Analysis On The Coupling Coordinated Development And Influencing Factors Of Population Urbanization And Land Urbanization In Sichuan Province

Since the beginning of reform and opening up,Chinese urbanization level has developed rapidly,but the rapid development of urbanization has neglected the improvement of quality and exposed the problem of internal uncoordinated urbanization,and in the urbanization process,population urbanization and land urbanization are its two important factors.Sichuan Province is at an important stage of urbanization development,but the development process of urbanization is also facing the problem of uncoordinated development,and the quality and speed of urbanization still need to be further optimized and improved.Therefore,it is important to study the coordinated development of population and land in Sichuan Province for the healthy,coordinated and sustainable development of urbanization in Sichuan Province.By studying the temporal and spatial differences of population urbanization level,land urbanization level,comprehensive urbanization level and coupling coordination degree as well as the influencing factors in Sichuan Province,it is concluded that the overall urbanization development level in Sichuan Province shows a rising trend between 2010 and 2020.However,there are differences in the annual growth rates.There are obvious regional spatial differences in urbanization levels in Sichuan Province,with Chengdu as the core and decreasing to the peripheral areas in a "coreedge" structure.According to the level of urbanization,the 21 cities(states)are divided into the following 6 echelons: Chengdu is the only city in the first echelon.The second echelon includes Panzhihua,Deyang and Zigong,which have better resource conditions themselves.The third echelon includes Suining,Leshan,Yibin,Mianyang,Neijiang and Luzhou,with convenient transportation.The fourth echelon includes Nanchong,Guang’an,Meishan and Ya’an,four cities that are far from the main urban core cities.The fifth echelon includes Guangyuan,Bazhong,Dazhou and Ziyang,which are remote,have poor natural environment and are relatively lagging behind in infrastructure construction.The sixth echelon includes Ganzi Tibetan Autonomous Prefecture,Aba Tibetan and Qiang Autonomous Prefecture,and Liangshan Yi Autonomous Prefecture,which have large ethnic and cultural differences coupled with the distance from the core cities,and are not prominent in the development of Sichuan Province.The type of coupling and coordination among urbanization subsystems in Sichuan,in terms of time,is dominated by the moderate coordination zone,while the high coordination zone has been only Chengdu and the dysfunctional decline zone has been only Ganzi Tibetan Autonomous Prefecture.With the growth of time and the continuous improvement of urbanization level,Sichuan province has achieved more remarkable results in the coordinated urban-rural development.Spatially,the highest degree of coordination between population urbanization and land urbanization coupling has been Chengdu,which is in high coordination;only Ganzi Tibetan Autonomous Prefecture is in the dysfunctional recession area;Aba Tibetan and Qiang Autonomous Prefecture and Ganzi Tibetan Autonomous Prefecture are in the transitional coordination area;Guangyuan,Mianyang,Suining,Deyang,Meishan,Ya’an,Leshan,Zigong,Neijiang,Yibin,Luzhou,and Panzhihua are better developed and in the moderate coordination zone;Nanchong,Guang’an and Zigong fluctuate between the moderate coordination and transition coordination zones.The nine influencing factors of openness,population density,fiscal revenue,fiscal expenditure,investment in fixed assets,financial scale,domestic trade,basic pension insurance for urban workers,and basic urban medical insurance have an economic contribution to the degree of coordinated development of population urbanization and land urbanization;the three influencing factors of urban-rural income gap,industrial structure,and infrastructure constrain the coordination development of population and land urbanization in Sichuan Province.The three influencing factors of urban-rural income gap,industrial structure,and infrastructure constrain the coordination development of population and land urbanization in Sichuan.
