In this paper we compare the scientific research in the semiconductor-related field in China with some other major nations in Asia. It is based on the bibliometric information from SCI-Expanded database during the time period of 1995–2004. We show that China has been developing fast in semiconductor research, and become the second productive country in Asia as reflected by the publication profile. The evidences indicate a significant increasing trend in the research efforts and readership among Asian countries. Similar to the scientists in Japan and South Korea, Chinese scientists were more inclined to work in larger groups, typically 4 or more authors. The assessment of research quality is further conducted based on citation-based measures. As benchmarks, two western countries, namely USA and Germany, have been compared in the citation analysis. It is revealed that the impacts of research outputs in the Asian countries, except for Japan, have been badly incommensurate with their devoted research efforts compared with USA and Germany. Like most of other Asian countries the research results of Chinese scientists in semiconductor have a low international visibility despite their strong research efforts and increasingly large domestic readership. The application of Leimkuhler curve illustrates vividly the inequality of citation times among the compared countries. Furthermore, the Gini Indices of each country and each pair of countries are calculated which illustrates again the inequality of informetric productivities.  相似文献

International scientific collaboration of China with the G7 countries   总被引:2,自引:0,他引:2  
Tianwei He 《Scientometrics》2009,80(3):571-582
Collaboration is one of the remarkable characteristics of contemporary basic research. Using bibliometric method, we quantitatively analyze international collaboration publication output between China and the G7 countries based on Science Citation Index. The results indicate that international collaboration publication output between China and the G7 countries has shown exponential growth aroused by the growth of science in China. USA is the most important collaboration country and the international collaboration between China and the G7 countries display differences at each research field.  相似文献

This paper describes the different forms of and tries to give reasons for international scientific collaboration in general. It focuses on eleven countries in the Asia–Pacific region by evaluating their national research output with the help of bibliometric indicators in particular. Over two million journal articles published by these countries between 1998 and 2007 in ISI-listed periodicals are analyzed. Discipline-specific publication and citation profiles reveal national strengths and weaknesses in the different research domains. The exponential increase in publication output by China over the last few years is astonishing, but in terms of visibility, i.e. citation rates, China cannot keep up with leading science nations, remaining below the world average. A discipline-specific analysis shows that Chinese authors took an active part in more than a quarter of all articles and reviews published in the field of materials science in 2007, while their contribution to medical research is very low. Co-publication networks among the eleven countries are generated to observe the development of cooperation bonds in the region. Applying Salton’s measure of international collaboration strength, an above-average strengthening of scientific collaboration in the Asia–Pacific region can be observed.  相似文献

A bibliometric research based on the Science Citation Index Expanded was carried out to provide insights into research activities on bioinformatics in China. Annual publication output has been on continuous increase both worldwide and for China from 1998 to 2012. In recent years, China showed faster growth rates than world average. As the second productive country in the field of bioinformatics, China did not do equally well in terms of citation counts and h-index. Chinese Academy of Sciences and Shanghai Jiao Tong University were among the ten most productive institutes in the world, and their basic metrics and collaboration patterns were compared with other institutes, especially two institutes from Japan. The journal PLoS One was found to have published the most papers from China. In addition, this paper compared the most active categories in Web of Science worldwide with those of China. Personal perspectives of bioinformatics research in China were also presented.  相似文献

Based on data from the Web of Science, international collaboration between China and the UK in food and agriculture has been investigated from various perspectives. A new method for classifying cross- or multi-disciplinary fields has been created. The comparative study focuses on China’s collaboration with selected countries including the USA, the UK, Germany and Japan. The newly proposed Integrated Impact Indicator (I3) is applied to evaluate publication impact. Although China’s total publications dropped in 2010, its research productivity in food and agriculture nevertheless kept growing and international collaboration, reflected by the number of publications, also increased in an exponential way. The growth rate of China’s internationally collaborated publications was lower than that of China’s total publications. The USA, Japan, Canada, Australia, the UK and Germany are the top partners for Chinese researchers in this field. China-UK joint publications overall increased although their share in China’s total internationally collaborated publications decreased. To China, collaborating with the USA, the UK and Germany, instead of Japan, seems to offer an option to raise impact. The rapidly growing number of international publications and impact of Chinese research in food and agriculture offers great collaboration potential for the country. The fact that the average impact of China-UK collaborative publications is higher than the domestic publications of either country implies that collaboration benefits both sides as has been found in several other studies.  相似文献

