There are more than 1700 enterprises engaged in the production and research of intelligent sensors in China, of which more than 50 are engaged in the development and production of micro-systems. At the same time, smart sensors are more and more applied to various fields of social development and human life. Such as industrial automation, agricultural modernization, aerospace technology, military engineering, robotics technology, resource development, ocean exploration, environmental monitoring, security, medical diagnosis, transportation, household appliances and so on.

At present, the production enterprises of smart sensors in China are mainly concentrated in the Yangtze River Delta region, and gradually form a regional spatial layout with Beijing, Shanghai, Nanjing, Shenzhen, Shenyang and Xi'an as the main cities. With the rapid development of Internet of Things, mobile Internet and other emerging industries, smart sensor industry has also ushered in a huge opportunity for development. In recent years, the domestic smart sensor market continues to grow rapidly, with an average annual growth rate of more than 20%. Since 2015, with the continuous emergence of intelligent electronic products and the steady development of the Internet of Things (IOT) intelligent terminal and whole machine manufacturing market, the demand for localization of intelligent sensor products has been increasing, which has brought tremendous development space for domestic enterprises. Research and development and industrialization of autonomous MEMS intelligent sensor products have become the main direction of industrial development. Driven by the rapid development of the Internet of Things, the market scale of smart sensors is also showing a rapid development trend. In the next five years, the annual composite growth rate of China's smart sensor market will reach about 30%.

With the intensification of market competition, the mergers and acquisitions of smart sensor industry are increasing. Foreign large-scale smart sensor enterprises have formed their own technological advantages through mergers and acquisitions. The mergers and acquisitions of domestic smart sensor enterprises, such as Geer Acoustics, Aerospace Electronics, Dongfeng Science and Technology, have begun to strengthen their competitiveness through mergers and acquisitions. In the future, the formation of domestic smart sensor leading enterprises will greatly enhance the competitiveness of industry and promote the healthy development of industry.

I. Overview of the Development of Intelligent Sensor Industry

China's smart sensor market has been growing steadily in recent years, with a growth rate of more than 20%. The four major areas of smart sensor applications are industrial and automotive electronics, communications electronics and consumer electronics.

Since 2012, the overall scale of development of China's smart sensor industry has gradually expanded. It has been significantly applied in the automotive industry, including the application of smart sensors in automotive tires, the application of smart sensors in airbags, the application of smart sensors in chassis system, the application of smart sensors in engine operation management system, and the smart sensors in exhaust air and air quality control system. Use and demand, application and demand of intelligent sensor in ABS, application and demand of intelligent sensor in vehicle driving safety system, application and demand of intelligent sensor in automobile anti-theft system, application and demand of intelligent sensor in engine combustion control system, application and demand of intelligent sensor in automobile positioning system, application and demand of intelligent sensor in other automobile systems Demand.

In addition, smart sensors in China also have new applications in other fields, such as industrial control, environmental protection, facility agriculture, multimedia image, and other related smart sensors. Looking back on China's smart sensor industry, although it has developed rapidly, there are also some unfavorable factors. For example, in terms of product technology, the industry foundation is weak, science and technology are out of touch with production, product technology level is low, product types are insufficient, and enterprise product research and development ability is weak.

However, on the other hand, the state has been formulating strategies and policies that are conducive to the development of smart sensor industry. The rapid development of the whole system market and the constant promotion of emerging technologies have also become favorable factors for the development of sensor networks throughout the year.

II. Present Situation of Enterprises in Intelligent Sensor Industry

With the support of the government, great progress has been made in sensor technology and its industry in China. Under the guideline of "double-processing process": speeding up the development, the domestic sensor industry has established the production base of sensitive components and sensors in China.

At present, there are three major sensor production bases in China, namely: Anhui base is mainly to build power and light-sensitive economies of scale; Shaanxi base established Shaanxi Sensitive Technology Industry Group Company in February 1990, mainly to establish voltage-sensitive, heat-sensitive, automotive electronic economies of scale as the main objective; Heilongjiang base is mainly to establish gas and humidity-sensitive economies of scale as the main objective.

At present, there are more than 1700 enterprises engaged in the production and research of sensors in China, of which more than 50 are engaged in the development and production of microsystems. At the same time, sensors are more and more applied to various fields of social development and human life, such as industrial automation, agricultural modernization, aerospace technology, military engineering, robotics technology, resource development, ocean exploration, environmental monitoring, security, medical diagnosis, transportation, household appliances and so on.

According to statistics, by 2015, the overall market size of the Internet of Things in China will reach 750 billion yuan, from which the sensor industry will benefit directly. It is predicted that the sensor market in China will develop steadily and rapidly in the next five years. Under the impetus of the large-scale growth of the Internet of Things market, the capacity of the sensor market in China is expected to reach about 170 billion yuan in 2016.

III. Analysis of Supply Situation of Intelligent Sensor Industry

By the end of 2015, there are more than 1700 enterprises and institutions engaged in the development, production and application of sensors in China. There are more than 50 enterprises engaged in the development and production of micro-systems. There are more than 6000 kinds of products. It is estimated that the output of smart sensors will reach 3.16 billion in 2016. However, about 70% of the small sensor enterprises in our country have low-end products, and high-end products account for a large proportion of imports. Among them, about 60% are sensors, 80% are sensor chips, and almost 100% are micro-electronics chips.

At present, there are about 1700 enterprises engaged in the development, production and application of sensors in China. Industry categories are basically complete. The total annual output of sensors and sensors is close to 3 billion. Sensor products reach 10 categories, 42 categories and more than 6,000 varieties.

According to incomplete statistics, the national sensor sales in 2015 were close to 140 billion yuan. However, most of them still have serious shortcomings of digital, intelligent and miniaturized products.
