环渤海地区沿海城市旅游生态效率时空分异及收敛性研究

Spatial and temporal differentiation and convergence studies of tourism eco-efficiency of coastal cities in Bohai Rim region

旅游生态效率是衡量旅游经济发展好坏的重要标准,随着环渤海地区旅游的迅速发展,生态问题日益凸显。因此以环渤海地区14个沿海城市为研究对象,分别采用超效率SBM-DEA模型、Dagum基尼系数分析方法等,实证分析环渤海地区旅游生态效率时空分异及收敛性问题。结果表明:(1)环渤海地区旅游生态效率水平整体发展态势良好,但区域之间发展不平衡。(2)该地区旅游生态效率差异水平在逐渐减小,其空间差异来源主要是超变密度差异。(3)三大区域以及整体旅游生态效率存在“追赶效应”,各城市之间旅游生态效率差距在逐渐缩小。

Tourism ecological efficiency is an important standard to measure the development of tourism economy.With the rapid development of tourism around the Bohai Sea area,ecological problems have become increasingly prominent.Therefore,taking 14 coastal cities around the Bohai Sea as research objects,the super-efficiency SBM-DEA model and dagum Gini coefficient analysis method were used to empirically analyze the spatio-temporal differentiation and convergence of tourism eco-efficiency in the Bohai Sea rim region.The results show that:(1)the overall development trend of tourism eco-efficiency in the Bohai Rim region is good,but the development is unbalanced among regions.(2)The difference level of tourism eco-efficiency in this region is gradually decreasing,and the main source of the spatial difference is the super-variable density difference.(3)There is a"catch-up effect"in the three regions and the overall tourism eco-efficiency,and the gap between tourism eco-efficiency among cities is gradually narrowing.
