We explore the modelling of the determination of the level of R&D investment of firms. This means that we do not tackle the decision of being an innovator or not, nor the adoption of a new technology. We exclude these decisions and focus on the situations where firms invest in internal R&D in...

This paper focuses on the diversity of engine technologies for Low Emission Vehicles (LEVs) that are developed by car manufacturers in order to substitute for the conventional internal combustion engine vehicle. Our purpose is to analyse the competition between the various technologies for LEVs...

-->that the projects studied are in fact guided by a complex and variable structure of goals, in which environmental objectives are not always a priority. Our analysis shows that actors combine environmental and techno-economic objectives in some specific compromises.

This article presents an empirical and theoretical analysis of environmental innovations in an evolutionary framework. Such an evolutionary analysis enables us to develop a dynamic analysis of environmental innovations emphasizing their multidimensional character and their evolution along...

The purpose of this article is to discuss the contributions of the evolutionary theory of innovation on the micro and meso dynamics of environmental innovations. We argue that the evolutionary literature on innovation, and more particularly on technological regimes, provides a relevant framework...

This paper examines the usefulness of patent analysis for measuring eco-innovation. The overall conclusion is that patents are a useful means for measuring environmentally motivated innovations, such as pollution control technologies and green energy technologies, and for general purpose...

We explore the dynamics of environmental innovations developed by firms in order to comply with environmental regulations on the basis of a micro-simulation model of industrial dynamics. How do the firms competing in the same industry cope with the environmental dimension without altering their...

This paper explores the impact of diversity of innovative strategy of firms upon the industrial dynamics through a micro-simulation model. We consider two types of firms each one being characterised by a specific innovative strategy. Basically we assume that some cumulative firms adopt an...
