投资要讲效益,国外有人认为:投资5年内不收回,不如存银行。回收投资有赖于规模生产,而规模生产必须依靠生产技术。为了缩短差距,要引进先进技术,引进需要外汇,不出口创汇无以支付引进所需之外汇,要使能创汇的深加工产品进入国际市场,也必须依靠生产技术。 Investment should talk about benefits. Some people in foreign countries think that if the investment is not recovered within 5 years, it is better to deposit banks. Recycling investment depends on scale production, while scale production must rely on production technology. In order to shorten the gap, it is necessary to introduce advanced technology, introduce foreign exchange that is needed, not to earn foreign exchange for foreign exchange through exports, and to enable deep processed products that earn foreign exchange to enter the international market, they must also rely on production technology.
