Sustainability Assessment of Steel Industry in the Belt and Road Area Based on DPSIR Model

The steel industry in the Belt and Road region holds significant potential for development, systematic evaluation of its sustainable development capacity serves as a crucial foundation improving investment environment industry. This study focuses on driving forces, pressures, current status, impacts, policy responses industry, constructing an model region. Using this model, (SCSI) 65 countries along is assessed. results indicate following: (1) SCSI index has significantly increased from 18.050 2000 to 22.873 2021. (2) Since 2005, factors influencing spatial differentiation have generally followed pathway “industrial infrastructure → innovation global governance per capita GDP,” with domestic economic level demand exerting substantial promoting effect (3) regional differences within are combined result multiple factors, composite influences indicators such GDP, population size, industrial infrastructure, environment. To further enhance Road, it necessary each country formulate appropriate plans based local conditions, emphasizing strengthened international cooperation, optimized environment, enhanced support, improved technological
