城市新增建设用地扩张影响机制: 基于 PSR 框架的组态分析

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.
