Planetary boundaries as spatial constraints: rethinking regional development under ecological limits
指出经济地理学很少将生态限制视为区域发展的硬约束，重新将行星边界定义为空间差异化的约束，揭示非线性限制、不均衡暴露和负担转移如何重塑发展轨迹、挑战趋同假设并产生新的区域不平等和空间冲突，为人类世下的可行性和治理研究提出议程。
Abstract Economic geography has increasingly engaged with environmental change, yet ecological limits are rarely treated as binding constraints on regional development. This article argues that planetary boundaries remain underexplored in economic geography and reframes them as spatially differentiated constraints that define region-specific ecological feasibility. This perspective shows how non-linear limits, uneven exposure, and burden shifting reshape development trajectories, challenge assumptions of convergence, and generate new forms of regional inequality and spatial conflict. It also outlines an agenda for research on feasibility and governance in the Anthropocene.
