我国能源节约战略研究

节约能源，保护环境，是全面建设小康社会、实现可持续发展的必不可少的前提条件。中国万美元GDP能耗水平是发达国家的3至11倍。节能潜力很大。其中工业部门是我国的能源消费大户。其能源消费占全国能源消费总量的比重一直保持在70％左右，其节能潜力也居第一位。2020年中国实现全面建设小康社会的目标．人均GDP是3000美元，按届时人口15亿计算，全国GDP为49500亿美元，所需要的能源总量是33亿t标准煤，万美元GDP的能耗是6．67吨标煤；人均能耗是2．13吨标煤。只要政策选择适当。我国完全可以以当初发达国家一半的能源供应实现其相应的人均经济发展目标。为此，我们需要继续建立和完善适应市场经济要求的推动能源节约与资源综合利用的新机制；加快制定与《节约能源法》配套法规，引导和规范用能行为；加快建立以企业为主体的技术创新体系。     

中国能耗动态增长机理和节能内涵探讨

近年来,尽管我国政府围绕一些阶段性的能源效率改进指标(例如:降低我国单位国内生产总值的能源消耗)实施了一系列政策措施,并且就此已经取得了显著的成效,但这并未从根本上消除我国当前经济社会发展过程中存在的能源浪费和不合理使用现象,以及从长远来看我国经济社会发展趋向和依赖高能耗经济社会发展路径的隐患。究其原因,关键是对符合我国现实国情的节能内涵欠缺充分的认识,从而难以制定具有前瞻性和全局性的节能发展战略。在此背景下,本文在辨析节能基本概念的基础上,结合对我国当前能源消耗动态增长特征及其形成机理的剖析,进一步归纳出我国节能的本质内涵,指出"动态节能"是我国节能的本质内涵,而我国"动态节能"的根本目的在于减少我国实现现代化(例如城镇化和工业化等)整体过程中的"集总能源消耗"。本文开展的以上定性分析工作加深了对我国节能内涵的认识,为相关决策者制定更加全面的节能政策提供必要的决策参考依据。     

Research on Energy Consumption Evaluation Combined with Endogenous Pollutants of China Based on Entropy-Topsis

The traditional evaluation of energy consumption mostly introduces pollutants as a negative economic output into evaluating model,ignoring the configuration relationship among the energy input,pollutants as well as economic output.This paper considers the overall process of energy consumption and constructs an evaluation indication system of energy consumption level combined with endogenous pollutants based on entropytopsis method,then makes empirical research.The results show that China’s energy consumption level presents a fluctuant rise in the premise of emission.Energy consumption level depends on the relationship among energy input,pollutants and economic output.The raise of energy consumption level should not increase economic output and reduce pollutant emission at the expense of environment.Finally,the whole paper puts forward the countermeasures to improve the overall level of energy consumption.     

Research on Energy Consumption Evaluation Combined with Endogenous Pollutants of China Based on Entropy-Topsis

Abstract

The traditional evaluation of energy consumption mostly introduces pollutants as a negative economic output into evaluating model, ignoring the configuration relationship among the energy input, pollutants as well as economic output. This paper considers the overall process of energy consumption and constructs an evaluation indication system of energy consumption level combined with endogenous pollutants based on entropytopsis method, then makes empirical research. The results show that China’s energy consumption level presents a fluctuant rise in the premise of emission. Energy consumption level depends on the relationship among energy input, pollutants and economic output. The raise of energy consumption level should not increase economic output and reduce pollutant emission at the expense of environment. Finally, the whole paper puts forward the countermeasures to improve the overall level of energy consumption.     

