经济部门
经济行业类型
（重定向自经济成分）
- 第一产业：涉及原料和生产，例如玉米、煤炭、木材和铁矿开采。（煤矿工人、农民或渔民是第一产业工人。）
- 第二產業：涉及将原材料或中间材料转变为商品，例如将钢铁制造成汽车，或将纺织品制造成服装。（建筑工人和裁缝属于第二产业工人。）
- 第三产业：涉及向消费者和企业提供服务，例如育婴、电影业和银行业。（店主和会计师是第三产业的工人。）
到了20世纪，经济学家开始认为，传统的三级服务可以进一步区分出“第四产业”和“第五產業”的服务业部门。第四产业部门的经济活动包括基于信息和知识的服务，而第三产业服务包括人类服务和招待性行业相关的产业。[2]

Regarding the terminology itself Clark informs that "the term tertiary industries was originated by Professor A. G. B. Fisher in New Zealand, and became widely known through the publication of his book, The Clash of Progress and Security, in 1935. It took its origin from the titles current in Australia and New Zealand of 'primary industry' for agriculture, grazing, trapping, forestry, fishing and mining, and 'secondary industry' for manufacture. In Australia and New Zealand these terms are not only used in statistical reference books but are widely current in popular discussion. The phrase 'tertiary industries' therefore immediately carries, in these countries, a suggestion of those excluded by the official definition of 'secondary industries."
