The greatest limitation for carrying out intersectoral studies at the regional level is the lack of regional input–output tables. This study compares various indirect methods to estimate regional output multipliers in 15 regions of Chile through Monte Carlo simulation. The augmented Flegg location quotient (AFLQ) method (δ = 0.5) is chosen since it presents the best behaviour to estimate regional input coefficients and output multipliers. However, the value of δ is sensitive to the number of regions and/or sectors and to the use of simulated or real sectoral gross domestic product (GDP) in each region. So, it is recommended that when it is possible, a simulation of Monte Carlo simulation be carried out to select this parameter in each country and not simply adopt values extracted from the literature.

智利区域的区域投入系数和产出乘数的估计

在区域层面开展跨部门研究的最大限制是缺乏区域投入产出表。本研究比较了通过蒙特卡罗模拟估算智利 15 个地区的区域产出乘数的各种间接方法。选择增广 Flegg 位置商 (AFLQ) 方法 (δ = 0.5) 是因为它提供了估计区域输入系数和输出乘数的最佳行为。然而，δ 的值对区域和/或部门的数量以及每个区域的模拟或实际部门国内生产总值 (GDP) 的使用很敏感。因此，建议在可能的情况下，进行蒙特卡罗模拟的模拟，以在每个国家/地区选择该参数，而不是简单地采用从文献中提取的值。
