不断深入的行政体制改革使府际关系日益成为理论界和实务界所共同关心的热点问题。随着科技活动复杂性的提升和行政体制改革的不断深化,科技创新政策领域跨部门合作愈加频繁与复杂,国家科技行政主管部门与中央其他部门的横向协同进一... 不断深入的行政体制改革使府际关系日益成为理论界和实务界所共同关心的热点问题。随着科技活动复杂性的提升和行政体制改革的不断深化,科技创新政策领域跨部门合作愈加频繁与复杂,国家科技行政主管部门与中央其他部门的横向协同进一步增强。本研究以1978~2013年的中国中央部门联合行文的1298份科技政策文献为数据,以1978以来国务院六次大规模的机构改革作为时间节点,对科技政策领域政府部门的合作关系进行分阶段考察,绘制出不同阶段政府部门合作网络图,定量分析了不同阶段政府部门合作关系的整体网特征、局部网特征和单节点子网特征。研究发现:(1)中国科技政策府际合作在数量上呈现出由少到多的趋势,在范围上呈现出由小到大的趋势,在复杂性上呈现出由简单到复杂的趋势;(2)少数行政部门形成核心合作关系,科技部、财政部、发改委在科技政策的制定中逐渐形成了“铁三角”的关系;(3)科技主管部门和产业主管部门的合作关系日益密切,反映出产学研政策结合度不断提高。最后,研究基于责任与利益两个维度,对府际合作关系分类进行了讨论,指出推进政府部门间合作关系从其他类型向协作型府际合作关系转变是在中央政府层面推进国家治理体系和治理能力现代化的必由之路。 展开更多

Objective Through bibliometrics and visual analysis of the related studies on traditional Chinese medicine(TCM)treatment of immune thrombocytopenia(ITP),this study aims to sort out the overall research progress,hotspots,and trends in this field,and provide reference for further research in ITP.Methods The articles on ITP treated by TCM were retrieved from China National Knowledge Infrastructure(CNKI),Wanfang Database,China Science and Technology Journal Database(VIP),Web of Science Core Collection(WOSCC),and PubMed.The retrieval time was from the establishment of the databases to July 31,2022.VOSviewer,CiteSpace,Carrot2,and Note-Express were used for data analysis of the articles in terms of their quantities,types,and journals,and for visualization of research hotspots,authors,institutions,and keywords.Results 1493 Chinese articles and 40 English articles were included.The articles in Chinese mainly focus on clinical trial research and clinical experience summary,while the English articles mainly focus on clinical trial research and animal research.The Chinese articles were published in 317 Chinese journals,while English articles were published in 29 English journals.Research hotspots include the clinical syndrome differentiation of ITP,the therapeutic effect of TCM compounds on ITP,and the mechanism of ITP treatment.Keyword analysis shows that there are many research achievements in integrated traditional Chinese and western medicine treatment,clinical research,famous doctors’experience,TCM treatment,cellular immunity,and humoral immunity.The authors with the most articles in Chinese and English are Professor CHEN Xinyi and Professor MA Rou,respectively,and the research institutions with the most articles are Dongzhimen Hospital of Beijing University of Chinese Medicine and Xiyuan Hospital of China Academy of Chinese Medical Sciences.Chinese herbs often used to treat ITP clinically include Xianhecao(Agrimoniae Herba),Nvzhenzi(Ligustri Lucidi Fructus),Mohanlian(Ecliptae Herba),Zhongjiefeng(Sarcandrae Herba),etc.,and the prescription usually used to treat ITP include Guipi Decoction(归脾汤),Xijiao Dihuang Decoction(犀角地黄汤),Bazhen Decoction(八珍汤),Erzhi Pill(二至丸),and Xiaochaihu De-coction(小柴胡汤).The main development trends toward retrospective study,TCM treatment mechanism,and data mining. 展开更多

As an important foundation for promoting social progress and economic development, natural resources play an important role in the sustainable development of cities. However, the increasing demand of human beings for natural resources has led to various ecological environmental problems, such as excessive population density, serious environmental pollution, the continuous decline of total natural resources and per capita resources, all of which have hindered sustainable development. Therefore, the study of natural resources and sustainable development has become the focus of many current scholars. In this paper, CiteSpace is used as an analysis tool to analyze the literature on natural resources and sustainable development over the past 20 years. First of all, this paper deeply analyzes the research status of this field in terms of academic research trends, authors and research institutions, co-occurrence of keywords, etc., and on this basis, it then deeply analyzes its evolutionary path and research hot spots in the past 20 years through keyword emergence. Finally, according to the visualization of the analysis results, the future development trends of this research field are speculated:(1) Grasp the current research focus;(2) Improve the research accuracy;(3) Enrich the theoretical system of research;and(4) Establish an interdisciplinary research system. 展开更多
