- Abstract
Urban shrinkage index was calculated with data about the urban population of 250 prefecture-level Chinese cities from 2012 to 2017. In total, 55 shrinking cities were selected. First, the impacts of urban shrinkage on haze pollution were looked into in theory. Second, the spatial distribution and spatial autocorrelation of urban shrinkage were analyzed. Finally, the spatial error model (SEM) and the fully modified least squares (FMOLS) regression were used to empirically examine the impacts of urban shrinkage on haze pollution at national and regional levels, respectively. The results indicated that shrinking cities showed spatial agglomeration, with northeast China having the largest number of shrinking cities. From a national perspective, SEM revealed that urban shrinkage reduced haze pollution. Increase in the proportion of secondary industries, economic development and built-up areas intensified haze pollution, while increase in green area in parks reduced such pollution. From a regional perspective, except for west China, the impacts of urban shrinkage on haze pollution were significantly negative. Urban shrinkage in central China had the greatest impacts on haze, followed by northeast and east China. Haze pollution was intensified by the increase in the proportion of secondary industries in east, central and west China, alleviated by economic development in east and west China, slowed down by the increase in green area in parks in northeast, east and west China, and aggravated by the rise in built-up areas in northeast, central and west China. Targeted suggestions were proposed to reduce haze pollution, adapt to urban shrinkage and build quality small cities based on local conditions.
