Shu, X., 2020. An empirical analysis for the promoting effect of marine economy on sustainable development of inland economy. In: Al-Tarawneh, O. and Megahed, A.

China has a long coastline. The rapid development of its marine economy has accelerated the interconnection of the ocean-inland industry and realized the development and docking of technology, talents, resources, and transportation. The authors aim to analyze the promoting effect of marine economy on inland economy. To this end, this paper first explores the driving mechanism of ocean-inland economic integration based on the theory of ocean-inland economic integration. Then, the Yangtze River Delta Economic Belt was selected as the research object to explore its role in promoting the sustainable development of inland economy. The study found that the integration of the marine economy and the inland economy can maximize the regional economic effect; the calculation results of the instantaneous rate of change in the economic magnitude from the Yangtze River Delta region to the inland region clearly indicate that the marginal effect of the Yangtze River Delta marine economic belt on the inland economy is also increasing year by year. Finally, a series of measures were proposed to promote the development of ocean-inland integration. The research findings provide a theoretical basis for the rapid and sustainable development of the inland economy.
