In recent years, the content and direction of China’s local protection presents a new trend. Some scholars have car⁃ried out a literature review on this field. However, there are few researches on employing bibliometric method to summarize and position the literature. This paper, based on the literature sources from journal database of China National Knowledge In⁃ternet (CNKI), by means of CiteSpaceⅢsoftware, using the bibliometric method with the combination of common word analy⁃sis, cluster analysis and strategic coordinate analysis, sorts out and analyzes the research status, research hotspot and new re⁃search direction of local protection from 1981 to 2015, and explores the development trend of Chin’s local protection research. The results show that:“local government”study“regional economy”,“monopoly”and other issues are the main focus of local protection research, and the“emerging industries”,“subsidies”,“regional economic growth”and“comprehensive deepening reform”are relatively new research contents. The number of papers by Chen Huai, Yu Donghua, Zhao Yongliang and other scholars as well as Renmin University of China, Shandong University, Sun Yat-sen University and other research institutions rank at the top, and the collaboration between the authors and the research institute is not very close. The paper provides some reference for the researchers in this field through knowledge mapping analysis of local protection research in China.%近年来，我国地方保护研究的内容与方向呈现新趋势，部分学者对该领域进行了文献综述，但运用文献计量方法对文献进行归纳和定位的研究较少。文章以中国知网（CNKI）的期刊数据库为文献来源，借助于CiteSpaceⅢ软件，运用共词分析、聚类分析和战略坐标分析相结合的文献计量方法，对我国1981-2015年地方保护研究领域的研究状况、研究热点及较新颖的研究方向进行梳理与剖析，探讨我国地方保护研究领域的发展趋势。结果表明“：地方政府”“、区域经济”、“行业垄断”等问题的研究是我国地方保护研究的主要热点，而“新兴产业”、“补贴政策”、“区域经济增长”、“全面深化改革”则是其中比较新颖的研究内容；陈淮、余东华、赵永亮等学者及中国人民大学、山东大学、中山大学等科研机构的发文量居前；研究作者之间和研究机构之间的合作不太紧密。通过对我国地方保护研究领域进行知识图谱分析，为该领域的研究者提供一定的参考与借鉴。
