中国地区间跨界污染治理的两阶段多边补偿机制研究

近年来,以雾霾、河流污染等为代表的跨界污染问题严重影响了我国经济社会的可持续协调发展。本文将跨界污染治理视为典型的地区间外溢性公共品,从公共经济学的视角出发,分析了我国地区间跨界污染治理的种种困境,并通过构建两阶段多边博弈模型,探讨了补偿机制的可行性。本文首先构建了一个跨地区的污染模型,通过中央政府干预或不干预的博弈分析发现,当污染存在地区内部及跨地区的外溢性时,如果中央政府不介入而由企业自行设定产出水平,那么企业的污染排放水平将超过社会有效率的水平。在此基础上,本文进一步构建了一个两阶段多边补偿机制博弈模型,即由中央政府设计一个地区内部企业与居民之间以及跨地区之间的补偿机制,来解决以上的无效性问题。结果显示,当企业支付的补偿金额取决于居民设定的补偿系数,而居民得到的补偿金额又取决于企业设定的补偿系数时,相互影响的博弈关系使得企业和居民从自身的利益出发,将补偿系数设定在企业污染对于居民边际损害的水平,从而企业生产水平会达到有效状态,两阶段多边补偿机制实现了有效的污染排放。本文在庇古税思想的基础上,通过放松庇古税对外部性相关信息的强假设,构建了一个两阶段多边补偿机制,即由企业缴纳庇古税后,中央将征收的庇古税补偿给居民,这样不仅内部化了企业污染给居民造成的负外部性,还进一步平衡了地区间的跨界污染治理问题。     

The relationship between country and individual household wealth and climate change concern: the mediating role of control

The relationship between wealth and climate change concern has been a focus of several studies. In this article, we hypothesize that richer households (and countries) are less concerned about climate change because wealth provides a buffer against some of the related risks. This leads people in wealthier countries and households to perceive a greater sense of control over climate change impacts, which in turn results in lower levels of concern. We tested this hypothesis using a unique household survey encompassing 11 OECD countries and over 10,000 households and applying mixed multi-level regression models. Our results confirmed a statistically significant negative relationship between country and household wealth and individuals’ perceptions of the seriousness of climate change. This study contributes to current literature by showing that this relationship is mediated through sense of control, measured at the country level by the country’s readiness index and at the individual household level by the extent of adoption of energy efficiency improvements. These findings raise the question of how best to incentivize action on climate change amongst those with the ability—but not necessarily the motivation—to respond.

     

政府环境规制下的企业治理动机与公众参与外部性研究

本文构建了多主体参与环境治理的动态一般均衡模型,进行了政府环境规制下的企业内生治理动机研究与公众参与外部性的分析,模拟结果显示,企业内生治理动机、社会福利等不同目标下对应的最优环境税率存在明显差异。随着政府环境税率的不断上升,企业环境技术研发投入会先上升后下降,当环境研发投入水平达到最大时,政府所征收的环境税完全激发了企业的内生治理动机。在环境税率提高的初期,研发引致的环境技术进步使得企业的全要素生产率得以提高,经济产出不断增加,社会福利水平得到增进。当环境税率上升到一定数值之后,环境税带来的资源配置扭曲效应高于环境负外部性的改善效应,对于经济而言,环境税成为扭曲性税收,并会降低社会福利水平。因此,应在保证经济增长和社会福利增进的同时有效激励企业内在治理动机,将环境税率设定在适当水平。本文还模拟了政府与公众参与的组合对于社会福利的影响情况,与仅考虑政府环境规制政策的情形相对比,政府征收环境税和社会组织参与的共同作用可以使得社会福利提高,充分表明了公众参与环境治理存在着正外部性。环境社会组织在一定程度上可以降低政府信息不对称等因素,改善环境治理状况。环境组织的参与还能够使得环境税所带来的环境治理改善和生产效率提高的双重红利逐渐释放。因此,在发挥政府规制与市场调节功能的同时,充分发挥环境社会组织和公众在环境治理中的作用,是改善环境质量、提高公众福利的重要方式。     

适应气候变化的认知与政策评价

气候变化已成为不争的事实.减缓和适应是人类应对气候变化的两类主要措施,在气候变化减缓行动难以很快奏效的情形下,采取具有针对性的适应战略已经成为世界各国更为紧迫的选择.一个有效的适应行动机制需要全社会的广泛参与,而公众和决策层对气候变化的认知是适应行动机制的形成基础.本文以银川阅海湿地适应气候变化能力建设为研究案例,从政府部门和社会公众两个层次进行讨论,比较其对气候变化的认知程度及其对适应措施的评价和需求,以期对适应气候变化策略的认知基础研究提供依据.研究结果表明,无论社会公众和决策层,适应气候变化的意识基础均已基本形成,但公众的认知基础要弱于决策层,并且在认知的准确程度上低于决策层;公众和决策层对气候变化适应政策的实施都做出了正面的评价,但决策层的评价普遍显著高于公众;对于适应政策的需求,公众的政策需求主要集中在公共服务方面,而决策层的适应策略是多方位的,也包括通过限制个人行为来获得公共利益.     

