文章以1996-2015年Web of Science数据库收录的大数据领域文献为研究样本，从总体态势、空间格局演变特征和当前研究力量布局三个角度进行了分析。结果显示，大数据领域研究正处于中前期加速发展期，学科交叉性强；研究中心正在向中、美、英、德等多个核心区演变，呈现"核心-边缘"结构，并且各国研发实力相差悬殊，核心区主要发达国家研究力量和影响力稳步增长，而中国及亚洲地区的研究成果产出量增长较快，但研究成果学术质量亟待提升。%The paper is to scan the study characteristics of big data in detail, thereby to provide reference for an in-depth development of big data. The author collects literatures on the subject of big data of Web of Science from 1996 to 2015. The overall trend, space pattern evolvement and distribution of research strengths are analyzed. The results show that the study of big data is stepping into the golden development period, and has a strong interdisciplinary nature. Global research has evolved from America to multiple centers———China, America, England and Germany, and demonstrates a “core-pe-ripheral”structure. And there are wide disparities in countries around the world. The strength and impact of R&D about major developed countries in core areas steadily increase over time, but China still has a way to go.
