在当前我国旅游产业地位不断提升、县域经济面临转型升级的大背景下,本文基于县域经济高质量发展的视角,立足全国旅游综合实力百强县的评选,对全国旅游综合实力百强县的建立如何提高县域绿色全要素生产率(Green Total Factor Productivity, GTFP),促进经济绿色转型,进行深入研究。本文选取2008~2022年浙江省52个县及县级市的面板数据进行分析。首先通过包含非期望产出的超效率Slacks-Based Measure (SBM)模型,结合Global-Malmquist-Luenberger (GML)指数模型测度县域绿色全要素生产率(GTFP);其次利用全国综合实力百强县政策这一准自然实验,运用多期双重差分法模型,考察该政策对县域绿色全要素生产率(Green Total Factor Productivity, GTFP)的影响,探究产业结构升级的调节作用。研究表明:1) 旅游产业发展显著推动了县域经济高质量发展,这一结论在多项稳健性检验后仍然成立;2) 产业结构升级在旅游产业发展对县域经济高质量发展的影响中发挥正向调节作用。In the current context of the rising status of China’s tourism industry and the transformation and upgrading of the county economy, this paper is based on the perspective of high-quality development of the county economy, based on the selection of the top 100 counties of the national tourism comprehensive strength, and the establishment of the top 100 counties of the national tourism comprehensive strength of how to improve the county’s Green Total Factor Productivity and promote the green transformation of the economy, to conduct an in-depth study. This paper selects the panel data of 52 counties and county-level cities in Zhejiang Province from 2008 to 2022 for analysis. Firstly, the county green total factor productivity (GTFP) is measured by the super-efficiency Slacks-Based Measure (SBM) model that includes non-desired outputs, combined with the Global-Malmquist-Luenberger (GML) index model;Secondly, the quasi-natural experim