气候变化经济学研究综述

对近10 a来国内外有关气候变化经济学研究成果作了综述。气候变化经济学是一门研究人类干预气候变化过程中涉及经济过程的学科。当前的研究热点包括气候变化的经济影响、适应措施的成本和收益、国际合作机制和涉及代际公平的折现率选取。 在研究方法上,对得到广泛运用的成本收益分析法和碳税机制作了详细的评述。在应用层面上,欧美发达国家在城市气候变化经济评估系统建立和碳税征收方面都有成功的应用,但我国在这方面的实践还处于起步阶段。对于我国气候变化经济学领域的研究来说,比较适合在发达省份以市域或省域为单位开展成本收益评估,发展中省份则应将更多关注放在评估气候变化可能造成的经济损害及相应的防范措施。此外,我国也应关注在欧盟地区实施较为成功的碳税政策,虽然目前在中国开征碳税的可能性较低,但是对碳税在中国实施的可行性、税率选取及立法保障机制等方面的探讨和研究仍是必要的     

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.     

New Development in Study of the Faustmann Optimal Forest Harvesting

Abstract

Chinese forest resources have become very scarce in the face of rapid economic growth demand, while the reform of collective forest right system is in full swing across the country. It will directly affect the regeneration level of forest resources and the diverse ecological value functions. In this article, the mainstream model paradigm of forest economics, that is, the basic framework of the Faustmann model and its evolution process are made in a more detailed explanation, especially the extended model including considered silvicultural effort, tax subsidies, risk dynamic management, and forest regeneration factors are made in more detailed explanations. This article concludes with the future further research directions of forest economics, including the design of dynamic models that includes considered uneven-aged forest management, non-timber goods and services, dynamic forest models. The research reflects the general trend of interdisciplinary and cross-border.     

论政府能力与可持续发展

基于ILBM的太湖饮用水源地管理研究——以苏州市为例

饮用水源地管理是全球关注的热点,安全的饮用水源供给依赖于不断完善的管理机制,湖泊流域综合管理(ILBM)可以为水源地管理的完善提供很好的框架。湖泊流域综合管理框架由管理组织、政策、公众参与、信息、科学技术和资金六要素构成。基于该框架,文章对苏州太湖水源地管理现状进行了分析和诊断。研究发现,苏州市太湖水源地管理存在缺乏有效的管理组织协调机制、缺乏经济激励型和教育与公众参与政策、公众参与水平低、信息可信赖度差、科学技术与地方需求结合不紧密、资金投入不稳定等问题。基于ILBM管理框架,提出了水源地管理优化的政策建议。     

Exploring the Adaptation-mitigation Relationship: Does Information on the Costs of Adapting to Climate Change Influence Support for Mitigation?

Can information about adaptation costs influence citizens’ willingness to support climate change mitigation? Some scholars are concerned that policy discussions on adaptation might present climate change as a more manageable problem, and therefore crowd out mitigation efforts. On the other hand, providing information on adaptation costs may sensitize citizens to these costs, thereby increasing their willingness to support mitigation. To assess these conflicting predictions, we fielded a web-based survey experiment using a sample of 2,000 US-based respondents. We presented the respondents with a hypothetical newspaper article regarding a proposed gasoline tax (a mitigation strategy) and measured the support for this proposal across different treatment groups. In the control group, the respondents were told that failure to mitigate climate change could result in a potentially catastrophic outcome, whereas in each of the treatment groups the respondents were provided with information concerning possible adaptation costs. The respondents were then asked about their willingness to support a gasoline tax. Our key finding is that the provision of information about adaptation costs leads to a small increase in the respondents’ willingness to support mitigation efforts. Furthermore, we find that this effect becomes larger when the information regarding adaptation costs is made more specific.     

