Digital platform-based ecosystem has gradually become an effective way for firms to achieve competitive advantage in the digital economy era. It identified key scientific issues and illustrated future avenues for digital platform-based ecosystem research in the domain of management from three aspects： theoretical perspectives， research methods， and research contexts. First， it introduced key scientific issues from six theoretical perspectives， including resource orchestration， dynamic capabilities， problem-solving， paradox， socio-technical systems， and digital platform-based ecosystem. Second， it expanded the application of digital platform-based ecosystems within research contexts such as new quality productive forces， the industrial internet， and the perspective of Chinese path to modernization. Finally， it summarized research priorities from the methodological perspective， which include： using simulation techniques to study the evolutionary mechanisms and dynamics of digital platform-based ecosystems； applying econometric analysis methods to advance research on the industrial internet； employing data mining techniques to conduct micro-level studies based on large-scale user data； and utilizing case studies to investigate mechanisms across diverse digital platform-based ecosystem scenarios.
