Evaluation on Construction Level of Smart City: An Empirical Study from Twenty Chinese Cities

Currently, the construction of smart cities (SCs) has been booming all over the world and it also acts as a useful tool for the Chinese government to promote the sustainable development of cities. Identifying the aspects of SCs and systematically evaluating the level of smart city construction are significant for urban management and healthy development. Based on the bibliometrics and Chinese experience with smart city construction, this paper firstly proposes dividing the smart city system into four subsystems, that is, smart infrastructure, smart economy, smart governance and smart participation and to establish their corresponding indicator systems. Information entropy method and grey correlation analysis are then adopted to determine the weight of each indicator and evaluate the city smartness level respectively. After that, 20 major cities in China are taken as cases for evaluation. The evaluation is performed on the grey correlation degree of these cities and their variations between 2012 and 2016. Through the further comparison of regional distribution and clustering analysis of these cities, the paper points out the general characteristics and level differences of smart city construction in China. Finally, some policy implications are proposed to improve the smartness level for Chinese cities.

More countries and regions are joining the bandwagon of smart city construction, which is an important strategy and innovative urban governance concept to solve the problem of rapid urbanization. This paper examines whether smart city innovation is able to ameliorate the traffic congestion faced by a large number of cities. Using panel data for 187 prefecture-level cities in China from 2008 to 2017, this paper tests the effect of implementation of a smart city on urban traffic congestion with the difference-in-difference method. The results show that, firstly, the construction of smart cities have significantly reduced the degree of urban traffic congestion and improved the quality and capacity of public transport. Secondly, information technology and urban innovation are the main mechanisms for smart city implementation to improve urban traffic problems. Thirdly, the improvement effect of smart city implementation on traffic management shows an increasing marginal effect over time. By overcoming the estimation bias in previous studies, this study accurately analyzes the positive role and dynamic effect of smart city construction on traffic improvement. It augments the literature of program evaluation and assessment of smart city implementation. By examining how to improve traffic congestion, it offers some insights that could inspire governments to build smarter cities with better traffic.

The City

Urban color is becoming more and more important in the construction of smart cities. This research mainly discusses the influencing factors of AHP-based 3D regional color smart city construction. From the perspective of city managers, the factors selected in the article that affect the choice of urban color planning are economic development, urban culture, designer’s ideas, customs, and natural environment. We use GIS to comprehensively collect basic geographic information data of the city. We use CityEngine and GIS data to quickly create virtual cities. When constructing the AHP model, once the weight value of each factor in the color-influencing factors of the entire smart city is obtained, the total ranking of the levels needs to be checked once. After that, the study uses the MATLAB program platform to realize the parametric design of the main color of the city, including the control of the changes in the spatial structure of the main color of the city, followed by the control of the transition and coordination mode between the key elements of the city color. Explorer provides comprehensive and rich 3D digital city roaming browsing, query positioning, analysis, and other functions; supports the loading of multiple data sets from the Internet and local; and can dynamically load massive 3D city simulation models above and below ground. Finally, the design of the urban architectural color or improvement plan is further carried out, and the urban color main color design plan is finally implemented in the implementation of the urban architectural color, which effectively realizes the quantitative control of the urban color. When evaluating smart city color resources, the color weight value of public facilities is 0.147, which accounts for 14.7% of the total weight value. This research helps to enhance the regional and local cultural characteristics.

This article describes how being pushed and pulled by a variety of external and internal factors, the Chinese government had begun to adopt and implement its smart city initiatives. Despite the strong financial and institutional supports from the central government, the performances of smart city initiatives significantly vary across pilot sites. Considering smart city initiatives as government innovation and drawing on the government innovation diffusion theories, an explanatory model has been developed to examine their variance and test it with a cross-sectional dataset using multiple regression methods. It was found that although environmental pollution was a key driver for the development of smart city in China, such environmental pollution like air pollution in particular had a curvilinear relationship (bell-shaped) with smart city development. In addition, smart cities initiatives in China were driven not only by technical rationalities but also political rationalities. Political supports from local ruling party sectaries made a difference.

Smart city evaluation is a critical component in smart city construction and plays an important role in guiding and promoting smart development of cities. Currently, existing research and applications of smart city evaluation are still in the exploration stage. They mainly focus on evaluation of one single aspect, use indicators with distinct regional characteristics and poor extensibility, and cannot be well-integrated with common and shareable smart city frameworks; these limitations have led to biased evaluation results. Based on a common and shareable smart city framework, this paper proposes a well-integrated, universal, strongly practical, and highly extensible evaluation system. Then, using the above-mentioned evaluation system, 17 smart cities in China are assessed. This application demonstrates that the evaluation system plays an important guiding role for better understanding the overall smart city platform construction situation in China, performing horizontal comparisons and establishing benchmarks among smart cities. Comparative analyses of indicators demonstrate that future smart city construction in China should pay more attention to novel innovations, the construction of dynamic information resources and spatiotemporal big data.

Positive Effect

The construction of smart cities has promoted the process of urbanization and sustainable urban sprawl, which may accelerate regional coordination by enhancing the spatial correlation among the cities. Firstly, this paper built the mechanism for the impact of urban sprawl and smart city construction on regional coordination and adopted the corrected night light data as the index of economic measurement, using the dynamic fixed effect spatial Dubin model to test theoretical mechanism. It is found that urban sprawl has strongly promoted the regional coordination, which is especially obvious among the neighboring cities. However, the construction of smart cities is not conducive to regional coordination, only when interacting with urban sprawl. The results of robustness check and endogenous treatment are consistent with the baseline regression. Further research shows that urban sprawl restricts the positive effect of industrial agglomeration but could promote economic growth and regional coordination through smart city construction. The policy enlightenment lies in that smart city construction should be promoted, so as to improve economic growth, and smart city network and urban sprawl should be synchronously promoted to accelerate regional coordination.

Consider that 26.3 million people live in Shanghai and 20 million live in Beijing as of 2019. Now consider that these 46.3 million people live within an area of approximately 23,000 km². By comparison, Canada’s population in 2019 was 37.6 million and the area of Canada is approximately 10 million km². China is on the leading edge of smart-city projects because population density gives it little choice. China must take bold steps in terms of both technology and regulation to cope with the demands for social management, which these megacities create. Accordingly, about half of the Smart City Projects globally are in China. Many smart cities pilot projects are underway across China addressing many infrastructures and other organizational concerns. One such organizational concern is coping with the solid waste generated in cities. China produces more than 300 million tons of solid waste per year, and much of it comes from its cities. This research project explores China's food and beverage delivery online platforms and the waste they cause. In 2019, this industry has developed rapidly, generating economic activity valued at ¥ 653.6 billion that year ($CAD 121 billion). Out of a total population of 1.4 billion, 460 million people are currently consumers of these online platforms. Most of these consumers live in China’s megacities. This consumption is not projected to decrease post-pandemic. The problem is that solid waste from this industry in 2019 weighed approximately 2.7 million tons. This paper analyzes reasons why the online food take-out industry has caused a plastic waste surge from the perspective of China's environmental legislation, law enforcement efficiency, and recycling subsidies. At the same time, through the case study of the German Packaging Law, this paper suggested on the management and recycling of Chinese take-out packaging were put forward. The Chinese government has issued national standards for the design and construction of smart cities. This paper explores how to use legal governance and supervision in smart city design and operation to assist in implementing environmental regulations to control the take-out waste. The take-out waste problem does not only exist in China. Almost all major cities in the world are facing this problem. China's experiences may provide a new path for the city's solid waste disposal and other environmental issues and lead the cities to explore more environmental protection possibilities.
