To answer these questions, we utilize a difference-in-differences method to detect the impact of the Peaking-Carbon-Dioxide-Emissions policy on the cash flow uncertainty of the energy enterprises and examine the interaction between it and R&D expenditures by using the sample of listed energy enterprises in China during 2008–2021. We find that the energy transition policy has a positive effect on the cash flow uncertainty of the energy enterprises, and the higher cash flow uncertainty after the policy further decreases the R&D expenditure of the energy enterprises. We also find that this negative role of the cash flow uncertainty is partially conducted by the reduction proportion of the long-term loan. In addition, the over-valued enterprises have stronger incentives to squeeze the expenses of R&D activities.

They adversely affect all types of life especially if they contaminate soil or ground when dumped. This research introduces a green clean safe sustainable efficient cheap method for recycling these materials. In the first step in this research, hazardous UMO is recycled as a concrete admixture. Previous research on UMO showed that the use of oil would result in higher air content in concrete, which in turn would result in a decrease in concrete strength. The research eliminates this problem by ensuring correct mixing procedures which will get rid of the increased air content. Hence, concrete strength can be maintained in the structure. The research suggests two simple economic methods to solve the problem. The first is to use an alternative mixing method of concrete to use UMO as a plasticizer without affecting the strength. Enhancement of the strength of concrete was attained by optimizing mixing time. The second method is to recycle steel slag aggregate (SSA) in concrete as coarse aggregate by replacing a certain proportion of natural coarse aggregate. The green use of SSA in concrete was beneficial in improving the properties of concrete containing UMO and was a sustainable solution for reducing the destruction of the environment caused by the depletion of natural resources when natural coarse aggregate is used. The change in mixing method and the use of SSA allowed the recycling of higher amounts of UMO without adversely affecting the fresh, hardened, or transitional plastic properties. Three states of concrete were studied in the research: fresh, plastic transitional, and hardened states. The study showed that the slump test alone is not sufficient to describe the workability of concrete containing UMO. In the transitional plastic state, setting time, bleeding, and finishability were studied. Results show that UMO and SSA can safely be used in concrete without adversely affecting its properties. The initial and final setting times increased by an average of 11 and 22 min respectively. Finishability tests show that the surface smoothness was excellent for UMO mixes containing 1.5% for SSA concretes and 1% for SSA-free mixes. The use of the modified mixing method reduced air content by about 3%. The use of SSA and the modified mixing improved the strength reduction of UMO concretes allowing dosages of about 0.8% to be safely used without losing compressive strength and 1.25% without losing tensile strength. No shrinkage problems are observed in all mixes. Lastly, a special study showed that the combined use will also reduce the overall material direct costs of about 5$ per cubic meter of concrete. Recycling UMO by this method would eliminate the CO<sub>2</sub> emissions produced by the firms that recycle UMO.</p>","PeriodicalId":540,"journal":{"name":"Environment, Development and Sustainability","volume":"20 1","pages":""},"PeriodicalIF":4.9,"publicationDate":"2024-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142268652","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite the benefits of economic growth to individual welfare, its negative environmental consequences necessitate a thorough assessment. The environmental Kuznets curve (EKC), positing an inverted U-shaped relationship between income per capita and environmental degradation, has been extensively studied since its proposition by Grossman and Krueger (Environmental impacts of a North American free trade agreement, National Bureau of Economic Research working paper, 1991. https://doi.org/10.3386/w3914). However, empirical evidence on the validity and shape of the EKC varies due to methodological differences, country-specific dynamics, and other factors. Examining the historical growth paths of individual countries helps explain the mixed findings in empirical EKC research. Long-term data allow researchers to determine the EKC's shape and turning points, aiding policymakers in devising appropriate environmental policies for each economic growth cycle within the framework of global environmental governance. Accordingly, this study contributes to the literature by taking a historical perspective on the EKC, focusing specifically on the United States and the United Kingdom. Drawing on data spanning from 1850, we employ advanced econometric techniques, including fractional frequency flexible Fourier form Dickey–Fuller-type unit root tests and structural breaks unit root tests, to overcome limitations of traditional linearized EKC estimations. Moreover, the classical polynomial regression approach is employed to model the long-term cycles based on the scatterplot inspection of per capita carbon dioxide (CO<sub>2</sub>) and per capita GNP series. Contrary to conventional expectations, our empirical findings do not support the existence of a clear inverted U-shaped EKC relationship between CO<sub>2</sub> emissions and economic growth for either country. Instead, our analysis reveals the presence of multiple regimes, indicating a cyclical pattern where economic growth affects environmental quality with varying severity over time. Furthermore, we demonstrate proper modeling techniques for the EKC, highlighting the importance of identification and misspecification tests. Our study identifies cyclical EKC patterns for both the UK and the USA, with the UK exhibiting two cycles and the USA exhibiting three, shaped by varying economic, social, and technological contexts. By revealing the nuances of the economic growth-environmental degradation nexus for these early developer countries, our study provides valuable insights for policymakers seeking to devise evidence-based and environmentally sustainable growth policies within the framework of global environmental governance.

Currently, relying solely on government governance cannot effectively solve the environmental governance needs of nearly 700 thousand administrative villages in China. Building a collaborative governance model of “government regulation + villagers’ supervision” is the key to achieving successful rural environmental governance. Previous literature mainly used the evolutionary game model under the static reward and punishment mechanism (SRPM) to study the strategy evolution dynamics of village enterprises, the government and villagers. However, the simple model setting makes it difficult for the game system to accurately depict complex real-world problems, and it is concluded that the evolutionary stable strategy (ESS) of the game system can only be pure strategy Nash equilibrium (PSNE). In fact, it is difficult to see the stable strategy of “either this or that”, and most of the strategy combinations with asymptotic stability are mixed strategy Nash equilibrium (MSNE) rather than PSNE, which indicates that the model construction based on the SRPM is problematic. Therefore, this paper expands the SRPM and studies the strategic evolution dynamics of village enterprises, the government and villagers under the dynamic reward and punishment mechanism (DRPM). Theoretical research has shown that MSNE may indeed be the system’s ESS under the DRPM, and a mathematical proof was provided. System simulation has shown that under the SRPM, village enterprises, the government, and villagers all exhibited a periodic strategy selection mode, and the strategies of all parties cannot achieve asymptotic stability. However, under the DRPM, the strategies of all parties eventually tend to stabilize over time, and MSNE is the system’s ESS. This indicates that there is indeed a situation where MSNE is the system’s ESS, and also confirms that the DRPM is indeed a stability improvement compared with the traditional SRPM. Finally, it is suggested that the government should focus on raising the upper limit of punishments for illegal emissions by village enterprises, and should carefully raise the upper limit of rewards for active supervision by villagers.</p>","PeriodicalId":540,"journal":{"name":"Environment, Development and Sustainability","volume":"192 1","pages":""},"PeriodicalIF":4.9,"publicationDate":"2024-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142251983","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
