Research On Structural Characteristics Of The International Trade Network Of Wind Power Equipment

In recent years,environment pollution,resource depletion and other issues caused by the use of fossil energy highlight gradually,a great deal of countries gradually turn to the utilization of renewable energy.Wind energy is widely used in the world because of its easy availability and efficient forms of energy utilization.As a major country in the utilization of wind energy,China has many wind power supporting projects,and occupies a very important position in the global wind power equipment industry.Therefore,based on social network theory,this article analyzes the structural characteristics of the global trade network of wind power products and the role of the main position of China in the network,in order to provide policy recommendations for the development of China’s wind power equipment manufacturing industry.On the basis of combing relevant literatures and analyzing theoretical concepts,this article uses the export trade data of global wind power products from 2001 to 2019 to study the structural evolution characteristics and community structure characteristics of the global trade network of wind power products.Firstly,the current situation of global wind power products in the world is analyzed.Secondly,the temporal trade network of global wind power products is constructed and the structural evolution characteristics of the trade network are explored from two aspects of overall structure and node degree.Based on this,the community structure of each product trade network is divided.Finally,based on the above analysis,two centrality indicators including closeness centrality and betweenness centrality are selected to estimate the status of China’s wind power equipment trade network and put forward corresponding policy suggestions.Based on the above research,this paper draws the following conclusions: Firstly,the export volume of wind power products is increasing year by year,the main export trade regions of them are Asia and Europe,among them,the export of wind power equipment components,gears and gear devices and roller bearings accounts for a relatively large proportion.Secondly,the global trade network of wind power products is increasingly complex,and its network density and network scale basically keep increasing year by year,showing the characteristics of a small world.Thirdly,the community structure of each product trade network is mostly centered on China,the United States and Germany,which rank first in node degree ranking.Next,as time goes on,China’s closeness centrality and betweenness centrality in the network rank first among the leading countries,which indicates that China occupies a solid core leadership position in the global trade network of wind power products.Finally,the paper puts forward policy suggestions to promote China’s trade status of wind power equipment from the aspects of deepening global trade cooperation,promoting the coordinated development of import and export trade,strengthening infrastructure construction,playing a core leading role,and improving relevant wind power policies.
