中国农业生态效率评价方法与实证——基于非期望产出的SBM模型分析

生态效率是衡量经济与资源环境协调发展的重要指标.基于将农业面源污染作为非期望产出的考量,在对传统DEA模型进行修正的基础上,采用非径向、非角度的SBM模型对中国30个省份的农业生态效率进行了测算,并给出了农业生态效率的改善途径.研究结果表明:1998-2009年中国农业生态效率虽然呈现缓慢上升态势,但整体仍处于较低水平,除北京、上海、海南、重庆外,其余省市都需要改变投入和产出来优化农业生态效率;资源的过度消耗和环境污染物的过量排放是农业生态效率损失的主要原因.提高资源利用效率、降低资源消耗量和环境污染物的排放量是农业生态效率改善的重要途径.     

基于物质流分析和数据包络分析的区域生态效率评价——以江苏省为例

区域生态效率(eco-efficiency)评价是考量区域可持发展的重要内容.基于物质流分析(material flow analysis, MFA)构建区域生态效率评价指标体系,并将污染物排放作为一种非期望输入引入到数据包络分析(data envelopment analysis, DEA)模型中,以江苏省(1990～2005年)为例进行生态效率分析评价.结果表明,江苏省的区域生态效率在1990～2005年期间呈现逐步上升的趋势.但是,同期的总物质投入(total material input, TMI)、物质需求总量(total material requirement, TMR)和污染物排放量也呈上升趋势.因此,江苏省社会经济发展和环境影响总体上呈现"弱脱钩(weak de-link)".     

Urgency,development stage and coordination degree analysis to support differentiation management of water pollution emission control and economic development in the eastern coastal area of China

The eastern coastal areas of China have high-density population, developed society and economy, and large water pollution emissions. How to reduce water pollution and realize the coordinated development of the economy and environment has become the national focus. Effective environmental policies should consider regional differences in development stage and sustainability performance. Here, we first analyzed the water pollution emissions intensity of the eastern coastal areas of China and the urgency of emissions reduction using 8-year environmental statistics from 2003 to 2010. We characterized development stages of the eastern coastal areas based on the relationships between water pollution emissions intensity and economic development. Further, we built a coordination degree index of economic development and water environment protection as a measure of sustainability. Results show that water pollution emissions intensity decreases as the economy grows from 2003 to 2010. The less-developed regions have a better coordination degree than some more-developed regions, especially those most-developed ones (e.g., Shanghai show more pressures on long-term sustainability than Hebei). The less-developed regions should take advantage of economic growth to invest more advanced environment protection technologies. The more-developed regions need to upgrade its economic structures and municipal infrastructures. Overall, the study provided a comprehensive approach to understand regional difference in development stage and sustainability performance in the eastern coastal region of China as well as the need of different environmental policies to reduce water pollution emissions.

提高长江经济带工业生态效率,是促进工业向绿色转型升级的重要路径,更是促进区域经济与生态协调发展的重要选择。将工业生态系统分解为工业经济、环境、能源三个子系统,以2009—2013年9省2市的工业数据为基础,采用网络DEA模型对长江经济带9省2市的工业生态效率及三个子系统效率进行评价。结果显示:(1)长江经济带工业生态效率水平整体呈上升趋势,且自上游至下游效率水平依次递增。(2)长江经济带工业经济子系统效率水平相对稳定,区域内以下游最高、上游最低;环境子系统效率水平呈增长趋势,区域内以下游最高、中游最低;能源子系统效率水平呈增长趋势,区域内以下游最高、上游最低;(3)收敛性检验显示,长江经济带工业生态效率及各子系统效率呈收敛趋势,其中工业经济子系统效率呈相对稳定的状态。研究为长江经济带工业生态效率的改善提出了可操作性的政策建议。     

