An extensive and profound investigation into the dynamic interactions between High‐Quality Urbanization (HQU) and Ecosystem Service Value are of utmost importance for the coordinated development of the region. Diverging from traditional macro‐level analysis, this study is grounded on county‐scale data, measuring HQU and ecosystem service value from a multidimensional perspective. On the basis of the research framework of “phenomena‐relationships‐mechanisms”, we expect to delve deeper into the spatio‐temporal evolutionary characteristics of ecosystem service value and HQU and their integrated interactions. Additionally, we utilize econometric models to rigorously evaluate the impact of HQU on ecosystem service value, with the goal of filling the current research gaps. The research results are as follows: (1) From 2000 to 2020, the ecosystem service value in Shandong Province exhibit an overall decreasing and then increasing trend, and shows a spatial posture of high east and low west. HQU generally maintains a steady upward trend, and its spatio‐temporal evolution has apparent heterogeneity. (2) The Coupled Coordination Degree (CCD) between HQU and ecosystem service value has a gradual rising trend, and there is an increasing level of consistency between them. (3) HQU has a negative effect on ecosystem service value, and the direction and degree of the effect on segmented ecosystem service value types vary greatly. (4) The effect of HQU on ecosystem service value is heterogenous, and the attenuating effect is mainly found in grain‐producing counties, inland counties, and counties with a lower index of high‐quality urbanization. In conclusion, our results are expected to provide targeted recommendations for sustainable development and ecological balance in Shandong Province.

山东省高质量城镇化与生态系统服务价值动态互动与机制：趋势、协调及其对可持续发展的启示

广泛而深入地研究高质量城镇化与生态系统服务价值之间的动态相互作用对于区域协调发展至关重要。与传统的宏观分析不同，本研究以县域数据为基础，从多维度的角度衡量HQU和生态系统服务价值。我们期望在“现象-关系-机制”的研究框架基础上，深入探讨生态系统服务价值与HQU的时空演化特征及其综合相互作用。此外，我们利用计量经济学模型严格评估HQU对生态系统服务价值的影响，以填补当前的研究空白。研究结果如下：（1）2000—2020年，山东省生态系统服务价值整体呈现先减小后增大的趋势，并呈现东高西低的空间态势。 HQU总体保持稳定上升趋势，其时空演化具有明显的异质性。 (2)HQU与生态系统服务价值的耦合协调度(CCD)呈逐渐上升趋势,两者之间的一致性程度不断增强。 （3）HQU对生态系统服务价值产生负向影响，且对细分生态系统服务价值类型的影响方向和程度差异较大。 （4）HQU对生态系统服务价值的影响存在异质性，衰减效应主要表现在产粮县、内陆县和城镇化质量指数较低的县。总之，我们的研究结果有望为山东省的可持续发展和生态平衡提供有针对性的建议。
