Environmental Justice 2.0: new Latino environmentalism in Los Angeles

This paper presents the results of ethnographic research conducted with several environmental justice (EJ) organisations in Latino communities of Los Angeles, California. Traditional EJ politics revolves around research and advocacy to reduce discriminatory environmental exposures, risks, and impacts. However, I argue that in recent years there has been a qualitative change in EJ politics, characterised by four main elements: (1) a move away from the reaction to urban environmental “bads” (e.g. polluting industries) in the city towards a focus on the production of nature in the city; (2) strategies that are less dependent on the legal, bureaucratic, and technical “regulatory route”; (3) the formation of a distinctive “Latino environmental ethic” that offers a more complex consideration of the place of race in EJ organising; and (4) a spatial organisation of EJ politics that moves away from hyperlocal, vertical organisation towards diversified city-wide networks that include EJ organisations, mainstream environmental groups, nonprofits, foundations, and entrepreneurs. This shift in EJ movement politics is shaped by broader political-economic changes, including the shift from post-Fordist to neoliberal and now green economy models of urban development; the influence of neoliberal multiculturalism in urban politics; and the increasingly prominent role of Latinos in city, state, and national politics. New spaces of Latino EJ also reflect the ambitions of Los Angeles as a global city, with urban growth increasingly framed in an international discourse of sustainability that combines quality of life, environmental, and economic development rationales.     

不完全竞争行业中的环境工具有效性研究:一个理论框架

各级政府贯彻落实绿色发展的理念,实现经济增长与环境保护的共赢,才能真正实现"绿水青山就是金山银山"。在经济"新常态"背景下,防治环境污染是个复杂而系统性的工程,需要进行经济追因与综合治理,其中,制定实施有效的环境政策工具尤为关键。本文把微观经济学中的双寡头产量竞争模型作为基准模型拓展用于环境经济分析,并把环境税、环境规制、排污权交易这三类主要环境工具对企业生产决策的影响纳入基准模型,旨在对比研究不完全竞争行业中环境工具的有效性问题。结果表明:主要基于市场机制的环境经济政策比行政色彩浓厚的环境规制更有效率。提高环境税率或排污权价格均能显著削减行业污染物排放量,如果环境税率恰好等于排污权价格,则环境税与排污权交易这两类环境工具的效力相等。这对进一步建立和完善我国尚处于探索或初始实施阶段的环境工具,促进石化、电力、钢铁等不完全竞争行业的主要污染物减排,具有一定参考价值和借鉴意义。     

A radical public administration? Green radicalism and policy influence among local environmental officials in Sweden

Green radicalism among local environmental officials in Sweden is examined with the aims of theoretically elaborating on different dimensions of Green radicalism in the context of public administration, exploring the dimensionality of Green radicalism among officials, and examining the extent to which Green radicalism is associated with policy influence. Three types of Green radicalism are identified: Green ethics, Green institutional change, and Green activism. Survey data (N = 701) show that the three theoretical dimensions are present among officials, and that there is no negative association between radicalism and influence. It is primarily officials with Green activism beliefs who perceive themselves as able to influence policy. These findings suggest a need for more nuanced understanding of and further studies into the role of public administration in the quest for more radical Green reforms.     

Welfare states and environmental states: a comparative analysis

A framework is presented for thinking about state intervention in developed capitalist economies in two domains: social policy and environmental policy (and, within that, climate-change policy). Five drivers of welfare state development are identified, the ‘five Is’ of Industrialisation: Interests, Institutions, Ideas/Ideologies, and International Influences. Research applying this framework to the postwar development of welfare states in the OECD is summarised, distinguishing two periods: up to 1980, and from 1980 to 2008. How far this framework can contribute to understanding the rise and differential patterns of environmental governance and intervention across advanced capitalist states since 1970 is explored, before briefly comparing and contrasting the determinants of welfare states and environmental states, identifying common drivers in both domains and regime-specific drivers in each. The same framework is then applied to developments since 2008 and into the near future, sketching two potential configurations and speculating on the conditions for closer, more integrated ‘eco-welfare states’.     

Simulative governance: on the collaborative narrative of civil society participation in the CDM stakeholder framework

The Kyoto Protocol’s Clean Development Mechanism (CDM) is often cited as an exemplar of new, hybrid forms of global environmental governance operating at the public–private interface. Practically, enacting this arrangement involves a wide range of non-state actors. This broad involvement is here assumed to mark a shift towards more polycentric and networked modes of governance in which agents collaborate as ‘stakeholders’ in the process of consensual rule-setting and implementation. Using post-political critique, the depoliticising effects of the stakeholder framework on civil society actors are interrogated, using formal and informal participation opportunities to raise concerns regarding specific CDM projects. The analysis suggests that the CDM’s collaborative narrative of stakeholding structurally fails to stimulate public (re)engagement and is, instead, a prime example of simulative governance that struggles to achieve the simultaneity of two incompatibilities: the participatory revolution and the post-political turn.     

