The purpose of this study was to find out the progress in the research of technology ecosystems and digital business ecosystems and to combine that information for business purposes by the utilization of information about business ecosystems. The need for this information emerged at the Department of Information Processing Science in the context of European Union research projects. The information gained is expected to assist to increase possibilities both for the research and for the personal competence to work with enterprises in new kinds of technology environments. The main research question to be answered in this study was: How are technology ecosystems and digital business ecosystems for business perceived and approached in the literature? Instead of a systematic review, a method of systematic mapping was selected to structure the selected research areas for getting a broad overview over the two streams of research, and for identification the possible research evidence. To answer the main question the following subquestions were set for both systematic mapping studies: RQ1 Which journals include papers on technology ecosystems / digital business ecosystems for business? RQ2 What are the most investigated topics of technology ecosystems / digital business ecosystems and how have these changed over time? RQ3 What are the most frequently applied research approaches and methods, and in what study context? Based on structuring the selected research areas according to the set subquestions, broad overviews were established presenting findings. Based on the identification and evaluation of publication channels the forums for discussion were exposed. Based on the identification of topics and their evolution the trends of discussion were exposed. Based on the identification of research types the non-empirical and the empirical research were exposed. Found research evidence and found solution proposals (from non-empirical research) were discussed and the need for further research was considered. The main contribution of this mapping study was the identification of different perceptions of two vague concepts, technology ecosystem and digital business ecosystem, and notion of their convergence and interlace over time (especially in relation to the exposed scarce research evidence). The recommendations for future research were set based on the found empirical research and solution proposals, as well as limitations of this study.
