As China enters an advanced stage of new urbanization, green and smart urban development emerges as a key strategy characterized by innovation-driven and environmentally sustainable development. As the world’s largest developing nation and leading energy consumer, China has set ambitious goals to peak carbon emissions by 2030 and achieve carbon neutrality by 2060. These targets reflect China’s commitment to sustainable development and its active role in global climate governance, aiming to build a shared future for humanity.

China’s position as a major smart city developer makes it a crucial testing ground for observing smart cities and urbanization trends. Unique characteristics such as its urban-rural dual structure, concentrated urbanization, and rapid growth distinguish China’s approach to smart cities from that of other regions. These factors contribute to a distinctive model of urban development, offering valuable insights for global smart city initiatives.

The Essence of Smart Cities

Smart city development has emerged as an innovation-driven strategy aimed at achieving green urbanization. According to the European Commission, a smart city leverages digital technologies to create smarter urban transport networks, upgraded water supply and waste disposal systems, and more efficient methods for lighting and heating buildings. A central objective of smart city initiatives, particularly in relation to environmental concerns, is to foster green development. “Smart” in the context of urban development refers to a new mode characterized by intelligence, digitalization, and informatization.

The core of smart cities involves leveraging cutting-edge technologies such as big data, the Internet of Things (IoT), and cloud computing to foster digital and intelligent urban development. This approach aims to enhance the efficiency of city operations and address urban issues effectively. Smart cities are characterized by six dimensions: smart economy, smart people, smart governance, smart mobility, smart environment, and smart living. The scientists further interpreted smart cities as a strategy-oriented evolutionary process driven by the interactions between technology, institutions, and people.

The Role of Smart Cities in Promoting Green Development

The question of how smart cities contribute to green development is often explored through the lens of environmental performance. Researchers and scientists often emphasize in their review that smart cities can enhance environmental quality by facilitating the rapid adoption of renewable energy technologies. Additionally, smart cities can drive innovation and increase investment in research and development, which ultimately benefits the environment.

Recently, China Development Bank Capital, in collaboration with Energy Innovation and Energy Foundation China, introduced a comprehensive set of 12 guidelines known as the Green & Smart Urban Development Guidelines. Refer to Figure 1 for a detailed understanding of these guidelines. Launched at the Wuhan Low Carbon Development Forum in November, these guidelines encapsulate key insights from global experiences in urban development tailored to China’s specific environmental, economic, and social contexts.

Green and Smart Urban Development in China

In the midst of rapid urbanization, China is witnessing the rise of green and smart urban development. Various individuals and initiatives are passionately advancing this journey, striving to balance urban growth with environmental sustainability.

The origins of the notion of a smart city may be found in IBM’s “Smarter Planet” idea, which was unveiled at the Council on Foreign Relations in New York in November 2008. IBM proposed leveraging Internet Information Technology across industries to achieve refined and dynamic management of production and daily life, thereby creating a globally intelligent society. The same year, IBM launched the “Smart City Breakthrough in China” strategy, signing co-development agreements with more than ten provinces and cities in China. China’s 14th Five-Year Plan prioritizes technological self-reliance, shifting towards a greener economy. This new urbanization strategy aims for a more equitable distribution of public goods and heightened investment in environmental technologies, laying the foundation for sustainable growth.

In 2023, the China International Fair for Trade in Services (CIFTIS) published the “Global New Smart City (SMILE Index)”, which listed Beijing, Guangzhou, and Hong Kong as three of the world’s top ten smart cities. This ranking underscores China’s significant advancements and leadership in the smart city domain.

Trends in Chinese Smart City Development

The development of smart cities in China is predominantly driven by a top-down approach that is led by substantial government investment. This strategy aligns with the country’s regional development patterns, with most smart city projects concentrated in the economically advanced eastern seaboard. In 2018, Chinese consulting firms estimated the smart city solutions market at RMB 7.9 trillion ($1.1 trillion) and projected a 33% compound annual growth rate from 2018 to 2022. However, the reliability of these estimates varies, reflecting the complexity and dynamic nature of the market.

Chinese municipal authorities responsible for smart city initiatives typically prioritize areas such as transportation, public services, public safety, education, healthcare, and environmental protection. These focus areas reflect a holistic approach to urban development, aiming to enhance the quality of life for residents while promoting sustainable and efficient city management.

Challenges in Green and Smart Urban Development in China

Despite numerous successful deployments of smart city solutions in China, several challenges remain. One significant issue is the long-term sustainability of these programs. It is critical to ensure that smart city projects can maintain their operations and impact over time. Another challenge is the lack of robust information-sharing mechanisms between different governing authorities. Effective communication and data sharing are essential for the integrated functioning of smart city systems. Additionally, there is a notable deficiency of inaccurate information regarding the actual progress and funding of smart city development. This lack of transparency can hinder the broader adoption and implementation of smart city initiatives across the country.

Beyond Technological Advancements

Technological progress, while essential, is not the sole requirement for developing a smart city. A smart city should embody a holistic vision of improved urban living, integrating technology with “people-oriented” development. Therefore, examining smart city development from a humanistic perspective is crucial, particularly amidst the current wave of technological advancements. This approach can contribute to building a better urban society in China.

Smart city construction represents a forward-thinking approach to urban development in China. By harnessing the power of big data, IoT, and cloud computing, smart cities aim to improve operational efficiency, promote sustainability, and enhance the quality of life for residents. While challenges remain, the potential benefits make smart city construction a promising solution for addressing the urban diseases that accompany rapid development. As China continues to advance its urbanization efforts, the smart city model offers a blueprint for sustainable and intelligent urban growth.

In conclusion, the potential of smart cities to enhance urban living depends not only on the tangible impacts of advanced information technology on human life and the spatial environment but also on a broader social transformation in consciousness and philosophy. This dual focus on technological and social dimensions will ultimately enable the realization of a smarter urban society in China.
