【摘要】：一个地区的土地集约利用和经济发展是相互促进的,土地集约利用和经济协调发展是经济社会可持续发展的重要保障。不同经济发展水平的城市其土地集约利用程度也会有很大的悬殊,所以本文选取陕西省10个地市作为研究单元来探讨其土地集约利用和经济发展的时空差异。通过对国内外有关土地集约利用的研究,本文构建了陕西省城市土地集约利用与经济发展水平的因素因子指标体系,运用熵值法确定各指标权重并计算得出陕西省各地市的土地集约利用和经济发展综合评价值,采用协调发展度模型、重心迁移模型和全局自相关分析等方法对陕西省土地集约利用和经济发展的时空差异进行全面剖析并试图探索其差异形成的原因,最后根据研究结论得出促进陕西省土地集约利用和经济协调发展的政策启示。文章主要研究结论如下： (1)陕西省各城市土地集约利用和经济发展水平总体上在不断提高,其中,土地集约利用水平悬殊较大且整体水平不高；经济发展水平极不均衡,整体来看陕北地区经济发展较好,关中次之,陕南最差。随着时间的推移,陕西省城市土地集约利用和经济发展逐渐呈明显的相关性。 (2)陕西省土地集约利用重心轨迹整体向北偏东方向偏移且偏移幅度相对较大；经济发展重心迁移幅度则相对较小,其轨迹持续向北移动。表明陕北地区土地集约利用和经济发展水平都得到显著的提升。 (3)陕西省各城市土地集约利用和经济发展的协调性较差,但是随着时间的迁移其协调性在逐渐增强,逐渐从不同程度的不协调发展过渡到协调发展状态。此外,大多数城市的协调性均表现为土地集约利用滞后于经济发展,土地集约利用度需要得到提升。 (4)陕西省各城市土地集约利用度、经济发展水平以及二者间的协调度在空间上呈现正的或是负的相关性,各城市在空间上的适度集聚效益较弱,辐射带动作用发挥不够。 (5)由于受地形地貌、气候等自然因素以及历史发展基础和政策等因素的影响,使得陕西省经济发展极不均衡,表现出明显的地域特征,加之各区域产业结构、城市人口及规模等因素共同制约着城市土地集约利用水平,因此陕西省土地集约利用水平和经济发展水平呈现出一定的时空差异。为促进陕西省土地集约利用和经济的共同协调发展,必须制定合理的土地利用规划；充分挖掘城市用地潜力,优化土地空间布局；优化产业和用地的结构和分布；推动经济转型,转变经济发展方式；因地制宜,提高陕西省不同地区土地集约利用和经济的整体协调发展水平。
[Abstract]:Intensive land use and economic development in a region promote each other. Intensive land use and coordinated economic development are important guarantees for sustainable economic and social development. The degree of intensive land use in cities with different levels of economic development will also be very wide. So this paper selects 10 cities in Shaanxi Province as research units to explore the space-time difference between intensive land use and economic development. Based on the study of intensive land use at home and abroad, this paper constructs the factor index system of urban land intensive utilization and economic development level in Shaanxi Province. The entropy method is used to determine the weight of each index, and the comprehensive evaluation values of land intensive utilization and economic development in Shaanxi Province are calculated, and the coordinated development degree model is adopted. The barycenter transfer model and global autocorrelation analysis are used to analyze the spatio-temporal differences in intensive land use and economic development in Shaanxi Province, and the reasons for the differences are explored. Finally, according to the conclusions of the study, the policy implications of promoting intensive land use and coordinated economic development in Shaanxi Province are obtained. The main conclusions are as follows: (1) the level of intensive land use and economic development in various cities in Shaanxi Province is increasing, among which, the level of intensive land use is wide and the overall level is not high, and the level of economic development is extremely uneven. Overall, the economic development of northern Shaanxi is better, Guanzhong is second, and southern Shaanxi is the worst. With the passage of time, the intensive use of urban land and economic development in Shaanxi Province gradually showed obvious correlation. (2) in Shaanxi Province, the barycenter track is shifted to the east and north, and the economic development center of gravity migration is relatively small, and its trajectory continues to move northward. It shows that intensive land use and economic development in northern Shaanxi have been significantly improved. 3) the coordination of intensive land use and economic development in Shaanxi Province is poor, but the coordination of land use and economic development is gradually enhanced with the transfer of time, from different degrees of uncoordinated development to coordinated development. In addition, the coordination of most cities shows that the intensive use of land lags behind the economic development, and the degree of intensive land use needs to be improved. 4) the degree of intensive land use, the level of economic development and the degree of coordination between the two cities in Shaanxi Province show positive or negative correlation in space, the moderate agglomeration benefit of each city in space is weak, and the function of radiation driving is not played enough. Due to the influence of natural factors such as landform, climate, historical development basis and policy, the economic development of Shaanxi Province is extremely uneven, showing obvious regional characteristics, and regional industrial structure. Urban population and scale together restrict the level of urban land intensive use, so the level of intensive land use and economic development level in Shaanxi Province presents a certain space-time difference. In order to promote the coordinated development of land intensive utilization and economy in Shaanxi Province, it is necessary to formulate rational land use planning, fully tap the potential of urban land use, optimize the spatial distribution of land, optimize the structure and distribution of industry and land use. To promote economic transformation, to change the mode of economic development, and to improve the level of intensive land use and the overall coordinated development of the economy in different areas of Shaanxi Province according to local conditions.
