通过简述粘胶基炭纤维生产技术的发展概况和国内外市场情况，可看出国内外差距越来越大。粘胶基炭纤维具有其它纤维不可替代的优异性能，国内市场严重的供不应求。从技术经济角度分析其发展的制约因素，原丝质量制约其产品性能，投资比较大、成本较高，生产研究的投入不足制约其发展。同时简单分析了其社会效益，对我国粘胶基炭纤维发展提出了几点建议。
The present state of R & D as well as market-consumption of Rayon-based CF in China and other nations was described. It seems that the gap between China and other nations shows a tendency to be more and more wider. The supply of Rayon-based CF can not meet the demand of our country. From the standpoint of techno-economics, the factors limiting the development of Rayon-based CF were analyzed and summarized. The quality of raw Rayon-based fibers is so critical that it has a great influence in the properties of Rayon-based carbon fibers. Other factors like high investment, high cost and small amount of invested funds for research and production are also important. Social benefit of Rayon-based carbon fibers was simply analyzed. Some suggestions for the development of Rayon-based carbon fibers in China were put forward.
