2. 1. Västsvensk petroleumindustri 1945-2000 : etablering och tillväxt

   Author : Kurt Johnsson; Chalmers tekniska högskola; []
   Keywords : HUMANIORA; HUMANITIES; technological systems; petroleum industry; fuel refinery; innovation; institution; industrial network; petrochemicals;

   Abstract : The purpose of the study has been to describe and analyse the establishment and growth of the petroleum industry in western Sweden during the second half of the twentieth century. Empirical data shows that the development of refineries has in large part been governed by environmental changes where belonging to an international concern with large financial resources, and a determined investment in FoU in order to be at the forefront, has been advantageous.
