Abstract Land is not only a basic factor of production and an important space carrier, but also a key tool to control the development of urban economy. While the phenomenon of land participation in regulation exists generally in China, the theory of supporting regulation and the effect of regulation are still unclear. In the study, we intend to analyse the relationship between location of construction land supply and regional economic growth. By constructing indexes of construction land supply structure and a theoretical model based on the Solow model, we explore the relationship between the location of construction land supply and economic growth in the Tianjin Binhai New Area (TBNA). We find that the location of construction land supply significantly impacts economic growth. The circle-layers dimension has a hop about the influence of construction land supply on economic growth. The orientation dimension has superiority in some regions, especially the southwest and northwest. To realise sustainable urban development, construction land supply should focus on the lag and location difference of its economic driving effect and actively promote the redevelopment of stock construction land not only in the TBNA but also other rapidly developing cities.

建设用地供应区位对经济增长的影响是否很大？天津滨海新区案例研究

摘要 土地不仅是基本的生产要素和重要的空间载体，也是控制城市经济发展的关键工具。虽然我国普遍存在土地参与调控的现象，但支持调控的理论和调控效果尚不明确。本研究拟分析建设用地供给区位与区域经济增长的关系。通过构建建设用地供给结构指标和基于索洛模型的理论模型，探讨天津滨海新区建设用地供给区位与经济增长的关系。我们发现建设用地供应区位显着影响经济增长。圈层维度对建设用地供给对经济增长的影响存在跳跃性。方位维度在部分地区具有优势，尤其是西南和西北地区。为实现城市可持续发展，建设用地供给应着眼于其经济带动效应的滞后性和区位差异，积极推动存量建设用地再开发，不仅在滨海新区，而且在其他快速发展的城市。
