鉴于在大冲击后衡量韧性的程度和来源的重要性增加，韧性引起了研究人员的注意。然而，没有普遍同意的韧性衡量标准；现有方法几乎没有关于韧性的行业评估。这项研究提供了一个结构性敏感性指数来衡量地区就业韧性的产业来源，并将其应用于1980-2012年间的日本经济。它提出了一个新的公式，通过部门内和结构变化的影响来量化区域复原力的来源，并得出不同的地方行业如何对区域复原力做出贡献。从时间和地域上考察就业弹性的产业和数量方面，发现日本各县在20世纪90年代后逐渐变得有弹性，增加了地区异质性。此外，结构变化效应不断损害区域韧性，抵消了一些有利的部门内效应。最后，从不同的时间范围来看，弹性改善背后的地区异质性日益增强伴随着产业不均衡性，但从不同的空间角度来看，产业不均衡性与弹性之间的总体关系并不是唯一的。
Given the increase in the importance of measuring the degree and source of resilience after great shocks, resilience has garnered researchers’ attention. However, there is no generally agreed-upon measurement for resilience; the existing approach holds few industrial assessments for resilience. This study provides a structural sensitivity index to measure the industrial sources of regional employment resilience and applies it to the Japanese economy between 1980 and 2012. It presents a novel formula that quantifies the sources of regional resilience by within-sector and structural change effects and extracts how unevenly different local industries contribute to regional resilience. Exploring the industrial and quantitative aspects of employment resilience chronally and geographically reveals that Japanese prefectures gradually became resilient after the 1990s, increasing the regional heterogeneity. Moreover, the structural change effect has constantly hurt the regional resilience, offsetting some favourable within-sector effects. Finally, the increasing regional heterogeneity behind improvements in resilience accompanies industrial unevenness from different time horizons, but the overall relationship between industrial unevenness and resilience is not unique from a different spatial perspective.
