2.4 Evaluation of urbanization
level
2.4.1 Selection of urbanization
indicators
Referring to some related literatures (such as Liu, 2018; Li, 2021), we
constructed an urbanization assessment system based on the entropy value
method from four aspects (Table 2). The comprehensive UI system
coordinates with 4 primary indicators and 10 secondary indicators.
Population urbanization (PU) is the baseline of urbanization
development, which is characterized by the population density and the
urban population proportion. As the core content of urbanization
development, economic urbanization (EU) is characterized by GDP,
secondary and tertiary industries proportions, and total fixed asset
investment. Spatial urbanization (SU) is characterized by urban road
area and urban construction land proportions. Social urbanization (SCU)
denates the diffusion of civilization and the level of people’s living
standards, enriching the connotation of urbanization, and is
characterized by average wage of staff and workers employed in urban
units and total sales of social consumer goods.
