Empirical study on green development of marine economy driven by marine scientific and technological innovation and its influencing factors

Summary: This paper examines the impact of the digital economy on innovation and analyzes it from various aspects such as elements, tools, subjects, and environment of innovation. The study constructs a development level index system for the digital economy and analyzes the temporal and spatial development in China. Additionally, the nonlinear impact of the digital economy on innovation, known as the threshold effect, is also studied. The research reveals that China's digital economy is rapidly developing, but there is a spatial imbalance and significant differences across different dimensions. Moreover, the impact of the digital economy on innovation exhibits both double threshold effects and single threshold effects.

Summary: This study analyzed the interaction among marine S&T innovation, marine finance, and marine higher education, and constructed a marine S&T innovation finance-higher education composite system. The results showed that the coupling and coordination level of the marine composite system improved overall, but there were significant differences among provinces and cities.
