城市可持续发展的关键自然资本研究

城市是社会、经济与环境相互作用最为集中与深刻的区域，随着城市环境问题的日益严重，城市可持续发展成为共同关注的焦点。自然资本在可持续发展体系中起到关键的作用，因此，识别城市系统的关键自然资本是实现城市可持续发展的前提。通过分析城市绿色空间的生态服务功能，结果表明绿色空间是影响城市可持续发展的重要的自然资本。在此基础上，提出了通过保护与投资于绿色空间两种途径实现城市可持续发展的措施与建议。     

绿色经济新理念及中国开展绿色经济研究的思考

联合国里约20周年世界峰会的重要内容之一是倡导绿色经济。绿色经济的概念最早在1989年由英国环境经济学家Pearce提出,但现在的绿色经济却具有全新的意义。本文基于参加联合国有关绿色新政和绿色经济的政策咨询和研究报告,论述了绿色经济的基本背景、三重效益、研究模型以及绿色经济与生活质量的关系,对如何开展中国绿色经济研究进行探讨。首先,文章认为在深入探讨绿色经济前,需要了解当前发展绿色经济的基本背景,明确为什么要发展绿色经济、什么才是我们所需要的绿色经济,以及怎样促进绿色经济发展三个基本问题。其二,绿色经济与褐色经济的情景模拟表明,绿色经济发展模式具有更好的三重底线效益。联合国的T-21模型对过去40年(1970-2010)及未来40年(2010-2050)进行了绿色情景与褐色情景两种模拟,认为在自然资本的环境收益方面,绿色经济发展情景下自然资本的退化得到了基本遏制,而褐色经济发展情景下自然资本的退化会进一步增强;在物质资本的经济收益方面,绿色经济发展情景下,2020年以前经济增长率(2.5%)会低于褐色经济(3%),但从长期平均增长率看绿色经济发展模式(2.5%)可以带来比褐色经济发展模式(2%)更好的经济增长;在人力资本的社会效益方面,在2030年以前绿色经济发展情景下就业机会有小幅减少,但长期来看,绿色经济能够创造与褐色经济同样多的就业机会,甚至可以有小幅的增加(0.6%)。其三,绿色经济研究模型表明,绿色经济投资于自然资本可以实现所需要的经济社会发展与自然资本消耗的脱钩。绿色经济假说是:将资金投资于提高资源能源效率与扩大自然资本两个方面,是否能够导致更好的经济社会发展。基于该理论假设,联合国等国际组织将自然资本引入生产函数,建立了Threshold-21模型,证明绿色经济即投资于自然资本可以实现所需要的经济社会发展与自然资本消耗的脱钩。其四,绿色经济发展模式不仅有利于经济增长,同时能够增加生活质量。绿色经济假说,强调了绿色投资对生活质量有正的影响。通过生态绩效模型、结构方程模型以及典型案例研究等三种方法进行分析,研究表明:减少自然资本消耗可以减少生态环境的治理成本和维护成本、维持与增加自然资本对人类的功能;可以提高自然资本的生产效率,用较少的自然资本投入达到社会稳定所需要的人造资本;可以提高人造资本的服务效率,用一定的物质存量为更多的人服务。其五,开展深化中国绿色经济理论与绿色发展模式的系统研究。联合国等国际组织倡导的绿色经济可以给我们发展中国的绿色经济带来新的启示,笔者认为对中国绿色经济理论与绿色发展模式开展深入和系统的研究,应该包括理论内涵、实证分析、发展情景、行动领域、政策体系等五个依次递进、前后照应的研究模块。     

The Ecology of Empire: Wal-Mart's Rhetoric of Environmental Stewardship and the Constitutive Power of the Multitude

This essay provides a critical account of Wal-Mart's rhetoric of environmental stewardship. By situating this discourse within a new political economy of production and governance that Michael Hardt and Antonio Negri have termed empire, I argue that environmental communication scholars should limit the rush to deploy ideological criticism when explaining the corporation's rhetorical motives. Instead, I advocate reading Wal-Mart's rhetoric as a problem of historical conjunctures, a critical move that seeks to highlight, not only the structural interests of capital, but also the centrality of social antagonism. In the case of Wal-Mart, this means accounting for the increased significance of demand to economic production, changes in the composition of sovereignty, and the transgressive function of environmentalism at the beginning of the twenty-first century.     