排污税能够提高环境质量吗

排污收费制度是我国主要的环境政策工具之一。然而,自1982年这一制度正式建立实施以来,经过2003年的制度改良,始终未能解决征收成本高、使用效率低、寻租行为盛行的问题,这一系列的问题导致该制度的减排效果不佳。因此,近年来,排污费改排污税的改革提上议事日程。这一改革是否能够收到设计者们预期的效果?为从理论上回答这些问题,从中国现实出发,借鉴环境库兹涅茨曲线的研究方法,通过设计一个包含政府征收排污税行为和政府污染治理技术投资行为的经济系统,考察动态条件下排污税对环境质量的长期影响,以及征收排污税对厂商行为和消费者行为的长期影响。根据本文的分析,单一的征收排污税并不一定能够改善环境质量,不一定能够促进环境库兹涅茨曲线拐点的出现,也不能减少企业污染物排放;同时,排污税降低了资本积累速度和经济增长速度,但对消费者消费路径的影响是不明确的。最后,本文建议,政府应投资于污染治理技术的改进能够持续的减少最终污染物排放,达到改善环境质量的目的。     

Elites, climate change and agency in a developing society: the Chilean case

Faced with global climate change, local elites are confronted with the main dilemma of a developing country: development requires economic growth, but this effort also requires consideration of environmental factors and sustainable patterns of production and consumption. Based on empirical evidence from qualitative research on businesses and political elites in Chile—a paradigmatic South American middle-income country—this paper explores the extent to which local elites are aware of the severity of challenges posed by global climate change and identify main climate change concerns in their discourse. The degree to which domestic elites are aware of the paradigm shift they must assume toward clean industrial production is a key issue of environmental governance that involves private non-governmental actors. This paper gives clues to a better understanding of what is happening with strategic actors in developing nations and their understanding of their decision-making capacity concerning environmental policy and investments for facing global climate change. The main conclusion of the research is that awareness of climate change in local elites’ discourse is relative. It is not accompanied by a full acceptance of their agency and is not leading to a paradigm shift toward a clean model of development because of domestic elites’ position within globalization processes.     

The Voice of Science on Climate Change in the Mainstream Turkish Press

This study aims to explore how the Turkish press represents the discourse of climate change scientists. This is achieved by analyzing climate change-related articles that quote scientists, directly and indirectly, in two Turkish mainstream newspapers (N = 132, 7 years). The Turkish case illustrates how scientific rhetoric is used for presenting climate change as a matter of concern in an industrializing country. The analysis suggests that climate science is portrayed as an un-discussed authority. News articles rely on data about the disturbance of species and the state of the natural environment to provide proof of global warming, by which they produce an implicit moral imperative. The articles also portray the worst threats and challenges—those pertaining to human society—as residing mostly in the future. We conclude by discussing the implications of the use of a projected future to convey a discourse emphasizing the alarming risks associated with climate change.     

对当前全球气候变化问题的思考

全球气候变化问题已经超越了一般环境问题的范畴,而成为国际政治经济外交关系的重要考虑因素。随着《京都议定书》的实施以及气候变化问题谈判进程的加快．对我国未来经济社会发展提出了挑战。文章分析认为．要求主要发展中国家承诺减限排义务的压力与日俱增,而我国开始进入工业化中期．应对气候变化问题的能力还比较薄弱。因此．提出应对全球气候变化问题的一些思考：（1）充分认识全球气候变化问题的重要性和严峻性,准确把握国际谈判进程;（2）加快制定适应和减缓气候变化的国家战略。采取适合我国国情的有力措施积极应对气候变暖;（3）加强气候变化领域的能力建设．提高我国参与全球气候变化活动的能力;（4）充分利用国际合作机制,提高我国应对气候变化的技术水平与经济能力。     

中国水资源管理博弈特征分析

随着中国水资源匮乏和水污染态势日益严峻．建立一个面向效率和公平的水资源管理机制的需求日益凸现。本文在比较传统行政模式和市场模式下水权管理不同特征的基础上,分别从静态和动态两个角度．从水量和水质两个维度分析了两种模式下的水用户博弈特征。结果表明：政府管制会出现“政府失灵”。无法实现政府和水用户之间的激励相容;在完全市场机制配置情况下,由于个人和集体理性的不一致,会导致水资源被过度污染、治污的公共产品提供不足等“市场失灵”,基于不同模式下各自的利与弊,无论哪一种单纯的管理模式都不能满足水资源的可持续发展要求。认为中国水资源管理需要把水量和水质、政府管制与市场机制两种配置方式的优势相结合,提出了一种准市场水权交易机制分析框架。     

