传统的产业理论并未对产业变迁的规律给予一个满意的解释。20世纪90年代以后才发展起来的演化经济学将产业问题的研究建立在微观企业行为的基础上。演化经济学认为,企业产品设计和生产管理的创新,通过市场的自然选择过程,能够满足经济需要的“更好的”产业部门随着时间推移而不断发展,比重增加,经济结构因此发生了变化。
Traditional economics does not explain the industrial transformation satisfactorily. Evolutionary economics, which was developed after 1990's, is based on the micro behaviors of enterprises. It explores the idea that innovation is central to a process of economic development and that it underpins the selftransformation of economic systems and structural change.
