How regions diversify into new jobs: from related industries or related occupations?
利用挪威2009-2014年所有劳动力市场区域的雇主-雇员数据，研究区域多样化进入新工作岗位（即独特的产业-职业组合）时，是依赖相关产业还是相关职业，发现两者均有促进作用且互补。
This paper adds a multidimensional perspective to the study of related diversification. We examine how regions diversify into new jobs – defined as unique industry-occupation combinations – asking whether they do so from related industries or related occupations. We use linked employer-employee data for all labour market regions in Norway, covering the time period 2009–2014. Diversification into new jobs is more likely in the presence of related occupations and industries in a region. Furthermore, occupational and industrial relatedness have complementary effects on diversification. Occupational relatedness and its interaction with industrial relatedness are particularly important for diversification into more complex activities.
