行政正当程序视角下环境公众参与制度的规范与完善

行政正当程序理论是环境公众参与制度的理论基础。2014年修订的《中华人民共和国环境保护法》中已经确立以环境公众参与权为核心的环境公众参与制度,但是对于公众参与的规范特别是参与权的规范过于笼统。面对实践中参与主体类型界分不明、多项权利内容规范缺失、法律责任规范效力存疑及环境行政管理规范不足等问题,本文建议应以行政正当程序理论为指导,实现参与主体的类型化界分,细化公众参与权利内容,增加公众参与法律责任条款,并完善环境行政管理公众参与规范。     

Enforcement and price controls in emissions trading

This paper examines how enforcement affects the structure and performance of emissions trading programs with price controls under uncertainty about firms' abatement costs. The analysis highlights how an enforcement strategy can cause abatement-cost risk to be transmitted to enforcement costs via the price of permits. When this occurs, accommodating the effect of abatement-cost risk with an optimal policy results in higher expected emissions and lower expected permit price than their second-best optimal values. However, it is possible to design an enforcement strategy that shields enforcement costs from abatement-cost risk by tying sanctions directly to permit prices. This enforcement strategy stabilizes enforcement effort, the optimal permit supply and price controls are independent of enforcement costs, and the policy produces the second-best optimal outcome.     

郑州市地下水自备井计划用水交易市场设计

根据水权交易市场建设的基本要求,文章设计了郑州市地下水自备井计划用水交易市场,并对相关的水资源管理制度改革提出了建议。郑州市地下水自备井计划用水交易市场首先需要明晰初始水权、实施总量控制和完善监测计量系统;然后建立相应的市场交易制度,包括年度用水计划制定、跨年度用水指标使用、交易产品选择、交易周期选择、交易价格生成和网上在线交易系统建设等。在建立水权交易市场以后,还需要对现有的水资源管理制度进行改革,包括新水权发放、生态与环境影响评价、市场信息公布、现有的用水计划制定和超计划累进加价制度改革等。     

A system dynamics model for evaluating collaborative forest management: a case study in Indonesia

This article presents a system dynamics (SD) method to examine the problem of forest degradation. The model developed takes a system-oriented view of forest management, embracing both social and biophysical factors affecting deforestation. Social factors examined are socio-economic variables or elements that influence behaviour and decision-making choices at the household level. Biophysical factors are four sub-components that are considered major land uses namely, the paddy field component, rattan plantations, coffee plantations and forest stands. The model was applied in a case study located in Pasir District of East Kalimantan, Indonesia. The site covers an area that includes a protected forest and a privately allocated timber license concession. Three village communities are examined in the case study. The SD model developed was applied to the case study focusing on three management policies or scenarios, which are based on access rights to the forest resources within the study area. Specifically, the property arrangements examined in each scenario are: Policy 1 – status quo (i.e. continue present property rights arrangements); Policy 2 – local communities manage the forest exclusively; and Policy 3 – collaborative management involving both local communities and a private company. Results from the model show that the third policy is the most viable option, and also lead to a win–win solution.     

天津市排污权交易评估与分析

在简要介绍天津市排污权交易试点的开展历程与现状的基础上,对天津市排污交易试点进行了评估。分析了排污交易试点过程中存在的主要问题,即排污权交易难以为环境管理服务,其执行状况与实施初衷不完全相符,基础数据的现状尚不支持交易的有效进行,交易跟踪系统尚不健全,初始排污权分配技术方法不成熟。针对以上问题,对＂十二五＂期间天津市排污交易试点开展提出了建议。     

中国实现碳达峰的政策建议——基于碳定价机制模型的多情景模拟分析

碳定价机制是利用市场机制推动碳减排、减缓气候变化方案的核心内容,包括碳排放权交易和碳税等措施。尽管新冠肺炎疫情打乱了经济发展节奏,但是中国主动提高国家自主贡献力度,积极推进战略提升与政策强化。本研究构建并运用"碳定价机制模型"模拟涵盖不同主体范围及政策组合下的碳排放权交易市场运行情况,分析评估碳减排效果及经济影响,为丰富完善我国实现碳达峰的政策工具提供技术支持。     

施用高效氮肥对农田N2O的减排效果及经济效益分析

收集高效氮肥N2O排放资料,利用整合分析法分析高效氮肥对N2O的减排效果.稳定性氮肥排放的N2O是普通肥料的0.66倍,减排效果显著;包膜缓释氮肥N2O排放量为普通氮肥的0.95倍,无显著减排效果.若将全国范围的普通氮肥替换为稳定性氮肥、且用N量不变时,稳定性氮肥在中国农田的N2O减排潜力均值为1.03×108 kgN/a,碳排放交易收入为16.86亿元/a;根据现有市场上稳定性氮肥的价格,每亩地每季补贴4.9元,碳排放交易收入和稳定性氮肥成本增加量相抵.由于稳定性氮肥能有效提高N利用率,保证农作物吸N总量不变时减少用N量,稳定性肥料N利用率提高8个百分点时,N2O减排经济效益(即碳排放交易收入-稳定性氮肥成本增加量)为94亿元/a.     

我国自然遗产保护中的产权问题研究

从经济学角度看,自然遗产保护中必然涉及产权问题,建立合理的自然遗产产权制度是自然遗产保护的关键。我国目前的自然遗产产权制度暴露出许多弊端,如所有权基础上的自然遗产管理混乱,自然遗产经营权配置不合理,以及欠缺对自然遗产相邻权的规定等。这些产权制度方面暴露的问题,对于自然遗产的保护无疑是不利的。通过对自然遗产保护中产权问题的探析和国外在自然遗产保护方面经验的借鉴,对我国自然遗产保护产权权利束中的所有权、经营权和相邻权的完善提出了几点建议。

Relations between Environmental Right for Citizens and the Right to Use Environmental Resources owned by Company and Enterprise

Abstract

From angles of administrative law and private law, the article analyzes relations between environmental right for citizens and the right to use environmental resources owned by company and enterprise and points out three principles to balancing two relations: A principle of equal protection, a principle that general interest is superior to special interest as well as taking an account for special interest, in specific circumstances, for example, in the circumstance that clashes between environmental and economic interests can not be avoided, policy makers can put an emphasis on more important social interest according after considering weight of each interest. Finally, the article reaches a conclusion that China should establish system of environmental right for citizens from legislative and administrative levels so that a harmonious society can be constructed with guarantee.