Research on challenges and strategies for China’s green economy development

The last 20 years have been the fastest economic developing period of China,and China has made great economic achievements through undertaking international industrial transfer.However,undertaking international industrial transfer has brought about severe environmental problems to China and the process of undertaking international industry transfer is also a process of undertaking international transfer of natural resource consumption and environmental pollution.Nowadays,China has the heaviest ecological burden and highest environmental risk in the world,and is gradually losing international competitive advantages among traditional industries.China is facing unprecedented pressure of economic transformation.Besides the advantages like huge domestic demands and abundant civil capital,China faces more challenges in its green economy development.First,China is still in the middle of industrialization and urbanization processes,hence the huge demands for traditional industries will only last 10-15 more years.Meanwhile,China lacks core technologies for transforming traditional industries,which means these industries will have high shut-down risks.Second,the domestic market share for new green industries is limited,since the market is dominated by traditional energy industries.Third,the value of land,water,mineral,and other natural resources is extremely underestimated because the environmental cost is excluded from the enterprises’cost-benefit calculation.China should foster and expand green industries based on domestic demands,and then strive for competitive advantages in the international market in the future.Therefore,China should focus on the following four points in order to promote green industry development:establishing a forced-upgrading-mechanism for traditional industries,an incentive-development-mechanism for new green industries and a TFP-based(total factor productivity based)economic development evaluation system;promoting the integration of new-type urbanization,new emerging industries,and new employments;taking the model of"technology innovating-patent formulating-standard establishing-market guiding"to enhance the global competitiveness of China’s new emerging industries;and building green consumption patterns in the whole society.     

The disappearing sustainability triangle: community level considerations

This article challenges the application of the sustainability triangle to conceptualise sustainable development by looking at how weak sustainability can be obtained via the reinforcing increase in social capital and natural capital. Sustainable development is often visualised as a triangle consisting of social, environmental, and economic aspects. Would it be possible to conceive a flattened system, with diminishing economic resources or without refilling financial resources? The possibility involves mutual reinforcement between social capital and natural capital. The consideration of the diminishing economic dimension relates to the concept of development without economic growth, such as degrowth, zero-growth, and sustainable growth, that has been revived in the face of the recent economic crisis. Several countries have imposed extreme budget cuts in development collaboration and in other government expenditures. When the economic resource is not at a satisfactory level, can we rely on the reinforcement between social and environmental aspects for sustainability? Although it is not new to acknowledge the contribution of social capital to environmental conservation, research has long ignored the reinforcing relationship between environmental and social dimensions. This article provides a prototype model to demonstrate how social capital and natural capital can reinforce each other. The prototype is studied and verified at the community level using a comparative method. This article concludes with principles and practices that may encourage sustainability with merely the reinforcement between social capital and natural capital.     

崇明生态岛经济指标体系框架研究

崇明生态岛建设是区域可持续发展的新探索，不同于国外的生态城市建设，必须要重视经济发展。为了引导崇明岛走向兼顾环境保护的经济发展道路，从崇明生态经济发展模式出发，提出了一套生态岛的经济指标体系。该指标体系体现了在生态不退化的前提下挖掘经济发展空间，推动自然资本的经济价值实现，打造领先的生态经济模式的发展理念，包括了绿色经济产出等9个基础指标，绿色经济指标、生态价值指标和生态经济指标3个二级指标，最终可计算出生态岛的经济指数。其中，提出了计算绿色经济产出的新思路，即通过建立区域发展的资源环境账簿，实施项目准入机制、环境容量置换和交易机制，避免经济发展对资源环境账簿的透支，从而实现经济产出的绿色化     

