Opportunities and challenges coexist Continental sensor industry faces new development


In recent years, through the introduction and transformation of technologies, China's sensitive components and sensors have formed a certain industrial base and production capacity. Five new sensors such as MEMS have been listed as research and development priorities. According to statistics compiled by the China Electronics Manufacturers' Directory from 2006 to 2007 compiled by the Institute of Science and Technology Information of the Ministry of Information Industry, there are currently 455 manufacturers engaged in the production of sensitive components and sensors in mainland China, and as many as 1,400 companies are involved, showing good results. There are fewer backbone enterprises with stronger development momentum but stronger overall strength. At present, products that can be mass-produced involve seven categories of light-sensitive, voltage-sensitive, heat-sensitive, force-sensitive, gas-sensitive, magnetic-sensitive, and moisture-sensitive, and about 3,000 varieties. According to the statistics of China Electronic Components Association, the total sales revenue of sensor products in mainland China in 2006 was RMB 9.743 billion, an increase of 12.2% year-on-year.

The compound annual growth rate from 2004 to 2006 was 11.3%. In 2006, the export value was US$658 million, which accounted for 55.8% of the total sales, which was an increase of 8.7% compared with 2005 (see Table 1).

In recent years, with the rapid growth of the production of automobiles, communications, industrial control, consumer electronics and special equipment, the demand for sensitive components and sensors has grown at the same pace. Due to the large gap between the technology and production capacity and the developed countries, the low level of product technology, and the incomplete specifications, China's sensor products are still far from meeting domestic demand, especially some high-grade sensors, MEMS sensors, and automotive sensors. As well as dedicated sensors, etc., mainly rely on imports.

According to statistics, the imports of sensitive components and sensors from mainland China rose rapidly from 1.426 billion U.S. dollars in 2004 to 2.372 billion U.S. dollars in 2006, with a compound growth rate of 29%. What is more serious is that the share of imports in the domestic market has risen from 76.7% in 2004 to 80.9% in 2006, and will further expand in 2007 (see Figure 1).

At present, sensor technology is moving toward the direction of intelligence, miniaturization, low power consumption, wireless transmission, and portability. The demand for domestic sensor applications continues to grow at a high rate. Under the fierce competitive environment that international sensor giants have entered, the sensor industry in mainland China is undergoing Facing new development opportunities and challenges.
