Modelling creative destruction: Technological diffusion and industrial structure change to 2050

Future disruptive, pervasive technologies will have important consequences for industrial structure, economic growth and the environment. Drawing on theories of technological diffusion, industrial evolution and long-term technological change this paper explores the effect of the development and diffusion of two future pervasive technologies on five industrial sectors in three regions during the 21st century in terms of their effect on economic structural change. Through semi-structured interviews with over 100 experts in the two technologies, the paper quantifies the effects of future biotechnologies and nanotechnologies on the industrial structure of the EU, USA and China in 2020 and 2050. The paper finds that as a result of the development and diffusion of future biotechnologies and nanotechnologies, some industries grow whilst others decline and some new ones emerge. The evidence suggests that the effect is different across countries and time; whereas the experts commonly believe that effect of the technologies on the industrial structure of the EU and US is likely to be similar, the effect in China is considered to be less by 2020 but the same as in the EU and US by 2050. This finding has important implications for the location of production, economic growth and energy demand in the future.
