【摘要】 在大城市区域化与区域城市化快速发展背景下，“同城化”作为区域一体化发展的高阶形式，理论与实践均处于起步阶段。论文基于适应度景观理论及NK模型，构建了包括经济同步度、空间向心度、交通联通度、设施链接度、公服互惠度与生态共保度6个评价维度、18个综合指标的指标体系，以及量化评价方法，并对中国既有的20个大城市地区同城化案例进行实证分析。结果表明：NK模型可以有效测度同城化发展水平及其关键要素的差异，当前中国主要大城市地区同城化发展水平可划分为成熟型、成长型与萌芽型3种类型，不同类型地区同城化形成机制与优化路径具有差异。基于NK模型的大城市地区同城化发展水平评价方法为同城化发展水平测度提供了全新工具，研究结果可为同城化发展战略与政策制定等提供有益参考。更多还原

【Abstract】 Against the backdrop of rapid metropolitan regionalization and regional urbanization, urban integration as an advanced form of regional integrated development remains in the initial stage both theoretically and practically. Based on the Fitness Landscape Theory and the NK model, this study constructed an evaluation indicator system covering six dimensions and 18 comprehensive indicators, as well as a quantitative evaluation method. The six dimensions include economic synchronization, spatial centripetalism, transportation connectivity, facility linkage, public service reciprocity, and ecological co-conservation. An empirical analysis was carried out on 20 urban integration cases in China’s metropolitan areas. The results show that the NK model can effectively measure the development level of urban integration and the differences of its key influencing factors. The current development level can be classified into three types: mature, growing, and emerging, with distinct formation mechanisms and optimization paths among different types. The evaluation method based on the NK model provides a new tool for measuring urban integration development level, and the findings can provide useful references for formulating urban integration development strategies and policies.更多还原
