The structure and infrastructure of the Finnish research literature is determined. A representative database of technical articles was extracted from the Science Citation Index for the years 2003–2004, with each article containing at least one author with a Finnish address. Document clustering was used to identify the main technical themes (core competencies) of Finnish research. Four of the pervasive technical topics identified from the clustering (Wireless Networks and Mobile Communication, Signal Processing, Materials Science and Engineering, Chemistry) were analyzed further using bibliometrics, in order to identify the infrastructure of these research areas. Finally, the citation performance of Finnish research in the four pervasive technical topics above, and in other technical topics obtained by analysis of Abstract phrases, was compared to that of two Scandanavian countries with similar population and GDP, Norway and Denmark. 相似文献

The structure and infrastructure of the Mexican technical literature was determined. A representative database of technical articles was extracted from the Science Citation Index for the year 2002, with each article containing at least one author with a Mexican address. Many different manual and statistical clustering methods were used to identify the structure of the technical literature (especially the science and technology core competencies). One of the pervasive technical topics identified from the clustering, thin films research, was analyzed further using bibliometrics, in order to identify the infrastructure of this technology. 相似文献

The structure and infrastructure of the Indian research literature were determined. A representative database of technical articles was extracted from the Science Citation Index/Social Science Citation Index (SCI/SSCI) [SCI. Certain data included herein are derived from the Science Citation Index/Social Science Citation Index prepared by the THOMSON SCIENTIFIC®, Inc. (Thomson®), Philadelphia, Pennsylvania, USA: ©Copyright THOMSON SCIENTIFIC® 2006. All rights reserved. [1]] for 2005, with each article containing at least one author with an India address. Document clustering was used to identify the main technical themes (core competencies) of Indian research. Aggregate India bibliometrics were also performed, emphasizing the value of collaborative research to India. A unique mapping approach was used to identify networks of organizations that published together, networks of organizations with common technical interests, and especially those organizations with common technical interests that did not co-publish extensively. Finally, trend analyses were performed using other year data from the SCI/SSCI to place the 2005 results in their proper historical context. 相似文献

In this paper, Bayesian methods and the Finnish aggregate infrastructure capital series from 1860 to 2003 are used to explore how government infrastructure policy affects long-run output growth. We use Finnish data, since to the best of our knowledge the Finnish land and water construction investments series is the best available sufficiently long time series on aggregate infrastructure investments. The Finnish data provide strong and robust evidence indicating that permanent changes in government infrastructure policy have permanent effects on the growth rate of output. 相似文献

Science and technology for renewable and sustainable energy are indispensable for our future society and economics. To meet the goal of sustainable energy development, there is a growing body of research efforts world wide. The planner of energy research has to grasp the broader coverage of scientific and technological research, and make decisions on effective investment in promising and emerging technologies especially under circumstances of limited resources. In this paper, we track emerging research domains in energy research by using citation network analysis. Our analysis confirms that the fuel cell and solar cell are rapidly growing domains in energy research. We further investigate the detailed structure of these two domains by clustering publications in these domains. Each citation cluster has characteristic research topics, and there is a variety of growth trends among the clusters. By using citation network analysis, we can track emerging research domains among a pile of publications efficiently and effectively. 相似文献

This paper identifies and analyzes the science and technology core competencies of China, based on a sampling of approximately half of the total Chinese publication output in the Science Citation Index/ Social Science Citation Index (SCI/SSCI) [SCI. Certain data included herein are derived from the Science Citation Index/Social Science Citation Index prepared by the Thomson Scientific®, Inc. (Thomson®), Philadelphia, Pennsylvania, USA: © Copyright Thomson Scientific® 2006. All rights reserved. [1]] for 2005. Aggregate China publication and citation bibliometrics were obtained and a hierarchical research taxonomy, based on document clustering, was generated. Additionally, bibliometrics and thematic trends were tracked over the past two decades.The key findings were that China's output of research articles has significantly expanded in the last decade. In terms of sheer numbers of research articles, especially in cuting-edge technologies, such as nanotechnology and energetic materials, it is among the leaders. Compared to the USA, the bulk of China's articles focus on the physical and engineering sciences, while the USA articles (compared to China) focus on medical, social, and psychological sciences. 相似文献