基于生态效率的辽宁省循环经济分析

生态效率与循环经济相辅相成。基于区域生态效率评价是考量区域循环经济的重要内容,又基于目前对于循环经济与生态效率结合的实证研究相对较少,因此,以生态效率理论为基础,对我国最早开展循环经济的试点省份——辽宁省的循环经济发展作以综合衡量。通过生态效率度量模型与循环经济度量模型,以辽宁省1990～2008年数据为基础,运用基于熵权的TOPSIS方法,分别计算了19a间辽宁省各年的资源效率、环境效率、生态效率,进而综合评价了辽宁省循环经济发展轨迹。研究表明：在19a间,辽宁省生态效率总体呈现波动上升态势,经历了传统经济发展模式——末端治理模式——循环经济模式的转变;19a间,辽宁省循环经济发展状态总体上处于循环性不断增强的状态,即经济发展的同时,环境压力不断减小。研究证明了辽宁省2002年实行循环经济以来取得了明显成效,对全国尤其是东北地区发展循环经济,走新型工业化道路具有重要的示范意义。     

Study on the interaction and relation of society,economy and environment based on PCA–VAR model: As a case study of the Bohai Rim region,China

Ongoing success throughout regional development is contingent on maintaining the function, quality and harmony progress in society, economy and environment domains, so exploring the interaction and relation among them should be considerable significant. The model by coupling principal component analysis and vector autoregressive, which relate the aggregated values and dynamic analysis among factors, is proposed to achieve the qualitative and quantitative analysis of interaction and relation among society, economy and environment subsystem, providing a framework to conceptualize the influences among their changes and simulate the future scenarios in the Bohai Rim region. The impulse response analysis and variance decomposition of vector autoregressive method, in particular, permit dynamic interaction between every two systems and display clear decomposition of contribution for each change, respectively. This study results show that: there is a virtuous circle of promotion between economic growth and social progress no matter which is regarded as the endogenous variable during the study period, and yet the negative effect to environmental changes had been produced; what the improvement of social and environmental situation need most might be advancing its own progress; it is also reflected that the entire complicated system walk on the path of unsustainable development due to the evident disequilibrium of three subsystems; and the scenario analysis results obviously tell that in order to attain coordinated development, the annual growth rate of 12% to 16% of overall environmental level should be anticipated along with 8% of social and economic level improve. The study guide future possibilities for relatively more harmonious interconnections among social, economic and the environmental development.     

中国“三大经济模式”的可持续发展——以真实发展指标对6个典型城市的可持续性评估为例

“珠江模式”、“温州模式”、“苏南模式”的发源地是中国经济发展的前沿地带,评估其可持续发展情况对中国经济的下一步发展具有重要的指导意义.本文采用真实发展指标(GPI),评估了1995—2012年中国“三大经济模式”下广州、深圳、温州、苏州、无锡、常州6个典型城市的可持续发展情况.结果表明: 研究期间,6个城市的GDP呈指数型增长,但GPI在1995—2005年间并无增长,2005年以后才开始上升,GPI与GDP的差距越来越大;“珠江模式”虽然经济增长迅猛,但经济、社会、环境损耗突出,实现其可持续发展必须解决分配不均、交通拥堵、环境污染等问题;“温州模式”人均GPI后期与其他城市拉开差距,发展后劲不足,贫富差距突出,社会账户水平较低且增长缓慢,发展方式亟待转型;“苏南模式”虽然资源消耗较为突出,但各类损耗处于中等水平,经济增长迅猛,社会账户水平稳步提高,GPI所反映出的真实发展水平也较高,相对具有可持续发展潜力.“三大经济模式”应持续关注可持续发展的经济、环境与社会三大方面,而“珠江模式”、“温州模式”应更积极地寻求发展转型.     

How Can the Eco‐efficiency of a Region be Measured and Monitored?

The concept of eco-efficiency is commonly referred to as a business link to sustainable development. In this article, ecoefficiency is examined at a regional level as an approach to promoting the competitiveness of economic activities in the Finnish Kymenlaakso region and mitigating their harmful impacts on the environment. The aim is to develop appropriate indicators for monitoring changes in the eco-efficiency of the region. A starting point is to produce indicators for the environmental and economic dimensions of regional development and use them for measuring regional eco-efficiency. The environmental impact indicators are based on a life-cycle assessment method, producing different types of environmental impact indicators: pressure indicators (e.g., emissions of CO₂), impact category indicators (e.g., CO₂ equivalents in the case of climate change), and a total impact indicator (aggregating different impact category indicator results into a single value). Environmental impact indicators based on direct material input, total material input, and total material requirement of the Kymenlaakso region are also assessed. The economic indicators used are the gross domestic product, the value added, and the output of the main economic sectors of Kymenlaakso. In the eco-efficiency assessment, the economic and environmental impact indicators are monitored in the same graph. In a few cases eco-efficiency ratios can also be calculated (the economic indicators are divided by the environmental indicators). Output (= value added + intermediate consumption) is used as an economic indicator related to the environmental impact indicators, which also cover the upstream processes of the region's activities. In the article, we also discuss the strengths and weaknesses of using the different environmental impact indicators.     

