ITIF：2026年评估美国汽车工业全球竞争力的演变报告（英文版）

Reaching its zenith in the 1950s, the U.S. auto industry has been in a period of decline since at least the mid-1960s when it began to face import competition from leaner Japanese and European competitors.While the Big Three automakers—General Motors, Ford, and Chrysler—accounted for 92 percent of domestic auto share in 1965, this share would fall by half, to 46 percent, by 2015, and to 38 percent by 2024.
