Research on the Construction of Marine Development Framework Model and the Mechanism of Dynamic Elements Based on System Dynamics

Abstract

Li, H. and Xue, W., 2020. Research on the construction of marine development framework model and the mechanism of dynamic elements based on system dynamics. 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. 131–134. Coconut Creek (Florida), ISSN 0749-0208.From the perspective of system dynamics, this article constructs the dynamic system framework of marine development, and uses Cobb Douglas production function for reference to explore the dynamic mechanism and characteristics of marine resources, capital, labor force, science and technology, and other factors to promote marine development under the condition of technological nonneutrality. On this basis, the dynamic model of marine development is constructed, and the panel data of China's coastal areas in 2000–2019 are used for empirical tests. The main conclusions are as follows: the positive driving effect of capital on marine development is the most significant, followed by investment in science and technology, the positive effect of the labor force is not significant, and the negative effect of marine resources is not obvious. In accordance with the research findings, an improvement path of marine development power mechanism is proposed from the perspectives of industrial structure and layout, finance, marine science and technology, and its achievements: transformation, regional cooperation, integration of land and sea, and infrastructure.
