环境规制、能源要素价格与绿色创新效率 ——以长江经济带为例

以“共抓大保护、不搞大开发”为导向推动长江经济带发展,需掌握不同环境规制类型与能源要素价格对长江经济带绿色创新的影响。本文运用面板门槛回归模型聚焦讨论能源要素价格与不同环境规制类型对长江经济带绿色创新效率的影响。研究结果表明:命令控制型环境规制和市场激励型环境规制显著抑制了长江经济带绿色创新效率,不支持“波特假说”;自愿型环境规制显著提高了长江经济带绿色创新效率,验证了“波特假说”。环境规制对长江经济带绿色创新存在显著的空间异质性,且在能源要素价格的不同区间下环境规制带来的影响具有明显差异。不同环境规制下的能源要素价格指标函数均不一致,但存在交叉区间,而在主要环境规制类型下能源要素价格对长江经济带绿色创新效率的影响显著为负。控制变量的研究表明,产业结构和产业规模均在一定程度上显著地积极影响长江经济带绿色创新效率,而社会购买力在一定程度削减了长江经济带绿色创新效率。因此,政府需要进一步深化能源价格市场化改革,多角度、差异化实施环境规制行为,共同发挥社会团体对绿色创新的影响。     

中国省域绿色技术创新与低碳发展协同的测度与推进研究

基于绿色技术创新与低碳发展的协同机理,对中国省域层面两者的协同关系进行测度,并考察了区际绿色技术创新水平的接近关系,结果表明：中国绿色技术创新的整体水平较低;多数省区在推动低碳发展的过程中未能形成绿色技术创新的内生动力,从而导致两大系统的协同度较低;东部沿海、北部沿海和南部沿海是绿色技术创新的“引领区”,而长江中游、黄河中游、东北和西南地区与“引领区”分别存在不同程度的技术接近关系。因此,有必要发挥绿色技术创新“引领区”的核心作用,通过逐层构建区际创新合作网络来增强省域绿色技术创新的内生动力。     

制造业企业绿色组织认同对绿色创新绩效的影响——基于环境承诺与可持续探索/利用实践的链式中介作用

党的十九届四中全会要求进一步激活企业在环境治理中的主体作用,绿色创新对于企业加强环境治理意义重大。基于计划行为理论与组织认同理论,运用315家制造业企业调研数据,分析绿色组织认同对绿色创新绩效的影响,探索环境承诺、可持续探索/利用实践的链式中介作用。结果表明：绿色组织认同未能显著改善绿色创新绩效;环境承诺和可持续利用实践均在绿色组织认同与绿色创新绩效间发挥中介作用,但可持续探索实践在两者间的中介作用只能通过可持续学习导向实现;环境承诺和可持续利用实践在绿色组织认同与绿色创新绩效间发挥链式中介作用。基于上述实证结果,提出旨在提升我国制造业绿色创新绩效的建议。     

基于粮食安全背景下的我国农业补贴绩效评价研究

文章从农业生产效益和农民收入的角度,运用Pearson相关系数和主成分方法构建粮食安全综合指标体系,以WTO框架下的农业补贴对粮食安全的贡献率作为农业补贴绩效评价指标并对其进行分析,得出农业补贴总量对粮食安全的贡献率在波动中呈增长趋势、但近年来趋于稳定等结论。在此基础上,文章提出了优化农业补贴结构的政策建议:以农民种粮收入持续增长为前提调整农业补贴保障粮食安全;根据影响效果和贡献率优化农业补贴结构,提高支农效率。     

Are consumers sensitive to large retailers' sustainable practices? A semiotic analysis in the French context

This paper seeks to discover consumer perceptions related to the adoption of sustainable transport practices by the French large retail industry. Using 20 semi-structured interviews and the semiotic square method, this research sheds light on a set of structured postures of consumers' perceptions according to a semantic axis: conjunction vs. disjunction. The recourse to a socio-semiotic reading here favours a deeper comprehension of the question of consumers' trust in large retailers. It proposes a typology of four distinct virtual strategies responding to the diverse consumer perceptions brought to light: persuasion, rejection, suspicion, and alignment. This leads to a discussion of the strategies offered by different large retailers to meet their consumers' perceptions and expectations. Lastly, the results outline the importance of deploying targeted communication and of aligning sustainable transport practices in accordance with the identified consumer postures.     

Interpretation of the Evaluation Standards of Low Carbon Urban Green Communities

Green community is a direction for modern neighborhood development against the background of the sustainable development strategy with the aim to improve residential environment and provide guidance for low-carbon lifestyle.With the quickening of urbanization,green community development is attracting greater attentions of worldwide research institutions related,especially to the evaluation standards of green communities.This paper interprets the indicators of three major rating systems for green communities; analyzes the evaluation factors with combination of the practice; discusses the application of the assessment indicators;and prospects the construction and development of the green communities in China.     

碳市场:原理、实践和前景

全球气温变暖使得减少二氧化碳等温室气体的排放变得十分必要,由《京都议定书》催生出来的以交易温室气体排放权为主的国际碳市场就是解决这一问题的有益尝试.本文从经济理论出发,分析了国际碳市场的形成基础和运行条件,通过对该市场现状的研究,指出了其存在的问题和今后的发展前景,并对我国如何发展碳市场提出了相关建议.     

Dynamic connectedness of China’s green bonds and asset classes

This paper quantifies the co-movement and time-varying integration between China's green bonds and other asset classes across different time domains using the wavelet coherence and time-frequency connectedness model based on the time-varying parameter VAR (TVP-VAR). First, we predominantly detect a strong positive co-movement of green and conventional bonds, especially in the medium and long term. Second, strong bidirectional spillovers exist between green bonds and treasury, corporate, and financial bonds regardless of the time horizon. Lastly, cross-market spillovers between the green bonds and the stock, energy, low-carbon stock market were quite limited in the short-run but strengthened towards the long-term except during the 2015 China stock market crash and the COVID-19 recession when short-term integration rose sharply. The results document some practical enlightenment for investors and policymakers with various time horizons.
