Integration Relationship and Dynamic Interaction Effect Between Marine Science and Technology and Green Development in China
Based on the connotation definition of the marine science and technology and marine green development and their integration mechanism analysis,this paper uses the improved TOPSIS model to measure the composite indexes of the marine science and technology and the marine green development in 11 provincial-level regions.It analyzes the integration effect of the marine science and technology and the marine green development and their dynamic relationship by the means of the coordinated development degree model and the PVAR model.The results show that:1)The level of the marine science and technology keeps rising,Shandong,Shanghai and Guangdong become the cores of the marine science and technology development in the north,east and south directions.The level of marine green development fluctuates and rises,showing obvious spatial differentiation.2)The degree of integration and coordination between the marine science and technology and the marine green development is increasing continuously at the provincial level in China.Combined with the types of the integration coordination,it shows the spatial evolution pattern of the echelon changes in 11provincial-level regions,showing the spatial evolution pattern of the echelon change of the northern marine economic circle＞the eastern marine economic circle＞the southern marine economic circle.3)There is no causal relationship between the marine science and technology innovation and the marine green development in the northern marine economic circle.It exists bidirectional causality between the marine science and technology innovation and the marine green development in the eastern marine economic circle and southern marine economic circle.The marine green development presents significant positive on the marine science and technology,the marine science and technology has long-term,continuous,fluctuating and lagging impact on the marine green development,but the marine green development plays more important role overall,it has quite different in the impact effect between the eastern marine economic circle and the southern marine economic circle.
