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]

Marine ecosystems are in serious troubles globally, largely due to the failures of fishery resources management. To restore and conserve fishery ecosystems, we need new and effective governance systems urgently. This research focuses on fisheries management in ancient China. We found that from 5,000 years ago till early modern era, Chinese ancestors had been constantly enthusiastic about sustainable utilization of fisheries resources and natural balance of fishery development. They developed numerous rigorous policies and regulations to guide people to act on natural laws. Being detailed and scientific, the legal systems had gained gratifying enforcement, due to official efforts and folks' voluntary participation in resource management. In-depth analyses show that people's consciousness of ecological conservation was derived from the edification of kinds of ancient eco-ethical wisdom, such as totemism, nature worship, Zhou Yi, Taoism, Buddhism, Confucianism, Mohism, etc. All this Chinese classical wisdom have the same cores: 'Nature and Man in One' spirit, frugality and 'All things are equal' concept. The findings show that eco-ethical thinking is never inconsistent with social ethic systems, and it's of great importance to give legal effect to usual ecological moral claims and eco-ethical requirements of the public in protecting the environment. The eco-ethical wisdom is efficient in assisting and urging people to fulfill humans' obligation for nature. Finally, it's believed that present world fisheries management will benefit a lot from all these ancient Chinese thoughts and practices. People are expected to make the most of the eco-ethical wisdom, strengthen fishery legislation and fully stimulate their voluntary participation in both marine fishery resources conservation and fishery cyclic economy.

Abstract: The Bohai Sea (BHS), located at the western boundary of the NW Pacific, is a shallow semienclosed sea with an area of about 77×103 km2 and average depth of 18m, surrounded by fast-developing economic zones and populous lands. Through the Bohai Strait, the BHS connects to the Yellow Sea, one of the 50 large marine ecosystems in the world ocean. The hydrographic conditions there are substantially influenced by river discharges, wind–tide–thermohaline circulation, stratification in summer, and mixing in winter. During the period of 1960–1996, temperature, salinity, dissolved inorganic nitrogen, and the N:P ratio increased from 0.005 to 0.013°C year−1, 0.04 to 0.13 year−1, 0.45 to 0.61μmolL−1 year−1, and 1.27 to 1.40year−1, respectively; while dissolved oxygen, phosphorus, silicon, and the Si:N ratio decreased from −1.59 to −2.30μmolL−1 year−1, −0.007 to −0.011μmolL−1 year−1, −0.385 to −0.602μmolL−1 year−1, and −0.064 to −0.324year−1, respectively. These changes were primarily caused by a reduced freshwater inflow. Since 1985, the concentrations of P and Si, and the Si:N ratio, have dropped to near-critical levels for diatom growth, while the N:P ratio has been below the Redfield ratio. These changes not only have had an influence on phytoplankton production, but also can decrease recruitment of the Penaeid prawn (Penaeus chinensis) and change fish community structure and diversity.
