摘要
从1990-2010年长三角城市土地利用效率的时空变化特征出发,对不同类型城市建成区扩张与经济增长之间的协整关系及格兰杰因果关系进行了研究。结果表明,长三角城市土地利用效率呈上升趋势,但区域差异较为明显;不同类型城市的建成区扩张与经济增长之间均存在长期稳定的协整关系,但两者之间的格兰杰因果关系在不同城市间的差异较大,上海、南京的经济增长与建成区扩张之间存在双向和单向因果关系并存的现象,经济增长已明显步入转型期,而杭州、无锡的经济增长却仅是建成区扩张的单向格兰杰原因,经济增长仍过度依赖于建设用地的扩张,土地利用方式不太合理。因此,应有效地转变经济发展方式,推行差别化的土地供应调控和供后监管政策,以实现城市可持续发展。
In this essay the spatial and temporal variations of urban land - use efficiency in Yangtze Delta Area are analyzed to study the co - integration relationship and granger cause relationship between urban expansion and economic growth. Results show that: the urban land -use efficiency shows an upward trend, but regional differences are more obvious. There is long - term stable co - integration relationship between the urban expansion and economic growth, of which have great differences in granger cause relationship among the different cities of Yangtze Delta Area. The both bidirectional and unidirectional granger cause relationships between urban expansion and economic growth are coexisted in both of Shanghai and Nanjing, which have clearly entered in the economies transition. On the contrary, the economic growth is only unidirectional granger cause of builtup area expansions in Hangzhou and Wuxi, whose economic growth is still overly dependent on the expansion of construction land with unreasonable land use. Therefore, in order to achieve sustainable urban development, the mode of economic growth should be effectively changed, at the same time, differential land supply policy and land regulatory policy should be implemented.
