基于SCIE的胃肠病学及肝脏病学的计量统计分析

Statistical analysis of gastroenterology and hepatology based on SCIE

目的分析胃肠病学及肝脏病学的整体发展状况和我国在该领域的全球地位、发展趋势与发达国家之间的差距及造成这些差距的原因。方法运用文献计量学的方法,对SCIE数据库收录的2000年-2011年胃肠病学及肝脏病学的论文进行统计分析。结果胃肠病学及肝脏病学学科发展已趋于成熟,文献数量进入线性增长阶段。美国、日本等国家是该领域的领军者,中国是该领域发展最快的国家。中国在文献绝对数量、被引频次、高影响因子文献数等方面与美国、日本相比仍存在较大差距。领域内科研机构和科研工作者数量相对较少、国际合作欠缺、资金资助力度不足等是造成差距的可能原因。结论中国在胃肠病学及肝脏病学领域已取得长足进步,但仍需通过客观与主观两个方面的努力来提升我国在该领域的地位。

Objective To analyze the global development of gastroenterology and hepatology discipline, the status of China, the gap as well as its underlying reasons between China and senior countries. Methods The method of biblio- metrics was used to search and analyze the SCI articles in the discipline of gastroenterology and hepatology printed from 2000 to 2011. Results The development of gastroenterology and hepatology discipline was prone to be mature, in which the number of article entered into the linear growth phase. The United States and Japan are the leader, while Chi- na is the fastest growing country in the field. For the article number, cited frequency, and number of article with high- impact factor, China is not comparable to the United States and Japan. The lack of scientific research institutions, scien- tific workers, international cooperation and grant funding may have contributed to the gap between China and the senior countries. Conclusion A great advancement has been achieved in the gastroenterology and hepatology discipline by China. However, both the objective and subjective efforts should be made to improve the development status of China in the field.
