美国已经不再是30年前那个以其庞大的科技论文产量雄霸科研领域的科学巨人,当今美国正与欧盟(EU27)及亚太地区各国日趋平均地分配着科研领域的“领土”。在引文影响力这一表征科研绩效、影响、重要性以及类似概念的指标方面,美国虽依然处于霸主地位,但领先优势正逐步被蚕食。欧洲已经开始在引文影响力上与美国抗衡,分析人士更倾向于预测在今后的10～20年,亚洲各国可能会有同样的表现。 The United States is no longer the scientific giant that dominated the scientific field 30 years ago with its huge output of scientific papers. Today, the United States is distributing the “territory” of scientific research on an even equal basis with the EU27 and all countries in the Asia Pacific region. The United States, while still influential in citation influence, an indicator of scientific performance, impact, importance, and similar concepts, is leading the way in its lead. Europe has begun to compete with the United States in citing its influence, and analysts are more inclined to predict that in the next 10 to 20 years, Asian countries may have the same performance.
