Li, X.; Wang, M.; Chi, J.F., and Yang, X.M., 2020. Policy effects and suggestions on green technology innovation of marine enterprises in China. 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. 76–79. Coconut Creek (Florida), ISSN 0749-0208.

Based on the survey of enterprises in Beijing, Guangzhou, Wuhan, Jinan and other regions, this study used OLS regression analysis to verify the impact of green technology innovation policy on enterprises' green technology innovation benefits. The results show that only the voluntary agreement tool has a significant positive effect on the environmental performance of enterprises' green technology innovation, and effects of other policies on the green technology innovation benefits of enterprises are not significant. Finally, some policy suggestions are put forward to promote the green technology innovation of marine enterprises.
