农户从事生态循环农业意愿与行为的决定:市场收益还是政策激励?

发展生态循环农业是我国新时期转变农业发展方式的战略选择,农户是生态循环农业的经营主体和利益相关者,厘清农户参与生态循环农业的根本动机,对于制定有效的生态循环农业推广措施具有重要意义。文章基于湖北省391份农户调查数据,首先,在文献回顾的基础上提出市场收益、政策激励对农户生态循环农业从事意愿与行为影响路径的基本假设,并利用OLS方法分析市场收益和政策激励对农户从事生态循环农业意愿与行为的影响;其次,运用优势分析法评估市场收益类变量和政策激励类变量影响农户意愿与行为过程中的相对重要性;最后,通过交互效应检验市场收益类变量和政策激励类变量间的交互作用。结果表明:收入预期对农户从事生态循环农业的意愿与行为均有直接的积极影响,是促进农户从事生态循环农业的最重要的因素;焚烧秸秆惩罚政策和废弃物资源化补贴政策对农户从事生态循环农业的意愿有积极影响,沼气池建设补贴政策和废弃物资源化补贴政策对农户生态循环农业行为有促进作用;收入预期与废弃物资源化补贴政策在影响农户生态循环农业行为的过程中存在互补效应。本研究认为,市场收益是刺激农户采纳生态循环农业生产模式的首要因素,因此,要着力完善生态农业市场体系,增强生态农产品的市场竞争力,提升农户对生态循环农业的盈利信心;另外,政策激励对于农户采纳生态循环农业具有促进作用,应该做到约束与激励并行,同时注意加强农业政策的科学设计与落实执行。     

Dividing and Uniting Through Naming: The Case of North Carolina's Sea-Level-Rise Policy

Opponents of a proposed sea-level-rise policy in North Carolina, USA, reasoned rhetorically to promote a narrative claiming that the policy supporters’ efforts had failed to meet the criteria of “good” science and the American dream expectancy of “progress.” The critics worked to hinder policy adoption by naming as “villains” scientists who provided research to support the proposed policy. In addition, the opponents named their own efforts to prevent policy based on “bad” science that would “destroy” the American dream as “heroic.” To more effectively respond to such narratives, scientists and policy proponents need to shift away from reporting just climate change “facts” in the attempt to gain stakeholder support for mitigation and adaptation initiatives. They need to move toward reasoning rhetorically to construct narratives that encourage the public to name them as the “heroes” who will achieve the American dream by their actions to mitigate climate-change outcomes.     

我国强制性清洁生产审核法律政策形成过程的研究与分析

在资源短缺和环境容量不足的双重约束下。清洁生产成为我国工业可持续发展的必然选择，而清洁生产制度的制定和完善一是促进我国清洁生产向纵深发展的关键。本文回顾了我国清洁生产领域相关政策法规的制定和实施情况，对存在的问题进行了总结分析。并对2005年12月13日国家环保总局出台的《重点企业清洁生产审核程序的规定》做了重点说明,提出了目前面临的主要任务。     

基于复杂系统建模的水管理政策研究进展

基于Agent的建模方法（ABSS）通过自下而上的方式，考察系统中主体的不同状态和行为特征、主体与环境的作用、主体之间的作用，来表征系统的宏观特征，是进行复杂社会环境系统分析和政策研究的重要手段，在水资源、水环境管理系统中得到了有效的应用。本文在大量文献调研的基础上，讨论了ABSS建模方法的基本原理、主要特征、系统构成、分类方法和开发工具等特征，总结了其供水系统发展、水资源分配和流域水资源管理、农业土地和水资源利用、居民用水行为、农业污染控制及人类活动的水环境影响等方面的应用，分析了其在研究内容、研究方法、研究结果等方面的发展趋势，讨论了利用该方法研究我国水资源管理和水污染控制政策的必要性和重要性。     

农业贸易政策环境影响评价的案例研究

随着国际贸易自由化程度的提高,贸易与环境问题越来越引起人们的重视。对贸易政策进行环境影响评价。指导贸易政策的制定。是解决贸易所带来的环境问题的重要途径。了解中国入世后一系列的农业政策调整会在多大程度上影响环境。对于新的政策决策具有指导意义。本文在总结贸易政策环境影响评价研究步骤和方法的基础上。对农业贸易政策环境影响评价的特点进行讨论,并以河北省迁安市小麦种植业为例,进行农业贸易政策环境影响评价的案例研究。由于农业贸易政策直接作用于农业生产经营活动。再通过农业生产经营等活动间接地影响环境质量状况。本文借助转移矩阵方法进行分析评价。     

