基于主体功能区的福建省城镇建设用地利用效率研究

区域的功能定位对城镇建设用地利用效率存在重要的影响。论文以福建省优化开发区、重点开发区、农产品主产区、重点生态功能区四大功能区功能定位发展目标为基础,采用地均投入产出技术效率表征城镇建设用地利用效率,剔除非期望产出构建随机前沿生产函数模型,对福建省2009—2015年四大主体功能区城镇建设用地利用效率进行差异化评析。结果表明：1）福建省2009—2015年城镇建设用地利用效率有所提升,且存在显著的区域差异。优化开发区城镇建设用地利用效率最高,而农产品主产区最低;农产品主产区城镇建设用地利用效率增速最快,而优化开发区增速最慢,表明建设用地利用程度与主体功能区功能定位存在一致性。2）福建省各主体功能区内要素投入产出存在显著空间分异,且呈现高低值格局之分。根据不同功能定位的区域城镇建设用地利用效率特点提出针对优化对策和建议。

Urban Construction Land-use Efficiency Evaluation Based on the Plan for Major Function-oriented Zones in Fujian Province

The territorial orientation exerts significant influences on urban construction land-use efficiency. Based on the blueprint of major function-oriented zones, the paper analyzed urban construction land-use efficiency indicated by land input-output technical efficiency of the major function-oriented zones in Fujian Province during 2009-2015 by utilizing the stochastic frontier production function which excluded the undesired output. The empirical results demonstrated that: There exists an obvious temporal variation and spatial differences of urban construction land-use efficiency among the 84 counties in Fujian Province during 2009-2015. The index of urban construction land-use efficiency increased during the period that the land-use efficiency indices in almost half of counties were below 0.8 in 2009 whereas the proportion cut down to 30% in 2015. The counties with high urban construction land-use efficiency are spatially distributed in the Quanzhou Plain and Minzhong Mountain Belt. Furthermore, the paper showed that the territorial orientation of major function-oriented zones is consistent with the construction land-use level. The consistency was verified by the following facts: Firstly, cities which located in optimal development zones are most efficient in terms of construction land-use efficiency, while cities in agricultural production zones are most inefficient. The urban construction land-use efficiency grew fastest in agricultural production zones and grew slowest in optimal development zones. Secondly, owing to the different demands of each major function-oriented zone, the input-output ratio of production factors in major function-oriented zones of Fujian Province presented an obvious peak and valley spatial pattern. The input-output ratios of optimal development zone, key development zone, key ecological function zone, agricultural production zone are in decreased order. What’s more, the paper put forward countermeasures and suggestions to optimize the urban construction land-use efficiency according to the spatial difference of land use in different major function-oriented zones in Fujian Province.
