根据中央工业与地方工业并举,大中小并举的工业发展方针,产品逐级下放。过去只能做简单农具的工厂,现在要生产拖拉机;过去只能做纺织机械的工厂,现在要生产整套的轧钢设备;过去只有一般中型设备的工厂,现在要朝着生产高级、精密、大型产品发展。这样才能使机械工业全面满足工农业高速度发展的需要。但是产品下放后,不少工厂原有的设备体型小、精度差、效率低,同时缺少许多专用设备,返样产品和设备就形成了一个突出的矛盾。在 According to the principle of industrial development of both central and local industries, large, medium, and small, the products are progressively decentralized. Plants that used to be simple farm implements in the past are now producing tractors; factories that used to be only textile machinery in the past are now producing complete sets of steel rolling equipment; factories that used to be only medium-sized equipment in the past are now moving towards the production of advanced, sophisticated, large-scale products. development of. Only in this way can the machinery industry fully meet the needs of high-speed development of industry and agriculture. However, after product decentralization, many of the factory’s existing equipment is small in size, poor in accuracy, and low in efficiency. At the same time, it lacks many special equipment. The return of products and equipment has formed a prominent contradiction. in
