Abstract

We try to identify the determinants of regional variation in both exploitative and exploratory innovative competencies. Hereby, we focus on how a knowledge‐creation mechanism with specialized externalities differs from one with diversified externalities. Innovative competence in the US is measured by local patenting performance; exploitative and exploratory patenting performances are distinguished by the degree of backward citation. Based on the extended knowledge‐production function, including the two agglomeration externalities, our findings show that specialized externalities are associated with exploitation, while diversified externalities are positively related with both exploration and exploitation, regardless of industrial sectors. Este artículo trata de identificar los determinantes de la variación regional en las competencias innovadoras de explotación y exploratorias. De esta manera, se centra en cómo un mecanismo de creación de conocimiento con externalidades especializadas difiere de uno con externalidades diversificadas. Las competencias innovadoras en los EE.UU. se miden por el rendimiento de las patentes locales; los resultados del patentado con fines de explotación y exploratorios se distinguen por el grado de citas retroactivas. Con base en la función ampliada de producción–conocimiento, incluidas las dos externalidades de aglomeración, los resultados muestran que las externalidades especializadas están asociadas con la explotación, mientras que las externalidades diversificadas están positivamente relacionadas tanto con la exploración como con la explotación, independientemente de los sectores industriales. 本稿では、搾取的なコンピテンシーと探索的イノベーション的なコンピテンシーの決定因子の特定を試みる。ここでは、知識‐創造のメカニズムの特化的外部性を伴うものと多様化した外部性を伴うものが互いに何が異なるのかに注目する。米国におけるイノベーションの競争は、地域の特許取得の実績で測られるが、それが搾取的か探索的かは、後方引用の程度で区別されている。2つの集積外部性を含む拡張した知識‐生産関数から、産業セクターに関係なく、多様化した外部性には探索と搾取のいずれにも正の関連性があるが、特化的外部性は搾取と関連していることが示される。
