摘　　要：我国聚氯乙烯(PVC)生产结构以电石法工艺为主,而工艺更环保的乙烯法由于成本较高等因素应用发展缓慢。通过搭建PVC生产成本与原料价格的简单模型,预测在未来一段时间内,国内电石法PVC产能虽将占据主导地位,但乙烯法PVC的成本优势会逐渐显现,乙烯法PVC替代电石法PVC会成为趋势。It is found that the capacity growth of PVC by ethylene process is slower because of high cost,although it is more environmentally friendly.By modeling the production costs of PVC by calcium carbide process and PVC by ethylene process,this paper predicts that PVC produced by calcium carbide process will still dominate the domestic market,but PVC produced by ethylene process will replace it gradually with cost reduction for a long time.
