Decoupling China’s Tourism Economy from Carbon Emissions Through Digitalization: A Supply-Side Analytical Framework

Global tourism activities have become increasingly digitalized, yet the economic and environmental impacts of digitalization on tourism remain underexplored. This study develops a supply-side analytical framework to examine whether and how digitalization decouples tourism economy from carbon emissions by integrating Ghosh input-output analysis, subsystem analysis, and structural decomposition analysis. Our findings reveal that digitalization has largely decoupled China’s tourism economy from carbon emissions, with the increases in economic gains notably outpacing those in emission losses. Specifically, the digital-enabled tourism value-added (DTV) increased by approximately 18 times from 2002 to 2017, while digital-enabled tourism emissions (DTE) only grew by about 11 times. Between 2017 and 2020, due to the impact of the COVID-19 pandemic, the DTV decreased by about 61%, and DTE dropped by approximately 63.5%. The expansion in DTV can be primarily attributed to advancements in software and IT services and electronic components, while the increase in DTE is significantly driven by software and IT services and communication services. The growth in digital supply emerged as the predominant driver for the surging DTV and DTE, with the emission intensity of tourism subsectors acting as a notable constraint. This study offers both a methodological framework and empirical evidence aimed at guiding policy initiatives that target the digitalization and low-carbon transition of the tourism sector.
