Particulate matter 2.5 is air pollution that affects human health and negatively affects the economy. This study investigates the impacts of particulate matter 2.5 on the number of international tourists arriving in Chiang Mai. We employ the test kink effect and panel kink regression to examine the nonlinear relationship between variables. The data set used in our study is quarterly data from January 2012 to December 2018. The empirical results show that an increase in particulate matter 2.5 leads to a decrease in foreign tourists.