生态资本运营机制:基于绿色发展的分析

生态资本是一种重要的资本形态,要实现经济社会的绿色发展,必须重视生态资源节约利用和生态环境建设,建立健全生态资本运营机制,促进生态资本的良性运营,以维持生态资本存量的非减性。本研究在全球绿色转型与绿色发展背景下,采用生态经济学和系统分析方法,探讨如何突破我国经济社会发展面临的资源约束和环境压力,提出建立健全生态资本运营机制的基本构想和分析框架。本研究认为,生态资本运营的内核和目标与绿色发展的要求是完全一致的,完善的生态资本运营机制框架体系应包括生态资本运营的积累机制、转换机制、补偿机制和激励机制。"积累机制"是一般资本运营所具备的步骤,"转换机制"是生态资本运营特有的步骤和内在过程,正是生态资本运营的特殊性,同时需要建立健全"补偿机制"和"激励机制",这是生态资本运营的外在保障措施。因此,要充分调动政府、市场和社会力量参与生态资本运营的积极性,促进生态资本的可持续利用,最终实现经济社会的绿色发展。     

Sustainable Development and Strategic Thinking

From an economic point of view, the industrial economy is efficient to overcome situations of a scarcity of goods. From a technological point of view, the resource efficiency of the manufacturing processes of the industrial economy has been permanently improved during the last 200 years. In addition, cleaner processes have been developed. However, from an ecologic point of view, an increasing world population with increasing consumption has produced a ＂global footprint＂ which approaches the carrying capacity of the planet. A circular economy and its high-value spin-offs-a lake economy and a performance or functional service economy-can fulfil customers＇ needs with considerably less resource consumption, less environmental impairment in production and considerably less end-of-life product waste, especially in situations of affluence, when a considerable stock of physical goods and infrastructures exists. Also, in situations of a scarcity of natural resources, both energy and materials, often characterised by rapidly rising resource prices, the economic actors of a circular economy have a high competitive advantage over the actors of the industrial economy, due to much lower procurement costs for materials and energy. From a social point of view, a circular economy increases the number of skilled jobs in regional enterprises. However, the shift from a linear manufacturing economy to a circular or service economy means a change in economic thinking from flow （throughput） management to stock （asset） management： in a manufacturing economy with largely unsaturated markets, total wealth increases through accumulation as resource throughput （flow） is transformed into a higher stock of goods of better quality （but in a manufacturing economy with largely saturated markets, wealth represented by the stock of goods will no longer increase）; in a circular or service economy, total wealth increases through a smart management of existing physical assets （stock） that are adapted to changes in both technology and customer demand. This second approach not only applies to physical capital but equally to social capital, such as health and education and green GDP. To measure the social wealth of a population, it is not the amount of money spent on schools and hospitals that matters, butif this expenditure has led to a better education of the students, and a better health of the people.     

Plan C： China＇s Development under the Scarcity of Natural Capital

The critical issue of China＇s modernization is whether it can free itself from the traditional modernization plan based on the relatively abundant natural capital, and innovatively create a developmental model of a large country under the scarcity of natural capital. This is why China is so keen on circular economy and economical use of resources. Focused on this issue, this paper summarizes the theoretical elements of the development under the scarcity of natural capital, points out that Plan C is the strategic choice for China＇s future development, emphasizes that China needs to enhance the new industrialization, new urbanization and new modernization based on the restriction of natural capital, and discusses the technological and mechanistic support required to realize the development under the scarcity of natural capital.     

The Role of Institutions and Policy in Enhancing Sustainable Development and Conserving Natural Capital

The use and management of natural capital is critical in all nations, but especially so in poor nations. The role of institutions – chiefly, property rights and pricing systems for natural resources – is pivotal in achieving growth and improved distribution of income and wealth, in understanding environmental degradation, and in seeking improved policy. Particularly useful criteria and indicators of sustainable development relate to `green' output and productivity measures in which the depreciation of natural capital is being considered. Special management problems exist for `critical' components of natural capital to which variants of the precautionary principle must be applied to ensure that our heirs receive an undiminished patrimony.     

