This paper studies the determinants of technological catch‐up considering spatial and sectoral aggregation of industries. We investigate how geographical and technological proximity to the technology leader impact regional employment growth. We model technological progress by means of a hierarchical process of catch‐up to the technology leader. We also incorporate measures for knowledge spillover effects to test the roles of competition, specialisation, and diversity at the industry level. Empirical results using data at the county level for different economic sectors (2‐dig NAICS) for the United States indicate that human capital plays a crucial role in promoting sectoral employment growth. The association between technological/geographical distance to the technology leader and employment growth varies across sectors.

技术领导力与部门就业增长：美国各县的空间计量经济学分析

本文研究了考虑行业空间和部门聚集的技术赶超的决定因素。我们调查了地理位置和技术上与技术领导者的接近程度如何影响区域就业增长。我们通过追赶技术领先者的分层过程来对技术进步进行建模。我们还采用了针对知识溢出效应的措施，以测试行业层面上竞争，专业化和多样性的作用。使用美国不同经济部门的县级数据进行的经验结果（2-NAICS）表明，人力资本在促进部门就业增长中起着至关重要的作用。距技术领导者的技术/地理位置距离与就业增长之间的关联因行业而异。