The Sustainability Balanced Scorecard as a Framework for Eco-efficiency Analysis

To provide valuable support for successful decision-making, managers need a balanced set of financial and nonfinancial measures that represent different requirements, strategic goals, strategies, resources, and capabilities and the causal relationships between these domains. The balanced scorecard is such a measurement system. As an open system the balanced scorecard facilitates the consideration of sustainability issues. But enhanced balanced scorecards require a new type of data. This is where eco-efficiency analysis comes into play.
This article discusses the relationship between so-called sustainability balanced scorecards and eco-efficiency analysis. Eco-efficiency analysis not only provides a data source for sustainability balanced scorecards; in the perspective of environmental information systems it also serves as a link between the balanced scorecard and corporate environmental accounting systems so that eco-efficiency as a component of an environmental information system becomes an adapter with two interfaces, which are characterized in this article. The main focus is on the principle of cause and effect, its different forms, and the implications for the design of appropriate information system components.     

Assessing regional sustainable development through an integration of nonlinear principal component analysis and Gram Schmidt orthogonalization

The regional sustainable development level (SDL), sustainability of regional development (SRD) and system coordination (SC) make up the triangular truss of regional sustainable development assessment, but it is debated how should traditional practice best weight and calculate the whole sustainable development system level. The Bohai Rim, covering three provinces and two municipalities in China, lies in a region that is sensitive to profound conflict between socioeconomic development and environment pollution in the process of sustainable development. Considering the defects of traditional models and the multidimensionality of regional sustainability issues, we proposed an integrated model of nonlinear principal component analysis and Gram Schmidt orthogonalization and presented a novel regional sustainable development assessment method and framework from three perspectives for the society–economy–environment system of the Bohai Rim region. The results show that: (a) the integration of nonlinear principal component analysis and Gram Schmidt orthogonalization can well remedy the defects of traditional methods and provide a more objective conceptual framework; (b) the sustainability of regional development and system coordination models graphically demonstrate the essence and connotation of a dynamic sustainable development system; (c) the empirical study demonstrated that the Bohai Rim region has experienced a distinct development period in which the SRD experienced a steady decline and the SDL and SC generally increased; (d) the coordination ability can be improved by a decline in the environmental sustainability, which reveals the importance of environment subsystem optimization; and (e) the weight distribution of variables demonstrates that the most significant factors affecting sustainable development are the indicators from the dimensions of people's standard of living, economic structure and environmental pollution. This study enriches the sustainable development assessment theory and methodology, and lays the foundation for further sustainable development research in the Bohai Rim region.     

Eco-efficiency and Its xsTerminology

Eco-efficiency has been defined as a general goal of creating value while decreasing environmental impact. Leaving out the normative part of this concept, the empirical part refers to a ratio between environmental impact and economic cost or value. Two basic choices must be made in defining practical eco-efficiency: which variable is in the denominator and which is in the numerator; and whether to specify environmental impact or improvement and value created or cost. Distinguishing between two situations, the general one of value creation and the specific one of environmental improvement efforts, and leaving the numerator-denominator choice to the user, as diverging practices have developed, four basic types of ecoefficiency result: environmental intensity and environmental productivity in the realm of value creation; and environmental improvement cost and environmental cost-effectiveness in the realm of environmental improvement measures.     

