3.1.1. Modeling

The empirical analysis in this paper was based on the following analysis framework, as shown in Figure 1. This paper first used the Super-SBM model to calculate tourism's carbon emission efficiency (TCEE) of the Yellow River Basin from 2010 to 2019. Secondly, the entropy method and linear weighting were used to comprehensively evaluate the tourism economy's high-quality development (TEHQD). Finally, taking tourism's carbon emission efficiency (TCEE) and the tourism economy's high-quality development (TEHQD) as the symbiosis unit, the symbiosis degree model was used to reflect the correlation degree of their mutual influence. The symbiosis coefficient was used to measure the mutual influence degree between the two, and the geographical detector was used to explore the driving factors and obstructive factors affecting the symbiosis development of the two to construct an interactive mechanism model of tourism's carbon emission efficiency (TCEE) and the tourism economy's high-quality development (TEHQD).
