What Determines the Scope of the Firm Over Time? A Focus on Institutional Relatedness
提出除了产品关联性，制度关联性（企业与主导机构的非正式联系）也影响企业边界，并通过纵向和跨国比较研究，为制度基础的企业多元化理论做出贡献。
“What determines the scope of the firm?” is one of the most fundamental questions in strategic management. We argue that, in addition to product relatedness, a focus on institutional relatedness—defined as an organization's informal linkages with dominant institutions that confer resources and legitimacy—helps answer this question. We address this question both longitudinally (firms in developed and emerging economies over time) and cross-sectionally (developed versus emerging economies), thus contributing to an institution-based theory of corporate diversification.
