进入21世纪以来,在聚氯乙烯、1,4-丁二醇等下游产业需求激增的带动下,电石行业进入产能快速增长期。截至2012年底,国内电石产能达到3230万吨/年,产量提高到2000万吨以上,但开工率仅为62%。尽管产能过剩矛盾已经凸显,但企业对于电石行业的投资热情依然高涨。预计到2015年国内电石产能将达到5400万吨/年,即使内燃炉全部淘汰,产能仍将有4000万吨/年;到2020年,即使国家不再审批新项目,国内电石产能也会超过5500万吨/年。多年来,我国电石行业粗放式发展,积累了不少深层次矛盾,充分认识、深入分析行业发展的主要问题和矛盾,对于加快转变经济发展方式,全面提升行业发展质量具有十分重要的现实意义。
Since the beginning of the 21st century, driven by the surge of demand from downstream industries such as PVC and 1,4-butanediol, the calcium carbide industry has entered a period of rapid growth of production capacity. As of the end of 2012, the domestic calcium carbide production capacity reached 32.3 million tons / year, the output increased to more than 20 million tons, but the operating rate was only 62%. Despite the overcapacity contradictions have been highlighted, but the business investment in calcium carbide industry enthusiasm is still rising. It is estimated that domestic calcium carbide production capacity will reach 54 million tons / year by 2015, and even if the internal combustion furnace is completely eliminated, the production capacity will still be 40 million tons / year; even if the state no longer approves new projects, the domestic calcium carbide production capacity will exceed 5,500 tons Tons / year. Over the years, the extensive development of China’s calcium carbide industry has accumulated a lot of deep-seated contradictions, fully understand and in-depth analysis of the main problems and contradictions in the development of the industry. It has very important practical significance for accelerating the transformation of the mode of economic development and comprehensively enhancing the quality of the development of the industry.
