摘　　要：文章以我国煤炭行业面板数据为基础,并以其差异性为依据将我国25个主要产煤省份划分为三大不同规制类型的区域,运用三阶段DEA方法测算其投入产出效率,并通过回归分析进一步考察了安全规制强度对于三大区域生产效率的差异化影响。结果表明：安全规制强度与煤炭行业的生产效率呈倒U型关系,且安全规制强度与各区域生产效率的显著程度存在差异。Based on the panel data of China＇s coal industry and its differences, this paper divides China＇s 25 major coal-pro- ducing provinces into three types of regions according to the different regulations, and uses three-stage DEA method to estimate the input-output efficiency. The paper also further investigates the differentiated influence of safety regulation intensity on these three regions＇ production efficiency through regression analysis. The result shows that the relationship between the safety regula- tion intensity and the production efficiency of coal industry is of an inverted-U shape, and that the correlation among the three re- gions is different.
