在乡村振兴战略背景下,应关注农村内部各系统之间的相互协调,以期实现乡村整体水平的优化发展.以安徽省为研究对象,建立农村经济与人居环境发展水平的指标评价体系,运用熵值赋权法、耦合协调模型,计算各市农村经济与人居环境发展水平的综合指数以及二者的协调度.实证结果表明:安徽省农村经济与人居环境水平具有明显的区域差异性,总体协调度相对偏低.因此,应进行不同产业的深度融合,树立绿色引领乡村振兴的理念,健全农村公共设施的投资机制等.  相似文献

Consumers are increasingly worried that their current consumption patterns have negative environmental impacts, which in turn shapes their green purchase intentions. Based on the signaling theory and stimulus–organism–response model, the purpose of this research is to construct a theoretical framework to understand consumer intentions to buy eco-labeled products. Empirical results from 671 questionnaires show that as expected, green advertising receptivity positively affects intention, and the relationship between green advertising receptivity and intention is also moderated by promotion focus and mediated by system trust and personal trust. However, the relationship between green advertising receptivity and purchase intention is not moderated by prevention focus. Hence, this research suggests that stakeholders should conduct truthful green advertising campaigns to dispel consumer suspicion and target different consumers with different green advertising and marketing campaigns to increase sales.  相似文献

China has made significant progress in broadband development. As of September 2018, 95% of China's population was covered by 4G networks. However, our estimates show that nearly 30% of China's families did not use broadband that year. This study attempts to investigate the characteristics of China's broadband left-behind families. Overall, consistent with the findings for other countries, families with a lower socioeconomic status are more likely to be broadband non-adopters. In the information society, older, poorer, rural and less educated families are left behind. It is recommended that the Chinese government shift from a top-down investment-driven policy to a user-centered demand-driven policy to address the digital divide.  相似文献

运用断层理论,从知识获取和关系治理角度,分析焦点企业知识存量如何影响联盟组合分裂断层及分裂断层形成机理。基于焦点企业知识存量、分裂断层、知识转移效率、情景嵌入性之间的关系理论模型框架,认为焦点企业知识存量能够影响联盟组合分裂断层,其中,知识转移效率在这一过程中发挥中介效应,情景嵌入性发挥调节效应。结果发现:焦点企业知识存量与分裂断层之间存在显著负相关关系;知识转移效率能够部分中介焦点企业知识存量与分裂断层之间的关系;情景嵌入性能够正向调节焦点企业知识存量与知识转移效率之间的关系。  相似文献

"一国两制"下粤港澳三地之间的规则衔接,关系到粤港澳大湾区能否更好融合发展.推动规则衔接的实践逐步形成了一些经验,这些做法成为推动粤港澳大湾区规则衔接的"可选模式",但也存在一些问题,需要优化完善.可考虑的思路有三个:一是填补规则空白,建设有利于实践的趋同体系;二是三地规则标准应就高不就低;三是在保持原有规则差异的前提下,内地小切口放宽重点领域的政策.从顶层设计、体制机制创新、互转互认、单向认可、畅通"法律要素"流动、联营合作、探索区域协同立法等方面进行评估分析,探索优化路径.  相似文献

The purpose of this study is to explore how the executive team continuation affects the successor's investment decisions. To this end, we use data of Chinese A‐share listed heritage family enterprises. The findings reveal that executive team continuation has a negative impact on inefficient investment. At the same time, the successor's control rights have a moderating effect on the relationship between the executive team continuation and the successor's investment decisions. In addition, further research shows that the heterogeneity of senior executives' tenure, the number of independent directors, and the distribution of senior executives' professional backgrounds are conducive to explaining the internal mechanism of the continuation of the management team.  相似文献

To avoid the worst effects of global warming, countries agreed to limit warming below 2.0°C and ideally to 1.5°C preindustrial level. This requires countries to drop half of their greenhouse gas emission by 2030 and reach net-zero emission by 2050. In this regard, current study explores the role of green production as a mediator in the impact of managerial environmental awareness, customer pressure, and regulatory control on environmental performance. The data collected from 381 managers was analyzed using structural equation modeling (SEM) technique. Results indicate that customer pressure, regulatory control, and managerial environmental awareness play a pivotal role toward green production, whereas only managerial environmental awareness among them directly influences environmental performance. Green production fully mediates the relationship from customer pressure and regulatory control to environmental performance. However, it partially mediates the relation between managerial environmental awareness and environmental performance. Similarly, the importance of green production for environmental performance is highlighted.  相似文献

This paper explores the role of search and financial frictions in the used capital market. A tractable dynamic general equilibrium model with both frictions is developed to account for procyclicality of reallocation and the price of used capital. Both the aggregate productivity shock and the financial shock can generate procyclical reallocation of used capital. Quantitatively, the financial shock accounts for almost all the variation of used capital reallocation. The aggregate productivity shock is more responsible for the variation of the price of used capital as well as variables outside the used capital market.  相似文献

Drawn on the upper echelons theory, this study investigates how chief executive officer (CEO) hometown identity drives firm green innovation. We propose that CEO hometown identity has a positive impact on a firm's green innovation performance. Furthermore, we explore the moderating role of managerial discretion determined by organizational and environmental factors (i.e., institutional ownership and market complexity). We propose that institutional ownership negatively moderates the positive relationship between CEO hometown identity and green innovation, but market complexity plays a positive moderating role. Using Chinese publicly listed firms from 2002 to 2016 in heavily polluting industries, our findings support these hypotheses. Our research contributes to the upper echelons theory and corporate social responsibility literature and has substantial practical implications.  相似文献

We find strong evidence of time-series and cross-sectional momentum in the long–short returns of a comprehensive sample of anomalies. Strategies that exploit such persistence deliver significant abnormal returns that are robust to the stock momentum effect, cannot be explained by traditional asset-pricing models, and are more pronounced when arbitrage capital is scarcer or market liquidity is lower. Momentum in anomaly returns dissipates but does not reverse, in the long-run. Our findings are consistent with limits-to-arbitrage and slow-moving capital causing mispricing to persist. Supporting this explanation, we find that both the level and persistence of anomaly returns are positively related to idiosyncratic volatility.  相似文献
