Bibliometrics Analysis of the Scientific Publication of the Provincial Capital Cities CDC in China

摘要

Aims: To objectively evaluate the level of scientific research of Centers for Disease Control and Prevention (CDCs) of the provincial capital cities in China. Design??? To compare each capital city’s scientific research output in China, the authors used authoritative Chinese databases to retrieve scientific research literature published by the 31 Chinese provincial capital cities CDCs nationwide published between January 2007 and December 2011. Data were stored and analysed using NoteExpress2.0 software. Place and Duration of Study: Department of Medicineand the Centers for Disease Control and Prevention, between May 2012 and July 2012. Methodology: All the articles published by the CDCs of provincial capital cities between 2007 and 2011 were retrieved from scientific literature databases. Data were stored and analysed in NoteExpress2.0 reference management analysis software. Bibliometric methods were used to statistically analyze the data. We developed an Overall influence index (∑IFN) which combined the number of published papers and the impact factor for each one (IF) to derive an overall and objective index. Results: Overall 9,445 Chinese language and 202 English language papers fulfilled our inclusion criteria. A gradual upward trend in published literature of provincial capital cities CDC was observed between 2007 and 2011. The co-author rate was relatively high and the content of the journals was extensive. The Overall influence index of Beijing CDC is the highest (626.682),and Lasa CDC gets the lowest(1.354). Conclusion: The development of the level of scientific research is uneven in different areas. The ∑IFN index of the developed regions is higher, and that of western under developed region is lower.
