Catalytic pyrolysis of biomass has the potential to produce bio-oil , which is rich in aromatic hydrocarbons and can be used as transportation fuel. In this paper, microcrystalline cellulose were pyrolysis with HZSM-5(Si/Al=25), HZSM-5(Si/Al=50), HZSM-5(Si/Al=100), HY, Hβin a CDS5200 pyroprobe at temperature ranging from 450-650̊C. GC-MS is used to analyze the liquid product in the catalytic pyrolysis. Except the catalysts and pyrolysis temperature, this work also evaluated the influences of heating rate, catalyst-to-biomass ratios on the production yield of aromatic hydrocarbons and product distribution. HZSM-5(Si/Al=50) has the highest yield among the five catalysts. Catalytic pyrolysis at 500̊C、20K/ms heating rate and 5:1catalyst to biomass ratio is most suitable to produce aromatic hydrocarbons. Benzene, toluene, xylene and naphthalene are the main aromatic hydrocarbon products in catalytic pyrolysis of microcrystalline cellulose. [ABSTRACT FROM AUTHOR]

• Carbon emissions trading inhibits green technology innovation in the short run. • Carbon emissions trading will reduce the carbon emissions and carbon intensity greatly at this stage. • Carbon emissions trading has a crowding-out effect on R&D investment and increases the carbon trading price, which inhibited green technology innovation. • It is necessary to control the scale of carbon emission quota and diversify the subjects of carbon trading. Carbon emissions trading is an important measure to promote high-quality economic development. Based on the panel data of 30 provincial administrative regions in China from 2008 to 2017, this paper uses the difference-in-differences method to analyze the impact of carbon emissions trading on green technology innovation. The results show that: (1) Carbon emissions trading inhibits green technology innovation in the current stage, but greatly reduces carbon emissions and carbon intensity; (2) Carbon price and R&D investment are the mainly working channels, carbon emissions trading has a crowding-out effect on corporates' R&D investment and increases the carbon trading price, which in turn inhibits green technology innovation; (3) Carbon emissions trading has a stronger inhibitory effect on green technology innovation in eastern regions and regions with low emission intensity. Local government competition positively moderates the green technology innovation effect of carbon emissions trading. However, the command-controlled environmental regulations and the scale of the carbon emission quota have opposite effects, with the compatibility of environmental regulation tools remaining to be resolved. Therefore, it is necessary to control the scale of carbon emission quota to diversify the subjects of carbon trading and strengthen the impact of market-incentive environmental regulation tools.

Using the panel data of 30 provincial-level administrative regions in China (excluding Tibet, Hong Kong, Macao, and Taiwan), a threshold regression model was used to empirically analyze the impact of environmental regulation and foreign investment behavior on the amount and intensity of carbon emissions. The results showed that: First, there is a significant inverted "U"-shaped relationship between environmental regulation and carbon emissions. With improved environmental regulation, the positive effects of environmental regulation in reducing the amount and intensity of carbon emissions are more obvious. Next, foreign investment behavior under environmental regulations can reduce the amount and intensity of carbon emissions. Finally, In terms of regional heterogeneity, foreign investment behavior in the eastern and central regions can curb carbon emissions, the opposite effect is seen in the western region. With improved environmental regulations for relatively high–emission intensity regions, foreign direct investment (FDI) in low–emission intensity regions can significantly reduce carbon emissions. It is necessary to formulate differentiated environmental regulation based on regional development. Foreign investment behavior should be standardized to improve the quality of FDI and avoid making China a "pollution paradise" for FDI. [ABSTRACT FROM AUTHOR]

This paper deconstructs industrial green transformation into two aspects, industrial efficiency green transformation and industrial structure green transformation. We examine the impact of digital finance development on industrial green transformation using data from Chinese cities and listed companies. The results showed that: (1) digital finance can contribute to the green transformation of industrial structure distinctly but has an inhibiting effect on the green transformation of industrial efficiency. (2) Digital finance can promote capital-using technological progress and support industrial green transformation with its price effect and scale effect. (3) Higher government environmental preferences and governance capacity can strengthen the green transformation effect of digital finance. Strengthening financial supervision and narrowing the digital divide will help digital finance better support industrial green transformation. Digital finance development can more effectively promote the industrial green transformation of non-SOEs and enterprises with high financing constraints and high financial dependence. (4) Considering the financial attributes and highly polluting characteristics of real estate, digital finance exacerbates the pollution of the real estate industry. This study helps clarify the mechanism of digital finance supporting green development and provides some ideas for China's digital finance development and green economy transformation. • Deconstructing the industry green transformation (IGT) into EFFI and STRU. • Analyzing the synergistic effects of digital finance on the EFFI and STRU of the industry green transformation. • The positive impact of digital finance on the industry green transformation is statistically significant and robust. • The green transformation incentive effect of digital finance has significant heterogeneity.

The rapid development of digital finance has profoundly changed the pattern of economic and social development, which is of great significance for the realization of the harmonious coexistence between humans and nature and for the promotion of sustainable development. This study measures the state of China's provincial ecological footprint from 2011 to 2019, combines the characteristics of digital financial development, and explores whether such development can promote sustainable development from an ecological footprint perspective. The results show that (1) China's provincial ecological footprint per capita, which was continuously aggravated, increased by an average of 29.15% during the sample period. Digital financial development is shown to be able to effectively suppress the ecological footprint, and an environmental inclusion effect is also observed, which helps achieve a win‒win solution for economic development and ecological conservation while promoting environmental equality. Endogeneity tests and other robustness tests indicate that causality holds. (2) Bridging the digital divide, the improvement of environmental constraints and government digital governance capacity can help amplify the marginal effects of digital finance and mitigate the ecological footprint. (3) Green technological innovation and green finance are critical paths to achieve sustainable development. Digital financial development can facilitate green-biased technological innovation and increase the scale of green credit effectiveness, thereby reducing the ecological footprint. In the future, digital technology should be used to achieve the precise sinking of financial resources, while the government's role in guiding sustainable development should be enhanced, the digital divide should be narrowed, and the role of digital finance in supporting sustainable development should be strengthened. • Using the latest improved methodology, this paper measures the provincial ecological footprint in China. • This paper investigates the impact of digital finance development on the ecological footprint. • Digital finance development can effectively mitigate the ecological footprint and has an environmentally inclusive effect. • The reasons for this are the green bias push of digital finance towards technological innovation and the increase in the scale of green credit effectiveness.
