China's statistical system and resources     

Susan Xue 《Journal of Government Information》2004,30(1):87-109

As the People's Republic of China plays an increasingly important role in international politics and trade, countries with economic interests there find they need to know more about this nation. Access to primary information sources, including official statistics from China, however, is very limited, as little exploration has been done into this closely controlled repository of information. This study explores major current statistical sources in China through examining (a) the statistical system in Chinese government, (b) the mechanism of statistical data collection, and (c) what statistical information is currently available in both print and electronic format and at what level. It shows that a wealth of statistical information does exist in China, it is systematically compiled, and it is available, although not conveniently, to the public through various channels. This study can serve the need for China's data from the academic and business communities, contribute to a better understanding of China's statistical system, and serve as a collection tool for academic, public, and corporation libraries as well.  相似文献

Technological research in the EU is less efficient than the world average. EU research policy risks Europeans’ future     

Alonso Rodríguez-Navarro  Ricardo Brito 《Journal of Informetrics》2018,12(3):718-731

We have studied the efficiency of research in the EU by a percentile-based citation approach that analyzes the distribution of country papers among the world papers. Going up in the citation scale, the frequency of papers from efficient countries increases while the frequency from inefficient countries decreases. In the percentile-based approach, this trend, which is uniform at any citation level, is measured by the e_p index that equals the P_{top 1%}/P_{top 10%} ratio. By using the e_p index we demonstrate that EU research on fast-evolving technological topics is less efficient than the world average and that the EU is far from being able to compete with the most advanced countries. The e_p index also shows that the USA is well ahead of the EU in both fast- and slow-evolving technologies, which suggests that the advantage of the USA over the EU in innovation is due to low research efficiency in the EU. In accord with some previous studies, our results show that the European Commission’s ongoing claims about the excellence of EU research are based on a wrong diagnosis. The EU must focus its research policy on the improvement of its inefficient research. Otherwise, the future of Europeans is at risk.  相似文献
