Many teachers and students of applied economics attended the lecture. The lecture was presided over by Associate Professor Zhang Lingxiang.

　　Professor Zhang Peng's paper uses county-level inversion intensity data as an exogenous source of medium-term air pollution to assess the impact of air pollution on immigrants.The article found that between 1996 and 2010, independent changes in air pollution in China could reduce migration inflows by 50%, and reduce the population of a county by about 5% through net removal.The paper also found that immigration caused by air pollution mainly occurred in the higher education level, young people and women. After the report, Professor Zhang Peng and the teachers and students of the meeting had a heated exchange and discussion on the content of the report, the reading methods of English documents, and the methods of data collection and analysis.
