Economic geography is an important subject for policymakers when it comes to technological change and as development of Industry 4.0 is an important topic, the subject will only increase in importance. The purpose of the study was to map and analyse the spatial distribution of Industry 4.0 innovation activity in Sweden from 2017 to 2023 with the objective to find major innovation hubs and construct a patent dataset representing Industry 4.0 innovation. Earlier research suggested that the innovative activity should be clustered around the major metropolitan areas as they possess the necessary externalities. Theory further suggests that outliers in the data can be found in proximity to nearby universities or firms with high R&D investment. The findings show that the distribution mostly follows the expected pattern with some localised innovation hubs depending on the analysed variable. Policymakers can use these findings to understand the spatial properties of Industry 4.0 to make regional policies more effective.
