Abstract

The objective of this paper is to critically review contemporary insights derived from studies that focus on relatedness. A well‐established body of literature has identified three approaches for measuring relatedness, those based on co‐occurrence matrices, industrial hierarchy and resource similarity. From these measures, several authors have begun developing relational networks to capture the branching capabilities of products, industries, technologies and skills. Thereafter the present contribution then shifts from analysing ‘what is' and begins considering what ‘could be'? It argues that the concept of relatedness lies at the heart of deconstructing issues of unrelated diversification and smart specialisation. El objetivo de este trabajo es revisar críticamente las percepciones contemporáneas derivadas de estudios que se centran en el grado de relación. Un acervo de literatura bien establecido ha identificado tres enfoques para medir el grado de relación, que son los basados en matrices de co‐ocurrencia, en la jerarquía industrial y en la similitud de recursos. A partir de estas medidas, varios autores han comenzado a desarrollar redes relacionales para capturar las capacidades de ramificación de productos, industrias, tecnologías y habilidades. Es a partir de ahí que este trabajo deja de analizar “lo que es” y comienza a considerar lo que “podría ser”. Se sostiene que el concepto de grado de relación es una parte medular de la deconstrucción de cuestiones de diversificación no relacionada y especialización inteligente. 本稿の目的は、関連性に注目した研究に由来する現代の洞察を批判的にレビューすることである。関連性を測定する方法として、共起行列を基にした方法、産業の階層構造を基にした方法、リソースの類似性を基にした方法の3つの方法が、かなりの数の研究により確認されている。いくらかの研究者は、これらの方法により、製品、産業、テクノロージー、技術、以上の能力の分岐を捉えるために関係ネットワークの開発をはじめている。その後、本稿は「何が」の分析から「あり得るのは何か」の検討へと移行する。類似性の概念は、非関連多角化とスマート・スペシャリゼーションの問題の分解する中心にあると論じている。
