Sun, C., 2020. Digital finance, technology innovation, and marine ecological efficiency. In: Yang, D.F. and Wang, H. (eds.), Recent Advances in Marine Geology and Environmental Oceanography. Journal of Coastal Research, Special Issue No. 108, pp. 109–112. Coconut Creek (Florida), ISSN 0749-0208.
A growing consensus recognizes that finance and technology have important impacts on marine ecological efficiency. This paper first summarizes the tendency of marine green factor productivity by using the data envelopment analysis-Malmquist model. To understand the influence of digital finance on marine ecological efficiency, studying the data of coastal provinces in China from 2011 to 2018 provides an opportunity to discuss the theoretical relationship, where the effects of economic variables such as industrial structure and fiscal expenditure are well controlled. By using the fixed-effect model and instrument variables, the regression result shows that digital finance can promote marine ecological efficiency, which is more obvious in southern coastal provinces. In conclusion, it is important to strengthen the development of digital finance in coastal areas, encourage scientific and technological innovation, and promote ecological efficiency.
