企业环境信息公开与政府监管策略的演化博弈分析

由于企业与消费者、投资者、政府等利益相关者之间存在着信息不对称,而真实的企业环境信息是利益相关者做出决策的必要前提,所以具有良好环境行为的企业愿意公开真实的环境信息,但同时也会使不具有良好环境行为的企业有动机公开虚假的环境信息以谋取额外收益,进而导致企业环境信息的信号传递失效。针对此问题,本文考虑了相关主体的有限理性特征,构建了企业是否真实公开环境信息与政府监管行为交互的演化模型,分析了不同参数的变化对系统演化结果的影响,并通过数值实验模拟了不同初始状态和参数设置下的系统演化过程,得出了一定的结论。研究表明:初始状态时的政府监管概率、政府的监管成本、对企业公开虚假环境信息的惩罚、政府选择监管策略的收益、企业真实公开环境信息的收益和企业的伪装效果系数对系统的演化结果具有重要影响,通过政策手段对这些参数进行调控可以引导系统向良好模式演化,使企业公开真实的环境信息,达到环境信息的信号传递作用。     

Investigating supportive conditions for participation in voluntary environmental programs

Voluntary environmental programs (VEPs) are commonly construed as contracts between industry and government that encourage businesses to voluntarily mitigate their environmental impacts beyond legal requirements. This research explores conditions under which polluting firms are likely to participate in VEPs. We analyze 34 comparable VEPs whose shared goal is to reduce greenhouse gases emissions, with focus on the alleged influences of three factors drawn from existing scholarship: government supervision; economic instruments; and public disclosure of participants' environmental records. The statistical results show a greater effect from government supervision than complete voluntarism and the positive effect of financial subsidies on firms' participation in VEPs. Although recent debates over regulatory reform have been oriented towards vesting greater discretion in regulatees to better address environmental harms, the findings imply that even in a highly privatized form of regulation, government oversight and assistance are necessary for promoting this new mode of environmental regulation.     

Clashing coalitions: a discourse analysis of an artificial groundwater recharge project in Finland

The purpose of this paper is to increase understanding of the dynamics of knowledge production in the context of large-scale environmental projects causing local conflict. In particular, the paper analyses the discourse coalitions that formed around an artificial groundwater recharge project for the Turku Region in Finland. The material for this study consists of over 400 articles and opinion pieces which were collected from local and regional newspapers between 1999 and 2010. The articles were analysed by using Hajer's [1995. The politics of environmental discourse. Ecological modernisation and the policy process. Oxford, UK: Clarendon] discursive framework, and the analysis was complemented with the concept of knowledge coalition by Van Buuren and Edelenbos [2004. Conflicting knowledge. Why is joint knowledge production such a problem? Science and Public Policy, 31 (4), 289–299]. Results of the study indicate that knowledge coalitions were formed among the researchers, lay residents, and policy-makers, and they all utilised similar expertise-based factual arguments to support their cause. Thus, the paper participates in the academic discussion on the use and interpretation of expert knowledge in environmental policy-making by reshaping the division between experts and lay residents.     

地方政府竞争与环境规制:基于区域开放的异质性研究

随着全球化推进,各国开始不断消减贸易壁垒,环境规制程度跟着提升,各级地方政府作为环境规制相关政策执行者,国家的环境治理直接受到其环境规制策略影响。论文围绕地方政府恶性竞争导致的环境规制失灵问题,采用变截距GLS方法和Hansen提出的"门槛回归"模型,并利用我国29个省级单位2000-2013年面板数据,将地方政府竞争作为门槛变量,分析在不同门槛值下地方政府竞争、区域开放对工业环境规制的影响,并进一步研究财政收支分权和贸易政策对这种影响是否存在积极或恶化作用,力求从根本上解决地方政府恶性竞争,实现环境有效规制。研究表明:在样本期间内,财政收入分权度较低、财政支出分权度较高、贸易开放度高、金融开放度高和制度环境不完善的地区,地方政府竞争对工业环境规制的促进作用更加凸显。全国和东部地区地方政府竞争对工业环境规制呈边际递减的促进作用,中部地区表现出地方政府竞争对工业环境规制非单调性,西部地区存在对工业环境规制呈边际递减的抑制作用。总之,样本期间内地方政府竞争程度有助于全国和东部地区环境进行有效规制,中部地区跨越门槛值后环境规制失灵,西部地区则存在较严重环境规制失灵问题。为了规避环境规制失灵,我们应提高外商投资的进入环境门槛,地方政府在治理环境时,应削减对自己地区的行政垄断,推动各级地方政府跨区域环境保护合作,并由较高层级的政府来承担环境规制的财政支出责任,不断降低地方政府恶性竞争导致的环境规制失灵。     