能源价格变动对中国节能降耗的影响效应

在分析我国能源比价扭曲对能耗强度影响效应的基础上,建立了Bayesian时变动态回归模型,测算了能源价格变动对能耗的影响效果及变动趋势。主要结论为:①能源比价关系的调整比单种能源价格的国际接轨更为重要。相比国际市场的能源比价结构,中国能源商品价格结构的扭曲度提高了中国的能耗强度,促进了第二产业的增长。②能源价格的变动对单位GDP能耗的影响效应具有显著的时变特征。在电力、煤炭、石油三种能源中,电力价格的变动对能耗强度的影响最大。电力价格变化对单位GDP能耗的影响边际效应在逐年下降,但节能的效果仍很显著。煤电价格联动制约及"从量计征"的资源税偏低使得煤炭价格的上涨反而加大了能耗强度,且1996年以来煤炭价格的提高对单位GDP能耗上升的影响效应还在不断加强,原油价格的提高对单位GDP能耗的影响在不同的时间段有不同的作用,但相对煤炭及电力价格来说,石油价格的影响效应最小。2002年以前石油价格的上升对能耗的上升起助推作用,2003年后石油价格的上升对能耗的上升起降低作用且强度逐年加大。     

Reconstituting “America”: The Clean Energy Economy Ventriloquized

With the foregrounding of “clean energy” policies by climate change concerns, the rhetorical constitution of “America” as a collective subject, mobilized to adopt the clean energy economy (CEE), becomes crucial. Here, I analyze the constitutive rhetoric of Pew Charitable Trusts’ landmark 2009 report on the CEE, drawing from the ventriloqual perspective to communication. I argue that this approach provides a more pragmatic, conversational understanding of the interpellative process constituting “America,” noting it to be hybridized and composed of various human and nonhuman agents. Tracing the ingoing interaction among agents—some manifest in the text, others spectral—sheds light on the complex relations of power at stake, recognizes the open-ended possibilities (and restrictions) of agency, and the role of material structures shaping environmental communication and policy.     

中国工业化进程与能源矿产供需均衡的研究

工业化与能源需求的均衡关系及解决工业化进程中能源供需失衡的战略途径是中国工业化进程中需要探讨的重大问题.文章运用协整技术,就1990-2008年间中国工业化进程与能源需求协整关系的检验,认为中国工业化与能源需求增长具有长期稳定的均衡关系,能源需求将继续保持增长,能源利用效率也将持续提高.然而工业化进程中重工业化高能耗结构特征与能源低效利用并存的困境以及能源供需矛盾不利于能源供需平衡的平稳发展.我国应适应工业化进程的基本规律,转变能源消费方式;走新型工业化道路,适当限制低附加值产业发展,鼓励产业向离附加值、低能耗、高技术产业转移;在实现能源开发利用技术进步和创新的同时.有效利用国内外能源资源;建立能源应急机制等战略途径来实现工业化进程中能源供需平衡发展.     

Visitor Proficiency Profiling and Risk Communication at a National Park

While cognitive heuristics may produce successful, efficient outcomes, they can also introduce predictable biases that may be unavoidable even for seasoned experts. This study connects the concept of “professional intuition” to the practice of strategic communication, suggesting that people may rely on heuristics to profile an audience. These judgments, in turn, influence crafting of communication to meet the audiences’ assumed needs, the defining element of an audience-centered approach. Using interview and observational data, this study examines how national park staff use heuristic cues to evaluate visitors during face-to-face interactions. The assessments employees make, in turn, influence whether they encourage or discourage visitors from participating in inherently risky recreational activities. This visitor proficiency profiling, together with the strategic communication strategies employed, extends audience-centered communication to include both informal messages as well as individuals not necessarily trained as risk communicators. Both applied and theoretical implications of this research are considered.     

China’s Export Expansion, Export Structure and Energy Consumption

Since the reform and opening up,China’s export trade has maintained a rapid growth;meanwhile,China’s energy consumption has been increasing sharply. "High export and high energy consumption" has become the feature of China’s trade and economic development.In this paper,based on the input-output analysis approach,the authors have conducted an empirical study on the export trade and energy consumption of 21 trade industrial sectors.The results show that,China is a big net exporter of embodied energy.Assuming that the export growth rate of embodied energy maintains to be about 23.6%,the average annual growth rate of the past 32 years,and based on the input-output data of 2005,by 2030 China’s net export of embodied energy would be over eight times more than the aggregate energy production,which is obviously infeasible.As a country of very low per capita energy,China must change its export pattern,encourage or restrain the export of different industrial sectors according to their energy consumption intensity,and promote structural change of energy-efficient exported products,so as to achieve the sustainable development.Accordingly,the authors put forward some suggestions.

