摘要
准确评估地震的直接经济损失是一个比较困难的问题。主要介绍了用以有形资产为基础统计指标的经济统计学方法来评估地震灾害直接经济损失,包括两种评估模型,即灾区法人单位比重法和综合震害系数法。这些方法在汶川地震损失评估中得到了验证,是目前比较科学合理的经济学方法,提高了灾害损失评估的时效性和准确性。
The precise evaluation of the direct economic loss from earthquakes is a rather difficult issue. This article introduces an economic statistical approach with tangible assets as a basic statistical indicator to evaluate the direct economic loss from an earthquake disaster. This approach involves two evaluation models, namely, disaster ar- ea legal entity rating method and the overall earthquake disaster evaluation method. These methods have been vali- dated in the loss evaluation of Wenchuan earthquake, and are relatively rational and scientific economic methods under current conditions in the improvement of the correctness and currency of disaster loss evaluation.
