摘要:
[目的] 对浙江省城乡土地利用效率及耦合关系演变进行研究,为实现区域可持续、内生性高质量发展提供决策支持。[方法] 通过构建3阶段DEA模型对2006—2018年浙江省69个县(市、区)的城乡土地利用效率进行测度和评价,在此基础上利用耦合协调模型探讨城乡土地利用效率的协调水平及其时空演变特征。[结果] ①浙江省的城乡土地利用效率差距明显,规模水平是土地利用效率的主要影响因素;②各县(市、区)的城市用地效率水平差距小,而农用地效率的空间极化特征显著;③2006—2018年浙江省城乡土地利用的效率耦合度与协调度波动上升,城乡耦合度与协调度受取决于农业用地效率水平;④城乡土地利用效率协调度区域差异明显。[结论] 浙江省城乡土地利用效率受外部环境影响大,加强乡村建设,提高农用地效率是实现城乡协调,达到高质量发展的关键。

Abstract:
[Objective] The coupling relationships of land use efficiency between urban and rural areas were explored in order to provide decision support for sustainable, endogenous and high-quality development of the region. [Methods] By building a three-stage DEA (data envelopment analysis) model to measure and evaluate the urban-rural land use efficiency of 69 counties (cities and districts) in Zhejiang Province from 2006 to 2018, and using the coupling coordination model, the paper explored the coordination level of urban and rural land use efficiency and their spatio-temporal evolution characteristics. [Results] ① The urban-rural land use efficiency was obviously different across Zhejiang Province, and the scale level was the main influencing factor of land use efficiency; ② The urban land use efficiency among counties (cities and districts) was not significantly different, while the spatial polarization of agricultural land use efficiency was significant. ③ From 2006 to 2018, the coupling and coordination degree of urban-rural land use efficiency in Zhejiang Province showed a fluctuating ascending trend, depending on the level of agricultural land use efficiency. ④ There are obvious regional differences in the coordination degree between urban-rural land use efficiency. [Conclusion] The urban-rural land use efficiency in Zhejiang Province is greatly affected by the external environment, and improving agricultural land use efficiency is the key to realize urban-rural coordination and high-quality development.
