Abstract

This thesis aims to investigate the responses of the steel industry sector to the global carbon constraint (permits, taxes) and specifically the ULCOS (Ultra Low CO2 Steelmaking) technologies.The analysis relates more precisely to the conditions of the greening of innovations, the selection of new incremental and radical innovation and the inter-technology competition. It takes into account the uncertainty of the selection environment (evolution of the prices of energy, carbon, raw materials, steel demand, conditions of competition).The influence of the modification of the induced relative prices under different simulations is dealt with a partial equilibrium model.Complementary concepts of industrial economics and investment under uncertainty related to the decision, adoption and diffusion of technologies have been explored. I highlight the promising complementary work of integrating anticipation of actors and imperfect competition.The methodology developed is potentially useful for other sectors (industries of cement, paper, aluminium...). This case study on steelmaking illustrates the theoretical framework of the pluridisciplinary scientific agenda IHDP-Industrial Transformation that combines evolutionary and neoclassical economics of technical change.
