Industrial policies – in which governments intervene in the allocation of resources among sectors or favor some technologies over others – can help “infant economies” learn. Learning may be more marked in some sectors (such as industrial manufacturing) than in others, and the benefits of that learning, including the institutional development required for success, may spill over to other economic activities.
产业政策——政府干预资源在各部门间的配置或优待某些技术——有助于“婴儿经济体”（infant economy）学习。一些部门（如工业生产部门）的学习可能会胜过其他部门，而学习的好处，包括成功所必须的制度发展——可能溢出到其他经济活动中。
