我们引入了一个基于网络的指数,分析过剩的科学生产和消费,以在大陆、国家和城市层面上对学术知识的生产和传播进行全面的全球分析。与科学生产和消费的衡量标准(如出版物数量或引用率)相比,我们基于网络的引文分析提供了一个更有差异的“科学生态系统”。通过量化2000年至2009年的知识流动,我们确定了知识生产的全球来源和汇。我们的知识流指数揭示了创意在哪里诞生和消费,从而定义了一个全球“科学食物网”。虽然亚洲在出版物和引用率方面正在迅速赶上,但我们发现其对知识消费的依赖进一步增加。
We introduce a network-based index analyzing excess scientific production and consumption to perform a comprehensive global analysis of scholarly knowledge production and diffusion on the level of continents, countries, and cities. Compared to measures of scientific production and consumption such as number of publications or citation rates, our network-based citation analysis offers a more differentiated picture of the ‘ecosystem of science’. Quantifying knowledge flows between 2000 and 2009, we identify global sources and sinks of knowledge production. Our knowledge flow index reveals, where ideas are born and consumed, thereby defining a global ‘scientific food web’. While Asia is quickly catching up in terms of publications and citation rates, we find that its dependence on knowledge consumption has further increased.
