Given its adverse health effects, particulate matter (인터넷 바카라) pollution has become a critical public policy issue in Northeast Asia. As concerns about 인터넷 바카라 pollution increase, so does the interest in identifying its origins, including trans boundary pollutant sources. Employing the daily average 인터넷 바카라10 concentration level data from Beijing, Shanghai, and Seoul in 2014–2016, we estimate the direction and extent of the spillover effect of the 인터넷 바카라10 density between China and Korea. Estimation outcomes suggest that the 인터넷 바카라10 density levels in Beijing and Shanghai are Granger causes of the 인터넷 바카라 density in Seoul, but not vice versa.That is, the 인터넷 바카라 10 density in Seoul increased by 0.13 and 0.133 p인터넷 바카라 in response to the 1p인터넷 바카라 increase in the 인터넷 바카라10 density in Beijing and Shanghai on the previous day, respectively.The cross-border spillover effect from Beijing decreased by 0.076 p인터넷 바카라 from May to October when the air flow hindered the 인터넷 바카라10 sources generated in Beijing from reaching Seoul.
