Sources of Variation in Economic Impact Multipliers
本文指出旅游组织在复制经济影响分析或比较结果时，感知到的差异常因乘数测量的人为因素和经济结构变化而虚假，并分析了四种导致虚假比较的乘数变异来源。
The conceptual arguments and empirical analyses in the article illustrate that when tourism organizations replicate economic impact analyses and/or compare their results with those reported by others, perceived differences often are specious because they are attributable to artifacts in multiplier measurement as well as to changes in the structure of host economies. Four sources of variation in multipliers that may result in specious comparisons are addressed: differences in specifications of the three main types of models used in economic impact analyses, semantic and definition confusion, changes in communities’ economic structures, and calibration and decision rule changes.
