Some authors do not establish significant differences between these concepts. But others clearly differentiate them. Is there any intentional confusion?
My personal view is as follows: Industrial districts is a concept whichcould be considered more focuised in a geographically concentrated group of industriesn (North of Italy) .Clusters have a more sectoral specialization (i.e., furniture, terxtile, tile ceramic, shoes, orthopedics, phramaceuticals, etc.)
