Chan Ye Xin Xi Wang·2025-06-04 01:30Core Viewpoint - The oxygen sensor industry in China is experiencing significant growth and technological advancements, driven by increasing demand in automotive emissions control, industrial applications, and emerging fields such as healthcare and smart manufacturing. The market size is projected to reach 20.901 billion yuan in 2024, with a year-on-year growth of 28.98% [1][11]. Industry Overview - Oxygen sensors are devices used to detect the oxygen content in gases or liquids, providing feedback signals to optimize system performance. They operate similarly to batteries, utilizing zirconia ceramics to generate measurable voltage signals through oxygen concentration differences [2]. Industry Development History - The development of the oxygen sensor industry in China has gone through three main stages: 1. Initial stage (1950s-1980s) focused on high-end applications with reliance on imports and limited domestic production capabilities [4]. 2. Technology introduction and independent research phase (1990s-early 2000s) where domestic companies began to absorb foreign technology and improve product quality [5]. 3. Rapid development phase (early 21st century) supported by national policies and increasing environmental requirements, leading to widespread applications in emissions control and industrial efficiency [5]. Industry Supply Chain - The upstream of the oxygen sensor industry includes raw materials such as zirconia, titanium dioxide, and precious metals, while the midstream involves the manufacturing of oxygen sensors. The downstream applications span automotive, industrial, healthcare, environmental monitoring, smart home, and aerospace sectors [7]. Market Size - The Chinese oxygen sensor market is expected to reach 20.901 billion yuan in 2024, with a significant increase in demand due to the implementation of the National VI emission standards and stricter environmental regulations in industries like steel and chemicals [11]. Key Companies' Performance - The competitive landscape of the oxygen sensor industry features international giants like Bosch and DENSO, alongside domestic players such as Anpeilong Technology and Sifang Optoelectronics. Anpeilong has achieved a full supply chain control in oxygen sensor production, while Sifang has made breakthroughs in nitrogen-oxygen sensor technology [12][17]. Industry Development Trends 1. Technological Upgrades and Smart Integration: The industry is moving towards smart, multifunctional oxygen sensors that integrate advanced technologies such as wireless transmission and self-diagnosis, enhancing operational efficiency and maintenance [19]. 2. Diversified Market Demand: The demand for oxygen sensors is diversifying across various sectors, including automotive, healthcare, and industrial applications, driven by the growth of electric vehicles and smart devices [21]. 3. Accelerated Domestic Substitution and Policy Support: The domestic substitution process is gaining momentum, supported by government policies that encourage the development of the sensor industry, reducing reliance on imports and enhancing the competitiveness of local companies [22].
