“…The empirical evidence that the local accumulation of knowledge (measured in terms of R&D expenditures, patents, innovation counts or questionnaire results) spurs firms’ productivity and growth is abundant (Cassia, Colombelli, & Paleari, ; Geenhuizen & Reyes‐Gonzalez, ; Gilbert, McDougall, & Audretsch, ). In particular, recent firm‐level studies (e.g., Cecere & Mazzanti, ; Horbach & Janser, ; Kunapatarawong & Martinez‐Ros, ; Leoncini, Marzucchi, Montresor, Rentocchini, & Rizzo, ) have shown that green innovation is particularly conducive to employment growth by favouring cost‐saving and pushing labour‐absorbing investment. Accordingly, the size of local green investment projects can be considered as a good proxy of the local sensitiveness to the environment, which in turn captures the incentives to labour‐absorbing, green investment.…”
