建设用地过度扩张致经济低效增长的机理

Mechanism of low economic growth caused by construction land expanding

运用面板计量模型、索罗增长模型分析了建设用地过度扩张对经济持续增长能力的影响。结果表明,建设用地扩张带来了建安资本的相应增加,由此显著地拉动了经济增长。在中国目前的区域竞争环境与财税体制安排下,以及金融信贷的支持下,容易产生建设用地过度扩张及建安资本过度投资问题;建设用地过度扩张引起资本产出比增加,令经济增长因缺乏技术进步与效率改善而不具有可持续性。因此,为摆脱资源消耗型经济增长方式,加快进入索罗增长模式的进程,应严控建设用地扩张,以提高经济增长的技术水平,倒逼经济增长方式的转变。

By using Metering Model of Panel Data and Solo Growth Model, this essay explores the mechanism of con- struction land expansion on economic growth so as to promote e- conomic transformation and reduce the input of land resource, providing basis for regulation of land conversion. The result shows that the construction land of construction and installation boosts the economic growth; the expansion brings the increasing investment, which significantly current regional competition en- vironment, the financial and tax system of China and the loan support of financial institutions will be easy to cause excessive construction land expansion and excessive construction and in- stallation investment; the increasing capital output ratio caused by excessive construction land expansion makes economic growth lack of technical progress and efficiency improvement. It is concluded that to get rid of the way of economic growth by resource consumption and to accelerate the process of entering the Solow growth way, construction land expansion should be tightly con- trolled in order to improve the technical level of economic growth, reversely forcing the change of economic growth pattern.
