优化都市圈的经济空间有助于提升国家的综合竞争力。以京津冀都市圈为例，基于2009年世界银行发展报告中“经济密度”（Density）、“经济距离”（Distance）和“经济整合”（Division）的“3D”视角，应用因子分析法来研究都市圈的经济空间格局。结果表明：京津冀都市圈经济密度呈现一体两翼，经济距离环状递减，经济整合高度集聚，整体为阶梯式发展。最后从公共制度、基础设施建设以及针对性的激励措施等方面提出适应于“3D”特征的城市发展政策。

Optimizing the economic space of metropolitan area can help enhance the coun- try＇ s overall competitiveness. This paper attempts to analyze the economic spatial pattern of Beijing-Tianjin-Hebei megalopolis through factor analysis method from the ＂3D＂（density, distance and division） perspective based on the 2009 World Development Report. The results show that in Beijing-Tianjin-Hebei Metropolitan Region, density is high in the central area and low in the wing areas; distance decreases from the center to the rings; division presents a high concentration, and the overall development feature is like a ladder. Finally we propose the urban development policies in accordance with the ＂3D＂ features, concerning public institutions, in- frastructure construction, as well as targeted incentives.