Along with China’s economic emergence is a controversy over the quality and international visibility of citation index publications. This study uses bibliometric statistics to shed further light on the global landscape of citation index publications with special focus on China and the USA. The analysis explores 31 years of the TRS (Thomson Reuters Scientific) database, spanning the 1980–2010 period. Based on this study, the USA maintains global dominance for both WOK (Web of Knowledge) and WOS (Web of Science) TRS publications. Although China ranks a distant second for WOK, it lags behind five other nations for WOS publications. China’s scientific base needs further restructuring for greater global visibility. Emerging economies such as China, India, Brazil and South Africa are fast rising in the global ranks for WOK/WOS publications. China may already be leading the world in some publication attributes, although it could take several more decades to catch up with the USA in others. Normalizations of the publications with population, PTE (population with tertiary education) and GDP (gross domestic product) put small/low-population countries in the global lead. However, countries such as Canada, Greenland, Iceland and Sweden still rank high for most of these publication attributes. Furthermore, WOS per WOK analysis shows that small and/or economically weak countries place greater emphasis on WOS publications. This is particularly visible for countries in Africa and South America. Despite the addition of a large number of indigenous Chinese journals to the TRS database, prediction analysis suggests that China’s desire to surpass the USA could be delayed for several decades. In the race for the next-generation scientific superpower, however, China not only needs to sustain substantial investments in research and development, but also requires restructuring of its research industry. This is especially critical for data readiness, availability and accessibility to the scientific community, and radical implementations of research recommendations.  相似文献

The long-term influence and contribution of research can be evaluated relatively reliably by bibliometric citation analysis. Previously, productivity of nations has been estimated by using either the number of published articles or journal impact factors and/or citation data. These studies show certain trends, but detailed analysis is not possible due to the assumption that all articles in a journal were equally cited. Here we describe the first comprehensive, longterm, nationwide analysis of scientific performance. We studied the lifetime research output of 748 Finnish principal investigators in biomedicine during the years 1966–2000, analysed national trends, and made a comparison with international research production. Our results indicate that analyses of the scientific contribution of persons, disciplines, or nations should be based on actual publication and citation counts rather than on derived information like impact factors. 51% of the principal investigators have published altogether 75% of the articles; however, the whole scientific community has contributed to the growth of biomedical research in Finland since the Second World War.  相似文献

Using bibliometric methods, we investigate China’s international scientific collaboration from three levels of collaborating countries, institutions and individuals. We design a database in SQL Server, and make analysis of Chinese SCI papers based on the corresponding author field. We find that China’s international scientific collaboration is focused on a handful of countries. Nearly 95 % international co-authored papers are collaborated with only 20 countries, among which the USA account for more than 40 % of all. Results also show that Chinese lineage in the international co-authorship is obvious, which means Chinese immigrant scientists are playing an important role in China’s international scientific collaboration, especially in English-speaking countries.  相似文献

We performed a bibliometric analysis of published research on Global Positioning System (GPS) for the period of 1991–2010, based on the Science Citation Index and Social Sciences Citation Index databases. Our search identified a total of 15,759 GPS-related publications in the period. We analyzed the patterns of publication outputs, subject categories and major journals, international productivity and collaboration, geographic distribution of authors, and author keywords. The annual number of publications in GPS research increased from 98 in 1991 to 1934 in 2010. “Geochemistry & Geophysics”, “Geosciences, Multidisciplinary”, and “Engineering, Electrical & Electronic” were the top 3 most popular subject categories. As the flagship journal in the field, Geophysical Research Letters had the highest publication count. The USA, the UK and Germany were the top 3 most productive countries. The most productive institution was the California Institute of Technology (Caltech), followed by the Chinese Academy of Sciences and the University of Colorado. The USA was the most frequent partner in international collaborations. Caltech took the central position in the collaboration network. The major spatial clusters of authors were in the USA, the Europe Union, and East Asia (including China, Japan and South Korea). “Ionosphere”, “Remote Sensing” and “Monitoring” are growing research subjects in the field of GPS, while “Deformation”, “Geoid” and “Tectonics” are becoming gradually less significant. Our study revealed underlying patterns in scientific outputs and academic collaborations and may serve as an alternative and innovative way of revealing global research trends in GPS.  相似文献

