Essletzbichler J. 美国大都市地区的相关性、产业分支和技术凝聚力，区域研究。演化经济地理学家关于产业关联性对区域经济发展的作用的研究扩展到了许多方法论和实证方向。首先，相关性是用行业之间投入产出联系的强度来衡量的。其次，该指标用于考察美国360个大都市区的行业演变。第三，制定了大都市技术凝聚力的就业加权衡量标准。结果证实，技术相关性与大都市产业组合成员资格和产业进入呈正相关，与产业退出呈负相关。技术凝聚力的分解表明，相关现有产业的选择与产业进入和退出相辅相成，成为都市技术凝聚力变化的主要驱动力。
Essletzbichler J. Relatedness, industrial branching and technological cohesion in US metropolitan areas, Regional Studies. Work by evolutionary economic geographers on the role of industry relatedness for regional economic development is extended into a number of methodological and empirical directions. First, relatedness is measured as the intensity of input-output linkages between industries. Second, this measure is employed to examine industry evolution in 360 US metropolitan areas. Third, an employment-weighted measure of metropolitan technological cohesion is developed. The results confirm that technological relatedness is positively related to metropolitan industry portfolio membership and industry entry and negatively related to industry exit. The decomposition of technological cohesion indicates that the selection of related incumbent industries complements industry entry and exit as the main drivers of change in metropolitan technological cohesion.
