Evaluations on social network analysis (SNA) research in China's Mainland:A critical assessment of journal literatures

Social network analysis(SNA) has been introduced to China's Mainland since the end of last century. It is often stated that SNA research has experienced rapid growth in China over these years, but few studies have been conducted to prove the statement. This paper aims at exploring the research status and development of SNA in China by a critical assessment of journal articles. Our findings show that SNA is an evolving and diversified research area which has rich themes and topics, and can be applied to those studies on different levels, context and disciplines, and attract researchers and scholars from various fields and domains. In addition, the information community(Library & Information Science and Information Systems) plays a leading role in the SNA related researches. The paper also points out the research on SNA in China has some limitations, so it proposes several implications for the future development of SNA research from perspectives of information science.

A comparative study of information diffusion in weblogs and microblogs based on social network analysis

Purpose: This paper intends to explore a quantitative method for investigating the characteristics of information diffusion through social media like weblogs and microblogs.By using the social network analysis methods,we attempt to analyze the different characteristics of information diffusion in weblogs and microblogs as well as the possible reasons of these differences.Design/methodology/approach: Using the social network analysis methods,this paper carries out an empirical study by taking the Chinese weblogs and microblogs in the field of Library and Information Science(LIS) as the research sample and employing measures such as network density,core/peripheral structure and centrality.Findings: Firstly,both bloggers and microbloggers maintain weak ties,and both of their social networks display a small-world effect. Secondly,compared with weblog users,microblog users are more interconnected,more equal and more capable of developing relationships with people outside their own social networks. Thirdly,the microblogging social network is more conducive to information diffusion than the blogging network,because of their differences in functions and the information flow mechanism. Finally,the communication mode emerged with microblogging,with the characteristics of micro-content,multi-channel information dissemination,dense and decentralized social network and content aggregation,will be one of the trends in the development of the information exchange platform in the future.Research limitations: The sample size needs to be increased so that samples are more representative. Errors may exist during the data collection. Moreover,the individual-level characteristics of the samples as well as the types of information exchanged need to be further studied.Practical implications: This preliminary study explores the characteristics of information diffusion in the network environment and verifies the feasibility of conducting a quantitative analysis of information diffusion through social media. In addition,it provides insight into the characteristics of information diffusion in weblogs and microblogs and the possible reasons of these differences.Originality/value: We have analyzed the characteristics of information diffusion in weblogs and microblogs by using the social network analysis methods. This research will be useful for a quantitative analysis of the underlying mechanisms of information flow through social media in the network environment.

Evolution and Governance of the Structure of Marine Economic Networks in China’s Coastal Areas: Based on Sea-related A-share Listed Companies

Data on discrete,isolated attributes of the marine economy are often used in traditional marine economic research.However,as the focus of urban research shifts from internal static attributes to external dynamic linkages,the importance of marine economic net-work research is beginning to emerge.The construction of the marine economic network in China’s coastal areas is necessary to change the flow of land and sea resources and optimize regional marine economic development.Employing data from headquarters and branches of sea-related A-share listed enterprises to construct the marine economic network in China,we use social network analysis(SNA)to discuss the characteristics of its evolution as of 2010,2015,and 2020 and its governance.The following results were obtained.1)In terms of topological characteristics,the scale of the marine economic network in China’s coastal areas has accelerated and expan-ded,and the connections have become increasingly close;thus,this development has complex network characteristics.2)In terms of spatial structure,the intensity of the connection fluctuates and does not form stable development support;the group structure gradually becomes clear,but the overall pattern is fragmented;there are spatial differences in marine economic agglomeration radiation;the radi-ation effect of the eastern marine economic circle is obvious;and the polarization effect of northern and southern marine economic circles is significant.On this basis,we construct a framework for the governance of a marine economic network with the market,the government,and industry as the three governing bodies.By clarifying the driving factors and building objectives of marine economic network construction,this study aims to foster the high-quality development of China’s marine economy.

