| The report of the 19 th National Congress of the Communist Party of China puts forward the new requirements for the coordinated development of urban and rural areas in the new era.It is required that while promoting the high-quality development of cities and towns and implementing the strategy of rural revitalization,efforts should be made to promote the coordinated development of cities and villages and gradually realize the integration of urban and rural development.Sichuan is a major province in economy,population and agriculture,it is also a one strategic hub to support one belt,one road and the Yangtze River economic belt.It plays an important role in the pattern and process of regional and urban-rural coordinated development.At the same time,the circulation channels of urban and rural population,capital,technology and other elements need to be further unblocked.There is a large gap in the construction of urban and rural roads,communications and other infrastructure between cities(prefectures),and there are also obvious differences in the development of urban and rural residents’ income and consumption capacity,which has become one of the important challenges facing the coordinated and high-quality development of urban and rural areas in Sichuan Province.Under the new era background of promoting the modernization of national governance system and governance capacity,this paper makes a comparative study on the urban-rural development coupling coordination of 21 cities(prefectures)in Sichuan Province,analyzes its temporal and spatial characteristics in recent years,and finds out the different practical problems faced by the coordinated development of urban and rural areas in different regions.On this basis,it puts forward the policy suggestions of regional classification guidance to promote the relative level of Urban-Rural Coordination The promotion of the coordinated development level in low areas is of great practical significance to further promote the overall promotion of the coordinated development level of urban and rural areas in Sichuan Province,and to establish and improve the system and mechanism of urban and rural integration development.Therefore,focusing on the research theme of "spatial-temporal differentiation of urban-rural development coupling coordination degree in Sichuan Province",this paper selects 2012-2017 as the key research period,focusing on the following three aspects: first,what are the characteristics of time sequence changes of urban-rural development coupling coordination degree in 21 cities(prefectures)of Sichuan Province during the research period? Second,what are the spatial distribution characteristics of the coupling coordination degree of urban and rural development in 21 cities(prefectures)of Sichuan Province during the research period? Third,what are the major obstacles to the coordinated development of urban and rural areas in 21 cities(prefectures)of Sichuan Province? In view of the above problems,first of all,based on the definition of related concepts,combing related theories and reviewing relevant literature at home and abroad,this paper systematically analyzes the coupling and coordination mechanism of urban and rural development from the perspective of "element structure function",which provides an important analytical framework and theoretical guidance for the subsequent research of this paper.Then,the paper constructs an index system to measure the development level of urban and rural sub-systems,uses entropy weight method to determine the weight,and then measures the development level of urban and rural sub-systems of 21 cities(prefectures)in Sichuan Province,with the help of coupling coordination degree model,measures the development level of urban and rural coordination of 21 cities(prefectures)in Sichuan Province from 2012 to 2017 and analyzes its changes.Finally,the paper analyzes the time sequence characteristics of the coupling coordination degree of urban and rural development in 21 cities(prefectures)of Sichuan Province in recent years.With the help of ArcGIS and geoda software,the paper uses the moran’i index and Moran scatter map and other exploratory spatial data analysis methods to analyze the overall and local spatial autocorrelation of the coordinated development level of urban and rural development in 21 cities(prefectures)of Sichuan Province in recent years,so as to find 21 cities(prefectures)of Sichuan Province The spatial agglomeration characteristics of urban and rural coordinated development.On the basis of the above research,the paper puts forward the policy suggestions of regional classification guidance to improve the coordinated development level of urban and rural areas in Sichuan Province.Through the above research,this paper mainly draws the following conclusions.Chengdu,Panzhihua,Deyang and Mianyang have become the "highlands" of the coordinated development of urban and rural areas in the province.Bazhong,Ganzi,Aba,Guangyuan,Suining,Nanchong,Liangshan and other cities(prefectures)are faced with the practical problems that the input of urban development factors is insufficient,resulting in the low level of urban development,which restricts the coordinated development of urban and rural areas in these areas The important factors of the level improvement;Aba,Ganzi,Neijiang,Meishan,Guang’an,Zigong,Yibin and other cities(prefectures)are faced with the reality that the rural function weakens and the rural development slows down,which has become an important factor restricting the level improvement of the coordinated development of urban and rural areas in these areas;the urban and rural function of the whole province shows a weakening trend,which leads to the weakening of the development power of urban and rural areas in the whole province and is not conducive to the coordination of urban and rural areas in the whole province Development: the spatial relevance of the coupling degree of urban and rural development in Sichuan Province is also gradually weakening.Only from 2012 to 2013,there is a significant spatial positive correlation between the coupling degree of urban and rural development in Sichuan Province,showing a more obvious spatial agglomeration feature.However,the global moran’i index shows a fluctuating downward trend,and the spatial agglomeration feature of the coupling degree of urban and rural development in Sichuan Province is becoming less significant The "highland" of rural coordinated development level is obviously insufficient to the radiation driving capacity of surrounding areas.According to the above main research conclusions,in view of the main problems faced by the coordinated development of urban and rural areas in Sichuan Province and the new requirements of urban and rural integration development,the following policy recommendations are put forward with full reference to the experience of coordinated development of urban and rural areas at home and abroad.We will strengthen the economic and social functions of urban and rural areas in terms of strengthening urban and rural infrastructure construction,enhancing the development vitality of private enterprises,and promoting the inclusive sharing of urban and rural basic public services,so as to promote the coordinated development of urban and rural areas in the province at a higher level;we will speed up efforts to make up for the shortcomings in urban and rural development in Bazhong,Ganzi,Aba,Guangyuan,Suining,Nanchong,Liangshan and other cities and prefectures,and strengthen urban development in these areas The input of factors will promote the coordinated development of urban and rural areas in these areas;speed up the improvement of rural development in Aba,Ganzi,Neijiang,Meishan,Guang’an,Zigong and Yibin,encourage the integration of three industries in these areas,enhance the rural economic function,and promote the coordinated development of urban and rural areas in these areas;give full play to the high-quality coordinated development of urban and rural areas in Chengdu The demonstration role of the exhibition is to enhance the radiation and driving role of small and medium-sized cities in rural development,establish regional rural development consortiums,strengthen regional cooperation and exchanges,enhance the spatial relevance of the coupling and coordination of urban and rural development in the province,and promote the inter regional interaction of urban and rural development. |
