本文提出了一个基于Kullback-Leibler分歧的工业本地化统计指标。这一指数特别适合于只有区域一级工业数据的情况。与现有的区域级指数不同，我们的指数可以用来测试工业本地化相对于跨区域的可能位置的假设参考分布的重要性。此外，还可以检验各行业的相对本地化程度。最后，与所有Kullback-Leibler发散指数一样，我们的指数可以分解为代表不同空间聚合水平的本地化的组件。
We propose a statistical index of industrial localization based on the Kullback-Leibler divergence. This index is particularly well suited to cases where industrial data are available only at the regional level. Unlike existing regional-level indices, our index can be employed to test the significance of industrial localization relative to a hypothesized reference distribution of probable locations across regions. In addition, one can test relative degrees of localization among industries. Finally, as with all Kullback-Leibler divergence indices, our index can be decomposed into components representing localization at various levels of spatial aggregation.
