Purpose- The purpose of this article is to examine the potential of digital ecosystems in creating value and providing a competitive advantage for businesses and industries. Additionally, it aims to provide an understanding of how digital ecosystems function within a big data environment. Methodology- This study presents a general understanding of digital ecosystems and big data by reviewing previous research and literature. Focusing on two critical advantages of digital ecosystems in creating value and providing a competitive advantage, the analysis is conducted using example companies such as Amazon, Apple, and UBER. Findings- Digital ecosystems emerge as complex and dynamic structures that enable value creation processes and collaboration among technology, businesses, and users. These structures significantly differ from traditional collaborative ecosystems by relying on digital technologies and platforms for value creation processes. A successful digital ecosystem is based on three main elements: platform, network effects, and market expectations. Big data is considered one of the fundamental components of digital ecosystems and has the potential to increase their effectiveness and value. Conclusion- Digital ecosystems allow businesses and industries to increase their productivity, gain a competitive advantage, and achieve sustainable growth. In particular, big data analytics can be used to optimize the performance and decision-making processes of digital ecosystems. Examples such as Amazon, Apple, and UBER demonstrate the potential of digital ecosystems in creating value and providing a competitive advantage. Therefore, it is crucial for businesses to adopt digital transformation and innovation to benefit from the advantages offered by digital ecosystems.
