Abstract

Abstract:

By analyzing the coordinated development level of population and land urbanization in Jiangsu Province and its three major regions (the south, central and north Jiangsu), we aim to promote the high-quality development of urbanization. By constructing a population and land urbanization evaluation index system, we used the coefficient of variation method and the entropy method to determine the weights and adopted the coupling coordination degree model to study the coordination of population and land urbanization of Jiangsu Province from 2000 to 2018 and that of 13 prefecture-level cities of the province in 2018. The results showed that: (1) the population urbanization index of Jiangsu Province was slightly higher than that of the land urbanization index from 2000 to 2001 and from 2003 to 2013, which was a lagging type of land urbanization; the land urbanization index of Jiangsu Province was higher than that of the population in 2002 and from 2014 to 2018, the urbanization index belonged to the lagging type of population urbanization; (2) the degree of coordination between population and land urbanization in Jiangsu Province was unbalanced (2000 to 2001), of medium-low coordination (2002 to 2004), of moderate coordination (2005 to 2008), of medium-high coordination (2009 to 2012), and of high coordination (2013 to 2018); (3) the lagging space of population and land urbanization in Jiangsu Province presented a ‘north-south’ structure, the level of urbanization in Jiangsu Province was uneven and the phenomenon of polarization was prominent; (4) except Xuzhou City, the coordination degree of population urbanization and land urbanization in Jiangsu Province showed a ‘step-like distribution down from south to north’, Nanjing City had the highest degree of coordination between population and land urbanization, and Suqian City had the lowest degree of coordination. This study obtained the temporal evolution law and spatial pattern characteristics of the population and land urbanization in Jiangsu Province, and stated the direction for the coordinated development of population and land urbanization in the province.

Key words: population urbanization, land urbanization, coordination degree, Jiangsu Province
