The Allocation of Responsibilities in Air Pollution: Evidence from Ethnic Minority Urban Agglomerations

Abstract

Abstract. This paper constructed AQI hourly & monthly index to make a comparison based on the high-frequency AQI data and major pollutants statistical data of four ethnic minority urban agglomerations, then established a VAR model to analyze the Variance Decomposition. The results indicated that the air pollution of four urban agglomerations had exhibited noticeable seasonal effect and clustering feature. Once there was a deterioration of air quality in one city, the other neighboring cities would spread it rapidly but decayed slowly. According to the results of the Variance Decomposition, whose orders was determined by the average velocity to the peak of the impulse response function, a scheme was proposed in this paper to solve the issues in the allocation of responsibilities for regional joint prevention in each city.
