基于DEA模型的辽宁省旅游生态效率研究

Study on tourism eco-efficiency of Liaoning based on DEA model

旅游生态效率是经济发展和环境保护的结合。在发展旅游业的同时,实现生态自然的可持续发展是研究旅游生态效率的目的。本文在前人研究的基础上,通过建立相应的旅游生态效率投入产出指标体系,收集2011-2016年辽宁省各地级市的投入—产出数据,运用Max-DEA软件,对近六年来辽宁省各地级市的旅游生态效率进行评价分析。结果表明:近年来辽宁省整体的旅游生态效率变动幅度较小,基本稳定在0.6-0.9之间,但是各地级市之间的差异较大,其中丹东、盘锦、大连和沈阳近六年来均值最高,铁岭、阜新和葫芦岛旅游生态效率值最低。

Tourism eco-efficiency is a synthesis of economic development and environmental protection.At the same time,to realize the sustainable development of ecological nature is the purpose of studying the eco-efficiency of tourism.Based on the previous research,this paper establishes the corresponding input-output index system of tourism eco-efficiency,collects input-output data from every prefecture-level city in Liaoning province in the past six years by using Max-DEA software.The results show that in recent years,the overall ecological efficiency of tourism in Liaoning province has changed slightly,and it has basically stabilized between 0.6 and 0.9.However,the differences between prefecture-level cities are relatively large.Amongthem,Dandong,Panjin,Dalian and Shenyang have had the highest average in six years.Tieling,Fuxin and Huludao tourism eco-efficiency values are the lowest.
