China’s Coal Domestic Trade Pattern And Influencing Factors And Its Relation With Economic Growth

The status of China’s coal as the main energy source is difficult to change in the short term,and too large coal imports are not conducive to the healthy development of China’s coal domestic trade.This paper studies the domestic trade pattern of China’s coal,on the basis of which it studies the factors affecting the scale of China’s coal domestic trade,and further studies the combination of China’s coal domestic trade and economic growth.Based on this,it puts forward policy recommendations that are in line with the development of China’s coal domestic trade,which are conducive to promoting the development of China’s coal domestic trade and ensuring China’s energy security.On the basis of understanding the current situation of China’s coal resources,this paper constructs a directed weighted network model of China’s coal domestic trade by using the method of complex network,and analyzes the overall index of China’s coal domestic trade network,the individual index of the network and the division of network associations in combination with the relevant indexes of complex network.The results show that the trade links among the provinces in China’s coal domestic trade network tend to be equalized gradually,the overall network system is relatively uniform,and the trade relations show diversified characteristics.Among them,the "three western" regions occupy an important position in China’s coal trade network.In addition,the trade relations among the provinces in the trade network are relatively close,and most regions often have trade relations with regions with similar geographical locations.After understanding China’s coal domestic trade pattern,this paper uses VAR model to make regression analysis on the factors affecting China’s coal domestic trade scale,including China’s coal import scale,China’s transportation capacity,China’s coal technological innovation and environmental regulation.The regression results show that there is a long-term stable cointegration relationship between China’s transportation capacity,China’s coal technological innovation and China’s coal domestic trade scale in the same direction,and there is a long-term stable cointegration relationship between China’s coal import scale,environmental regulation and China’s coal domestic trade scale in the opposite direction.In addition,this paper studies the combination of China’s coal domestic trade and economic growth,and calculates the grey correlation coefficient between China’s coal trade and GDP and the grey correlation coefficient between coal trade and regional GDP in various provinces by using the grey correlation analysis method.The results show that coal trade is more to drive regional economic growth.The grey correlation degree between coal import and local GDP in Inner Mongolia Autonomous Region,Xinjiang Uygur Autonomous Region,Shaanxi Province,Ningxia Hui Autonomous Region and Shanxi Province is larger,while the grey correlation degree between coal import and local GDP in Liaoning Province,Hebei Province,Anhui Province and Henan Province is larger.Therefore,in the future,we can give full play to the leading role of the "three western" regions in China’s coal domestic trade,continuously optimize the coal transportation structure,improve the utilization rate of coal resources and actively promote the energy transformation,thus promoting China’s economic transformation.
