The Experience and Enlightenment of Asian Smart City Development—A Comparative Study of China and Japan

Abstract

With the urbanization level advancing in cities, increasingly significant urban ecological environment problems must be solved. The construction of a smart city with the overall development of information technology also regards environmental friendliness as the primary goal. The “smart” idea of urban environment innovation and governance has become a new model. In this paper, we first expound on the development process of low-carbon cities, eco-cities, and smart cities in Japan and China. Then, we analyze the coordinated development of intelligent environmental protection measures in government policies, transportation, energy utilization, resource recovery, and community management. Finally, we compare Japan and China’s smart city development characteristics. We discuss the improvement measures for energy utilization, urban transportation, and urban operation, including developing renewable energy systems, efficient energy use, and citizen participation policy. These experiences can provide feasible measures for constructing Asian smart cities and have great significance for the city’s sustainable applications and practice.

Smart city and earnings management: Evidence from China

“…Furthermore, the study reveals that in industries closely associated with smart city development, the impact of smart city construction on corporate earnings management is more pronounced. Specifically, smart city pilots stimulate significant growth in regional digital projects, resulting in substantial enhancements in the local information environment [ 10 , 16 ]. In addition, the optimization and transformation of urban environments through smart city construction enhances the attractiveness of cities to migrants, thereby increasing the local housing demand [ 85 ].…”

“…While sharing commonalities in utilizing technology to enhance public services and economic growth, Chinese cities have adopted approaches to smart city construction that differ from those in developed countries [ 16 ]. Chinese smart cities exhibit a top-down construction approach [ 17 ].…”

“…In China, smart city construction emphasizes comprehensive data development in government affairs, management, and services, with the objective of facilitating data co-creation and sharing, reducing information asymmetry in the market [10,16]. Such measures are likely to mitigate earnings management and enhance the quality of financial information [44].…”

Research on the Influence Path of Digital Technology to Promote Green Transformation under Public Green Concern

“…In addition, digital technology infrastructure is not only critical for sustainable production and consumption, but also the use of cleaner production technologies and climate mitigation (Muhammad et al, 2021). Digital technology infrastructure is conducive to intelligent cities and to the enabling of green technology innovation in areas such as comprehensive energy utilization, urban tra c management, and pollutant emission reduction and treatment through the establishment of 'Smart Cities' (Su et al, 2022). At the same time, increasing investment in digital technology infrastructure itself has a signi cant effect on reducing carbon emissions.…”

Formation of multiple aerial LED signs in multiple lanes formed with AIRR by use of two beam splitters

“…The second is the evolution of technology. Self-driving technology is being developed [4], and cities are becoming "smart city" [5,6]. In addition, "flying cars" are currently being researched [7,8], and will be put to practical use in the near future.…”
