Regional differences and pattern evolution of carbon productivity in China's tourism industry
Based on panel data on tourism and related industries for 30 Chinese provinces from 2008 to 2019,this paper uses tourism consumption stripping coefficients,spatial autocorrelation models and spatial lag models to analyze the differences in carbon productivity in China's tour-ism industry over time and space and the factors influencing them.The research shows:(l)From 2008 to 2019,the overall carbon productivity of China's tourism industry has shown an increas-ing trend.However,the spatial distribution is uneven,generally showing the spatial pattern of high in the east and low in the west,and there is a trend of expansion to the middle and west.(2)There is a strong positive spatial autocorrelation in the carbon productivity of China's tourism in-dustry,and the agglomeration in the local space is stronger than the heterogeneity.The"hot spot"areas(H-H type)are mainly adjacent to the eastern coastal areas,while the"cold spot"ar-eas(L-L type)are mainly located in the central and western regions.(3)The degree of economic development,technological innovation and market size have a significant negative effect on car-bon productivity in tourism,and government intervention has a non-significant negative effect and industry structure has a non-significant positive effect.Finally,we propose countermeasures to improve the carbon efficiency of China's tourism industry.
