城市作为现代化的核心空间载体，其发展质量的空间分异受到多重维度因素的驱动。本文从先天禀赋与后天努力两个维度出发，基于2000—2022年中国283个城市数据，运用地理探测器方法，探究二者对城市发展质量空间分异的影响及其作用机制。研究发现：城市发展质量空间分异受先天禀赋与后天努力双重驱动，且二者互为增益，后天努力通过制度优化发挥先天禀赋的优势；区域异质性分析表明，先天禀赋对中部和东北地区影响最为明显，后天努力对东部地区影响最为明显；时间异质性分析表明，在“质量元年”后，先天禀赋与后天努力的影响力及交互作用显著增强。因此，应充分发挥先天禀赋与后天努力的协同作用，推动城市空间治理优化和区域协调发展。本研究为中国特色城市现代化建设提供了理论基础与政策建议。

As the core spatial carrier of modernization, the spatial differentiation of urban development quality is driven by multi-dimensional factors. This paper examines urban development conditions from two dimensions: innate endowment and acquired effort. Based on panel data for 283 Chinese cities from 2000 to 2022, and employing the geographic detector method, this paper investigates the effects of these two factors on the spatial differentiation of urban development quality and their underlying mechanisms. It is found that, spatial differentiation in urban development quality is jointly driven by innate endowment and acquired effort, with the two exerting mutually reinforcing effects. Acquired effort, through institutional optimization, enables the advantages of innate endowment to be effectively realized. Regional heterogeneity analysis indicates that innate endowment has the most pronounced impact in Central and Northeast China, while acquired effort plays a more significant role in Eastern China. Temporal heterogeneity analysis shows that after the “Year of Quality, ” both the effects and the interaction between innate endowment and acquired effort have significantly strengthened. Therefore, greater emphasis should be placed on leveraging the synergistic effects of innate endowment and acquired effort to promote the optimization of urban spatial governance and regional coordinated development. This study provides a theoretical foundation and policy implications for urban modernization with Chinese characteristics.