This paper develops an empirical model to test the spatial spillover effects of transport infrastructure on economic growth.
It uses spatial econometric techniques and provincial panel data of China from 1993 to 2004 to analyze the contribution of
transport infrastructure to the economic growth of local province and its spatial spillover effects on the economic growth
of other provinces. The main findings include: (1) Transport infrastructure and economic growth of China show an evident pattern
of spatial clustering. They largely congregate in developed eastern coastal regions, forming a gradient gradually diminishing
from east to west. (2) Output elasticity of local transport infrastructure is 0.106, between the values calculated by early
researchers with time series data and panel data. (3) Spatial output spillovers from transport infrastructure are largely
positive, but evidences of negative spatial spillovers are also found with population density spatial weights matrix model.

The paper examines the impact of the Science and Technology Basic Law (STBL) enactment of 1999 on the transformation of public sector research (PSR) in Taiwan. The paper proposes a research framework to assess the changes on PSR mainly through four dimensions: (1) new infrastructure build-up, (2) industrial research links, (3) patenting and licensing, and (4) industrial education/training. Nine research hypotheses are developed. Based on the survey data of 107 PSR establishments, the paper reveals that Taiwan PSR has experienced a burgeoning infrastructure build-up and a more active partnership with industry in the post-STBL period. However, the paper argues that the scientific-economic transformation of PSR in Taiwan tends to develop better “industrial collaborative research and training capabilities” than “patenting and licensing capabilities” in the preliminary post-STBL period. The divergence on patenting, licensing and partnership capabilities still persists between experienced PSREs and non-experienced ones, suggesting a learning effect. These findings provide crucial policy implications to delineate appropriate roles of PSR in the new scientific-economic regime. 相似文献

This ‘country study’ analyses substantial samples of research papers by Brazilian authors drawn from two global databases. The approach and the findings may each be of interest. Our approach is to examine R&D outputs through bibliometrics (to identify key authors, institutions, journals, etc.) and text mining with taxonomy generation (to identify pervasive research thrusts). We extend prior country studies by providing for interactive data access and exploring military-relevant R&D information. The resulting publication activity profiles provide insight on Brazilian R&D strengths and investment strategies, and help identify opportunities for collaboration. Brazil, a nation of 190 million, evidences a substantial research enterprise, with major capabilities in the life and biomedical sciences, as well as the physical sciences. We benchmark research patterns and trends against several other countries. We find a large measure of international collaboration, particularly with the USA. 相似文献

A new bibliometric technique enables one to distinguish high emergence topical content. This technique can be applied to sets of research publication abstracts reflecting a given technical domain (here, nanotechnology) to score cutting edge research terms. The resulting high emergence terms warrant special consideration in setting R&D priorities. The researchers (individuals, organizations, or countries) whose publications address those emergent terms heavily deserve consideration as possible leaders in that technical domain. This paper studies nanotechnology research publications using the new emergence scoring in conjunction with established bibliometric publication and citation measures. Findings challenge U.S. superiority in cutting edge nanotechnology research. China shows strongest at addressing emergent nanotechnology topics, followed by the U.S., South Korea, India, and, surprisingly, Iran. 相似文献

This study estimates an aggregate production function of manufacturing industry using panel data of 11 Korean regions covering 1977–1992. While the previous studies regard infrastructure as a direct input for production, the present study proposes that infrastructure has an effect on actual output by enhancing technical efficiency thereby, reducing the gap between maximum potential output and actual output. To investigate the relationship between infrastructure and technical efficiency, a stochastic frontier approach is applied to Korean manufacturing industry. Confirming the presence of substantial technical inefficiency in production, this study shows that an increase in infrastructure reduces the technical inefficiency level. The study also finds that, contrary to expectation, the industrialized regions are less efficient than the less industrialized ones. (JEL O20, H54, C23) 相似文献
