This article explores the impact mechanism of different types of environmental regulations on corporate green technology innovation (GTI). The research focuses on analyzing three types of environmental regulations: command based environmental regulation (ER1), market-oriented environmental regulation (ER2), and voluntary environmental regulation (ER3), and how they affect corporate GTI. This study selected enterprise GTI as the dependent variable and measured it by the number of applications for green invention patents and green utility model patents. The independent variables are the three types of environmental regulations mentioned above. According to data from Chinese A-share listed companies. Using benchmark regression models to analyze the impact of different environmental regulations on GTI, and constructing a moderating effect model to study the role of corporate R&D investment and government support in the process of environmental regulations affecting GTI. The results indicate that (1) ER1, ER2, and ER3 can all promote enterprise GTI, and the three environmental regulatory methods have a better synergistic effect. (2) R&D investment has a positive correlation with the relationship between ER2 and GTI, and a negative correlation with ER 3 and ER 1. (3) There are differences in the GTI performance of enterprises in different regions, ownership nature, factor density, and industry types under the influence of environmental regulations. (4) The impact of environmental regulatory policies on corporate GTI is mainly short-term. This study provides a new perspective on how environmental regulations affect corporate GTI, especially in the context of developing countries like China. The research findings emphasize the role of different types of environmental regulations in incentivizing corporate GTI, while also pointing out factors that governments need to consider when formulating environmental policies, such as regional differences and corporate characteristics, which are of great significance for promoting green development of enterprises and achieving broader sustainable development goals.

With rapid economic expansion, China is faced with environmental challenges like air pollution and greenhouse gas emissions. Shifting from conventional fossil fuels to renewable energy (REN) sources is critical to facilitate sustainable development in China. Compared to coal and oil, REN such as solar and wind energy emit less carbon emissions. Fostering innovation of REN technologies is thus essential for China's green transition. This study aims to analyze the impact of REN technology innovation on China's economic growth using panel data models. The results demonstrate that advancing REN technologies significantly promotes GDP increase in China. Targeted policy incentives must be implemented to accelerate REN technology progression and adoption across the country. Transitioning towards REN systems will be instrumental for China to achieve environmental sustainability while maintaining economic growth. [ABSTRACT FROM AUTHOR]

This paper summarizes the changing states of the food resources in the Yellow Sea Large Marine Ecosystem under multiple stressors from 1958 to 2015, including the changing states of biomass yields, species composition, trophic level and biodiversity. The results show that the changing trends were contrary to expectation. There were no significant declines in biomass yields, trophic level and biodiversity after the 1980s. The major decline observed occurred before the 1980s. However, the species composition changed a lot, that is, over the past half century there were two different types of species shift in YSLME under multiple stresses. One was from demersal, high value species to pelagic, lower value species shift during 1958–59 to 1998–2000, and the other was from pelagic, lower value species to demersal, low value species shift during 1998–2000–2014-15. For future sustainable development, it is still necessary to further strengthen adaptive management. [ABSTRACT FROM AUTHOR]
