经济活动的多样化和专业化哪个更好地促进了技术变革和随后的经济增长，一直是经济学文献中激烈辩论的主题。本文的目的是考虑经济活动构成对创新的影响。我们测试的是，在一组狭隘集中的经济活动中，经济活动的专业化是否更有利于知识溢出，或者多样性是否通过将互补的活动聚集在一起，更好地促进创新。这些证据为多样性理论提供了相当大的支持，但对专业化理论的支持却很少。(C)1999 Elsevier Science B.V.保留所有权利。果冻分类。O3、O1。
Whether diversity or specialization of economic activity better promotes technological change and subsequent economic growth has been the subject of a heated debate in the economics literature. The purpose of this paper is to consider the effect of the composition of economic activity on innovation. We test whether the specialization of economic activity within a narrow concentrated set of economic activities is more conducive to knowledge spillovers or if diversity, by bringing together complementary activities, better promotes innovation. The evidence provides considerable support for the diversity thesis but little support for the specialization thesis. (C) 1999 Elsevier Science B.V. All rights reserved. JEL classification. O3, O1.