First-Person Effects of Emotional and Informational Messages in Strategic Environmental Communications Campaigns

This study examined the first- and third-person effects of emotional and informational messages, particularly relating to the critical issue areas of energy, the environment, and global warming. Due to intense political polarization on such issues, it also explored the role of political party identification. The results of an experiment indicated that informational messages about the environment produced third-person effects, while environmental advertisements meant to evoke emotion caused first-person effects. Moreover, emotional environmental advertisements appealed more to Republicans and those who did not support a political party. As such, indirect, emotional messages appear to represent an opportunity for strategic environmental communicators to design campaigns that resonate with potentially unreceptive audiences.     

环境规制对中国区域绿色经济效率的影响机理研究——基于超效率模型和空间面板计量模型实证分析

基于2000~2015年中国各地区面板数据，在构建绿色经济效率测度指标体系的基础上，运用超效率DEA模型测算中国绿色经济效率，通过对所构建模型普通线性回归得到的残差进行Moran’I指数的计算和检验，发现其存在显著的正相关性，并在此基础上利用空间计量模型分析环境规制水平及其他相关因素对绿色经济效率的影响。结果表明：（1）2000~2015年中国东中西部绿色经济效率和环境规制水平均呈波动上升趋势，并且伴有较为明显的空间差异性特征。但随着时间的推移，各区域绿色经济效率与环境规制水平差异有所减小，呈现收敛的趋势。（2）绿色经济效率与环境规制水平基本呈现出东部地区>中部地区>西部地区的空间分异特征，并随着时间推移两者均出现空间结构不断优化、区域差异逐渐收敛等向好趋势。（3）环境规制水平对绿色经济效率的影响呈现一个先促进后抑制的倒“U”型过程，其中，东中西部地区的环境规制水平对绿色经济效率的影响分别处于不同的阶段；经济发展水平、产业结构高级化和科研水平与绿色经济效率呈现显著的正相关关系，而利用外资水平与绿色经济效率则呈现显著的负相关关系。     

从可持续发展看两大部类生产理论丰富和发展

两大部类生产理论是马克思政治经济学的社会再生产理论，它的潜在假定之一是人类的经济活动没有超过资源与环境的承载能力。在分析传统两大部类生产与自然环境之间关系的基础上，增加了生产环境资源的第0部类，从而构建了面向可持续发展的三大部类生产理论。在社会总资本重新划分的基础上，对三大部类简单再生产的实现条件以及不同生产条件下的三大部类的生产状况进行了研究。     

