The semiconductor industry is a symbol of modern science and technology. With the rapid development of modern science and technology industry in recent decades, the market scale of semiconductor industry based on integrated circuit (IC) is growing, and it has become an important pillar of the global economy. According to the world trade Semiconductor Association (WSTS) statistics, the global semiconductor industry market reached $304 billion 300 million in 2013, breaking through the 300 billion dollar mark for the first time, up 4.4% from $291 billion 600 million in 2012. This is also the resumption of positive growth in the semiconductor industry after two years of weakness in 2011 and 2012.

The semiconductor industry is at the top of the whole electronic industry chain, and it is also the most influential industry in the electronic industry. The output growth of the semiconductor industry is highly correlated with the growth rate of the global GDP, and the overall periodicity is more significant.

Semiconductor industry has a wide range of products and is widely used in all walks of life. The products mainly include four categories: integrated circuits, discrete devices, optoelectronic devices and sensors. Among them, IC is the core of the whole semiconductor industry, and can be further divided into four sub fields: microprocessor, logic IC, memory and analog circuit.

In 2013, the scale of global integrated circuits, discrete devices, optoelectronic devices and sensors was 250 billion 700 million, 18 billion 200 million, 27 billion 500 million and 8 billion, respectively, and accounted for 82%, 6%, 9% and 3%, respectively. In the IC industry, microprocessors, logical IC, memory, and analog circuits are 58 billion 700 million, 84 billion 800 million, 67 billion 300 million, and $39 billion 900 million, respectively, accounting for 19%, 28%, 22% and 13% of the semiconductor industry.

China's semiconductor industry generally started late and the base was relatively low. However, with the dual impetus of human cost advantage and policy dividend, the overseas semiconductor plants have come to the mainland to invest and build factories, while the local manufacturers are rising rapidly, and the Chinese mainland semiconductor industry is growing rapidly.

According to the statistics of China Semiconductor Association (CSIA), the scale of semiconductor industry in mainland China in 2013 was 397 billion 400 million yuan, up 12% from 354 billion 800 million yuan in 2012. Over the past ten years, the annual growth rate of China's semiconductor industry has been 19.2%, significantly higher than that of the global 6.2%.

With the rapid development of China's semiconductor industry, the regional structure of the global semiconductor industry has undergone tremendous changes. China's semiconductor industry has risen by 8 percentage points in the past five years, up from 18% in 2008 to 26% in 2013. As a global industry leader, the U.S. semiconductor industry has also increased the market ratio, up 5 percentage points to 20% in the past five years. Japan's semiconductor industry showed a declining trend, from 20% in 2008 to 11% in 2013.

As a typical cyclical industry, semiconductor is basically consistent with the global macro economy. The Philadelphia Semiconductor Index, the world's most important semiconductor industry index, has rebounded from a minimum of 167 points at the end of 2008 to close to 650, more than the high point in 2007, and a high number of innovations in the near future. The Taiwan Semiconductor Index has also recently risen to 125, more than the high point in 2007, and has also created a new high in history, further proving that the global semiconductor industry is at a high level.
