Abstract: How to optimize the spatial structure of China's city clusters in the new era has become a strategic issue that matters to the overall situation. Based on Marx's capital accumulation theory, this paper explores the nature and tendency of capital that tries to overcome all spatial hindrances in order to identify the general law in the spatial structure evolution of city clusters. At the same time, taking into account the Chinese context, it incorporates the role of government into the theoretical framework, systematically explains the evolution dynamics of the spatial structure of China's city clusters, and deepens the theoretical understanding of the city cluster development model with Chinese characteristics. In addition, by considering the changing contradictions in the evolution of the spatial structure of China's city clusters, and properly addressing the interactions between an effective government and an efficient market in this evolution, this paper comes up with a theoretical logic for optimizing the spatial structure of China's city clusters, which weakens the risk of polarization that may result from capital accumulation. Finally, given the major contradictions in the spatial structure evolution and the development level of city clusters in different regions, this paper proposes differentiated development paths for optimizing the spatial structure of city clusters in different regions in China.

摘要： 新时代中国城市群的空间结构优化问题已经成为事关全局的战略性问题。本文以马克思资本积累理论等为基础，通过分析资本力求攻克一切空间阻碍的本性与趋势来发现城市群空间结构演化的一般规律，同时结合中国情境，将政府作用等因素纳入该理论分析框架，系统阐释了中国城市群空间结构演化的动力机制，深化了对中国特色城市群发展道路的理论认识。此外，通过把握中国城市群空间结构演化矛盾的变化、妥善处理有为政府与有效市场在城市群空间结构演化过程中的互动关系，来梳理中国城市群空间结构优化的理论逻辑，削弱了资本积累所可能导致的两极分化风险。最后，本文还针对不同地区空间结构演化主要矛盾、城市群发育程度等具体情况，确定了中国不同地区城市群空间结构优化的差异化发展路径。
