【摘要】：城市化发展是世界各国在经济与社会发展中关注的焦点,在这一领域涌现出大量文献和相关研究资料。由于世界各国的国情以及社会发展阶段的差异,国内外城市化发展主题的理论创新以及文献中所展现的核心主题和词汇呈现出截然不同的特点,而科学知识图谱作为文献分析的重要方法,可以直观的显示城市化理论相关文献主题和词汇的发展结构关系,通过对数据库中对应主题的文献时序和被引状况的数据统计,归纳城市化发展这一社会科学领域的国内外研究热点主题和核心词汇,揭示该领域文献研究的发展趋势,对国内外未来城市化发展的前景做出预测和展望。科学知识图谱在城市化发展这一社会科学领域的文献数据统计、知识图谱的可视化研究、以及国内外发展阶段的对比分析方面具备广阔的研究和发展前景。通过对1994-2014年度国内外在城市化发展过程中关于城市化发展研究的文献数据库的图谱分析和文献知识图谱的可视化描述,直观的展现出国内外在城市化发展领域的主题分布及其演变趋势,从中分析基于研究主体的、基于知识图谱研究主题的、以及基于词频分析的国内外城市化主题方向的发展变化,并进一步进行文献分布的成因分析。从中总结出国内外城市化发展研究的核心主题及关键焦点,挖掘城市化研究热点主题,主题发展的趋势与特征及薄弱环节,通过对比分析和图谱的聚类离散度以及时间序列的描述,去探讨城市化发展领域的国内外异同,结合我国与西方发达国家的城市化发展国情,剖析“智库”构成、城市化发展阶段以及国内外学术环境对城市化发展领域文献主题和词频分布的影响,理顺国内外城市化发展脉络,为中国的城市化发展领域的文献研究提供广泛的参考。
[Abstract]:The development of urbanization is the focus of attention in the world in economic and social development. A large number of literature and related research materials have emerged in this field. The theoretical innovation of the theme of urbanization development at home and abroad, as well as the different characteristics of the core theme and vocabulary displayed in the literature, the scientific knowledge map is an important method of literature analysis. It can intuitively show the relationship between the topic of the literature and the development of the lexicon in the urbanization theory, and through the statistics of the literature sequence and the citation status of the corresponding topic in the database, This paper sums up the hot topic and core vocabulary of urbanization, which is a hot topic in the social science field, and reveals the development trend of literature research in this field. The future prospect of urbanization at home and abroad is forecasted and forecasted. The scientific knowledge map in the social science field of urbanization development literature data statistics, knowledge map visualization research, The comparative analysis of the development stages at home and abroad has broad prospects for research and development. Through the atlas analysis and literature analysis of the literature database on urbanization development in the process of urbanization development in China and abroad from 1994 to 2014. Visual description of knowledge maps, The theme distribution and its evolution trend in the field of urbanization development at home and abroad are displayed intuitively, from which the theme based on research subject and knowledge map is analyzed. And based on word frequency analysis, the development and change of urbanization theme direction at home and abroad, and further analysis of the causes of literature distribution, from which the core theme and key focus of urbanization development research at home and abroad are summarized. This paper excavates the hot topic of urbanization research, the trend and characteristics of theme development and weak links, through comparative analysis, cluster dispersion of map and description of time series, to explore the domestic and foreign similarities and differences in the field of urbanization development. Combined with the development of urbanization in China and western developed countries, this paper analyzes the composition of "think tank", the stage of urbanization development and the influence of academic environment at home and abroad on the theme and word frequency distribution in the field of urbanization development. Straightening out the development of urbanization at home and abroad provides a wide range of references for the literature research in the field of urbanization development in China.
