Research On The Role Of Smart City Construction On Urban Green Development

Achieving the green development of cities is an urgent need to alleviate the current big city disease" intensifying,and it is also an important part of achieving sustainable and highquality development of the country.In order to realize a resource-saving and environmentfriendly development model,cities cannot do without the construction of smart cities.The proposal of smart city provides a new way to solve the problem of urban development.Not only does smart city itself contain the concept of green development,but the construction of various systems in smart city also affects the level of green development of the city in many ways.Therefore,it is of great significance to study the impact of smart city construction on the green development of cities,for the scientific planning of smart city construction,to realize the production and lifestyle of resource conservation and environmental protection,and to promote the coordination between the development of human society and the development of natural society.On the basis of defining the concepts of smart city and green development,this paper establishes a smart city evaluation index system and an urban green development index system,and conducts an all-round comprehensive evaluation of the smart city construction and urban green development level in the central and western regions,and taking the underdeveloped smart city agglomerations in the central and western regions as research samples,using the grey relational analysis method to empirically test the degree of correlation between the construction of smart cities and the level of urban green development,as well as the different correlation characteristics reflected in the four major urban agglomerations in the central and western regions.The research conclusions show that:(1)Smart city construction is a systematic project,including five systems:smart infrastructure,smart industry,smart citizens,smart location,and smart governance services.Each system has an impact on the level of urban green development from different perspectives,among which the smart location has a core impact;(2)The development of smart cities in the central and western regions is hierarchical,and the degree of smart coordination within the urban agglomeration is insufficient.Xi’an,Chengdu,Chongqing,Wuhan,and Zhengzhou play an important leading role as "smart leading cities".Other cities have relatively low levels of intelligence and have not yet formed a strong support for central cities;(3)The distribution of green development levels in the central and western cities is relatively concentrated,and most cities are still in the primary stage of green development,while the green development levels within urban agglomerations are relatively stratified,and the coordination degree of green development within urban agglomerations is low;(4)The relationship between the construction of smart cities in the central and western regions and the green development is as follows:From 2012 to 2020,the impact of smart governance services on urban green development is the strongest,followed by smart areas,while the impact of smart infrastructure,smart citizens,and smart industries on urban green development is weak.(5)The relationship between smart city construction and green development in the four major urban agglomerations in the central and western regions is as follows:From the perspective of the internal correlation of the urban agglomeration,among the Guanzhong Plain urban agglomeration,the Chengdu-Chongqing urban agglomeration,the Wuhan urban agglomeration and the Central Plains urban agglomeration,the of smart governance services and smart location on green development is most strongest.In comparison between urban agglomerations,the Guanzhong Plain urban agglomeration has comparative advantages in terms of smart infrastructure,smart citizens and smart industries for urban green development.The Central Plains urban agglomeration has comparative advantages of smart location,while the Chengdu-Chongqing urban agglomeration has comparative advantages in terms of smart governance services.Based on the empirical results of this paper,three countermeasures and suggestions are put forward,namely:overall planning and layout,giving full play to location advantages;improving development mechanism and improving developement quality;based on urban agglomerations,building smart cities.
