摘要探究城市空间的低密度蔓延通过土地资源错配路径对集聚经济的影响,对于厘清城市蔓延以及土地错配症结的所在和未来集聚经济的发展方向有着重要意义。以全国228个地级市为样本,本文运用中介效应模型,实证检验了城市蔓延通过土地资源错配路径对集聚经济的影响。实证研究发现:(1)城市蔓延对集聚经济存在负外部效应,城市蔓延导致城市边界的大规模扩张,城市的经济密度下降,交通拥堵和环境污染问题的突显,弱化了集聚效应,从而抑制集聚经济;(2)土地资源错配对城市蔓延影响集聚经济存在部分中介效应:城市蔓延会导致土地资源的错配,大规模占用耕地,造成土地闲置和土地利用低效,且土地资源的错配会影响要素和资源的自由流动,进而抑制集聚经济,降低城市生产率;(3)集聚经济受到固定资产投资、就业密度等多方面因素的"驱动"。未来实现城市高质量发展,要转换城市发展模式,创新制度供给,优化土地的配置效率,纠正土地资源错配,进而降低城市蔓延对集聚经济的负效应。 Exploring the impact of low-density urban sprawl on agglomeration economy through land resource mismatch is of great significance to clarify urban sprawl,the crux of land mismatch and the future direction of agglomeration economy.Taking 230 prefecture-level cities in China as samples,this paper empirically examines the impact of urban sprawl on agglomeration economy through land resource misallocation using the mediation effect model.Empirical studies show that:(1)urban sprawl has negative external effects on agglomeration economy,urban sprawl leads to large-scale expansion of urban boundaries,decrease of urban economic density,traffic congestion and environmental pollution,which weakens the agglomeration effect and thus inhibits agglomeration economy;(2)mismatch of land resources has partial intermediary effects on urban sprawl and agglomeration economy.Urban sprawl will lead to misallocation of land resources,large-scale occupation of arable land,resulting in idle land and inefficient land use.Misallocation of land resources will affect the free flow of elements and resources,thereby inhibiting agglomeration economy and reducing urban productivity.(3)The agglomeration economy is driven by many factors such as investment in fixed assets and employment density.In order to achieve high-quality urban development in the future,it is necessary to change the mode of urban development,innovate the system supply,optimize the efficiency of land allocation,correct the misallocation of land resources,and then reduce the negative effect of urban sprawl on agglomeration economy.
