Environment and Personal Well-being in Urban China

The aim of this study is to examine the relationship between environment and personal well-being using a sample of 562 urban employees from three cities in Liaoning province in the People’s Republic of China.In contrast to previous studies,this study controlled positive affectivity (PA),negative affectivity (NA),job satisfaction and Big Five personality traits.In addition,the research variables of personal well-being index (PWI),positive affectivity,negative affectivity,job satisfaction,Big Five,and environmental satisfaction are measured with multi-item scales.The research finds that environmental satisfaction is positively related to personal well-being,suggesting that improvement of the natural surroundings in the cities can improve people’s well-being.     

Impacts of Suburbanization on Urban Eco-environment of Xi’an in China

Suburbanization in large cities is an important phenomenon in the process of urbanization development in China in recent decades,which plays a very important role in promoting city development,whereas some side effects on the eco-environment appeared at the same time.This paper,taking Xi’an City in China as a case study site,analyzed the features of population suburbanization and industry suburbanization and pointed out the impacts of suburbanization on urban eco-environment.Based on the research,suggestions of countermeasures for urban planning and municipal management of Xi’an City in protecting urban eco-environment and conserving natural ecology were put forward in the end.     

泛长江三角洲地区经济发展与生态环境耦合协调关系分析

以泛长三角地区41个地级市以上的政区为例,运用改进熵值法计算经济发展及生态环境系统的综合得分,并运用耦合协调模型分析1999~2013年两系统的耦合协调度及其演变,最后通过经济发展与生态环境系统得分排名划分4种类型,提出未来泛长江三角洲经济发展分类指导建议。研究结果表明:(1)1999~2013年泛长三角地区经济发展与生态环境的耦合度C∈[0.5,0.8],整体位于磨合阶段;而系统协调度D∈[0.3,0.5],整体属于中度耦合协调;(2)1999~2013年泛长三角经济发展与生态环境系统耦合协调度呈现上升态势,但经济发展与生态环境系统综合评价值仍表现负相关的特征;(3)未来苏南地区、皖江地区、杭甬地区需要进一步调整产业分布结构,提升城市经济发展环境;而苏北地区、皖西地区、浙西南地区需要进一步增加城市经济发展的软、硬实力各种要素的投入,并将城市生态环境优势转化为经济增长优势。     

收入差距是否影响环境质量?——国内外研究综述

近年来,收入差距扩大与环境质量恶化成为许多国家同时面临的问题,也让一些经济学家开始思考,这两者之间是否存在关联。继20世纪90年代环境库兹涅茨曲线提出以来,一些研究发现不仅收入的绝对水平会对环境质量产生影响,收入差距对环境质量也有影响。本文对这一课题的理论研究进行了梳理,发现现有理论中收入差距对环境质量的影响途径主要有三条。第一条途径是消费者途径,即收入差距影响着以消费为主的个人经济行为,进一步影响着社会消费总量和消费结构,及其过程中产生的污染总量。第二条途径是企业途径,即认为收入差距的扩大会削弱环保型产品的正外部性,不利于环保技术的创新活动,对未来环境质量的改善产生动态影响。第三条途径是政府途径,即认为收入差距会影响相关的环境政策方式与强度选择;而且在不同的社会政策决策机制下,收入差距对环境政策的影响也是不同的,现有的社会决策机制分析框架主要有两种——权利权重型社会决策规则和简单多数规则。此外,本文还对现存的主要实证研究进行了总结,发现大多数研究结论都支持收入差距对环境质量存在着影响,但这种影响并不是线性的。一方面,收入差距对环境的影响与研究的污染物种类有关,大多数研究都显示,收入不平等对CO 2排放和土壤污染存在着负向影响,但有关收入差距对空气污染和水污染影响的研究结论并不统一或并不显著。另一方面,这种影响还与经济发展水平相关,在高收入国家与低收入国家是不同的,存在着阈值效应。最后本文总结了针对中国的研究现状,讨论了其在我国的适用性。     

工业水环境监管契约研究

对工业污水排放的有效监管是水环境保护的重要环节。分析了我国目前监管主体所处的困境,考虑中央监察与公众参与的监督约束作用,构建了水环境监管体系。并设计出具有激励约束惩罚效力的水环境监管契约,建立委托 代理模型,通过求解得出监管契约中污水排放标准、监管频率、补偿额度以及罚款数额的最优值。在此基础上,以太湖流域两个成本类型差异较大的印染企业为例,定量设计两级水环境监管契约,分析公众参与程度和地方政府庇护企业程度对契约取值的影响。结果表明：提高公众参与程度可以有效降低罚款额度,削减政企矛盾;当公众参与程度和惩罚额度一定时,通过环境问责等制度降低地方政府庇护企业的程度,能够减小监管频率,从而削减监管执行成本     

An in-depth view of climate change:addressing climate change while making a transition on the development mode

While fossil fuels greatly contribute to human society,they pose great challenges to natural resources,the environment,and climate change.Developed countries,like the United States,formulated strategic measures to ensure their sustainable development and leading positions in the world.These measures include new green policies,development of shale gas,revitalization of nuclear power,energy independence,reindustrialization,and new low-carbon development based on a combination of Internet technology and renewable energy.Developing countries are also trying to introduce balanced strategies of poverty alleviation and sustainable development.Globally,industrial civilization is being transformed to ecological civilization and green,low-carbon development is a global trend.Addressing climate change provides new strategic factors to further this development.China should take substantial actions to realize sustainable development in a new road:China is in the critical stage of changing its development mode,so it is vital to choose an appropriate development path.This extensive development comes at the high price of consuming too much resources and scarring the environment.Mitigation and adaptation strategies for addressing climate change can help the transition of development.Based on the analysis of the development data of developed countries,the author introduces the concept of"two-type developed countries"with an understanding that not all developed countries must take the same development mode.He also holds the view that China should achieve modernization in a more energy-saving and more carbon-efficient manner compared with that of two-type developed countries.An analysis of"two competitions"that China is facing shows that changing the developing mode is urgent and China should grasp this opportunity in the next five to ten years,which is a key period for this transition.This paper discusses the low-carbon development goals and the three-step process.Low-carbon development does not necessarily restrict economic development.It,however,can expedite the transition of the development mode and this is a low-carbon and green development path.Transition of the development mode includes implementation of China’s green and low-carbon energy strategies,low-carbon society construction,development of agriculture and forestry,garbage sorting and utilization,innovation of urbanization,etc.Improvement of national infrastructure construction includes water safety,environment and climate monitoring system,intelligent energy web,basic database,etc.Addressing climate change can significantly improve the nation’s basic research level.In summary,it mitigates backward production capability,extensive development,and environmental damage while promoting technological advancement,scientific development,and ecological civilization.
