Introduction

Polypropylene (PP) resin is a semi-crystalline thermoplastic polymer resin derived from propylene. PP resin is an important material with many physical and chemical properties, and is widely used in the manufacture of all kinds of film, hollow container, pipe, electrical appliance, furniture and daily necessities. In recent years, with the increasing production and consumption of polypropylene in China, PP has become an important indicator of the development of modern chemical industry.

PP resin production in China is mainly concentrated in the East China, South-west, Central China, North China and other regions. According to the National Statistical Bureau on the Statistics of PP resin industry from 2012 to 2017, the annual output of PP resin in China reached more than 66.8 million tons in 2017. This includes large and small enterprises.

Analysis of Regional Production Patterns

East China

East China is the largest production area of PP resin in China. It currently has the largest PP resin production capacity in China. The PP resin production in this area mainly depends on the Yangtze River Delta and Pearl River Delta. Among them, with Zhejiang, Jiangsu, Shanghai and Fujian as the mainstream, 80% of China’s total output is concentrated in ports. The PP resin produced in this area has the advantages of low price, and is usually controlled by foreign firms, which enhance the competitiveness of PP resin based on the integration of upstream and downstream industrial structure.

South-west

South-west China is the second largest production region of PP resin in China. Due to the vast area of the Southwest, the technological level of polypropylene production enterprises is not high, and most of them are small and medium-sized production enterprises. However, the region has always been the leader in terms of PP resin technology, which is the mainstay of China's PP resin industry. Due to the relatively high production cost, PP resin produced in the Western China has become a main force to meet the increasing domestic demand.

Central China

The Central China is the third largest production region in China. PP resin production in this area is mainly concentrated in Hubei, Henan, and Hunan, with emphasis on Hubei. Central China's PP resin product market positioning is mainly in the lower-end consumer market, with low price and low value added.

North China

North China is the fourth largest production base of PP resin in China. In terms of production capacity, the main production regions of PP resin in North China are concentrated in Shandong, Tianjin and Beijing. In this area, the total output of PP resin is relatively small, with a certain gap compared with East China, South-west and Central China, and the main production mode is medium-sized plants.

Conclusion

Through analysis of the production pattern of PP resin in China, we see that the concentration of output is mainly concentrated in the East China, South-west, Central China and North China regions. East China is the main production area of PP resin, accounting for nearly 80% of the national output. In recent years, the production capacity of polypropylene in various regions of China has not only increased, but also the quality of polypropylene products has improved. Moreover, the price of PP resin in different regions has been differentiated, indicating that the regional pattern of PP resin is in constant change. Therefore, in the future, the regional product differentiation of polypropylene will cast a heavy weight on the development of China's PP resin industry and production.
