Summary. China holds the world's largest number of photovoltaic technology patents, but lacks core technologies limiting further innovation. This study analyzes 20 years of PV patent data using social network analysis to map China's innovation structure. Leading enterprises have formed stable collaborations, with innovation concentrated in eastern coastal provinces. Cross-regional collaboration has grown significantly, centered on three major hubs: the Yangtze River Delta, Pearl River Delta, and Beijing-Tianjin-Hebei region.
