摘要
随着城镇化的不断发展,建设用地对经济发展瓶颈作用日益凸显,为合理利用土地资源、优化土地利用结构,探讨土地对经济增长贡献率,以吉林省9个地级市（州）为研究对象,利用C-D函数,对其2004-2011年的建设用地贡献率进行测算,并用ArcGIS 10.0进行聚类,探讨其空间差异及原因。结果表明：1建设用地对经济增长的贡献率在14.05%~55.47%,且存在明显的区域差异,其区域差异主要与自然环境、社会经济条件相关;2建设用地投入对经济社会发展有重要支撑作用;3今后要不断优化产业结构,转变经济增长方式,走科技创新型和资本、资源集约型道路。
With continuous development of urbanization in China, the bottleneck of construction land in economic development has become increasingly prominent. For the purpose of rationally utilizing land resources, optimizing land use structure and investigating the contribution of land to economic growth, this paper measures the contribution rate of construction land from 2004 to 2011by means of the C-D function with nine cities （states） of Jilin Province as the object of study, and clusters with ArcGIS10.0 to investigate the spatial differences and reasons and to propose countermeasures. The results show that （1） The contribution rate of construction land to economic growth is between 14.05% and 55.47%, with obvious regional differences, and the regional difference is mainly related to the natural environment and social economic conditions; （2） The construction land input has an important supporting role to the economic and social development; and （3） It is necessary to constantly optimize the industrial structure, change the mode of economic growth, and take the road of innovation of science and technology and capital intensive, resource-intensive.
