China still faces relatively serious energy poverty, and technological innovation is considered effective at alleviating this issue. This paper empirically investigates the impact of regional technological innovation on energy poverty based on panel data from 30 provinces in China from 2001 to 2020. This paper explores the effect of industrial structure distortion in the process of technological innovation on energy poverty. This paper conducts asymmetry analysis and investigates the heterogeneous impact of technological innovation on energy poverty in different areas. The research conclusions are as follows: (1) Regional technological innovation can effectively alleviate energy poverty. (2) Industrial structure distortion moderates the impact of technological innovation on energy poverty, and it weakens the effect of technological innovation in alleviating energy poverty, although the moderating effect is not significant in coal-producing regions. (3) The effect of technological innovation on alleviating energy poverty is more obvious in regions where energy poverty is prominent. (4) The role of technological innovation in alleviating energy poverty shows spatial heterogeneity, and this alleviation effect is more obvious in the western and non-coal producing regions. We also propose several policy implications for alleviating energy poverty. • Regional technological innovation can effectively alleviate energy poverty. • Industrial structure distortion moderates the impact of technological innovation on energy poverty. • Industrial structure distortion hinders the ability of technological innovation to alleviate energy poverty. • Technological innovation is more effective in alleviating energy poverty in regions where energy poverty is severe. • Technological innovation is more effective at alleviating energy poverty in the west and non-coal-producing regions.

Whether renewable energy consumption is beneficial to reducing CO 2 emission intensity and carbon emissions in the context of the goal of "carbon peak and carbon neutrality" in China. To prove this conjecture, considering the spatial spillover effect of carbon dioxide, this paper adopts the spatial Dubin model for empirical analysis based on the panel data of China's 30 provinces over the period 2002–2019. This study explores the CO 2 intensity mitigation effect of China's renewable energy consumption and further investigates the mediation role of technological innovation, industrial structure upgrading and optimization, and energy efficiency in the nexus between renewable energy consumption and carbon intensity. The main findings present that: (1) China's carbon emission intensity is characterized by significant spatial correlation; (2) Renewable energy consumption can significantly reduce carbon intensity and per capita carbon emissions; (3) The mediation effect of renewable energy consumption in reducing carbon emission intensity is to promote technological innovation and industrial structure upgrading, as well as improve energy efficiency. Based on the conclusions, this paper offers several policy implications for governments to reduce CO 2 emission intensity. • The impact of renewable energy consumption on CO 2 emission intensity is explored. • Renewable energy consumption can reduce carbon emission intensity and per capita carbon emissions. • Renewable energy consumption reduces CO 2 intensity through the spatial mediation effect.

The importance of dealing with the relationship between foreign direct investment (FDI) and green innovation for sustainable development is being highlighted. However, since FDI can have both positive and negative effects on sustainable development, coupled with regional differences and different development conditions, there is uncertainty about the relationship between FDI and green innovation. Based on the panel data of 30 provinces in China from 2007 to 2018, this paper uses the two-tier stochastic frontier model to decompose the positive and negative effects of FDI on green innovation in different time periods and provinces, and considers the role of regional conditions that lead to regional differences in the green innovation effects of FDI, in order to better provide precise research findings for analyzing the relationship between FDI and green innovation in different provinces in China. First, empirical research shows that the inhibition effect of FDI on green innovation efficiency is smaller than the promotion effect, which makes the combined effect not obviously positive. The average inhibition effect of FDI on green innovation efficiency is 0.0041 and the average promoting effect is 0.0047, which makes the combined effect averaged 0.0006. Second, there are regional differences in the driving effect of FDI on green technology innovation. The western region's FDI has a greater drive effect on the efficiency of green innovation than the central and eastern regions. Third, the promoting effect character of FDI on green innovation efficiency is a "U" type with 70% percentile of the environmental regulation intensity as the inflection point. Due to the imperfection of China's economic structure at this stage, China's relatively developed regions have not yet established the market and industrial structure advantages to fully release the green innovation effect of FDI. Based on the research conclusions, to better promote green innovation efficiency, it is necessary to overcome the disadvantages of the green innovation process dominated by the central government, cultivate and develop green innovation markets, adopt incentive initiatives for foreign enterprises with green technology spillover effects, implement policies to address regional differences, and strengthen the interaction mechanism between FDI and green technology innovation in home countries. • Analyze the bilateral effects of FDI on green innovation efficiency. • FDI not only promotes but also restrains the efficiency of green innovation. • The inhibition effect of FDI is smaller than the promotion effect. • The combined effect of western regions is greater than eastern regions in China.
