碳排放约束下中国旅游业绿色发展效率研究--基于修正三阶段DEA模型

Green Efficiency of China's Tourism Industry——A Modified Three-stage DEA Model Analysis

文章引入非期望因素修正三阶段DEA模型,剔除随机误差和外部环境因素影响,研究2010-2014年中国30个省市旅游业绿色发展效率。实证结果显示,仅东部地区旅游业绿色发展效率达到了最优;其中,东部旅游业绿色发展效率的领先主要来源于配置效率的提高,西部效率没达到最优则主要归因于技术效率的无效率,中部则主要归因于配置效率的无效率。在外部环境因素中,各省城市化水平、绿色交通水平对于旅游业能源利用效率的提高能够起到积极的作用;而各省技术创新水平、对外开放度显示出对旅游业绿色发展效率的负面影响。

Based on the modified three-stage DEA model, the green efficiency of China＇s regional tourism industry from year 2010 to 2014 is studied to figure out the green development efficiency＇s spatial difference and influencing factors. The empirical results show that among the three big areas, only the green efficiency of eastern area has reached the optimal value. Besides, comparatively speaking, the better performance of the eastern area mainly results from its rising allocation efficiency, and the inefficiency of the west area is mainly due to its sub-optimal technical efficiency, while the inefficiency of the middle area is mainly caused by its sub-optimal allocation efficiency. Among the external affecting factors, urbanization level and traffic green level play positive roles for tourism energy efficiency.
