220 美国服务业
段1
Productivity: 现实问题1945-1965 annual 3% , 1970s 1% -> Why? Not manufacturing sector (have big improvement, constitute a small proportion) -> Service sector's productivity growth declined -> several explanations: traditional measures' failure, these focus on improved quality -> strong foreign competition in manufacturing, However! this is overstated, often for political reasons and some simply because slow growth in demand
Why 1970s 生产力增长降低,从数据看是因为服务业,两解释,一是传统测算方式,随后反驳解释1,二是制造业受国外竞争影响工作效率更高,随后反驳解释2
段2
解释3,如果财政赤字低,利率低,新兴技术投资增加,刺激服务业生产率提高。但服务业没能利用起来。有的公司利用好了生产率提高了。
服务业停滞不前的罪魁——外力比如收购和政府管制->让管理者没能有效利用资源 |