中国绿色经济发展和机制政策创新研究

通过绿色转型创造新的发展和就业机会对于摆脱经济危机、提升国家竞争力并占据全球制高点和领先地位已经成为全球共识。中国的绿色经济发展将对其未来经济繁荣乃至全球经济发展产生深远影响。转变经济发展方式,实现绿色发展,这不仅是中华民族长远发展的战略性选择和必然需要,也是对全球可持续发展的积极贡献,将对人类发展产生的重要影响。中国正逐步走向绿色发展之路,建设资源节约型社会和环境友好型社会,发展循环经济和低碳经济已经为中国的绿色发展奠定了较为坚实的基础。但是在全球化大背景下,中国正面临各种规模庞大、情况复杂的经济发展、社会转变与环境保护的挑战与机遇,尤其是在宏观层面,绿色发展的体制机制保障尚不健全,制约了中国绿色转型的成效。如何通过恰当的制度创新,进一步推进转型成本效率的提高和体制机制与政策法规质量的改善,加快并深化中国的绿色转型是目前面临的主要问题。本文针对上述问题,系统归纳总结了国际上发展绿色经济的普遍经验以及中国发展绿色经济面临的主要问题和挑战,认为发展绿色经济目前并没有一种通用的模式,解决中国发展绿色经济发展过程中所面临的资源环境制约,必须调整现行以GDP为导向的政府和官员绩效考核体系,平衡目前财政分权体系中财权和事权不对应问题,进一步明确政府和市场的作用及各自起作用的领域,同时,综合应用法律、财政、税收和价格等工具,重视不同手段的综合和协同运用,在不同的发展领域,提出具有适应性和包容性的发展策略,具体来说:①实施"差异化"区域绿色发展战略,针对不同的经济发展和资源环境基础,提出不同的发展重点,同时,建立分区域的绿色发展监测和评估体系;②通过技术进步和管理创新发展绿色农业,以保障农产品安全、生态安全和资源安全为重点,推动农业发展政策、农业生产组织、农业技术服务和农业管理体系的转型;③以资源节约和环境友好为基本原则,实施绿色创新战略,引导和推动工业结构的优化升级;④创建绿色服务业体系;⑤推行绿色消费模式,以绿色消费倒逼绿色经济转型。     

Best Practices in Environmental Communication: A Case Study of Louisiana's Coastal Crisis

This mixed-method case study of environmental communication best practices in Louisiana, USA, identifies trends and approaches as informed by environmental psychology. The results provide key insights for environmental communicators, especially communicators in coastal regions. In-depth interviews with both environmental psychologists and environmental communicators showed that both groups emphasized knowing the audience, telling local stories, building relationships with target audiences and targeted messaging. Both psychologists and communicators also frequently mentioned general messaging concerns of source credibility, avoiding controversial terms and talking about issues, impacts and solutions to which the target audience can relate. A representative survey revealed that Louisiana residents are most interested in hearing about how environmental issues such as climate change, coastal land loss and flooding are affecting their own communities. This finding supports the idea that environmental communicators could do a better job tapping into strong place attachment and sense of community among coastal residents to promote action.     

多因素驱动下的中国城市环境效应分析——基于285个地级及以上城市面板数据

城市化是深刻影响经济社会发展的一项重大社会工程,也是在世界范围内具有一定普遍规律的发展现象,我国多年来快速的城市化取得了积极成效,也积累了严重的环境问题。本研究从经济发展与环境压力的国内外研究出发,以285个地级及以上城市为研究对象,利用调整过的STIRPAT模型,分析这些城市2004—2013年工业SO_2排放强度、工业废水排放强度和工业烟(粉)尘排放强度的驱动因素,结果显示:(1)产业结构调整会产生显著的环境效应,第二产业产值占比对工业污染物排放强度有显著的拉动作用,虽然现阶段我国大多数城市的产业结构向合理化趋势发展,但部分城市仍过分倚重第二产业对经济的拉动,资源消耗大、环境污染严重;(2)城市人口密度与空间规模扩张,使不同规模、不同经济发展水平的城市间出现了"污染转移"现象;(3)我国城市成为外资企业"污染避难所"的问题并不突出,外资企业对工业烟(粉)尘排放相关产业部门降低排放强度有显著的正环境效应;(4)在一定的城市规模区间内,城市规模对工业污染物排放强度有显著影响;(5)285个城市中,大多数城市的工业污染物排放强度的EKC曲线拐点可能已经到来且处于曲线下降阶段,污染反弹的可能性不大,但污染物排放强度拐点的到来并不意味着环境质量改善的拐点也到来。因此,需要正确认识和处理好经济发展与环境保护之间的关系,为城市化发展滞后地区留足发展的生态资本,通过强化环保总体规划、明确生态红线和城市增长边界,合理布局城市产业结构、提高城市土地集约化程度引进绿色资本、实施差异化评估考核等方式推动城市绿色可持续发展。     

It's a Matter of Trust: American Judgments of the Credibility of Informal Communicators on Solutions to Climate Change