This review study is a first attempt to map the state of entrepreneurship research in China by focusing on the contributions of Chinese researchers. Leading contributors, research collaboration and theoretical underpinnings in both domestic-oriented and international-oriented research are discussed. The review comprises 508 articles published in domestic Chinese journals indexed by the Chinese Social Science Citation Index and 189 articles published in international journals indexed by the Social Science Citation Index between 2000 and 2011. Two bibliometric approaches, co-authorship analysis and co-citation analysis, were utilized. The results indicate that entrepreneurship research in China is characterized by a clear division, not only in terms of researchers in each community, collaborating network but also with regard to theoretical foundation. Domestic-oriented research is still in its infancy. The research community has attracted a majority of Chinese researchers who focus on inter-institutional collaboration based on mentorship and directing relationship. Scholars involved in international-oriented research engage in more open communication by collaborating not only with researchers from other Chinese institutions but also with those from foreign countries. At the same time, they contribute to the understanding of Chinese entrepreneurship by linking the entrepreneurship phenomenon in Chinese context to theoretical frameworks.  相似文献

We introduce a new quantitative measure of international scholarly impact of countries by using bibliometric techniques based on publication and citation data. We present a case study to illustrate the use of our proposed measure in the subject area Energy during 1996–2009. We also present geographical maps to visualize knowledge flows among countries. Finally, using correlation analysis between publication output and international scholarly impact, we study the explanatory power of the applied measure.  相似文献

Nanobiopharmaceuticals is a hopeful research domain from recent scientific advances with massive marketable potential. Although some researchers have studied international collaboration from some aspects, few articles are as comprehensive as this article to consider international cooperation from so many different aspects. We lay more emphasis on international collaboration in the field of nanobiopharmaceuticals involving China. Incremental citation impact values show that in order to move forward and improve the overall competitiveness in the field, China requires to carry out more international collaboration in the field, especially with USA, Germany, and England. Startlingly, multinational collaboration does not sway Chinese citation impact as much as we anticipate in the field. China has reached the first rank in the world in terms of publication amount per year in the field in 2009. Few papers about international collaboration compare small world phenomenon. We use small world quotient to find that it is important for Chinese international co-authors to strengthen to cultivate a cooperation networks in which a node’s partners are also buddies to each other.  相似文献

This study applies bibliometric analysis to investigate the quantity and citation impact of scientific papers in the field of complementary and alternative medicine (CAM). The data are collected from 19 CAM journals in the Science Citation Index Expanded (SCI-E) database during 1980–2009, and 17,002 papers are identified for analysis. The study analyzes the document types, geographical and institutional distribution of the authorship, including international scientific collaboration. This study suggests that the major type of document is original article. The CAM papers are mostly published by North America, East Asia, and European countries, of which publications authored in East Asia are cited most. Country-wise, major contributors of CAM papers are from USA, People’s Republic of China, India, England and Germany. India has the highest CPP value, attracting high attentions in CAM community. This article also finds that international co-authorship in the CAM field has increased rapidly during this period. In addition, internationally collaborated publications generate higher citation impact than papers published by authors from single country. Finally, the research identifies productive institutions in CAM, and China Medical University located in Taiwan is the most productive organization.  相似文献

SCI data bases have been widely used to analyse scientific production of various nations, their position in the international research community as well as their fields specializations. In the present study we examined, within the same methodological framework, the impact of the drastic reorientation of science funding systems which occured in China (PRC) in the midst of the eighties. A decade after this turning point the pattern of Chinese publications from the 1994 SCI-CDRom reflects those of other countries although with its own peculiarities i.e. a relative weakness of life sciences and a prevalence of fundamental physics compared to the world average. Some effect of PRC's policy could nevertheless be detected on this SCI profile like e.g. a neat increase of international papers after the opening of the country or the relatively high weight of collaborative works with laboratories from Hong Kong. We suggest that SCI data base is best suited for the analysis of public research of international standard due to the narrowness of the SCI window concerning applied research.  相似文献

It is widely accepted that biotechnology is a globally significant and growing research field. Because of its biodiversity, Colombia has a comparative advantage to innovate and commercialize biotechnological products and services. The aim of this study is to obtain a research profile and intellectual structure of the country in the biotechnology field by using bibliometric methods. These methods are needed to monitor the capacities and the compliance of national policies in biotechnology. By using records extracted from the ISI WoK database, this study describes the biotechnology publication trend, productivity and collaboration among institutions and countries, preferred journals, and the intellectual structure at the research subject area. Although, a growing trend in biotechnology publication was observed, the productivity is still low when compared to other countries in the region and the world. On the other hand, researchers seem to show a preference for international over domestic collaboration. The results suggest two elements: first, policy has not had the expected outcome in the short term, and second, a lack of internal collaboration could therefore reflect low endogenous capacities. The bibliometric methods used in this study can be applied to a wide range of research fields other than biotechnology.  相似文献

