| 8. | The tax revenue created by the plastic machinery industry to the state was more than rmb 45 million in 1989 and up to rmb 1 . 8 hundred million in 1998 ; the quantity of the employees in plastic machinery industry is always about 100 thousand . in view of that plastic and rubber both belong to high molecular compound materials , many plastic machinery factories produce rubber machinery and plastic machinery at the same time and some of them even have its own plastic product factory . in this way , they can create more values as well as provide customers with engineering demonstrations so as to promote product distribution , improve product performances , and upgrade product grade
塑料机械行业为国家创造的税收1989年为4500多万元，到1998年已达18亿元，塑料机械行业的从业人数保持在10万人左右，由于塑料橡胶同属高分子材料，因而许多塑料机械厂同时生产橡胶机械和塑料机械，而且有的企业集团同时拥有自己的塑料制品加工厂，一方面可以更大地创造价值，另一方面可以为用户提供示范工程，促进设备销售的不断更新换代，提高产品的性能和档次。 |
