研究问题
A parallel literature on spatial equity examines whether public facilities are distributed fairly relative to need, emphasizing accessibility as the mechanism through which location translates into use ( 10–12 ).；The present study positions provincial bed supply within this geographical frame: it treats the spatial allocation of older adult care facilities as an equalization problem, asks whether provincial differences are spatially structured or spatially random, and tests whether the equalization process has altered that structure.；Whether such dependence is present is an empirical question that the spatial tests below address directly.
方法
Three considerations argue for treating it as an upper bound: the marginal Hansen statistic; the fact that bed supply is a slow-moving stock, so that a three-year half-life is difficult to reconcile with construction and planning cycles; and the closeness of the GMM rate to the sub-period cross-sectional rates (23–27%), which are themselves inflated by the short horizons over which they are computed.；Read together, the full-sample cross-sectional rate of 9.3%, the sub-period rates of 23–27% and the GMM rate of 23% bracket the true speed; the robust conclusion is that convergence is present and economically substantial, not that it proceeds at any particular rate.；Fourth, the 2018 revision changed statistical coverage unevenly across provinces; sub-period estimation mitigates but cannot fully eliminate its effects on cross-sectional comparisons that straddle 2017–2018.
核心结论
These studies enrich the spatial picture but stop short of formal convergence analysis, and their samples end before the recent period in which, as we show, the regional hierarchy reversed.；Taken together, the global and local results establish Proposition P2 and add a spatial dimension to the convergence story.；Timing is the most important: our data run to 2023, and the reversal is a post-2018 phenomenon.
局限
Because policy-defined belts may not coincide with the spatial structure of the data, we complement the belt analysis with contiguity-based spatial statistics that let neighborhood effects and cross-border similarity emerge from the data themselves.；Section 6 discusses mechanisms, policy implications and limitations, and Section 7 concludes.
