Carbon Emission Pattern of China's Tourism Transportation and Its Influencing Factors.

Carbon emission of tourism transportation is one of the important factors leading to global climate change. It is of great social and economic significance to study the spatial differences and influencing factors of tourism transportation carbon emission. This paper takes 30 provincial administrative regions in China as the basic research units, then, based on the construction of measurement model for carbon emission of tourism transportation, and uses the spatial variogram, trend surface analysis and spatial measurement models, to explore the spatial and temporal pattern evolution and influencing factors of tourism transportation carbon emission. It is found as follows. 1) In the period of 2005 to 2018, the carbon emission of China's tourism transportation shows a continuous increase trend, in which the absolute difference of tourism transportation carbon emission increases gradually, and the relative difference shows the characteristics of periodic fluctuation. 2) The overall spatial differentiation of tourism transportation carbon emission is significant, showing a trend of decreasing from east to west. This is basically consistent with China's "strong east and weak west" tourism network pattern, the spatial characteristics of tourist passenger flow and direction which are along the main traffic trunks and aviation hubs. 3) There are spatial interactions and linkage effects in the carbon emissions of provincial tourism transportation in China. In general, the spatial difference tends to increase in the east-west direction, while the spatial differentiation in other directions is small. 4) The regional economic development level, the openness to foreign tourism and scale of tourists are the main factors leading to tourism transportation carbon emission. To a great extent, this has shaped the regional differentiation pattern of the carbon emission of China s tourism transportation, and the development level of service industry, tourism resource, energy intensity and energy structure have various degrees of inducing or inhibiting effects.
