火灾相关的危害和事件是一种非常普遍的现象，对人类社会产生了严重影响，因此许多组织长期以来一直在努力减轻火灾及其造成的损失。人们普遍认为，消防性能评估对于此类工作至关重要。在本文中，我们提出了一种基于数据包络分析的新方法，用于美国州级消防效率分析。为此，消防系统被概括为一个创新的两级网络过程，其中第一阶段的火灾危险防御子系统后面是第二阶段的火灾事故扑救子系统。此外，中间产出和最终产出都是不良指标。消防支出是一种共享资源，在管理可处置性下建模，因为它可以有意识地用于减少火灾和火灾损失。通过对2010年至2014年数据的实证研究发现：（1）德克萨斯州、加利福尼亚州、纽约州、佛罗里达州和伊利诺伊州是火灾发生率最高的五个州。 （2）美国整体消防效率平均为0.590，州级消防绩效相对较低。 (3) 怀俄明州、佛蒙特州和罗德岛州是效率最高的三个州，而爱荷华州、阿肯色州和宾夕法尼亚州是效率最低的州。此外，（4）对于大多数州来说，火灾事故扑救效率更有可能高于火灾危险防御效率。 （5）从更大范围来看，将所有州分为八个区域，远西部地区的消防效率最高，而东南部和平原地区的效率得分最低。有趣的是，（6）结果还表明，各州人均消防支出增加1%将导致消防效率提高2.6893%。
Fire-related hazards and incidents are a very common phenomenon that affects human society heavily, so many organisations, over a long period of time, have made efforts to mitigate fires and the caused damages. It is widely acknowledged that an evaluation of fire protection performance is critical for such efforts. In this paper, we propose a new data envelopment analysis-based approach for fire protection efficiency analysis in the United States at the state level. For this purpose, the fire protection system is generalised as an innovative two-stage network process, in which the fire hazard defence subsystem in the first stage is followed by a fire incident fighting subsystem in the second stage. Further, both intermediate outputs and final outputs are all undesirable measures. The fire protection expenditure, a kind of shared resources, is modelled under managerial disposability since it can be intentionally used to reduce fires and fire damages. Based on an empirical study of data from 2010 to 2014, we find that: (1) Texas, California, New York, Florida, and Illinois are the top five states prone to fire incidents. (2) The United States as a whole has an average fire protection efficiency of 0.590, implying relatively low fire protection performances at the state level. (3) Wyoming, Vermont, and Rhode Island are the top three most efficient states, whereas Iowa, Arkansas, and Pennsylvania are ranked the least efficient. Further, (4) the fire incident fighting efficiency is more likely to be higher than the fire hazard defence efficiency for most states. (5) Looking at larger scale by grouping all states into eight areas, the Far West has the highest fire protection efficiency, while Southeast and Plains areas have the lowest efficiency scores. Interestingly, (6) the results show also that a 1% increase in the fire protection expenditure by states per capita will result in a 2.6893% improvement in fire protection efficiency.
