Does the location of construction land supply play an very important role on economic growth? The case study of Tianjin Binhai New Area

摘要

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.
