评价国家科学生产的二维方法(案例研究:基础科学)

A Two-Dimensional Approach to Evaluate the Scientific Production of Countries (Case Study: The Basic Sciences)

Ammar Nejati, Seyyed Mehdi Hosseini Jenab

摘要:

研究了近12年(1996-2007年)来世界前50名国家在农业和生物科学、化学、数学、物理和天文学四个基础科学领域的科学产出的数量和质量。为了对国家进行排名,本文借鉴了H指数和其他基于质量和数量指标的方法,提出了一种新的二维方法。各国的数据以“数量-质量图”表示,并通过传统的统计算法(k-均值)划分为三个集群,其成员在所有基础科学领域都相当相同。研究结果为各国在科学产出方面的全球地位提供了一个新的视角。

英文摘要:

The quantity and quality of scientific output of the topmost 50 countries in the four basic sciences (agricultural and biological sciences, chemistry, mathematics, and physics and astronomy) are studied in the period of the recent 12 years (1996-2007). In order to rank the countries, a novel two-dimensional method is proposed, which is inspired by the H-index and other methods based on quality and quantity measures. The countries data are represented in a "quantity-quality diagram", and partitioned by a conventional statistical algorithm (k-means), into three clusters, members of which are rather the same in all of the basic sciences. The results offer a new perspective on the global positions of countries with regards to their scientific output.
