中国塑料产品产量的增长与国民经济GDP的增长有较好的相关性,1983～1998年塑料产品产量的年均增长率是同期GDP的1.6倍(1983～1998年GDP年均增长率为10.3%,而合成树脂消费量年均增长率为16.7%)。2000～2005年中国GDP的增长率按7%计算,2006～2015年GDP年增长率按6%计算,中国塑料产品产量的年增长率预计为10%,2006～2015年年增长率预计为8%,相应的产量分别为2500万t和5000万t。长期以来,中国塑料工业使用的合成树脂材料大量依赖进口。1983～
The growth of China’s plastic product output has a good correlation with the growth of the national economy. The average annual growth rate of plastic product output from 1983 to 1998 was 1.6 times the GDP of the same period (the average annual growth rate of GDP from 1983 to 1998 was 10.3%. , while the average annual growth rate of synthetic resin consumption is 16.7%). The growth rate of China’s GDP from 2000 to 2005 is calculated at 7%. The annual growth rate of GDP from 2006 to 2015 is calculated at 6%. The annual growth rate of China’s plastics production is expected to be 10%, and the annual growth rate from 2006 to 2015 is expected to be 8 %, the corresponding output was 25 million tons and 50 million tons respectively. For a long time, the synthetic resin materials used in China’s plastics industry have relied heavily on imports. 1983～
