武陵山片区旅游经济—生态效率时空分异及影响因素

Temporal and Spatial Differentiation of Tourism Economy-Ecological Efficiency and Its Influencing Factors in Wuling Mountain Area

旅游生态效率研究已成为旅游可持续发展研究的新方向。以武陵山片区为研究对象,采用DEA方法,测度了研究区域旅游经济—生态效率,结果表明区域综合效率整体水平较低,两极分化严重,但非均衡性趋于逐渐减小;MI指数显示效率在研究期内整体处于较快发展阶段,时序形态呈现“S”形。采用ESDA方法研究要素时空分异特征,全局相关性显示为“聚集—随机—聚集过程”,呈“U”字型变化趋势;局部相关指数显示总体空间关联较弱,呈现从极化趋于均衡的变化趋势。构建了影响因子分析模型,结果表明研究要素受经济因子影响较大,生态环境因素影响较小;经济因子对经济较为发达地区影响弱于欠发达地区,生态因子对经济较发达地区影响强于欠发达地区。

The study of tourism ecological efficiency has become a new direction of tourism sustainable development.Taking Wuling Mountain Area as the research object,DEA method was used to measure the regional tourism economyecological efficiency.The results showed that the overall level of regional comprehensive efficiency was low,the polarization was serious,but the non-equilibrium tended to decrease gradually.MI index shows that the efficiency is in a rapid development stage as a whole during the research period,and the timing pattern is in the shape of"S".ESDA method was used to study the spatial and temporal differentiation characteristics of the elements.The global correlation was shown as"aggregation-random-aggregation process",showing a"U"-shaped change trend.The local correlation index shows that the overall spatial correlation is weak and tends to be balanced from polarization.The influence factor analysis model was established,and the results showed that the research factors were greatly affected by economic factors,while the ecological and environmental factors were less.Economic factors have less influence on economically developed regions than less developed regions,and ecological factors have more influence on economically developed regions than less developed regions.
