摘要
以长株潭城市群为研究区域,分别建立土地集约利用及经济发展水平评价指标体系,应用动态计量经济方法与模型研究分析了该区域土地集约利用和经济发展的相互作用关系。结果表明:(1)长株潭城市群的土地集约利用与经济发展水平序列都是一阶单整序列,二者在短时期内存在一定程度的失衡,但长期表现为均衡关系;(2)因果检验发现二者存在较明显的单向因果关系,即土地集约利用的Granger原因为经济发展;(3)二者的脉冲响应分析表明,经济发展对土地集约利用的冲击影响较大、变化响应强烈,其对土地集约利用冲击影响的解释水平达到了95.3%;而土地集约利用对经济发展的冲击影响较小、变化响应微弱,其对经济发展冲击影响的解释水平仅为4.7%。因此,提高土地集约利用水平需进一步加快转变经济发展方式,加强土地利用监督管理,促进区域土地利用与经济协调发展。
Based on the measuring of the degree of economic development and land intensive utilization, the paper explored the interactions between economic development and land intensive utilization by dynamic econometrics. The results showed that economic development and land intensive utilization were integrated into order one. There existed equilibrium relationship between them in long term whereas things were different in short term. Granger causality test showed that economic development was the grange cause of land intensive utilization, but the opposite grange causality couldn＇t be proved by the empirical study. The response of land intensive utilization toeconomic development impulse was remarkable, and the economic development impulse could explain the change of land intensive utilization to a certain extent of 95.3%. The response of economic development to land intensive utilization impulse was weak, and the land intensive utilization impulse could explain the change of economic development to a certain extent of only 4.7%. Therefore, it is necessary to take some measures to improve the level of land intensive use, such as further accelerating the transformation of economic development mode, strengthening the supervision and management of land use, and promoting the coordinated development of regional land use and economic development.
