Diffusion characteristics of private sector financed innovation in Sweden

Although construction is considered to be slow in adopting new technology and new processes, innovation, research and development are performed routinely. Nonetheless, knowledge about what affects the diffusion of research results—in the context of innovations—is incomplete, limiting the effectiveness of procedures designed to evaluate project proposals. The aim is to examine the factors that can influence the diffusion of results, in this case from externally funded construction innovation projects. A Fisher's exact test is performed on six concepts derived from general innovation theory which are tested on 20 development projects. The test is used to establish the significance of the six concepts and their applicability to construction-related innovation. The results reveal support for all six concepts, although only four of them attract a high level of significance. External lateral and vertical communication and external integration during the development phase are shown to increase the chances of successful diffusion and should therefore be assessed in project proposals.
