城市新增建设用地扩张影响机制：基于PSR 框架的组态分析

研究目的：基于组态视角探究压力、状态和响应条件对城市新增建设用地扩张（NUCLE）影响的协同和替代效应，为推动城市空间有序治理和完善高质量发展格局下土地调控政策提供参考。研究方法：PSR机理分析和fsQCA法。研究结果：（1）单个压力、状态和响应要素并不构成影响NUCLE的必要条件，不同地区高水平NUCLE的实现是不同PSR条件因素共同作用导致的结果。其中，土地错配、人口规模和经济增长是最具有普遍性的影响因素。（2）压力、状态及响应条件“并发协同”，形成影响NUCLE的多样化组态，具体包括压力主导下多要素平衡型、压力和状态双重赋能型和压力—状态—响应互动型3种差异性模式。（3）在特定的客观禀赋条件下，财政激励和城市化可以通过等效替代的方式影响NUCLE。研究结论：地方政府应根据自身发展特点和资源禀赋，依据压力、状态和响应多重条件的联动匹配效应，“因地制宜”地制定城市新增建设用地规模调控和管理政策。

Exploring the Influencing Mechanism of Newly-added Urban Construction Land Expansion: A Configuration Analysis Based on PSR Framework

The purpose of this study is to systematically explore the synergy and substitution effects exerted by pressure, state and response (PSR) conditions from the perspective of configuration, as this might have an impact on the newly-added urban construction land expansion (NUCLE). The study offers some ideas to enhance spatial management and improve the implementation of land use policies to realize high-quality development. The study employs PSR theoretical analysis and fsQCA to explore the mechanism. The results show that: 1) none of the single PSR conditions is necessary for NUCLE. The variation of PSR conditions can lead to different situations of NUCLE in various areas. Land mismatch, population size and economic growth play universal roles in affecting the high-level NUCLE. 2) The combination of PSR conditions has developed five configurations affecting the NUCLE, which can be summarized to three different modes, including the equilibrium of multi factors under the guidance of pressure conditions mode, the empowerment of pressure and state conditions mode, and the interaction of pressure state and response conditions mode. 3) Against specific objective endowment background, PSR conditions can affect NUCLE in a variety of paths, which may result in similar outcomes. In conclusion, it is recommended that local government should adopt appropriate paths and take targeted measures to implement differentiated management policies and control the scale of newly-added urban construction land according to their own characteristics and resource endowment.
