据美国轮胎翻修协会报导,在1957年至1982年期间,在轮胎翻修经济方面发生了极大的变化。据统计1957年美国轮胎翻修企业约有9800个,1982年减少到3350个。1929年美国生产新轮胎的厂商有600家,而现在只有13家。这两个部门的厂商急聚减少的主要原因是,厂家合并、企业倒闭、生产管理不完善、无利润、产品质量不够高等,而有一些情况则是由于市场变化而无能力或是不愿意继续生产。 According to the American Association of Tire Renovation, during the period from 1957 to 1982, great changes occurred in the economics of tire renovation. According to the statistics, there were about 9,800 Tire Renovation companies in the United States in 1957 and 3,350 in 1982. In 1929, there were 600 manufacturers of new tires in the United States, but now there are only 13. The main reasons for the rapid decline of manufacturers in these two sectors are the merger of manufacturers, business failures, imperfect production management, no profit, and insufficient product quality. In some cases, they are unable or unwilling to continue due to market changes. produce.
