Effect of tourism development on urban air pollution in China: The moderating role of tourism infrastructure

摘要

Tourism development has become increasingly important in supporting China's sustained economic growth. However, unreasonable tourism exploitation and large energy consumption have brought severe challenges to China's urban environment, particularly for air pollution problems which constrains improvements in sustainable economic development and social welfare. This paper is aim to empirically investigate the direct and spatial spillover effects of tourism development on air pollution in China using panel data from 285 prefecture-level cities from 2005 to 2017. After spatial correlation statistical analysis, this research employs a generalized nested spatial econometric model (GNS) to conduct empirical estimations. The results demonstrate that the tourism development's direct effect on PM2.5 concentrations takes on an inverted U-shaped relationship. In contrast, the indirect effect of tourism development on PM2.5 demonstrates reveals a U-shaped relationship. For industrial SO2 emissions, both the direct and indirect effect of tourism development have inverted U-shape relationships. We find that urban highspeed rail construction and tourism resources play an important moderating role in the relationships between tourism development and urban industrial SO2 emissions. These results confirm a tourism environment Kuznets curve in the context of China, with significant spatial spillover effects from tourism development on air pollution. We conducted two robustness tests and then offer policy suggestions to reduce air pollution. (c) 2020 Elsevier Ltd. All rights reserved.
