One of the most significant results of the empirical literature on innovation studies of the 1980s and 1990s was that innovation patterns were characterized by important inter-sectoral differences. This finding prompted a lively research agenda that: i) provided empirical characterizations of sectoral patterns of innovation by means of taxonomic exercises; ii) sought to interpret sectoral patterns of innovation as emerging properties of underlying selection and learning processes reflecting the structural properties of technical change at sectoral level (“technological regimes”). In this paper, we reconsider one of the landmark works on technological regimes (e.g., Breschi et al. 2000), reassess its findings, and perform a quasi-replication of their its exercise. Our conclusion is that the proposed distinction between Schumpeterian patterns of innovation (Mark I vs. Mark II) and their interpretation in terms of technological regimes has still the promise of yielding important insights concerning on the connection between inventive activities and industrial dynamics.

1980 年代和 1990 年代创新研究的实证文献最重要的结果之一是，创新模式的特点是重要的部门间差异。这一发现引发了一个活跃的研究议程：i) 通过分类练习提供部门创新模式的实证特征；ii) 试图将创新的部门模式解释为潜在选择和学习过程的新兴特性，反映了部门层面技术变革的结构特性（“技术体制”）。在本文中，我们重新考虑了一项具有里程碑意义的技术制度（例如，Breschi 等人，2000 年），重新评估其发现，并对其练习进行了准复制。