节能是提高能效、减少污染、实现能源可持续消费的有效手段。本文以山东省济南市居民节能措施选择的实地调查数据为基础．运用联合分析方法对其所涉及的节能项目、途径、成本和效果诸方面的偏好程度如何影响节能措施的最终选择进行了实证分析．结果显示：居民在进行节能活动时，首要考虑的是节能措施的效果。其次是节能成本和项目。而对节能实现途径不太关注；居民更偏好效果明显、成本低的节能措施；倾向于简单、初级的行为节能方式（改变用能习惯）；在技术节能方式中。更倾向通过购买能效用具而非改造原来用具实现节能。同时．本文对于不同特征家庭能源消费者选择节能措施的偏好差异也进行了分析。从而为政府推进全社会节能提供决策指导。     

Energy Embodied in Goods in International Trade of China: Calculation and Policy Implications

Abstract

In recent years, China’s energy demand and Greenhouse gas (GHG) emissions have grown very fast, quite an amount of which was exported as energy embodied in goods in international trade rather than consumed domestically. Starting from the concept of embodied energy, based on input-output energy analysis approach, in this paper the energy embodied in goods in international trade of China during the period from 2001 to 2006 is calculated. The results show that although China has become a net importer of petroleum since 1993, China is a net exporter of embodied energy due to international trade in goods. In 2002, the total amount of energy embodied in exported goods was about 410 million tce (ton of coal equivalent, hereinafter referred to as “tce”). Eliminating the amount of energy embodied in imported goods of about 170 million tce, the net export of embodied energy was about 240 million tce, accounting for 16% of the aggregate primary energy consumption of that very year in China, and the net export of embodied emissions was about 150 million tons of carbon. With the rapid growth of China’s international trade, assuming no structural input-output changes of among sectors, in 2006 the net export of embodied energy went up to about 630 million tce, an increase of 162 % over 2002. In addition, this paper also analyzes the possible sources of error in calculation, and also discusses the policy implications according to the result of the calculation.     

Analysis of Influences between the Energy Structure Change and Energy Intensity in China

In this article, based on the data of the energy statistics from 1980 to 2004, we analyze the relationship between the primary energy structures, technique, management, and the energy use per unit of GDP based on the path analysis approach and present the degree of the direct, indirect, and the overall influences of the primary energy structures on the energy use per unit of GDP. The results show that the technical change and management level play a decisive role in the energy use per unit of GDP, and the ratio of oil consumption was the major limiting factor to energy use per unit of GDP. We then found the model of the energy use per unit of GDP and the structures of the primary energy consumption, eliminated the multicollinearity in the model with the path analysis result, and finally, analyzed the influence of the primary energy structure on the energy conservation.     

小城镇能源优化配置研究

构建我国能源安全体系面临诸多困境。小城镇能源保障是其最薄弱的环节之一。但小城镇能源保障及其优化配置问题并没有得到政府、学术界应有的重视。通过与城市的比较分析。得出小城镇能源类型和结构特征，指出能源自然禀赋构成小城镇能源类型和结构的“本底”。社会经济发展水平。产业结构变迁主宰小城镇能源类型和结构变迁。在此基础上，提出了小城镇能源优化配置战略目标和导向。根据这一目标和导向，对小城镇能源优化配置的政策措施进行初步探讨。包括编制小城镇能源资源利用规划；加快可再生能源的应用技术研究；建立小城镇能源资源分配、开发、流通的市场机制；保护小城镇能源资源；优化小城镇产业结构。大力推动循环经济；推广分布式能源供给模式，提高小城镇能源供给安全。     

