Abstract:

Green development in tourism transportation industry represents both a new breakthrough for the advancement of high-quality tourism development and a significant embodiment of ecological civilization construction. Accordingly, this study takes the Lanzhou City, a critical transportation hub city in western China, as a case study, employing the entropy weight method and the DEA-Malmquist index model to measure and evaluate the green development efficiency of the tourism transportation industry of Lanzhou from 2014 to 2023. The following findings were obtained: (1) In terms of spatiotemporal evolution, temporally, the comprehensive environmental cost index of Lanzhou’s tourism transportation industry demonstrates a downward trajectory, which is accompanied by enhanced green development efficiency and a generally positive development trend. In a spatial sense, the green development efficiency of tourism transportation industry in Lanzhou’s main urban areas follows a distribution pattern in which Anning District displays the highest efficiency, followed sequentially by Xigu District, Qilihe District, and Chengguan District. (2) Using the Malmquist index decomposition results, the total factor productivity of Lanzhou’s tourism transportation industry experienced slow overall growth, with Chengguan District registering the least growth and Qilihe District achieving the most. The research results can provide a reference for optimizing the green development of the tourism transportation industry in Lanzhou City and promoting regional ecological protection.

Key words: green development efficiency, tourism transportation industry, DEA-Malmquist index model, Lanzhou City
