Like a dirt track, innovation can be radical, unconventional, adapted to human’s requirements, sometimes arising in a spontaneous order, and, most importantly, always evolving. This characteristic of continuous development fascinates scientists ever since and has led to a huge corpus of literature in the geography of innovation. But still, innovation always happens within the (edges of the) known, also depending on the paths that someone already took. Following Brenner and zu Jeddeloh (2023), those paths can be identified, categorized, and used to analyze systems that do not only depend on their history but also are reproduced, shaped, and created by human action. Given the complexity and diversity of today’s economic and innovation systems, further detailed analyses are still needed to improve our knowledge of path dependence in innovation processes and economic development.
