【行业深度】洞察2025：中国功率半导体行业竞争格局及市场份额（附竞争梯队、市场集中度、企业竞争力分析等）

Core Insights - The Chinese power semiconductor market exhibits a pyramid structure, with international large semiconductor companies in the first tier, domestic leading companies with IDM capabilities in the second tier, and specialized manufacturing companies in the third tier [1][6]. Market Share - In 2024, the market share of domestic companies in the Chinese power semiconductor industry shows that Wentai Technology exceeds 10%, Silan Micro exceeds 5%, and Huazhong Micro, Yangjie Technology, and Zhenhua Technology exceed 3%. Companies like Sinda Semiconductor, Jiejie Microelectronics, Huami Electronics, and Xinjie Energy have market shares above 1%, while others are below 1% [5]. Market Concentration - The concentration ratios for the Chinese power semiconductor industry in 2024 are CR3 at 25%, CR5 at 31.3%, and CR10 at 37.5%, indicating a competitive market with many participants. Although leading companies hold significant shares, the advantages are not pronounced, allowing opportunities for smaller firms [6]. Strategic Layout - Key companies like Times Electric and BYD Semiconductor have effectively implemented integrated strategies, particularly in the rail transit and automotive sectors, enhancing their influence in the supply chain. Sinda Semiconductor focuses on upstream raw materials, investing 229 million yuan in a silicon carbide module project. Huazhong Micro's acquisition of Runxin Microelectronics in 2022 bolsters its capabilities in GaN power devices [10][11]. Competitive Landscape - Analyzing the competitive state through Porter's Five Forces model reveals that the upstream supply capability is limited with high customization, giving suppliers strong bargaining power. The demand for power semiconductors is substantial, but buyers have weak bargaining power. The industry is attractive for potential entrants, though high barriers exist in terms of capital, technology, and talent. The threat from substitutes is low, and competition among existing players is moderate [14].
