In the context of China’s rapid economic development, corporate pollutant emissions are increasing, underscoring the imperative for further enhancement of corporate environmental performance. Given the significance of high-tech enterprises in the environmental domain, this study examines the impact of investor attention on the corporate environmental performance of Chinese high-tech enterprises. This study utilized data from 463 high-tech enterprises in mainland China from 2011 to 2022 and employed the dynamic panel generalized method of moments (GMM) technique. The findings indicate that investor attention has a negative impact on the corporate environmental performance of high-tech enterprises. This research also finds that both media attention and coverage sentiment mitigate the negative relationship between investor attention and environmental performance of high-tech firms. Heterogeneity analysis reveals that in the sample of IT service industry, heightened media attention exacerbates the negative impact of investor attention on corporate environmental performance, and media coverage sentiment exhibits no significant moderating effect. Within samples of non-polluting and state-owned enterprises, increased media coverage sentiment amplifies the negative impact of investor attention on corporate environmental performance. This paper suggests that policymakers should foster a media environment that supports accurate and thorough environmental reporting while businesses should proactively engage with media to align investor perceptions with sustainable environmental practices.

As a major emerging economy, China government debt burden on local governments remains substantial, so enhance fiscal self-sufficiency and debt sustainability is so important. Utilizing panel data spanning from 2004 to 2020 across 29 provincial-level governments in China, this study employs the SYS-GMM approach to empirically validate the significant negative impact of digital infrastructure development on governments’ fiscal self-sufficiency rates. Furthermore, the research shows the significant positive mediating role of technological expenditure efficiency between digital infrastructure and fiscal self-sufficiency, implying that digital infrastructure can enhance fiscal self-sufficiency by augmenting technological innovation efficiency. Under the moderating effect mechanism, fiscal decentralization positively moderates the relationship between digital infrastructure and fiscal self-sufficiency. Heterogeneity analysis reveals that the impact of digital infrastructure on fiscal self-sufficiency is more pronounced in high-density regions. At the same time, its effect is less significant in low-density areas, indicating regional disparities in China’s digital infrastructure development. The contribution of this study is grounded in fiscal decentralization theory, policy recommendations advocate granting local governments greater autonomy over tax categories and broadening their fiscal revenue. Concurrent efforts should be directed towards deepening reforms in the fiscal and taxation systems, as well as budget management mechanisms.

The use of digital technology by banks and other financial institutions to facilitate financial inclusion is referred to as digital financial inclusion. This fusion of digital finance and traditional banking methods has the potential to impact banks’ operational effectiveness. This study uses the panel effects model to examine the link between digital financial inclusion and bank performance in 30 Chinese provinces from 2012 to 2021. This research uses kernel density estimation to examine the spatial-temporal growth patterns of both variables. The mediator variable in examining how digital financial inclusion affects bank performance is risk-taking. Finally, the paper analyses the regional heterogeneity of the impact. It presents the following conclusions: (1) In China, digital financial inclusion and bank performance have constantly increased, with noticeable regional variances in their development levels. This regional inequality has widened gradually since 2018, yet it has not resulted in polarization. (2) The significant positive correlation between digital inclusive finance and banking performance indicates that banking performance tends to increase with the enhancement of digital inclusive finance. (3) Digital financial inclusion impacts bank performance, with risk-taking as a moderator. The spread of digital financial inclusion services enhances banks’ willingness to take risks, enhancing overall efficiency. (4) Digital financial inclusion boosts bank performance in the Northwest, South, North, and East regions while lightly inhibiting it in the Central region. Based on the findings, this study makes bank and government suggestions.