环境分权、市场分割与碳排放

中国有着庞大的环境管理队伍以及巨大的国内市场,科学的环境管理制度以及高度一体化的国内市场将深刻改变碳排放格局,然而,已有研究对于这些影响碳排放的体制性因素既缺乏足够的理论分析也缺乏实证检验。有鉴于此,本文首先分析了环境分权和市场分割影响碳排放的理论机理,并提出了三个理论假设,进一步地,本文以环境管理人员在不同层级政府的配置衡量环境分权度,以相对价格法衡量市场分割程度,基于1995-2012年的省际面板数据,从实证层面检验了环境分权和市场分割对碳排放的影响效应。结果显示:环境分权和市场分割都显著地加剧了碳排放,原因在于分权的环境管理体制安排扭曲了激励,无法对碳排放形成真实有效的约束,而市场分割则恶化了碳排放在区域间的配置效率。同时,环境分权与市场分割对碳排放的共同影响作用上存在互补效应,即环境分权程度越高,市场分割对碳排放的负面影响效应越大,反之,市场分割程度越高,环境分权对碳排放的负面影响效应也越大。这主要是由于环境分权与市场分割是地方政府一对互补的策略行为,在环境分权较高的地区,地方政府进行市场分割的能力越强,而在市场分割较高的地区,地方政府争取环境事务管理权的动力越强。因此,在既定的碳排放约束下,中央政府一方面需要适度集中环境事务管理权限,进一步优化环境事务管理机构设置以及人员队伍在不同层级政府间的配置,提高对碳排放的管控效率,另一方面需要打通省际壁垒,加快区域市场一体化建设,优化碳排放的区域配置,提高碳排放效率。     

双重外部性约束下中国资源型企业绩效研究

中国资源型产业的可持续发展受到代际外部性与环境外部性的双重制约,却长期存在过度进入导致的过度开采,加剧了资源型企业的产能过剩与配置扭曲,但与此相关的"结构-行为-绩效"关系研究尚未将外部性纳入考量。本文引入双重外部性,构建了"SCP-2E"模型,并基于80家资源开采上市公司2011-2014年的面板数据,首先运用使用者成本法和条件估值法分别估算了代际外部性和环境外部性,然后将它们作为企业行为的因变量和影响绩效的自变量分别纳入资源型企业的SCP-2E模型中,同时考虑双重外部性下市场结构、所有权性质等因素对绩效的影响。结果发现,中国资源型产业有着明显的周期性特征,而2011年以来资源型企业的兼并重组只是单纯扩大了企业规模,而没有切实提高企业效率;进一步结合企业规模和所有权性质的相关性来看,大型企业多以国有企业为主,由此说明企业规模扩大、绩效却显著降低的原因在很大程度是由于国有企业的低效率造成的;另外,目前企业绩效的提高,主要还是依赖于地区经济增长的拉动,但在用电量增速较快的地区,也伴随着较大的环境外部性损失,暂时没有受到资源枯竭的约束。基于以上结论,本文认为,监管部门应加强资源开采权的审查,提高资源型企业的进入门槛和技术标准,适当鼓励企业在不增加生产投资和规模的前提下,通过技术进步和劳动效率的提高提升绩效,而国有企业改革力度重点应放在解决大型国企的低效率问题上。政府应该权衡经济增长与代际和环境负外部性,在保证能源、资源安全的前提下,鼓励和扩大可耗竭资源的进口,逐步建立国家和企业的战略资源储备制度。     

The Many Modalities of Social Networking: The Role of Twitter in Greens Politics

The popular microblogging service, Twitter, contains a variety of potential orientations—interpersonal, broadcast, news, advertising, public service, political, and so on—in its operation and applications. As an evolving social media platform, specificity and context are essential in understanding its significance and use-value. This paper investigates the multiple modalities of Twitter in the context of formal politics and, in particular, the Greens party in Australia. Presenting original evidence drawn from the Greens Members of Parliament and their advisers, it is shown how Twitter is mobilized in response to particular news agendas and stories, unfolding political events and processes, and an ongoing need for the Greens to speak simultaneously to committed environmentalists and the broader electorate. These uses reveal that Twitter is an important addition to the “media ecology mix” in the conduct of environmental politics, playing a direct role in political communication, strategies, and actions.     

城市生活垃圾处理方式生命周期评价的比较研究

生命周期评价理论与方法作为一种量化环境影响的工具,在诸多领域中得到了广泛的应用。在垃圾处理领域,生命周期评价最早在20世纪90年代得到应用。生命周期评价与城市生活垃圾处理的有效结合,将促进城市生活垃圾的减量化、资源化、无害化目标的实现。总结了生命周期评价理论与方法在城市生活垃圾处理中的应用现状。对国内不同城市生活垃圾处理方式环境影响因子进行比较分析,诸如全球变暖潜力、酸化潜力和富营养化潜力等因子。针对其目标范围定义、数据收集、评价方法的选择、结果解释及工艺改进等方面指出了目前研究的局限性和不足。并对未来城市生活垃圾处理生命周期评价的发展方向进行展望。
