The development of polysilicon industry is an important mission of domestic industry. China's semiconductor industry, photovoltaic industry development and even the development of the national defense industry are inseparable from China's own polysilicon industry. The solar photovoltaic industry is an important component of strategic emerging industries and an important guarantee for realizing China's energy structure transformation, tackling climate change, and achieving emission reduction targets. As the basic raw material for solar photovoltaic power generation, polysilicon has important strategic significance for its healthy development. It has been regarded as an important strategic material by developed countries such as the United States and Japan. It is the rapid development and growth of China's polysilicon industry that has supported China's solar cell production ranking first in the world for five consecutive years. Today, the slowdown in demand growth in foreign markets, the intensification of competition in domestic and foreign markets, and deep-seated contradictions within the industry have once again placed China's polysilicon industry at the threshold of opportunities and challenges. China's polysilicon industry urgently needs to improve its industrial structure, promote industrial support, and enhance its core competitiveness in terms of scale and cost. China's polysilicon production has accounted for about 35% of the world's total. At the end of 2012, China's polysilicon production capacity will reach 200,000 tons. In 2011, on the one hand, due to the impact of the European debt crisis, the major markets for photovoltaic products, European countries, drastically reduced policy subsidies, which caused the photovoltaic industry to be greatly impacted; on the other hand, during the first half of 2010-2011, The investment in the photovoltaic industry has been increasing, and the production capacity has been greatly expanded, which has made the global solar cell product inventory pressure more prominent. The photovoltaic industry has entered a new round of adjustment period, and the domestic polysilicon industry is also deeply affected by this. In 2011, with the release of new and expanded production capacity of polysilicon enterprises, global polysilicon production continued to grow. In 2011, the global total output reached 240,000 tons, an increase of 30% compared with 2010. It is expected that there will still be a growth of around 30% in 2012. Globally, the supply and demand of polysilicon market is basically balanced or slightly larger than demand. Driven by the development of the photovoltaic industry, China's domestic demand for polysilicon is also increasing year by year. From the consumption of 16,544 tons in 2008, it increased to 146,131 tons in 2011. According to the latest survey of China Electronic Materials Industry Association, domestic polysilicon production reached 82,768 tons in 2011, an increase of 84% from 45021 tons in 2010. The industry still maintains a rapid growth momentum. From 2006 to 2011, China's polysilicon production has increased several times, with an average annual growth rate of more than 100%. In 2011, the annual sales exceeded 23 billion yuan, basically the same as in 2010; the total number of employees exceeded 15,000, including more than 5,000 technicians. As of the end of 2011, the total production capacity of polysilicon production lines in China has reached 148,000 tons. It is estimated that by the end of 2012, China's polysilicon production capacity will reach 200,000 tons. China's polysilicon production has accounted for about 35% of the world, and has become a global polysilicon production country after the United States and Germany. In recent years, domestic polysilicon production enterprises have achieved rapid development and have broken the international polysilicon production pattern. Some enterprises in China, such as Jiangsu Zhongneng, Saiwei LDK, Luoyang Zhongsi and Chongqing Daquan, have reached the forefront of the world in terms of production capacity. Jiangsu Zhongneng has become the world's third largest polysilicon producer with annual production of nearly 30,000 tons and a capacity of 46,000 tons. Its polysilicon production accounts for 36% of total domestic production. The annual output of LDK has also exceeded 10,000 tons.
