5.1. Conclusions
- (1)
- In the past decade, the overall trajectory of China’s digital economy has shown an increasing tendency over time. All four sub-dimensions have demonstrated positive trends, although the issue of uneven development persists. Among them, the rapid growth of digital industrialization has shown significant advantages, while the level of digital environmental governance has not received strong development. China’s digital economy continues to grow, and its digitalization process is advancing in all aspects. According to predictions, Guangdong, Beijing, Jiangsu, Shandong, Zhejiang, and Shanghai will be ranked as the top six provinces in terms of digital economic development over the next five years. The Bohai Rim, Yangtze River Delta, and Pearl River Delta regions are significant areas of concentration with respect to the three primary economic circuits and have significant development potential, but other areas may also present new opportunities for growth and breakthroughs.
- (2)
- Regarding regional distribution, it is clear that there is substantial spatial variability across the various provinces’ degrees of development, with a gradient that gradually narrows as one moves from coastal to inland areas. The Bohai Rim, the Yangtze River Delta, and the Pearl River Delta, which mostly comprise Beijing, Shanghai, and Guangdong, are the three main economic circles that make up the digital economy. The “Twin Cities Economic Circle” in the southwest region, mainly consisting of Chengdu and Chongqing, has great development potential. At the same time, there is a significant “digital divide” and “Matthew effect”.
- (3)
- From our spatial correlation analysis, Moran’s I index calculation reveals that the index is strongly positive in all years, with a “convex” shape. Economically developed and mature provinces show spatial distribution characteristics that are characterized by agglomeration. The agglomeration phenomenon shows a gradually shifting trend from low-value high agglomeration to high-value relative dispersal, forming significant non-equilibrium. As time passes, the development of the spatial spillover effect among provinces has gradually become stronger. Additionally, our examination of hot- and coldspots reveals a more pronounced spatial clustering pattern that is mostly seen in the dispersion of hotspot areas as well as the stabilization of coldspot locations. The spatial agglomeration and spillover of the four sub-dimensions also exhibit different geographical characteristics.
- (4)
- We considered the external influencing factors and forecasted spatial distribution, with industrial structure, foreign openness, government support, and technological progress. Technological progress is a positive driving factor with an increasing impact. Technology-oriented spatial spillovers are evident, with high-value areas advancing from south to north. The industrial structure regression coefficient is highly positive and rising annually, showing a distribution pattern of north–south differences, and the optimization of industrial structure has, to some extent, narrowed the development gap among provinces. Government support plays an important role and there is spatial non-stationarity. As time progresses, the low-value area advances from east to north. The impact of FDI is relatively small and there is spatial non-stationarity. This was hindered in most regions in 2020 due to external environmental factors, but it is predicted to have an overall positive promoting effect for all provinces by 2025.
5.2. Policy Implications
- (1)
- To adapt to local conditions, the objective is to modify the industrial structure as effectively as possible. The optimization of industrial structure has somewhat mitigated the variation in the growth of the digital economy among provinces. By leveraging their respective strengths and advantages, different regions can promote the expansion of the digital sector in a focused manner. This may involve transforming traditional manufacturing into digital intelligent manufacturing and cultivating clusters of industries associated with the digital economy. The “Bohai Rim”, “Yangtze River Delta”, and “Pearl River Delta” serve as the focal areas of these three main economic circles, and the dispersion effect is crucial in spreading and promoting regional digital activities. Local features may serve as a basis for the western and northeastern areas. To accomplish greater adoption and improve the strength of a certain area of the digital economy, and to realize the goal of leading the surface, breakthrough development is necessary.
- (2)
- Relevant policies promote development. Development relies on government support and external cooperation. To effectively address uneven development, with the advancement of artificial intelligence technologies, relevant policies should be implemented to promote coordinated regional development, seize the new opportunities for international competition brought about by the new Industry 4.0 era, and actively participate in cross-border digital economy cooperation. At the same time, it requires strong digital technology as a guarantee. The government can promote innovation and development by advancing relevant policies and regulations, enhancing digital infrastructure development, supporting innovative digital technologies, and expanding digital business models. However, data, networks, and media are exchanged and shared in large quantities in the process, so it is also vital to protect digital privacy and data security.
- (3)
- Promoting the transformation of digital industries. Investment in innovation serves as a catalyst for scientific progress and technological innovation, playing a pivotal driving role. At the macro level, conventional industries’ digital transformation has emerged as a significant tool and a crucial connection in fostering rapid growth. At the micro level, digital transformation can aid traditional industries in enhancing production efficiency, optimizing management processes, improving product quality, and increasing innovation capabilities. This can enable them to better adapt to market demand and enhance competitiveness. The process of digital transformation takes time and will evolve gradually, requiring constant adaptation and adjustment by organizations and businesses in terms of technology, models, and formats. Therefore, companies in various industries and fields must face the important choice of “rebirth from the ashes” and continually enhance their awareness of the importance of digital transformation.
