论城市旅游中央游憩区(RBD)的开发

中央游憩区是现代城市旅游的核心区域之一，主要包括城市商业区和城市游憩区两个区域。其旅游产品有着突出的旅游功能和旅游吸引力。对中央游憩区的开发，要从旅游规划、旅游资源、客源市场、综合环境等方面整体考虑。才能更好发挥其旅游价值，促进城市旅游的可持续发展。     

低碳视角下发展绿色物流的思考

从我国物流业碳排放现状着手,分析了低碳视角下发展绿色物流的意义以及存在的问题,在此基础上从基础设施建设及低碳化设备应用、行业政策法规完善及标准制定、低碳物流理念普及与低碳人才培养、外部激励机制推进、低碳物流技术研发、企业低碳创新能力提升等方面提出了低碳视角下发展绿色物流的几点思考。     

考虑社会责任的异质有限理性制造商产量博弈均衡复杂动力学分析

通过考虑消费者剩余,企业利润中引入承担社会责任参数,建立了具有异质性有限理性的古诺寡头博弈竞争模型,分析利润相关参数对系统博弈均衡稳定性的影响,并进行了数值模拟。研究表明单方有限理性系统比双方有限理性系统稳定。产品成本超过一定阈值应避免产量竞争,可以通过承担社会责任,提升产品价格来增加利润,但当企业承担社会责任增加时,系统稳定性降低。此时降低调整产量的速度,观察竞争对手产量调整速度,避免系统进入混沌状态,失去最优产量优势。     

“一带一路”框架下的中拉绿色产品贸易:特征、比较优势与出口潜力

在“双循环”背景下,加强“一带一路”建设对中国深化对外开放意义重大,促进中拉绿色贸易符合双方利益,可为“一带一路”延伸至拉美创造新的合作增长点。本文使用2002年至2018年的货物贸易数据,分析了中拉共建“一带一路”过程中中拉绿色产品贸易的特征和趋势,并重点研究了中国绿色产品对拉美的出口潜力。通过使用双边显示性比较优势指数和出口潜力矩阵,文章发现,在现有的中拉货物贸易结构中,绿色产品贸易所占比重较低,贸易对象高度集中,但随着双方经贸合作的全面深化、特别是“一带一路”延伸至拉美,双边绿色产品贸易金额和种类都在稳定上升。尽管中国绿色产品在拉美市场面临着地理距离遥远、市场竞争激烈等客观困难,但中国的优势产品已成功出口到拉美。中国的出口潜力更多地取决于拉美地区的市场需求,一旦拉美对绿色产品的需求提升,那么中国就具备进一步扩大向拉美出口该类产品的潜力。此外,出口潜力矩阵也找出了部分对拉美市场而言具备不可替代性的中国产品,这也将成为中国潜在的对拉出口重点绿色产品。     

基于BIM的绿色建筑预评估体系研究

随着我国经济的高速发展,人们的环保意识越来越强,因此,绿色建筑在我国政治、经济、生活中的地位越来越突出和重要,俨然成为公众生活中不可或缺的重要构成部分。论文主要对建筑信息模型(BIM)技术的主要特点进行了分析,并且提出了BIM技术在建筑节能设计评估中运用的方法,希望为我国对基于BIM的绿色建筑预评估体系的研究提供一些参考与帮助。     

绿色维修技术在汽车处理中的应用价值

随着我国经济的快速发展,人们的生活质量得到改善,汽车保有量逐年递增。汽车修理工作的重要性日益突显,甚至成为影响社会发展的主要因素。在汽车修理工作中,一是要合理选择汽车维修技术;二是要重视汽车的危害因素,如环境污染。所以工作人员应该合理应用绿色维修技术,减少污染问题的出现。论文主要阐述在汽车处理中绿色维修技术的应用价值,仅供参考。     

Minimum Quality Standards under Asymmetric Duopoly with Endogenous Quality Ordering: A Note

In this note, we revisit minimum quality standards (MQS) under a vertically differentiated duopoly. We generalize the model in Ronnen (1991) and Valletti (2000) by introducing asymmetry into the fixed cost of quality improvement and by explicitly taking into account the endogeneity of quality ordering. In the generalized model, we show that the results derived by Ronnen (1991) and Valletti (2000) are largely robust.     

Environmental Product Differentiation and Environmental Awareness

In this paper, we have considered a duopolistic model of environmental product differentiation with two types of consumers (green and brown) to analyze how environmental awareness affects the environment. “Green” consumers value the physical and environmental attributes of the good they purchase while “brown” consumers only value the physical attributes. We find that more environmental awareness may not be good news for the environment as the firm that produces the good without environmental attributes may increase its sales. The result depends on the degree of product differentiation and the cost to achieve it. Social welfare can also be inversely related to environmental awareness if the negative environmental effect dominates the positive market effect.      

Natural resource accounting for Indian states — Illustrating the case of forest resources

Our main objective is to set out and apply a SEEA-based methodology to reflect the true value of forest resources in India's national and state accounts. We establish that a “top-down” approach using available national databases is both feasible and desirable from a policy perspective. In this paper, we address four components of value creation in forests: timber production, carbon storage, fuelwood usage, and the harvesting of non-timber forest products. The results of our analysis suggest that prevailing measures of national income in India underestimate the contribution of forests to income. The income accounts of the Northeastern states in particular are significantly understated by these traditional (GDP/GSDP) measures. We are also able to identify some states which performed poorly in the context of our sustainability framework, reflecting natural capital losses due to degradation and deforestation. Our results highlight the need to integrate natural resource accounting into the national accounting framework in order to generate appropriate signals for sustainable forest management and for the conservation of forest resources which are widely used by the poor in India, as well as being significant stores of national wealth.
