| 中文摘要: |
| 概述我国顺丁橡胶（BR）的发展状况。“十三五”期间，我国BR行业继续呈现产能过剩、新增装置少、产量小幅增长态势，BR供应量和需求量的年均增长率分别为6.2%和5.5%；2021年，我国BR产量约为104万t，较2020年增长1.6%，进口量约为23万t，较2020年下降24%，出口量约为9万t，较2020年增长25%；“十四五”期间，我国将有35万t·a-1新建BR装置投产，稀土BR产能增大将缓解BR同质化现象，高端产品供需平衡差距将进一步缩小。 |
| 英文摘要: |
| The development of butadiene rubber（BR） in China was summarized.During the 13th Five Year Plan period，China’s BR industry continued to show a trend of overcapacity，few new devices and small growth in output.The average annual growth rate of BR supply and demand was 6.2% and 5.5% respectively.In 2021，China’s BR output was about 1 040 000 t，an increase of 1.6% over 2020，the import volume was about 230 000 t，a decrease of 24% over 2020，and the export volume was about
90 000 t，an increase of 25% over 2020.During the 14th Five Year Plan period，350 000 t·a-1 new BR units would be put into operation in China.The increase of rare earth BR production capacity would alleviate the phenomenon of BR homogenization，and the balance gap between supply and demand of high-end products would be further narrowed. |
