摘要
研究非期望产出条件下不同职能城市土地利用效率分异特征及其驱动因素,对于城市可持续发展具有重要意义。本文采用DEA中改进的EBM模型,测度了2004—2015年中国五大类268个城市的土地利用效率,并运用灰色关联模型探究了其主要驱动因素。结果发现:①忽视城市土地利用过程中的生态负效应,会引起对土地利用效率的高估,而考虑非期望产出,能更加真实地测算出土地利用效率;各职能城市的土地利用效率均存在较大差异,说明按城市职能类型来测度土地利用效率的科学性。②在不考虑非期望产出条件下,各职能城市的土地利用效率值曲线相对陡峭且周期性变化较多,而在考虑非期望产出条件下,效率值曲线变化相对平缓且周期性变化较少。③综合型城市主要受产业结构、土地市场化程度和环境治理能力的影响,资源型城市主要受产业结构、对外依赖程度和政府规制的影响,工业型城市主要受产业结构、土地市场化程度和地区能源结构的影响,文娱型城市主要受城镇化水平、经济发展水平和环境治理能力的影响,地方型城市主要受经济发展水平、城镇化水平和政府规制的影响。鉴于此,在提升城市土地利用效率时,应充分考虑土地的非期望产出和城市的异质性,制定出差异化的土地管理政策。
Studying the differential characteristics and driving factors of land use efficiency in different functional cities under the condition of undesirable outputs has great significance for urban sustainable development. This paper applied the improved EBM model in DEA to measure land use efficiency for 268 Chinese cities across five categories. Grey correlation modeling was used to explore the main driving factors of land use efficiency. We found that ignoring ecologically negative effects leads to an overestimation of land use efficiency. Land use efficiency of each functional city was different, proving that the measurement was scientific in terms of city function type. Land use efficiency curves were relatively steep and had periodic variation without considering the undesirable output while this curve became relatively gentle and had less periodic variation when taking the undesirable output into consideration. The main driving factors of land use efficiency in different functional cities contain significant differences. For integrated cities these driving factors included industrial structure, degree of land marketization and capacity of environmental governance; for resource-based cities they were industrial structure, external dependence, government regulation, industrial structure; for industry-based cities they were the degree of land marketization and regional energy structure; for entertainment-based cities they were the level of urbanization, economic development and capacity of environmental governance; for local cities it was mainly affected by the level of urbanization, economic development and government regulation. We need to fully consider the undesirable output and city heterogeneity in order to improve urban land use efficiency and determine different land management policies.
