Abstract
This study examines the statistical causal relationship between recent chronic decreasing of skiing visitors and global warming. Concretely speaking, paying attention to the number of skiing visitors in Nagano Prefectures from 2006 to 2017, candidates of explanatory variables are extracted by usual OLS with time series data sets of several ski areas. Subsequently, with pooling data for each prefecture, we engage in panel data analysis and decompose it into the factor of climate change and the others. As the results, the annual change rate of skiing visitors due to total factor, the one due to climate change, and the one due to other reasons are -2.95%, 0.46%, and -3.41% respectably for Nagano. These findings show that decreasing of skiing visitors in this term stemmed largely from social reasons other than climate change and that the weather rather mitigated slightly the decline.
