Zhu, F., 2020. Evaluating the coupling coordination degree of green finance and marine eco-environment based on AHP and grey system theory. In: Al-Tarawneh, O. and Megahed, A. (eds.), Recent Developments of Port, Marine, and Ocean Engineering. Journal of Coastal Research, Special Issue No. 110, pp. 277–281. Coconut Creek (Florida), ISSN 0749-0208.The authors attempt to study the coupling coordination degree (CCD) between green finance and marine ecoenvironment. To this end, it constructs a composite evaluation index system of green finance and marine ecoenvironment based on the domestic and foreign literatures, and then evaluates the comprehensive development level of the two systems using the combination method of analytic hierarchy process (AHP) and grey system theory. Meanwhile, the coupling degree model, and model were introduced to measure the coupling degree, CCD and comprehensive coordination index of China's green finance and marine eco-environment. The results showed that as China gradually began to attach importance to green development, the coupling coordination between green finance and the marine eco-environment system are both slowly increasing. The research findings provide a scientific basis for the practice of green finance and marine sustainable development in China.
