今年年初,美国国家科学基金会发布的《美国科学与工程指标》(以下简称“《指标》”)显示,中国科技在全球的地位日益突出,已成为不容置疑的世界第二研发大国。研发投入、科技论文产出、高技术制造增加值等均居世界第二位,理工科人才供应世界笫一,风电能力世界第一。《指标》显示,全球研发支出总体呈上升趋势,集中在北美、欧洲及东亚和东南亚地区。美国仍然是世界第一研发大国,中国居第二位,中国的研发开支接近欧盟的总和。在按购买力平价计算的全球研发总支出当中,中国约占20%,仅次于
Earlier this year, the “U.S. Science and Engineering Indicators” released by the National Science Foundation showed that China’s science and technology have become increasingly prominent in the world and have become the second largest research and development power in the world. R & D investment, output of scientific papers, the added value of high-tech manufacturing ranks second in the world, science and technology personnel supply the world Zi, wind power capacity in the world. “Indicators” show that the overall R & D spending worldwide upward trend, concentrated in North America, Europe and East Asia and Southeast Asia. The United States remains the largest research and development power in the world with China ranking second. R & D spending in China is close to the sum of the EU. Among global R & D expenditures calculated at purchasing power parity, China accounts for about 20%, second only to
