Abstract:The entropy value method, nuclear density method, and Gini coefficient analysis analysis of the high -quality development level and regional gap between China's strategic emerging industries. Studies have found that China's strategic emerging industries have a rise in high -quality development level, the largest contribution of industrial scale, followed by industrial benefits and industrial innovation, and finally financing for industries. From the perspective of the regional gap between the high -quality development level of strategic emerging industries, the overall level of the high -quality development of strategic emerging industries in the eastern region has greatly ahead of the central, western regions and northeast regions. The high -quality development level of strategic emerging industries in the central region has grown rapidly. The high -quality development of strategic emerging industries in the west and northeast regions has been at a relatively low level for a long time. From the perspective of provincial strategic emerging industries, China's strategic emerging industry's high -quality development level is three -level staircase. The Beijing -Tianjin -Hebei and the Yangtze River Delta urban agglomeration leads strategic emerging industries. The radiation effect of the Pearl River Delta region is weak. Based on this, the article puts forward suggestions for expanding the development of strategic emerging industries, improving industrial benefits, and strengthening the radiation role of strategic emerging industries in the Pearl River Delta region, in order to provide reference for the high -quality development of China's strategic emerging industries.
