中国科研投入的百分比并不是很高。2%，但是增速很高。科技投入比最高的是南韩。美国和日本都已经开始出现饱和趋势了。印度居然在开倒车。欧洲除了德国以外，都平平无奇。从这张图上也能看到未来带来科技突破的地域会是在哪里。 8 _' A; \" r% h: i从这张图中我们可以看到美国的创新精神已经逐渐落后于南韩了。/ W& t9 c l- N' U. P4 w4 Z. Z
Although this report does not forecast future outcomes, the data show the evolution of the United States in the global S&E enterprise. The United States continues to lead globally in R&D expenditures, S&E doctoral-level degree awards, and production of highly cited research publications. At the same time, other nations, particularly China, are rapidly developing their S&E capacity. As a result, the United States has seen its relative share of global S&T activity flatten or shrink, even as its absolute activity levels kept rising. As more countries around the world develop R&D and human capital infrastructure to sustain and compete in a knowledge-oriented economy, the United States is playing a less dominant role in many areas of S&E activity.