为何加速经济增长可以弱化环境污染压力

"增长极限说"认为可以通过降低经济增速来实现自然资源和环境的保护。本文基于特征化事实和实证分析表明,中国经济增长伴随环境污染压力,而在经济阶段性加速增长期间并不必然对环境污染施加更大的压力,相反可以引致环境质量的提高。本文从地方政府机制转变的角度,考察了经济加速增长下的环境污染压力弱化的作用机制。研究结果表明,在经济阶段性加速增长期间,地方制度质量显著提高,地方政府为政治晋升而对经济增长绩效考核压力显著减轻,同时地方税收收入也会显著提高。因此,经济阶段性加速增长期间的这三种作用机制可以使得地方政府把引致经济增长的重点向改善环境方面偏移,从而在短期内显著地缓解经济增长对环境污染的压力。本文的研究结论为众多学者质疑"增长极限说"提供理论和实证依据,随后本文提出了相应的政策建议。     

Sustainability in the USA and New Zealand: explaining and addressing the implementation gap in local government

This paper describes the frustrating reality of sustainability implementation in the USA and New Zealand (NZ), an early adopter of sustainability mandates. Local government has a key role in implementation, but has been slow to uptake sustainable practices. We surveyed senior planners in small to medium-sized local government agencies in both countries to identify which features of local government support (or hinder) sustainability in practice.

Environmentally sustainable practices are not well entrenched in either country. In the USA, the framing of sustainability and public support are significant predictors of implementation. However, sustainability is rarely a priority. In NZ, local government capacity is the main driver of implementation. We recommend that planners promote sustainability values, reconcile economic development goals with sustainability (e.g., green economy model), and translate public support for sustainability into institutional priorities. NZ localities also need increased capacity and US localities need continued Federal and State support.     

政府购买垃圾分类减量促进服务实现路径研究—以广州市荔湾区西村街道为例

实现城市生活垃圾分类减量,是构建循环型社会的首要环节。针对政府中心运作模式与市场运作模式存在的弊端,认为城市生活垃圾管理,可采取政府购买社会组织垃圾分类减量促进服务模式。基于制度经济学理论与垃圾管理实践,重点探讨政府购买服务的相关主体、购买形式与运作过程,明晰社会组织与政府的职责以及确立其运作机制;最后通过广州荔湾区西村街道实践,验证其运作效果。研究表明,该模式是治理城市生活垃圾一种行之有效的模式,对破解"垃圾围城"、开发城市矿山以及推动城市生态文明建设具有重要意义。     

中国低碳城市发展影响因素分析

目前,全国各地都在开展低碳城市建设,但是由于对"低碳城市"认识的不一致,导致了各地建设水平参差不齐。本文根据低碳城市的内涵和特点,识别出19个影响我国低碳城市发展的因素,分别从城市主体水平、发展结构水平和管理水平等角度进行分类说明。通过专家咨询法和建立解释结构模型(ISM),绘制出多级递阶结构图,理顺各因素间的结构关系,阐明了影响因素间内在关联性和层次性。研究结果显示,19个影响因素分为5个层次,其中政府和低碳城市标准位于最高层次,碳排放统计次之,它们是影响我国低碳城市发展的关键因素,并对其余因素产生直接或间接的影响作用。建议现阶段在推进我国低碳城市建设过程中,根据多级递阶结构图所示,采取"自上而下"的模式。当务之急,国家应尽快制定出台《低碳城市标准》,加快开展城市碳排放统计工作,而政府作为城市主体之一,是低碳城市建设的主要推动者和政策供给者,应充分发挥其领导力,使低碳城市建设走上系统化、制度化轨道。     

“后补贴”时代地方政府新能源汽车补贴策略研究

新能源汽车补贴是政府为了发展新能源汽车产业所采取的一项激励政策。现有文献虽在微观层面上研究了政府补贴对新能源汽车推广的影响,但多将补贴政策限定为固定额度的政府补贴,未考虑中国特殊的两级政府补贴政策尤其是地方政府补贴对新能源汽车推广的影响,且在补贴政策的设计上未与新能源汽车的实际推广目标相结合。基于"后补贴"时代的地方政府既要实现新能源汽车推广目标又要保证补贴政策合理退坡的双重现实要求。本文依据当前中央政府为新能源汽车提供固定补贴,地方政府提供配套比例补贴以及制定价格补贴比例上限的现实情形,综合考虑新能源汽车成本、充电桩建设情况、消费者初始效用、中央政府补贴等因素对地方新能源汽车推广的影响,构建了地方政府为实现既定新能源汽车推广目标的最优补贴策略模型。研究表明:(1)对于不同效用水平的消费者,地方政府价格补贴比例上限和配套比例补贴对新能源汽车零售价格所起的作用不同;(2)地方政府补贴政策只有在小于或等于其最优配套比例或价格补贴比例上限时才会对新能源汽车推广产生正向影响。最后,还结合北京新能源汽车推广的实际情况进行了数值模拟,给出了在不同新能源汽车成本、充电桩建设情况、消费者初始效用下北京市政府为实现新能源汽车推广目标的最优补贴策略。数值模拟结果表明,当前北京新能源汽车存在地方配套比例过高、价格补贴比例上限过高等问题。在后补贴时代,北京市政府可依据新能源汽车成本下降、充电设施逐步完善、消费者初始效用提升等因素变化,对补贴进行适当退坡。数值模拟表明,所构造的最优补贴策略模型对后补贴时代地方政府新能源汽车补贴政策的制定具有较高的参考价值。
