| The process of urbanization includes two important components of population urbanization and land urbanization.Which land are the basis and carrier of urban development,people are the core and essence of urban development.At present,China's urbanization has developed rapidly,but there are problems that can't be ignored: on the one hand,urban land expansion is too fast,land use efficiency is low and even blindly reclaimed land to build new city.This will deepen the contradictions between the growing demand for urban land and limited land resources,and thus constrain the city's continued development.On the other hand,China's rural population has a high cost of transferring to cities,difficult to settle down,difficult to become real citizens,and there is serious semi-urbanization.In this context,fully understanding the connotation of population urbanization and land urbanization and the coordinated development relationship between the two has important theoretical significance and practical significance to achieve the healthy and orderly development of the urbanization and the social stability.First of all,based on the connotation of urbanization and urbanization of population,this paper constructs the evaluation index system of urbanization and land urbanization,and then uses the entropy method to measure the comprehensive development level of population urbanization and land urbanization in 30 provinces(municipalities)in China from 2006 to 2015.The results show that:(1)The comprehensive development level of urbanization and land urbanization in the provinces is on the rise;(2)The development gap between the provinces is large and the east is greater than the central part,the central part is greater than the western part.Secondly,the coupling coordination model is used to measure the coupled development level of population urbanization and land urbanization in 30 provinces and cities in China from 2006 to 2015.The results show that:(1)From 2006 to 2015,China's population urbanization and land urbanization coordination level improved but the increase was smaller and overall coordination level was lower;(2)The coordination degree gap between the provinces is large and the east is greater than the central part,the central part is greater than the western part.Then,we use the Moran's I index,Moran scatter plot and LISA agglomeration map to analyze the spatial correlation of the coordinated coordination degree between population urbanization and land urbanization in China from 2006 to 2015.The results show that:(1)The Moran's I index is positive,indicating that there is a positive spatial autocorrelation between the population of the provinces and the coordination degree of land urbanization.(2)Moran I scatterplots show that most of the provinces in China are distributed in the first and third quadrants,suggests that the urbanization coupling coordination degree between population and land among provinces has a spatialagglomeration phenomenon,that is the high level provinces are clustered together with high level provinces,low level provinces are clustered together with low level provinces.Finally,the spatial panel lag model is used to test the influence factors of the coupling coordination degree of China's population urbanization and land urbanization.The results show that: the per capita GDP,the value added of the second industry accounts for the proportion of GDP,the added value of the tertiary industry accounts for the proportion of GDP,urban and rural residents income gap and foreign direct investment have a positive effect on the coupling coordination degree of population and land urbanization,and the coefficient of the value added of the second industry accounts for the proportion of GDP and the added value of the tertiary industry accounts for the proportion of GDP is greater than that the coefficient of other variable;The proportion of government revenue in government revenue plays a negative role in coupling coordination between population and land urbanization. |
