The role of digital financial inclusion in China on urban-rural disparities in healthcare expenditures.

Introduction: The digital financial inclusion (DFI) provides opportunities to improve the relative capacity to pay for healthcare services by rural residents who are usually underserved by traditional finance in China. This paper provides empirical evidence on how the development of DFI affects the healthcare expenditure disparities between urban and rural residents. Methods: We employed the fixed effects model and instrumental variable method to estimate the impact of DFI on the Theil index of urban-rural disparities in healthcare expenditures, using panel data from 31 provinces (2011 ~ 2020) in China. We further adopted a moderating effect model to test whether the intensity of the impact would vary depending on the level of local government health expenditures. Results: The results suggest a negative association between the development level of DFI and the urban-rural healthcare expenditure disparities in China. For every 1% increase in the DFI index, the Theil index of urban-rural disparities in healthcare expenditures would fall by 0.0013. After changing the measurement method for the dependent variable and adjusting the sample, the results remain robust. Moreover, the result of the moderating effect model indicates that, a high level of government health expenditures is conducive to the impact of DFI. Discussion: Our research reveals that DFI plays an important role in bridging the urban-rural gap in healthcare expenditures. This finding provides new information for addressing the issue of urban-rural healthcare inequality in China. Chinese government needs to accelerate the construction of digital infrastructure and increase the penetration rate of digital tools in rural areas to promote the beneficial effects of DFI. Additionally, it is also necessary for local government to address the unbalanced allocation of medical resources between urban and rural areas, especially the shortage of rural human resources.

[Cloning and functional analysis of AcFMO from onion during alliine biosynthesis].

Flavin-containing monooxygenase (FMO) is the key enzyme in the biosynthesis pathway of CSOs with sulfur oxidation. In order to explore the molecular regulatory mechanism of FMO in the synthesis of onion CSOs, based on transcriptome database and phylogenetic analysis, one AcFMO gene that may be involved in alliin synthesis was obtained, the AcFMO had a cDNA of 1 374 bp and encoded 457 amino acids, which was evolutionarily closest to the AsFMO of garlic. Real-time fluorescence quantitative polymerase chain reaction (qRT-PCR) indicated that AcFMO was the highest in the flowers and the lowest in the leaf sheaths. The results of subcellular localization showed that the AcFMO gene product was widely distributed throughout the cell A yeast expression vector was constructed, and the AcFMO gene was ecotopically overexpressed in yeast to further study the enzyme function in vitro and could catalyze the synthesis of alliin by S-allyl-l-cysteine. In summary, the cloning and functional identification of AcFMO have important reference value for understanding the biosynthesis of CSOs in onions.

Environmental decentralization and carbon emissions: evidence from China.

A robust environmental management system holds great significance for the Chinese government in effectively managing the country's carbon emissions. This study delves into the spatial impact of environmental decentralization on the carbon emissions of 30 Chinese provinces spanning from 2000 to 2019. First, we found that the increase in environmental decentralization promotes carbon emissions, and this effect is primarily driven by the delegation of environmental monitoring authority and environmental supervision authority. Second, we analyzed the heterogeneity of the carbon emission effects of environmental decentralization across different regions and observed that the impact of environmental decentralization is more significant in the western region compared to the central and eastern regions. Furthermore, this study investigates how the industrial structure, government competition, and environmental regulation exert an influence on the carbon emission effects of environmental decentralization. This article presents empirical evidence from the perspective of environmental management systems that underscores the rapid escalation of carbon emissions. Additionally, it contributes to an enhanced comprehension of the economic ramifications linked to the process of environmental decentralization. At the same time, the conclusions of this article have significant practical implications for the rational design of levels of environmental decentralization, thereby accelerating the achievement of carbon neutrality.