Using an October 2013 national probability sample of US adults (N?=?1737), we examine the credibility of informal communicators (e.g. neighbors, co-workers, religious leaders, and health professionals) on solutions to climate change (regulatory and technological solutions). We present our analysis in terms of Kruglanski et al.’s [(2005). Says who? Epistemic authority effects in social judgment. Advances in Experimental Social Psychology, 37, 345–392] epistemic authority framework, which explains dynamics of trust in formal sources of authority with specific expertise (e.g. climate scientists) and informal sources of authority in a person's life (e.g. a priest). Trust in formal communicators (scientists and President Obama) consistently predicts trust in informal communicators (e.g. health professionals), and perceived effectiveness of climate solutions. Results further show that social and demographic groups that do not primarily rely on formal communicators on solutions to climate change instead rely more on various informal communicators. For example, political conservatism positively predicts trust in religious leaders, and religiosity further predicts trust in congregants, neighbors, co-workers, bosses and health professionals on solutions to climate change. Discussion focuses on implications for future research, and recommendations for policy actors, environmental communicators, and social marketers interested in broadening the scope of climate outreach.     

The implications of new information and communication technologies for sustainability

This paper discusses the relationship of new information and communication technologies (ICTs) and sustainable development. It deconstructs popular myths about a sustainable information society. One myth is that telework has reduced the need to travel and hence environmental pollution. The reality is that teleworkers make up only a small share of the total workforce, telework can generate new social relationships and hence the need for more travelling, work-related travel produces only a small amount of the total carbon dioxide emissions, and that the total distance travelled per employee is constantly rising. Another myth is that information economy is weightless and dematerialized which reduces environmental impacts. The energy and resource intensities of the ICT sector are indeed lower than the one of the total economy. The ICT sector also emits less CO₂ than the total economy. But the ICT sector constitutes only a small portion of the total value added and fossil fuel combustion is still the dominant activity of modern industrial economies. Some stakeholders argue that virtual products allow resource, energy, and transport savings. But burning digital music on compact discs and DVDs, printing digital articles and books, etc. results in rebound effects that cause new material and energy impacts, computers have a low life span of 2–3 years, reusable and upgradeable computers and computer equipment are hardly used and might not be as profitable as non-reusable ones, computers are consuming much energy. Alternatives such as energy consumption labels on ICTs and green ICTs that consume less energy contradict dominant economic interests. A sustainable information society is a society that makes use of ICTs and knowledge for fostering a good life for all human beings of current and future generations by strengthening biological diversity, technological usability, economic wealth for all, political participation of all, and cultural wisdom. Achieving a sustainable information society costs, it demands a conscious reduction of profits by not investing in the future of capital, but the future of humans, society, and nature.     

Sustainable management of transboundary river basins: a line of reasoning

This paper identifies a line of reasoning based on a number of concepts and tools to facilitate river basin management, which have been applied in a case study. For long-term sustainable river basin management, a balance is needed between the human use of the river and its basin, the ecological functioning of the river and receiving waters, and the river's capacity to supply goods and services. To find such a balance a framework is needed that illustrates and clarifies possible trade-offs between economic use and environmental supply by integrating scientific information on cause–effect chains on a catchment scale. A number of concepts and tools are proposed as a basis for this framework. The tools are: (1) indicators that describe the complex interactions and processes in rivers; (2) a suite of linked models that predict the economic, environmental and ecological effect of management measures; (3) an evaluation framework to rank different management alternatives on the basis of three objectives: economic efficiency, spatial equity in costs and benefits and environmental quality of the river and receiving lakes. The concept of environmental quality defines the potential of the river environment (i.e. natural capital) to contribute to human welfare. The concept of environmental functions is used to identify societal interest in natural capital. The concept and tools have been applied in a case study involving the evaluation of four management strategies on nutrient abatement in the Rhine basin. The result of the case study is that economic efficiency is in conflict with spatial equity and environmental quality. Spatial equity is in agreement with environmental quality.
