中观产业研究系列之一：“反内卷”与集群化：区域比较优势如何支撑产业升级？

Group 1: Regional Comparative Advantage - The concept of regional comparative advantage is crucial for determining industrial layout efficiency and economic growth quality during the transition phase of industrial structure upgrading[6] - In 2026, 29 out of 31 provinces emphasized the importance of establishing a correct performance view, reflecting a shift towards long-term high-quality development[7] - Traditional industries are continuing to advance in cluster development based on comparative advantages, while emerging industries seek breakthroughs[11] Group 2: Key Industry Advantages - The "location quotient" (LQ) is used to analyze regional advantages, with provinces like Guangdong, Jiangsu, Shandong, and Zhejiang being key economic players due to their comprehensive industrial systems[15] - In the semiconductor industry, regions like Beijing-Tianjin-Hebei, Shanghai, Anhui, and Shaanxi have been included in the national integrated circuit industry cluster list, indicating strong regional advantages[24] - The photovoltaic equipment industry is exemplified by Jiangsu and Xinjiang, which have achieved high concentration in both quantity and revenue, forming a complete industrial cluster system[34] Group 3: Industry Concentration and Profitability - Industry concentration and profitability are not always positively correlated; for example, while the household appliance and chemical pharmaceutical industries show rising concentration and profitability, the IT services and military electronics sectors face declining profitability despite increased concentration[36] - The semiconductor industry is currently in a growth phase, with profitability improving, while the components industry shows resilience with a slight decline in concentration but recovery in profit margins[41] - The electrical equipment and electronic chemicals sectors are experiencing a decline in both concentration and profitability, indicating a period of industry turmoil and potential restructuring[46]
