弗兰肯·K.，货车OOORT F和VERBURG T.（2007）相关品种，无关品种和区域经济增长，区域研究41，685 - 697。在经济理论中，人们可以区分多样性作为区域知识溢出的来源，称为雅各布斯外部性，以及多样性作为保护区域免受外部冲击的投资组合。有人认为，雅各布斯外部性最好的衡量相关品种（部门内），而投资组合的论点是更好地捕捉不相关品种（部门之间）。提出了一种基于熵测度的计算相关簇和不相关簇的方法。使用数据NUTS 3水平在荷兰1996-2002年，它被发现，雅各布外部性提高就业增长，而无关的品种抑制失业增长。生产率增长可以用投资和研发支出等传统决定因素来解释。对区域政策的影响如下。
FRENKEN K., VAN OORT F and VERBURG T. (2007) Related variety, unrelated variety and regional economic growth, Regional Studies 41, 685 -697. In economic theory, one can distinguish between variety as a source of regional knowledge spillovers, called Jacobs externalities, and variety as a portfolio protecting a region from external shocks. It is argued that jacobs externalities are best measured by related variety (within sectors), while the portfolio argument is better captured by unrelated variety (between sectors). A methodology based on entropy measures is introduced to compute related variety and unrelated variety. Using data at the NUTS 3 level in the Netherlands for 1996-2002, it was found that Jacobs externalities enhance employment growth, while unrelated variety dampens unemployment growth. Productivity growth can be explained by traditional determinants including investments and research and development expenditures. Implications for regional policy follow.
