Study on the Influencing Factors of Population Size in China Mega-Cities

Abstract

It is of great significance for urban planning and management to identify the influencing factors on population size. We collect the data of resident population and its influencing factors in China four municipalities from 1997 to 2016 to establish a fixed effect model. The urban population size and its influencing factors are analyzed from the angle of cost and income. The results suggest that the wage level, the development of the second and third industries, and the medical level are the main income factors to promote population growth. In addition, the intensity of environmental pollution is the main cost factor to restrain population growth. However, there is a significant positive relationship between the real estate price and the urban population size, perhaps the population size growth causes the real estate prices rise.
