效率-公平耦合导向下的欠发达地区国土空间资源配置

[Objective] Severe conflicts between efficiency and equity are observed in the utilization of territorial space resources in underdeveloped regions. Optimizing the allocation of territorial space resources not only serves as the foundation for regional sustainable development but also provides a scientific reference for promoting the efficient utilization of territorial space. [Methods] Taking the Tiandeng County, Ningming County, and Tian'e County in Guangxi as the research areas, and constructs a four-dimensional analysis framework covering the different regional characteristics. The CRITIC-entropy weight method and the Boston matrix coupling coordination model were used to quantitatively measure the coupling coordination mechanisms between efficiency and equity in territorial space resource allocation in these three counties from 2015 to 2023. [Results] (1) The coupling coordination degrees of the three counties showed significant gradient differences. Tiandeng County had a coupling coordination degree of 0.38, falling within the “low efficiency-low equity” mildly imbalanced range, indicating inefficient land use and insufficient public service supply under the traditional agricultural model. Ningming County reached 0.59, located in the “high efficiency-low equity” transitional coordination interval, revealing that efficiency improved during industrialization while ecological equity lagged behind. Tian'e County achieved 0.64, within the “low efficiency-high equity” primary coordination interval, highlighting significant ecological conservation effectiveness but weak economic transformation capacity. (2) The conflict between efficiency and equity manifested differently in the“production-living-ecological” spaces. In the production space, it was characterized by the contradiction between land intensification degree and industrial adaptability. In the living space, it was reflected in the unequal public services. In the ecological space, it focused on the imbalance between conservation costs and benefit distribution. [Conclusion] The “efficiency-equity” dual-objective measurement model can effectively reflect inter-county and dimensional differences. The feasibility of multidimensional coordination is verified through differentiated strategies, providing theoretical support for territorial spatial planning in underdeveloped regions.
