This article studies the link between technical and management innovation. Two types of technical innovation are identified: product and process innovation. The effect of the size of the firm is also taken into account. We presume that the more innovative a firm is in products and processes, the more innovative it will be in management. We also presume that firm size has an effect on the link between technical and management innovation. We test these hypotheses on 20,542 companies in the French CIS database. To begin, the results show that product and process innovation are positively linked to management innovation. Secondly, the results also show that process innovation is more strongly linked to management innovation than product innovation. Thirdly, the results further demonstrate that the link between technical and management innovation is valid regardless of firm size and last, but not least, that the link between technical and management innovation is stronger for small firms.