This paper describes a new and objective method for tackling the problem of defining a multidisciplinary research area for bibliometric analysis. The test field was cardiovascular biology. A three stage process was adopted in setting a boundary around this research field:
  1. Appropriate sections of a hierarchical subject classification scheme, Medical Subject Headings (MeSH), were developed into a “MeSH filter” through which papers indexed in MEDLINE were screened.
  2. A panel of cardiovascular experts reviewed the core set of classification terms, identifying irrelevant and missing areas, facilitating the development of a more sophisticated “filter”.
  3. The definition was validated using publication lists from research departments with a known interest in cardiovascular research.
This iterative process resulted in a definition of the field which captured basic and clinical research papers from the international biomedical research community and which was recognisable to experts in the field of cardiovascular research. Importantly, the field boundary also excluded publications which were not relevant to cardiovascular research. The process of involving experts in shaping the field definition also yielded two intangible, but key benefits: (a) it lent credibility to subsequent analyses, the results of which were to be presented to policy-makers in cardiovascular biology, and (b) it served to shape consensus among the cardiovascular experts on the full range of scientific disciplines that are relevant to their field. Analysis of international publishing in cardiovascular research revealed that whilst the UK and US dominate in total numbers of papers, the relative emphasis on cardiovascular research in these countries (as a proportion ofall biomedical publishing) is actually quite low, and declining. Japan and Germany in contrast appear to give greater emphasis to cardiovascular research in their national portfolios of biomedical science, and between 1988–1991 Japan established a marked increase in activity.  相似文献

This paper presents a selection of results of a comprehensive quantitative, research literature-based study of Dutch energy research. The primary goal of this paper is to provide an overview of what bibliometric data from ISI and non-ISI databases may offer to describe the state of affairs in a scientific field. It illustrates the added value of combining bibliometric indicators of publication output, international visibility, international co-operation, and interdisciplinarity in a study of nuclear energy research in the 1980's when its budget decreased dramatically.  相似文献

Measuring China"s research performance using the Science Citation Index   总被引:8,自引:0,他引:8  
Moed  Henk F. 《Scientometrics》2002,53(3):281-296
This contribution focuses on the application of bibliometric techniques to research activities in China, based on data extracted from the Science Citation Index (SCI) and related Citation Indexes, produced by the Institute for Scientific Information (ISI). The main conclusion is that bibliometric analyses based on the ISI databases in principle provide useful and valid indicators of the international position of Chinese research activities, provided that these analyses deal properly with the relatively large number of national Chinese journals covered by the ISI indexes. It is argued that it is important to distinguish between a national and an international point of view. In order to assess the Chinese research activities from a national perspective, it is appropriate to use the scientific literature databases with a good coverage of Chinese periodicals, such as the Chinese Science Citation Database (CSCD), produced at the Chinese Academy of Sciences. Assessment of the position of Chinese research from an international perspective should be based on the ISI databases, but it is suggested to exclude national Chinese journals from this analysis. In addition it is proposed to compute an indicator of international publication activity, defined as the percentage of articles in journals processed for the ISI indexes, with the national Chinese journals being removed, relative to the total number of articles published either in national Chinese or in other journals, regardless of whether these journals are processed for the ISI indexes or not. This indicator can only be calculated by properly combining CSCD and ISI indexes. This revised version was published online in June 2006 with corrections to the Cover Date.  相似文献

This study investigates the scientific output and publication patterns of Korean biotechnology before and after the start of the Korean Biotechnology Stimulation Plans (1994–2007), and then compares the results with publication data from the same time periods for Japan, the People’s Republic of China, Taiwan and Singapore. For this study, 14,704 publications, published by at least one researcher from one of the five Asian nations (indexed by SCI Expanded during the years 1990–1993 and the years 2000–2003), were considered. A marked increase of Korean research output in biotechnology was largely influenced by an increasing tendency for researchers to enter the field of biotechnology and by increased expenditures for R&D activity through the Korean Biotechnology Stimulation Plans. In addition, the SCI Expanded coverage of national journals affected the scientific output and publication patterns of Japanese and Korean researchers. Looking at the Korean publications by collaboration type, international collaboration leads to more publications in mainstream journals of high impact factors than local and domestic collaborations for the two periods. However, although the Korean Biotechnology Stimulation Plans were followed by a remarkable increase in South Korea’s research output, this increase has not been accompanied by growth in the quality of those publications in terms of impact factors of journals for Korean publications.  相似文献
