Core Viewpoint - The article emphasizes the importance of observing industrial concentration at both regional and industry levels to avoid "involution" and promote healthy industrial development [2][4]. Regional Perspective: Core Industries of Each Province - The average revenue share of the top-ranked industry in 30 provinces is 19.7%, with notable provinces exceeding 20%: Jilin (42.3% in automotive), Shanxi (38.7% in coal mining), Hebei (29.6% in black metal smelting), Beijing (28.4% in electric heat), Guangdong (25.7% in electronic equipment manufacturing), Hainan (25.6% in fuel processing), Shanghai (20.9% in automotive), Inner Mongolia (20.7% in coal mining), and Chongqing (20.6% in electronic equipment manufacturing [4][10]. - The combined revenue share of the top five industries in each province averages 54.9%, with higher concentrations in provinces like Hainan (66.4%), Shanxi (71.7%), Beijing (70.6%), Jilin (69.3%), Ningxia (67%), and Qinghai (79.5%) [4][10]. Industry Perspective: Advantageous Regions for Each Industry - The top five provinces in terms of industrial revenue account for 47.4% of the national industrial revenue, with Guangdong, Jiangsu, Zhejiang, Shandong, and Fujian being the largest [5][13]. - The average concentration of the top five industries across 41 sectors is 59.7%, with lower concentrations observed in sectors such as non-ferrous metal mining, food processing, and pharmaceutical manufacturing [5][13]. - In the midstream equipment manufacturing sector, notable concentration levels include electrical machinery (66.2%), electronic equipment (63.1%), and instruments (68.8%) [5][13]. Industry Presence Across Provinces - Eight industries, including electric heat, electronic equipment, and automotive, rank among the top five in revenue across more than ten provinces, indicating significant investment in these sectors [6][14]. - Conversely, industries like pharmaceutical manufacturing and specialized equipment manufacturing are only ranked in the top five in a limited number of provinces, highlighting potential areas for growth or investment [6][14].
