随着中国经济的迅速发展，国内对聚酯切片的表观消费量迅速增长。中国的聚酯产能迅速发展。2004年世界石油价格的波动引发国际原料市场行情的变化，而中国聚酯原料产业的发展严重滞后于下游产业，国内聚酯原料市场进口的依存度很高，受此影响2004年聚酯系列行情完全被聚酯原料的走势主导，在成本推动下呈现持续攀涨态势。
With the rapid development of China's economy, the apparent consumption of polyester chips in China is growing rapidly. China's polyester production capacity is developing rapidly. In 2004, the fluctuation of the world oil price caused the change of the international raw material market, while the development of China's polyester raw material industry lagged behind the downstream industry seriously, and the domestic polyester raw material market was highly dependent on imports. Affected by this, the polyester series market in 2004 was completely dominated by the trend of polyester raw materials, and showed a continuous upward trend driven by the cost.
在全年上涨的同时，石化行业下游价格传导趋弱的特征使聚酯行业的效益大幅下滑，涤纶纤维更是临近亏损边缘，聚酯产业进入行业洗牌的低迷期。在此市场状况下 ，生产企业尤其需要产业的宏观、微观分析，需要对国际国内的生产、销售、市场竞争、市场格局、国际贸易等方面进行研究调查，以制定相应的战略和发展计划。
At the same time of the year's rise, the weakness of price transmission in the downstream of petrochemical industry makes the benefits of polyester industry drop sharply, polyester fiber is close to the edge of loss, and polyester industry has entered the downturn period of industry shuffling. In this market situation, the production enterprises especially need the macro and micro analysis of the industry, and need to research and investigate the production, sales, market competition, market pattern, international trade and other aspects at home and abroad, so as to formulate corresponding strategies and development plans.
