摘 要:分析了中国聚酯产量估算的现状,其存在的主要问题是概念不明确、估算不及时、数据不准确等;介绍了准确估算中国聚酯产量的方法和步骤:以涤纶产量为聚酯产量估算的主要变量,及时进行月度产量估算,并进行数据修正、复检与验算;建议中国聚酯产量的估算工作应进一步明确概念,细分品种统计,提高估算人员的估算水平。The current situation of China polyester output estimation was analyzed. The existing principal problem was indefinite concepts, untimely estimation and inaccurate data. The method and procedures of China polyester output estimation were introduced as followed: using polyester fiber output as the key variable of polyester output estimation and conducting monthly output estimation and data correction, checking and rechecking in time. It was suggested that China polyester output estimation should further define the concept, subdivide variety statistics and improve the estimate level of estimators.
