| " Opinions of the Central Committee of the Communist Party of China and the State Council on the establishment of a more effective new mechanism for regional coordinated development " The Central Committee of the Communist Party of China and the State Council ’s guidance on promoting the development of the western region in the new era to form a new pattern ’ clearly states that it is necessary to ’ strengthen cooperation in inter-provincial border areas ’,’ establish and improve the docking mechanism for the planning of upstream and downstream adjacent provinces and cities ’,’ support the old revolutionary areas such as Shaanxi-Gansu-Ningxia,Sichuan-Shaanxi,Zuoyoujiang and other old revolutionary areas and Sichuan-Chongqing,Sichuan-Yunnan-Guizhou,Chongqing-Guizhou and other inter-provincial(autonomous regions,municipalities directly under the central government).Establish and improve a coordinated and open development mechanism.’ Under this background,the adjacent area of Sichuan,Yunnan and Guizhou is a typical inter-provincial adjacent area in southwest China,one of the main positions for the planning and docking of adjacent provinces and cities in the upper and lower reaches of the Yangtze River Basin,a key short board for the new pattern of the western development.Therefore,promoting the coordinated development of the adjacent areas of Sichuan,Yunnan and Guizhou not only determines the long-term development of the region itself,but also affects the coordinated development pattern of the Yangtze River Basin,and is more related to the formation of a new pattern of China ’s western development strategy.Firstly,this thesis combs and explains the relevant theoretical basis and research results at home and abroad.Secondly,after clarifying the concept of adjacent areas,this thesis defines the scope of adjacent areas in Sichuan,Yunnan and Guizhou as Luzhou City,Zunyi City,Bijie City and Zhaotong City based on the principle of determining the scope of adjacent areas.Thirdly,this thesis measures the coupling degree,comprehensive benefit index score,coupling coordination degree and obstacle degree model of the ecological-economic-social composite system in the adjacent areas of Sichuan,Yunnan and Guizhou from 2009 to 2020.Finally,based on the above research,this thesis puts forward corresponding countermeasures and suggestions.(1)From the coupling level of the ecological-economic-social complex system in the adjacent areas of Sichuan-Yunnan-Guizhou : First,the level of coupling and coupling coordination in the adjacent areas of Sichuan,Yunnan and Guizhou showed an increasing trend during the study period.Secondly,the changes of coupling degree in the adjacent areas of Sichuan,Yunnan and Guizhou during the study period can be roughly divided into three categories,namely,the counties that have changed from the low-level coupling stage to the antagonistic stage,the counties that have been in the antagonistic stage,and the counties that have changed from the antagonistic stage to the running-in stage.Among them,the districts and counties that have been in the antagonistic stage account for the largest proportion,the districts and counties that have changed from the low-level coupling stage to the antagonistic stage account for the smallest proportion,and the districts and counties that have changed from the antagonistic stage to the running-in stage account for the middle proportion.Thirdly,the changes of the coupling coordination degree in the adjacent areas of Sichuan,Yunnan and Guizhou during the study period can be roughly divided into three categories,namely,the districts and counties that have changed from the imbalance recession stage to the over-coordination stage,the districts and counties that have been in the imbalance recession stage,and the districts and counties that have changed from the imbalance recession stage to the coordinated development stage.Among them,the proportion of districts and counties that have been in the stage of dysfunctional recession is the largest,the proportion of districts and counties that have changed from the stage of dysfunctional recession to the stage of coordinated development is the smallest,and the proportion of districts and counties that have changed from the stage of dysfunctional recession to the stage of excessive reconciliation is in the middle.Fourthly,the districts and counties with the highest comprehensive benefit index score of the ecological-economic-social composite system in the adjacent areas of Sichuan,Yunnan and Guizhou are often the central urban areas of the prefecture-level cities.(2)The change of the obstacle degree of the criterion layer in the adjacent areas of Sichuan,Yunnan and Guizhou has the following characteristics : First,in the early stage of the study,the order of subsystem obstacle degree(from high to low)of the ecological-economic-social composite system in the adjacent areas of Sichuan,Yunnan and Guizhou is economic subsystem,social subsystem and ecological subsystem.With the change of time,the obstacle degree of ecological subsystem in the central urban area of each prefecture-level city began to gradually rise,and the obstacle degree of ecological subsystem in the non-central urban area began to gradually decline.The obstacle degree of economic subsystem in Luzhou City began to gradually decline,and the obstacle degree of economic subsystem in Zunyi City,Bijie City and Zhaotong City began to gradually rise.The obstacle degree of social subsystems in the districts and counties adjacent to Sichuan,Yunnan and Guizhou has generally declined.Secondly,the more urgent task in the adjacent areas of Sichuan,Yunnan and Guizhou is to improve the level of local public services,boost economic power and expand economic scale.The secondary task is to optimize the economic structure,improve people ’s living standards,optimize the state of the ecosystem,reduce ecological pressure,and reduce the size of the government.Third,for the three subsystems,the top three obstacle factors of the ecological subsystem are agricultural machinery power input per unit of grain output(A31),urbanization rate(A22),and forest coverage rate(A21).The top three obstacle factors of the economic subsystem are the total social fixed asset investment(B32),total retail sales of social consumer goods(B33),and per capita regional GDP(B12).The top three obstacle factors of the social subsystem change more frequently.The top three obstacle factors during the study period were the proportion of broadband access users(C22),the ratio of compulsory education teachers to students(C23),the balance of savings deposits for urban and rural residents per capita(C13),the per capita disposable income of rural residents(C12),and the number of beds in hospitals and health centers per capita(C21).According to the existing theoretical analysis and empirical results,the following suggestions are put forward :(1)Speed up the construction of agricultural modernization level and reduce the pressure of agricultural ecosystem.(2)Accelerate the concentration of population to central towns and reduce the disorderly development of natural resources by rural residents.(3)Continue to vigorously implement the forest chief system,river chief system and lake chief system to enhance the green conservation capacity of forests.(4)Accelerate the construction of green cities and promote the green development of urban ecosystems.(5)to strengthen the transfer payment policy in neighboring areas to enhance the consumption vitality of residents.(6)Strengthen the optimization of business environment and attract high-quality enterprise project investment.(7)Strengthening digital infrastructure and accelerating the development of a digital economy in neighboring regions.(8)Expand the supply of high-quality inclusive resources and create happy urban and rural areas in the adjacent areas of Sichuan,Yunnan and Guizhou. |
