【答案解析】成功的知识经济要求政府在教育、基础设施及研究与开发领域里投入巨资。
有些国家愿意在研究开发方面投资，也有些国家不愿意这么做。对国家或公司来说，技术上的领先地位与研究开发的投入是两码事。
欧洲在研究方面也有相当的投入，但反观其在技术上的排位，这种花费似乎没有产生应有的效果。
显而易见，要使投入产生效益，就必须继研究之后开展必要的、使新开发的技术应用于经济的活动。 [解析]
A successful knowledge-based economy requires large public investments in education, infrastructure, and research and development.
Some countries are willing to invest in research and development; others are not. For countries or companies technological leadership is not the same thing as R&D spending.
Europe spends its share on research, but if one looks at technological leadership, that spending does not seem to be paying off.
To pay off, obviously, research has to be followed by the activities necessary to embed the newly developed technologies in the economy.
