中文摘要：

着眼于城市群发展系统的复杂动态关系，建立了包含城市群经济增长和城市群空间结构特征的系统动力学模型。通过数据仿真研究城市群经济增长与城市群空间结构演化之间的关系，并调整政策变量集合得到3种城市群空间结构演化模式，比较发现，空间结构呈现位序～规模分形分布的城市群空间结构演化模式最利于促进城市群经济增长，而且投资、城市间相互作用和城市群创新能力对城市群经济增长起重要作用。城市群发展规划中应防止城市群空间结构分形特征退化，并且增强城市间相互作用和城市群创新能力以促进城市群健康发展。

英文摘要：

With a view to the complex dynamic relation of urban agglomeration development system, the thesis studied the relations of Guanzhong urban agglomeration economy growth and its urbanization progress by using system dynamics （SD） model according to the historical data simulation, and found fractal characteristics of size distribution of Guanzhong urban agglomeration raising continuously in the future. By comparing the three projects that were simulated in the model through adjusting policy variables, the thesis forecasted that the hierarchical size structure that presents the Rank-Size Rule development pattern was more propitious to accelerate the urban agglomeration ＇ s economic growth than other development patterns. The thesis found investment, interaction among cities and innovation ability of urban agglomeration played an important role in the economic development. Thus, the fractal characteristics degeneration of urban agglomeration should be prevented and the interaction among cities and the innovation ability of urban agglomeration should be strengthened by urban agglomeration development planning in order to facilitate the sound development of the urban agglomeration.
