  1. 1. The pace of innovation : Patterns of innovation in the cardiac pacemaker industry

    Författare :Patrik Hidefjäll; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Cardiac Pacemaker; Competition; Competitive Advantage; Defibrillator; Dominant Design; Innovation; Organizational Field; Patterns of Innovation; Technical Change; Technology Cycle; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Sammanfattning : The PhD thesis "The Pace of Innovation" addresses the questions how patterns of innovation change over time in an industry, their consequences for competition and how institutional conditions in an industry shape determinants of patterns of innovation. Patterns of innovation mainly refer to how certain regularities in the diversity, types and locus of innovation change in an industry according to a technology and industry life cycle. LÄS MER
