数字鸿沟降低了旅游生态效率?——基于面板门槛模型的实证研究

Does the Digital Divide Reduce Tourism Eco-Efficiency?—An Empirical Study Based on the Panel Threshold Model

基于线性面板模型和面板门槛模型,采用2008~2017年中国省级面板数据,实证检验了数字鸿沟对碳排放的线性和非线性影响。实证结果显示:采用线性面板模型结果表明,现阶段我国数字鸿沟降低了地区旅游生态效率,产业结构、对外开放和数字化程度提升加强了旅游生态效率。考虑门槛效应时,数字鸿沟对旅游生态效率的影响存在双门槛,即三阶段上数字鸿沟对旅游生态效率的抑制作用不同,当地区数字鸿沟处于低水平时,抑制作用较小,数字鸿沟达到中高规模时,抑制作用在增强,旅游生态效率降低。

Based on the linear panel model and the panel threshold model, and using China’s provincial panel data from 2008 to 2017, this paper empirically tests the linear and nonlinear effects of the digital divide on carbon emissions. The empirical results are as follows. The results of the linear panel model show that the digital divide in my country has reduced the ecological efficiency of regional tourism at this stage. The industrial structure, opening to the outside world, and increasing digital-ization have enhanced tourism ecological efficiency. When considering the threshold effect, there are two thresholds for the impact of the digital divide on tourism eco-efficiency. That is to say, the digital divide has different inhibitory effects on tourism eco-efficiency in the three stages. When the regional digital divide is at a low level, the inhibitory effect is small. When the digital divide reaches a medium-to-high scale, the inhibitory effect increases and the tourism eco-efficiency decreases. According to the research conclusions, clarifying the relationship between the digital divide and tourism eco-efficiency is helpful to formulate the digital transformation development strategy of re-gional tourism, and even provide decision-making basis for the high-quality development of region-al tourism.
