Summary: With the introduction of the digital age and urbanization in China, the digital economy (DE) has become an important factor in driving city sustainability (SUS). The impact of DE on SUS is influenced by the level of human capital (HC) accumulation and development. This study finds that DE has a significant positive effect on SUS, with a single threshold of HC. In areas with low HC levels, DE inhibits SUS, while in areas with high HC levels, DE particularly promotes SUS. The role of DE on SUS varies across different regions.

Summary: The relationship between urbanization rate and death incidence in inland provinces of China shows a non-linear single threshold effect, with the negative impact of urbanization on death rate decreasing when per capita GDP exceeds a threshold. This effect is significant in the northern provinces and not present in the southern ones.

Summary: This study empirically examines the impact of the digital economy on urban tourism development in China. The results show that the digital economy has a positive and nonlinear effect on urban tourism development, with a stronger impact observed in the mid-western region, non-tourist cities, key urban agglomerations, and low-level cities. Furthermore, the impact of the digital economy can spill over to neighboring cities through spatial effects, particularly relying on inclusive digital finance.

Summary: This study incorporates the environmental Kuznets model with the ecological environment index (ENV) and the digital economy index (DIG) to examine the effects of income, scale, structure, technology, and government expenditures on the ecological environment in China. The panel entropy value method is used to calculate the ENV and DIG, and a threshold effect test reveals a positive U-shaped relationship between the digital economy and the ecological environment. The results indicate that the digital economy significantly contributes to the improvement of China's ecological environment, and policymakers should promote its development while optimizing the regional industrial structure and increasing technological input support.

Summary: This paper examines the impact of the digital economy on innovation and analyzes it from various aspects such as elements, tools, subjects, and environment of innovation. The study constructs a development level index system for the digital economy and analyzes the temporal and spatial development in China. Additionally, the nonlinear impact of the digital economy on innovation, known as the threshold effect, is also studied. The research reveals that China's digital economy is rapidly developing, but there is a spatial imbalance and significant differences across different dimensions. Moreover, the impact of the digital economy on innovation exhibits both double threshold effects and single threshold effects.

Summary: Using panel data from 274 cities between 2011 and 2019, this article examines the impact of the digital economy on low-carbon transformation and the regulatory effect of public attention on urban low-carbon transformation using a panel threshold model. The findings reveal regional differences in the digital economy, urban low-carbon transformation levels, and public attention, with a decreasing trend from east to west. The study also highlights a U-shaped relationship between digital economy development and urban low-carbon transformation levels.

Summary: This study examines the impact of carbon capture, utilization, and storage (CCUS) technology on carbon emission efficiency and how that impact changes with the inclusion of the digital economy. Using panel fixed effect, moderating effect, and panel threshold regression models, data from China's 30 provinces between 2011 and 2019 is analyzed. The results show that improving CCUS technology significantly enhances carbon emission efficiency, and this enhancement is positively moderated by the digital economy. The relationship between CCUS technology and carbon emission efficiency is nonlinear, with significant double-threshold effects, and is influenced by the level of digital economy.

Summary: The sustainability of economic growth is a major objective for the global economy, and innovation has emerged as a key factor for efficient energy market and sustainable development. This study explores the impact of innovation on CO2 emissions and finds that it has a significantly negative effect on per capita CO2 emissions. In the early stages of renewable energy use, innovation is directed more towards clean energy, which contributes to the reduction of CO2 emissions.

Summary: The digital economy has a significant effect on reducing carbon emissions, especially in northern Ganzhou and regions with high carbon emissions. The digital economy can promote carbon emission reduction by strengthening the control of foreign investment introduction. The findings of this study provide a feasible path and policy reference for the digital economy in Jiangxi Province to contribute to carbon emission reduction goals.

Summary: Based on panel data from 31 provinces in China between 2011 and 2020, this study empirically examines the impact of the digital economy on urban resilience using various models. The findings indicate that the development of the digital economy has a positive effect on enhancing urban resilience. The effect varies across regions and shows a double-threshold characteristic due to different levels of digital financial inclusion. The study also highlights the positive spillover effect of the digital economy on the surrounding areas' urban resilience.
