Electronic commerce is one of the technological tools that emerge as a response to the globalization phenomenon and society's high demand for more competitive companies. Many studies have addressed e-commerce from multiple perspectives and approaches. This study examines the field of electronic commerce knowledge through a bibliometric analysis, mainly embracing technology diffusion, adoption, and acceptance of a Scopus database comprising 226 articles from 2000 to 2020. To analyze the data, we used quality indicators, scientific impact, and structural elements. The results show that, although there is progress in research on electronic commerce, many of the issues addressed and methodologies used are still the objects of study in different countries.
