The consumption of PVC resin in China is mainly concentrated in South China and East China. The consumption of Guangdong, Zhejiang, Fujian, Shandong and Jiangsu provinces accounts for about 70.0% of the total consumption in China. Among them, Guangdong and Fujian provinces have large market demand, but the production capacity is insufficient, and the proportion of imported PVC resin is high;; The PVC resin processing industry in Jiangsu, Shandong and Zhejiang provinces is relatively developed, and the consumption of the three provinces accounts for about 34.0% of the total domestic consumption; Production and marketing in North China are basically balanced. With the strengthening of development in the central and western regions and the construction of large-scale infrastructure, the consumption of PVC resin in the central and western regions will gradually increase.
