In the context of the global move into the digital economy (DEC) era and the accelerated development of the green industry, constructing a unified large market provides a powerful accelerating effect for the green transformation and upgrading of the manufacturing industry (GTUM) empowered by DEC. This study employs panel data combining China’s provincial level with the level of manufacturing subsectors from 2011 to 2020. It examines the impact of DEC and the construction of a unified large market on GTUM and its action mechanism at the theoretical and empirical levels by combining the traditional econometric models with geographic information systems, machine learning models, and other advanced technologies. Results indicate that DEC significantly enhances GTUM. Relative to the efficiency aspects of GTUM, the impact of DEC is more pronounced on energy consumption and environmental protection. Mechanism tests reveal that DEC primarily facilitates GTUM by reducing market segmentation effects, stimulating market potential effects, and matching market supply and demand effects. Heterogeneity analysis finds that in regions with higher levels of trade openness, technological innovation, and public environmental awareness, DEC more effectively promotes GTUM. Analyzing the temporal dynamics of this influence, the impact of DEC on GTUM aligns with Metcalfe’s Law, which posits a non-linear characteristic. Furthermore, the construction of a unified large market amplifies the effect of DEC empowering GTUM. This study offers a novel pathway for China to fully leverage DEC and the advantages of an ultra-large market to enhance the level of GTUM. It also provides valuable insights for the green development of industries globally.

3.1. Selection of Supplementary Inspection Points We have noticed that the density of patrol points can greatly affect the quality of drone inspections on highways, as (1) the highway management department does not recommend drones to fly directly over highways, but rather over both sides of the road to prevent drones from falling to the ground and posing risks to the operation of highways; (2) if the drone’s patrol points are too sparse, the drone’s straight-line flight between points will...

Abstract:Internet of Things (IoT) technology has permeated into all aspects of today’s society and is playing an increasingly important role. Identity authentication is crucial for IoT devices to access the network, because the open wireless transmission environment of the IoT may suffer from various forms of network attacks. The asymmetry in the comprehensive capabilities of gateways and terminals in the IoT poses significant challenges to reliability and security.

Abstract The early kinetic decoupling (eKD) effect is an inevitable ingredient in calculating the relic density of dark matter (DM) for various well-motivated scenarios. It appears naturally in forbidden dark matter annihilation, the main focus of this work, which contains fermionic DM and a light singlet scalar that connects the DM and standard model (SM) leptons.
