· Competitive Landscape of China's Switching Power Supply Industry in 2024

Taiwan funded enterprises represented by DELTA, MEAN WELL, LITEON, etc. have a competitive advantage in the field of switching power supplies with advanced technology and high value-added products. Since switching power supply enterprises in Chinese Mainland started late, they are insufficient in R&D ability, manufacturing level and service response ability compared with world-class enterprises.Due to the low technological content and added value of their products, many enterprises compete fiercely in the mid to low-end product market, resulting in lower overall market concentration. In recent years, with years of technological accumulation, excellent domestic power supply enterprises have continuously achieved breakthroughs in product independent research and development capabilities and production process levels, which can meet the needs of customers for new products and processes. China has gradually become the main production base for switch power supplies worldwide.Some leadi...
