国外城市群联动研究综述与展望

城市群联动直接影响并决定了区域空间联系的模式、路径与绩效。基于WoS数据库，运用CiteSpace软件对国外有关城市群联动的主要文献进行了分析和综述，发现研究者对城市群联动发展的认识表现出由实践到理论的多元化与深刻化的特征，对城市群联动的演化趋势及其联动模式的探索成为城市群联动（尤其是多中心城市群联动）研究与实践中的重要内容。研究视角主要表现为城市群联动的阶段演化划分较清晰合理、主题路径集中且主路径突出、前沿趋势聚焦明确、联动模式符合实际并具有一定程度的可复制性等；研究设计主要从方法使用、指标确定以及数据测量等方面进行述评；研究方法大都偏重于设计并建构相关指标进行实证研究等。

Research review and prospect of the linkage of urban agglomerations in foreign countries

The linkage of urban agglomerations directly affects and determines the mode, path and performance of regional spatial connection. Based on Web of Science database, this paper analyzes and summarizes the main literatures about the linkage of urban agglomerations in foreign countries by using CiteSpace. It is found that foreign scholars' understanding of the linkage development of urban agglomerations shows the characteristics of diversification and profundity from practice to theory. The exploration of the evolution trends and linkage patterns of urban agglomerations has become the linkage of urban agglomerations (especially the polycentric urban agglomerations linkage) important content in research and practice. The research perspective mainly shows that the stage evolution division of urban agglomeration linkage is clear and reasonable, the theme path is concentrated and the main path is prominent, the frontier trend is focused clearly, and the linkage mode conforms to the reality and has a certain degree of replicability. The research design is mainly reviewed from the aspects of method use, index determination and data measurement. Most of the empirical research methods focus on the design and construction of relevant indicators.
