A plethora of studies has investigated the determinants of product innovation in small firms, suggesting product, firm, market and innovation process factors as its key drivers of success. Variations across industries relating to the determinants of product innovation are often suspected, but due to a lack of data this area is underresearched. In case of major differences much previous work will be flawed. Drawing upon of database of 1250 small firms across seven industries, this paper explores if any differences are found in the presence and impact of various firm-level determinants. Controlling for size and age differences, the analysis reveals some major differences to the extent small firms use innovative practices, and their connection with new product introductions.
