土地资源错配对城市蔓延的影响研究基于成渝地区双城经济圈的面板数据分析

Research on the Influence of Land Resource Mismatch on Urban SprawlA Panel Data Analysis Based on Chengdu-Chongqing Economic Circle

  • 摘要: 城市空间的蔓延扩张深刻影响着经济社会的高质量发展。探究城市蔓延原因,对于成渝地区双城经济圈的建设和西部大开发新格局的形成有着重要意义。但地方官员在财政分权和官员晋升机制的双重激励下,往往对工业用地和商服用地采取差异化供地策略,使得土地资源在不同行业之间扭曲配置,城市空间结构也随之发生变化。本文以成渝地区双城经济圈2009—2017年的面板数据为基准,通过静态面板模型和动态面板模型的实证研究表明,土地资源在不同行业的错配会带来城市空间的扩张蔓延。研究还发现,城市蔓延存在动态持续变化的特征,即前一期的城市蔓延对当期的城市蔓延存在正向效应。最后,文章从建设用地跨区域占补平衡、土地利用效率等方面提出了相关政策建议。

     

    Abstract: The sprawl and expansion of urban space has a profound impact on the high-quality development of the economy and society. To explore the causes of urban sprawl is of great significance to the construction of the Chengdu-Chongqing twin-city economic circle and the formation of a new pattern of western development. However, under the dual incentives of fiscal decentralization and official promotion mechanism, local officials often adopt a differentiated land supply strategy for industrial land and commercial land, resulting in a mismatch of land resources between different industries, and changes in the urban spatial structure. Based on the 2009-2017 panel data of Chengdu-Chongqing Twin-city economic circle, an empirical study of static panel model and dynamic panel model shows that the distorted allocation of land resources in different industries will bring about the expansion and sprawl of urban space. The study also finds that urban sprawl has dynamic and continuous changes: the previous urban sprawl has a positive effect on the current urban sprawl. Finally, the paper puts forward relevant policy recommendations in terms of cross-regional balance of construction land and land use efficiency.
