5. 4. An inquiry into the nature and causes of digital platforms

   Författare :Ted Saarikko; Katrin Jonsson; Jonny Holmström; Panos Constantinides; Umeå universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Digital platform; platform strategy; platform development; stability; affordance theory; qualitative study; data- och systemvetenskap; computer and systems sciences;

   Sammanfattning : While the shape and nature of platforms varies across different instances, they pursue common ambitions such as reduction of risk, complexity, or transaction costs. Although initially theorised in industrial contexts, subsequent theorising regarding platform development, platform ecosystems, and platform strategy has drawn upon studies of high-tech industries in general and IT-based platforms in particular.