应对气候变化需以生态文明理念构建全球技术合作体系

气候变化是人类发展过程中遇到的最大全球性环境问题,也是最大的外部性问题。IPCC报告显示,实现本世纪末温度升高不超过2度的目标,需要全球经济和能源系统深度的低碳转型,并在本世纪下半叶达到温室气体的净零排放。应对气候变化因此面临着前所未有的技术创新与合作需求。2015年底达成的《巴黎协定》提出了落实技术开发与转让的长期愿景,主张对气候变化领域的技术创新给予政策和资金支持,使发展中国家在技术周期的早期阶段就能够获取必要的技术,从而为实现全球应对气候变化提供保障。然而,基于工业文明的传统技术创新与合作模式难以满足保护全球气候的技术需求。减缓与适应技术是气候变化挑战下全球命运共同体的公共财富。为保证其足够的供应,必须超越追求私人利益最大化的狭隘,基于生态文明理念构建全球应对气候变化的新型技术合作体系。其核心是:实现多赢的合作目标,遵循"生态人"的合作原则,体现协同的合作内容,基于互信的合作形式,鼓励多元主体的参与,促进合作成果的分享。中国作为新兴发展中大国,对应对气候变化技术国际合作有多元的利益需求。为有效落实《巴黎协定》,亟需以加速国际合作为契机,积极谋划中国应对气候变化技术对外合作的总体方略和具体行动,有针对性地制定与发达国家、其他发展中国家及欠发达国家间优势互补的合作计划,探索并引导"南-北-南"三方技术合作等新形式。     

环境税条件下项目可进入与退出期权博弈分析

环境税是解决当前日趋严重的环境与经济发展冲突问题的有效手段之一,研究其如何影响投资者进入与退出项目的竞争策略是更好地制定环境税收政策的前提。与现有文献不同,本文应用期权博弈理论,构建煤电项目双寡头期权博弈模型,分进入和退出两种情况分析项目最优转换策略,并且定量分析环境税税率对最优转换临界值的影响。结果表明:环境税税率与最优转换临界值呈正比关系,即环境税率越低,项目越容易进入,并且更加难以退出;当存在竞争威胁时,投资者会加速进入与退出项目,当环境税强度逐渐变大时,将超过项目相互竞争的影响并起主要作用;在进入情况时存在等待、抢先进入和同时进入均衡,在退出情况时存在不退出、抢先退出和同时退出均衡,最后,分别给出各个均衡条件下环境税政策及影响,为政府制定环境税政策提供一种分析思路。     

自然资源代际转移模型研究

代际均衡发展是可持续发展的核心内容之一，而代际均衡的实现在目前情况下有赖于代际主动财富转移改策实施。政府的宏观调控是实施这一政策的有力手段。具体的措施可开征“资源代际补偿税”以建立专项基金制度     

The social and scientific values that shape national climate scenarios: a comparison of the Netherlands,Switzerland and the UK

This paper seeks to understand why climate information is produced differently from country to country. To do this, we critically examined and compared the social and scientific values that shaped the production of three national climate scenarios in the Netherlands, Switzerland and the UK. A comparative analysis of documentary materials and expert interviews linked to the climate scenarios was performed. Our findings reveal a new typology of use-inspired research in climate science for decision-making: (i) innovators, where the advancement of science is the main objective; (ii) consolidators, where knowledge exchanges and networks are prioritised; and (iii) collaborators, where the needs of users are put first and foremost. These different values over what constitutes ‘good’ science for decision-making are mirrored in the way users were involved in the production process: (i) elicitation, where scientists have privileged decision-making power; (ii) representation, where multiple organisations mediate on behalf of individual users; and (iii) participation, where a multitude of users interact with scientists in an equal partnership. These differences help explain why climate knowledge gains its credibility and legitimacy differently even when the information itself might not be judged as salient and usable. If the push to deliberately co-produce climate knowledge is not sensitive to the national civic epistemology at play in each country, scientist–user interactions may fail to deliver more ‘usable’ climate information.

     

中国资源税改革的政策研究

中国矿产资源税费制度是改革开放后在矿产资源开发利用时,相关经济主体利益分化且相互间进行利益博弈的过程中发展演变而成的,资源税是以资源为对象课征的税种.随着自然资源消耗日益严重,资源税日益成为一个非常重要的税种.本文在对资源税改革的相关文献进行总结的基础上,回顾了我国资源管理的历史沿革,分析了资源税调整的国际经验,同时以煤炭市场为例,应用带有异方差调整的最小二乘法回归的计量经济模型,并分析了我国资源税调整对资源价格的影响;并在此基础上针对我国目前资源税费普遍较低,导致资源市场价格偏低,不利于资源的有效保护和合理利用的现实情况,对资源税税率及征收进行了设计:即根据矿产资源在企业销售收入中的贡献率和矿产资源的性质不同分别按照从价计征、从量计征或特殊计征三种方式进行计征;最后从资源税的征收范围、方式、生态补偿机制、环保退税机制以及加强资源的利用效率等方面提出了我国资源税改革的政策建议.
