The goal of the Special Issue is to investigate how knowledge and trust can be developed, employed, diffused, and protected in business ecosystems, where data are the main asset for several actors. The issue contains six papers who have investigated these topics from different theoretical perspectives and by means of different methodological approaches. They represent an interesting combination of theoretical essays, research reviews and empirical studies. In addition, some of them focus on firms, some on consumers, and others on researchers who, like other actors today, need to find their way in the abundance of data and methodologies