GDP与能源消费之间的关系研究

选取中国1985-2009年能源消费总量与GDP的年度数据作为研究样本,运用Eviews对时间序列的GDP和能源消费总量进行单位根检验、协整检验、Engle-Grange因果关系检验.结果发现,GDP、能源消费总量的二阶差分在5%的显著性水平下是平稳的;GDP、能源消费总量在5%的显著性水平下,存在协整关系;Engle-Grange因果检验结果显示,在5%的显著性水平下,GDP与能源消费的因果影响关系不明显,但长期能源消费对GDP存在单向因果关系.从研究的结论来看,GDP增长引起能源需求和消费内生性的增长,减少能源的消费不影响产出、就业、收入的增长.要解决我国目前经济发展过程中诸多矛盾,使经济持续发展,首先,必须积极开发新能源、提高能源利用效率、调整能源战略、实施能源保护和节能政策来弥补我国能源短缺,提供充足的能源供给作为保障.其次,要转变经济增长方式、调整产业结构,尤其是工业结构;加快技术创新、发展高新技术产业和知识密集型产业,使我国经济发展摆脱对能源的依赖.     

能源消费与环境污染的边限协整分析

能源的使用是导致环境恶化的主要原因之一,所以研究能源消费与不同污染物之间的关系就很有必要。本文以1985-2007年的年度数据为样本,建立了自回归分布滞后—误差修正模型,并运用边限检验对我国的能源消费与环境污染之间的关系进行了实证研究。研究结果表明:长期来看能源消费总量、煤炭占能源消费总量的比重和水电、核电、风电占能源消费总量的比重对SO2的排放有重要影响,但是对工业烟尘排放量来说只有水电、核电、风电占能源消费总量的比重的影响是显著的;短期来看煤炭占能源消费总量的比重对SO2排放的影响是显著的,能源消费总量和水电、核电、风电占能源消费总量的比重对工业烟尘的排放有显著影响。由于能源消费总量和结构对不同污染物的长期和短期影响存在较大差异,所以在治理时应区别对待。     

Energy revolution:for a sustainable future

The discovery and use of fossil fuels have not only helped the evolution of human society from agricultural civilization to industrial civilization,but also caused serious environmental and climate problems.The earth is calling for a sustainable future,and a change from industrial civilization to ecological civilization based on the new"energy revolution".A macroscopic quantitative analysis of China’s environmental capacity and climate capacity shows that China is in urgent need of changing the extensive developing mode and having an energy revolution.It is foreseeable that fossil fuels will remain the most consumed source of energies in China now and in the next few decades.Although the efficient and clean use of fossil fuels are very important,this is not an energy revolution or the fundamental solution to environmental and climate problems.Unconventional gases including shale gas play an important role in the mitigation of environmental problems and climate change,but"shale gas revolution"or"shale gas era"is not suitable to China since the proportion of natural gas in primary energy structure in China can only be increased by a maximum of 20%.The transition of Chinese energy structure from fossil-fuels-dominating stage to multiple-energy-sources stage and then to a nonfossil-fuels-dominating stage is the inevitable future,with the help of great contribution from renewable energy and nuclear energy.Among renewable energies,the proportion of non-hydro renewable energies will gradually increase.Improvement of their market competitiveness(economic efficiency)relies on technological innovation.Renewable energies will be the main energy source for the earth in future.Despite the impact of the Fukushima nuclear disaster,the whole world,including China,will not give up nuclear energy development.Safe,steady,and large-scale development of nuclear power is a rational choice of China.Transition from nuclear fission power plant to nuclear fusion power plant is the inevitable future.Nuclear energy will be a sustainable energy source and another main energy source of the earth in future.China needs to enhance energy security consciousness,promote energy saving,and change the energy supply-demand patterns,that is the transition from"meet a too-fast-growing demand with an extensive supply"to"meet a reasonable demand with a rational supply".All countries need to work together to address global environmental problems and climate change.Energy revolution is the foundation for a sustainable future.With a wide range of international cooperation,the win-win cooperation is the only way of overcoming these challenges.
