这张图显示出来美国人民对于科学还是有很多,正面的评价。学位越高,对于科学的信心也越强 % h4 \6 `1 e; C比较这一份报告和2014年的报告,才发现有很多东西改变了。2014年的报告还很细致详尽的讨论了幼儿园有四年级到八年级,以及国际上的数学和科学的教育成果。而这份2020年的报告,基本上更加关注的都是国际的竞争形式。 2 l3 r/ F0 @, [$ p5 l 0 q, q; [) i5 T/ l8 [4 U( s
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.
