The digital economy has significant economic structural transformation effects and income distribution effects. This article analyzed the impacts and mechanisms of digital economy development on the efficiency of dual-economic factor allocation and the urban–rural income gap from a theoretical perspective, empirically tested by using China’s provincial panel data from 2008 to 2017 and a bidirectional fixed effects model. It was found that the development of the digital economy has significantly improved the efficiency of factor allocation in the dual-economy, which has a significant improvement effect on the allocation efficiency of capital and labor. The development of the digital economy alleviates the problem of surplus labor factors and insufficient capital input in the agricultural sector by promoting nonagricultural employment and the flow of capital factors to the agricultural sector. The development of the digital economy can significantly reduce the urban–rural income gap by improving the efficiency of factor allocation in the dual-economy. The main contribution of this article is verifying that the flow of production factors triggered by the digital economy has a configuration efficiency improvement effect and further extending the economic structure effect of the digital economy to the field of distribution, examining the feasible path of optimizing the income distribution pattern of the digital economy.

This article investigated the “National Information City for Public Service” policy as the representative policy of China’s digital transformation of urban governance to empirically analyze its impact on urban environmental pollution using the DID method. The results indicated that: ① The “National Information City for Public Service” policy has significantly reduced the level of urban environmental pollution by 1.65–2.11% on average. After conducting the robustness test of the PSM-DID method and excluding the effect of exogenous interference of the smart city pilot policy in China, the evaluation showed no significant difference from the conclusion above. ② The mechanism test results showed that the “National Information City for Public Service” policy could reduce urban environmental pollution through the technological innovation effect, industrial structure upgrading effect, resource allocation optimization effect, and urban informatization level improvement effect. ③ The heterogeneity analysis of the city scale presented a positive relationship between the city scale and the level of environmental pollution improvement effect under the “National Information City for Public Service” framework. Meanwhile, the heterogeneity analysis of city characteristics showed that cities with better human capital qualities, stronger local government financial strength, and more advanced financial development levels would obtain greater benefit from the environmental improving effect of this policy. Notably, the environmental improving effect of digital transformation of urban governance would be further amplified in cities with the dual superposition of the Innovative City Pilot Policy and the policy of “National Information City for Public Service”. This paper contributed significant referential insights into promoting urban digital transformation and improving urban ecological environment.

This study focuses on the effects of China’s carbon peaking policy, investigating how to balance nonfossil energy consumption and coal consumption to achieve China’s carbon peaking policy goal. The research applies the recursive dynamic computable general equilibrium model to simulate the impact of China’s energy planning policies using five scenarios to analyze the carbon emissions and economic effects of China’s energy planning policy from the perspectives of energy use, carbon emissions, the macroeconomy, and institutional income. The simulation results indicate that to achieve the goal of carbon peaking by 2030, the annual installed capacity of nonfossil energy must reach 112.29 gigawatts, and average annual coal consumption in the China 15th Five-Year Plan and 16th Five-Year Plan should be reduced by 20 million and 40 million tons, respectively, which will result in the proportion of nonfossil energy in primary energy consumption reaching about 25%. Limiting coal consumption will slow economic growth, whereas increasing the installed capacity of nonfossil energy will stimulate economic growth. The combined policies will have a significant impact on reducing carbon emissions and achieving the carbon peaking goal and will also offset the adverse effects of such policies on the macroeconomy.

Even though digitization is widely recognized as one of the most imperative trends in achieving effective urban governance, digital infrastructure remains far from the global trend in many African countries. This paper proposes a novel, resilient data manipulation architecture model called the Birth Notification Verification Model (BNVM) using blockchain and smart contracts. The proposed solution was evaluated in a real-world use case scenario in Ghana. The model, which is based on the Ten Civil Registration and Vital Statistics (CRVS) Framework, focuses on the initial inputs for birth registration at the birth notification level. The approach presented in this study paves the way for the creation of decentralized, secure, transparent, and automated systems for civil registration. The application of a smart contract architecture that blends a centralized design with an on-chain and off-chain architecture is further supported by this, providing more evidence of its viability. It offers a safe verification framework for the Ghana Birth and Death Registry based on smart contract technology and can guarantee a birth notification as proof of birth certificate registration in accordance with international standards. The findings provide insight into the use of blockchain technology in public registry institutions. Furthermore, exploring its adoption and implementation in Sub-Saharan Africa contributes to the growing field of blockchain technology research and demonstrates how the concept will address long-standing issues with corruption and security in developing countries.