Multi-criteria decision making approaches for green supply chains: a review

Designing Green Supply Chains (GSCs) requires complex decision-support models that can deal with multiple dimensions of sustainability while taking into account specific characteristics of products and their supply chain. Multi-Criteria Decision Making (MCDM) approaches can be used to quantify trade-offs between economic, social, and environmental criteria i.e. to identify green production options. The aim of this paper is to review the use of MCDM approaches for designing efficient and effective GSCs. We develop a conceptual framework to find relevant publications and to categorise papers with respect to decision problems, indicators, and MCDM approaches. The analysis shows that (1) the use of MCDM approaches for designing GSCs is a rather new but emerging research field, (2) most of the publications focus on production and distribution problems, and there are only a few inventory models with environmental considerations, (3) the majority of papers assume all data to be deterministic, (4) little attention has been given to minimisation of waste, (5) numerous indicators are used to account for eco-efficiency, indicating the lack of standards. This study, therefore, identifies the need for more multi-criteria models for real-life GSCs, especially with inclusion of uncertainty in parameters that are associated with GSCs.

HOW TO CONNECT BIOETHICS AND ENVIRONMENTAL ETHICS: HEALTH, SUSTAINABILITY, AND JUSTICE

In this paper, I explore one way to bring bioethics and environmental ethics closer together. I focus on a question at the interface of health, sustainability, and justice: How well does a society promote health with the use of no more than a just share of environmental capacity? To address this question, I propose and discuss a mode of assessment that combines a measurement of population health, an estimate of environmental sustainability, and an assumption about what constitutes a fair or just share. This mode of assessment provides an estimate of the just and sustainable life expectancy of a population. It could be used to monitor how well a particular society promotes health within just environmental limits. It could also serve as a source of information that stakeholders use when they deliberate about programs, policies, and technologies. The purpose of this work is to focus attention on an ethical task: the need to fashion institutions and forms of life that promote health in ways that recognize the claims of sustainability and justice.     

基于情景分析的区域能源-经济-环境耦合研究-以甘肃省为例

区域发展目标是减少人类活动对于生态环境的胁迫,实现区域社会经济活动的非物质化,即在实现一定的经济增长目标的同时尽可能地减少进入经济系统的物质和能量流动.本研究以甘肃省为案例,基于情景分析方法,分别以地区生产总值表征经济,以CO₂排放表征环境影响,研究了区域能源经济系统要素之间的耦度关系,探析了实现解耦过程的具体路径.研究结果表明区域能源经济环境系统的三要素之间呈现紧密关联性,如果维持现有的发展方式,虽然其生产效率在不断提高,但对环境保持较大的胁迫.在区域可持续发展的能源供应设计中,应积极探索以建立可再生能源为主要目标导向的能源供应系统,只有同时实现了经济活动、资源利用、环境影响之间的系统“解耦”,才能实现区域可持续发展的目标愿景.     

Socioeconomic Metabolism and Colonization of Natural Processes in SangSaeng Village: Material and Energy Flows, Land Use, and Cultural Change in Northeast Thailand

Conceptualizing environmental problems as sustainability problems contributing to local and global environmental change requires an understanding of how societies cope with their natural environment. Indicators for society–nature interactions are fairly well developed for national-level analyses. This study adapts some of these indicators to the local level and relates them to a qualitative assessment of economic and cultural change in a single community. Indicators are derived from material and energy flow accounting methods and address two major objectives: Firstly, to identify mutual influences between the global and the local level. Secondly, to assess future potentials of environmental pressures and impacts that can be expected to occur as such communities follow a path of further modernization. This study of a small rice-farming community in Northeast Thailand deals with physical as well as sociocultural aspects in order to produce a broad picture of society–nature relations. The indicators developed portray a society in the midst of transition and rapid modernization. This becomes apparent when comparing the results to those of similar studies in traditional and industrial societies. What we see is a community struggling to adapt to global influences, while at the same time maintaining subsistence with traditional coping mechanisms.

Operational Eco-efficiency: Comparing Firms' Environmental Investments in Different Domains of Operation

Eco-efficiency has been established as a crucial concept for corporate environmental management. Most approaches deal with eco-efficiency on the level of the company or the product. However, given that companies have special budgets earmarked for environmental operations or investments, the question arises as to which operation within which domain is the most eco-efficient. This article presents an approach to supporting these decisions by calculating eco-efficiency on the operational level. The procedure is demonstrated using a case study of the Swiss National Railway Company. Investments and operations in the domains of energy production, landscape and nature conservation, noise protection, and contaminated soil remediation are assessed and compared. Decision-makers seeking an eco-efficient corporate investment policy will find, in this concept, a guideline for prioritizing various domains of operation as well as the operations within a domain.