Structural Characteristics and Influencing Factors of Carbon Emission Spatial Association Network:A Case Study of Yangtze River Delta City Cluster,China

City cluster is an effective platform for encouraging regionally coordinated development.Coordinated reduction of carbon emissions within city cluster via the spatial association network between cities can help coordinate the regional carbon emission management,realize sustainable development,and assist China in achieving the carbon peaking and carbon neutrality goals.This paper applies the improved gravity model and social network analysis(SNA)to the study of spatial correlation of carbon emissions in city clusters and analyzes the structural characteristics of the spatial correlation network of carbon emissions in the Yangtze River Delta(YRD)city cluster in China and its influencing factors.The results demonstrate that:1)the spatial association of carbon emissions in the YRD city cluster exhibits a typical and complex multi-threaded network structure.The network association number and density show an upward trend,indicating closer spatial association between cities,but their values remain generally low.Meanwhile,the network hierarchy and network efficiency show a downward trend but remain high.2)The spatial association network of carbon emissions in the YRD city cluster shows an obvious‘core-edge’distribution pattern.The network is centered around Shanghai,Suzhou and Wuxi,all of which play the role of‘bridges’,while cities such as Zhoushan,Ma'anshan,Tongling and other cities characterized by the remote location,single transportation mode or lower economic level are positioned at the edge of the network.3)Geographic proximity,varying levels of economic development,different industrial structures,degrees of urbanization,levels of technological innovation,energy intensities and environmental regulation are important influencing factors on the spatial association of within the YRD city cluster.Finally,policy implications are provided from four aspects:government macro-control and market mechanism guidance,structural characteristics of the‘core-edge’network,reconfiguration and optimization of the spatial layout of the YRD city cluster,and the application of advanced technologies.

Decoding rural connections:A comparative insight into social network analysis in rural communities of China and beyond

Social Network Theory and methods have emerged as pivotal tools for dissecting intricate interdisciplinary issues in rural communities.This study aims to systematically delineate the application characteristics and trends of Social Network Analysis(SNA)in rural community research.Using a twofold approach,we integrate a traditional literature review and CiteSpace bibliometric analysis to assess the application status and evolutionary trends of SNA methods in this context.The key findings include the following:①Chinese research trends:scholars predominantly concentrate on the“three rural”issues(related to agriculture,rural areas,and small-scale farmers)and social support mechanisms for vulnerable rural populations.With policy shifts,rural revitalization,tourism,governance,social trust,and multi-dimensional poverty are poised to emerge as hot topics for the future.For further refinement,we suggest that the application of SNA in rural community research could benefit from content expansion,long-term studies,and innovative modelling techniques.②Research by international scholars has been primarily directed toward the physical and mental health of rural residents,as well as socioeconomic issues.Despite these studies covering a range of typical cases across various nations,a conspicuous lack of thorough,systematic,and prolonged efforts focused on rural community development in specific regions remains.Additionally,health issues affecting rural residents are expected to sustain long-standing and focused international academic attention.This study contributes to a more nuanced understanding of the current applications and potential future directions of SNA in rural community studies,both in China and internationally.

基于SNA的科学计量学领域作者互引网络分析

总体来讲，作者之间的引证关系可以大致分成共被引、耦合和互引三个方面。其中，作者共被引分析自1981年被引入之后，便在探讨学科结构及其研究现状和趋势方面产生了极为广泛的应用。后来，2008年作者耦合概念的提出和实证探索又为学者利用耦合关系研究学科前沿、揭示学科知识结构提供了进一步发掘的空间。在作者互引方面，还多集中在基于引用认同和引证图像的引证行为本身的描述，而对于作者引证关系背后所隐含的知识交流、作者研究相关度、学术共同体发现等方面却没有过多的涉及。针对以上问题，笔者将以科学计量学领域内的核心作者为实证对象，在作者互引关系研究方面作出进一步系列的探索，以期对科学计量学的发展和引文分析的深入应用提供参考，其中本文主要利用社会网络分析方法对科学计量学领域作者互引关系及其网络结构进行深入探索，从互引角度为作者研究相关性、学术地位及知识交流情况提供一定的启示，从而也为后续研究做好铺垫。
