China's plastic products industry also showed sustained and steady growth. In 2015, the output of China's plastic products was 75.657 million tons, a total increase of 1.0%. In 2016, the output of China's plastic products was 77.717 million tons, a total increase of 2.7%. From January to July 2017, among the industrial enterprises above designated size, the rubber and plastic products industry The main business revenue was 1.94177 trillion yuan, an increase of 9.7% over the same period of last year, with a profit of 112.140 billion yuan, an increase of 4.8% over the same period of last year. From January to July 2017, the output of primary form plastics in China was 49.95 million tons, a total increase of 4.2%.

    With the gradual transformation and upgrading of the industrial structure, the proportion of high-grade products has been gradually increased, and the basic supporting service functions have been continuously improved. Although the output of plastic products has slowed down, its value space is still huge and its output value can maintain a relatively high growth rate. The basic requirements of the application area to maintain steady growth, while gradually strengthening the high-end applications. Plastic processing industry is still in the rising stage of development, the transformation and upgrading are steadily advancing.
 
   Compared with foreign markets, the development of domestic modified plastics industry is relatively late. Before the 1990s, most of the modified plastics in our country needed to be imported from abroad. In recent years, the state has attached great importance to and vigorously promoted the new material industry. The market for modified plastics in our country ushered in a booming stage. The output of modified plastics increased from 5.7 million tons in 2009 to 10 million tons in 2016 The rate of sexualization also increased from 8% in 2004 to 19% in 2016. The modified plastics have been used in a wider range of applications, with a compound annual growth rate exceeding 23%.

   The development trend of "taking plastic as steel" and "taking plastic as substitute wood" provides a vast market for the development of the plastics industry. High-performance and new functional modified plastics are gradually replacing ordinary plastic and other materials to be widely used in Christmas Lighting, electronics, wire and cable, automotive and other fields. Benefit from the rapid development of many downstream industries and the rising demand for new materials, the demand for modified plastics market has been increasing at a high level in recent years.

    China is a major producer and consumer of synthetic resins. In 2015, China's total output of synthetic resins reached 76.91 million tons, an increase of 10.65% over the same period of previous year. Apparent consumption reached 103.08 million tons, an increase of 7.55% from 96.554 million tons in 20143. As a major raw material for modified plastics, overall, China's synthetic resin production capacity showed a steady upward trend, a huge consumer market. The continuous improvement of the upstream raw material supply has created the conditions for the sustainable development of the modified plastics industry.
