数字化转型显著提升了西部煤炭产业的绿色全要素生产率,通过生产端技术赋能、管理端协同优化以及要素端配置改善,驱动绿色高质量发展。机制分析表明,技术进步是数字化转型赋能GTFP提升的关键中介路径。异质性分析进一步揭示,该促进效应在西南地区及经济发达省份更为凸显,而经济欠发达地区受限于数字基础设施及人才储备,效应尚不显著。因此应通过强化技术融合、实施差异化区域策略及完善协同制度,释放数字化红利,为在保障能源安全背景下的西部煤炭产业绿色发展提供支撑。
