Spatial and Temporal Variation and Fairness of Urban Amenities in Jiangsu Province

The Urban Amenities Evaluation Index provides the possibility of comparison between different cities and brings new ideas for the study of talent mobility and development. Based on the existing researches, this paper improves the amenities system, and takes 13 cities in Jiangsu Province as the research objects. It calculates the urban amenities index and urban amenities intensity of each city from 2007 to 2017, analyzes the spatial pattern changes, time and space differences, amenities balance and attraction of talents. The results show that: ① In 2007–2017, amenities index generally showed an upward trend, the volatility increased in the past 6 years, while the emission intensity showed a significant downward trend, but the decline slowed down year by year. ② The amenities space has obvious clustering characteristics, and the high amenities index area gathers in the southern part of Jiangsu. The strength of the amenities also gradually appears in the north high south low and the west high east low partition differences. ③ Amenities development is relatively average. ④ The amenities effect shows obvious regional differences: “High-high” type is located in the central and eastern parts of Jiangsu Province and Xuzhou City; “low–high” type gathers in the southern parts of Jiangsu Province; “high-low” type includes the northern parts of Jiangsu Province except Xuzsshou; the “low-low” type assembles in the southwestern parts of Jiangsu Province, which is radiated by Nanjing. This paper analyzes the time and space differences and effect clustering of urban amenities, which not only provides scientific basis for the development of urban development goals in Jiangsu Province, but also offers new ideas for regional researches of talent attraction and high-tech industry development.