The Clean Development Mechanism and Sustainable Development in China''''s Electricity Sector

1 INTRODUCTIONEnergy and environmental issues in China have receivedsignificant attention in both the peer-reviewed literatureand in international energy and environmental policymaking in the last number of years. China's coal dominatedenergy consumption results in significant regional pollutionproblems, most notably acid rain that affects nearly 1/3rdof China's landmass and air pollution that plagues manyof its major cities. China now ranks as the top emitterof sulphur dioxide (SO2) pol…     

中日韩循环经济政策比较研究

在中国经济迅猛发展的同时，投资主导型的经济模式中环境保护要素的缺失导致我国工业化发展旱、中期的资源、能源约束、效率低下和浪费严重。在我国实施循环经济刻不容缓。循环经济政策是依据不同的社会、经济和环境条件而制定的。由于历史的原因，中日韩三国在地缘关系、政治传统、风俗习惯、文化教育等内在制度和外在制度彼此趋同，反映在循环经济政策的制定、执行上也有某些相似的地方。对三国循环经济的历史和现状进行比较研究，得出有益于我国的经验，无疑具有很重大的现实意义。采用制度变迁的基本理论作为指导，运用历史研究法、调查研究法等方法进行研究，对中日韩循环经济政策演变的历程进行系统梳理和比较，深入全面地考量其指导思想和举措的选择动机，系统广泛地从多方面研究中日韩循环经济政策。并将三者加以比较，以得出对我国循环经济的发展具有较强借鉴意义的经验，更好地推进循环经济在我国的发展。     

Water Resource Management in Botswana: Balancing Sustainability and Economic Development*

Botswana is a rapidly developing country in southern Africa. Over the last three decades, diamond mining and tourism have provided double-digit rates of economic growth. Yet most of Botswana’s land is in the Kalahari desert where the climate is subject to sustained periods of severe drought. In this environment, water resources are the most crucial of all environmental resources. Water use directly affects economic development because water utilization impacts all the major national economic sectors. A sustainable water use resource management plan must stretch several decades into the future to assure the availability of adequate supplies of water to future generations while not compromising the ability of the current generation to reasonable rates of economic development. Yet thinking about sustainability is present in Botswana water policy mostly only in rhetoric. A series of cultural traditions and political constraints, coupled with bureaucratic managerial weaknesses, serve to maintain a system of water allocation that is unsustainable in the long run and inefficient in the short-term. Unless sustainable water use patterns are adopted, the results for the short-term, as well as the long-term, will be devastating. Drawing on data obtained through a series of interviews with government officials, leaders of non-governmental organizations (NGOs), and water resource researchers, this paper explores water policy in Botswana within the larger context of sustainable natural resource management practice and the pressures of economic development. This research was partially funded under U.S. Department of State, College and University Affiliations Grant # ASCS-1095.     

基于政策工具的中国生物质发电补贴政策评估

生物质发电兼具环境效益与社会效益,对支撑中国推进能源消费革命和乡村振兴,实现碳达峰、碳中和目标具有重要意义。对截至2020年12月31日国家层面出台的生物质发电补贴相关政策进行梳理,运用政策工具理论与方法,从环境、供给、需求3个角度,研发、投资推广、原料资源、生产并网、消费5个环节评估生物质发电补贴政策的实施情况和存在问题,提出生物质发电补贴政策的优化建议。结果表明,现阶段生物质发电产业在研发、原料供应、基础设施领域补贴不足,财政补贴有逐步退坡并向市场机制转变趋势,但相应政策工具及制度创新尚存在欠缺。中国生物质发电补贴政策应在更多关注技术研发、充分涉及中间链条、完善激励机制等方面不断改进,并大力强化市场培育,在配套措施保障下引入市场机制,以促进产业长期可持续发展。     

No evidence of systematic pre-emptive loggings after notifying landowners of their lands’ conservation potential

Landowners can intentionally impair biodiversity values occurring on their land to pre-empt biodiversity protection. This often leads to significant negative effects on biodiversity. We studied whether landowners in Finland engaged in pre-emptive loggings after they were notified that their wooded mires are candidate sites for a mire protection program. After the notification, harvesting rates of the candidate wooded mires were significantly lower compared to harvesting rates of similar but non-candidate wooded mires. Annual and monthly harvesting rates indicated that notifying landowners of the conservation potential did not launch systematic pre-emptive logging behavior. Nevertheless, part of the candidate wooded mires were logged, so some landowners place more weight on other values than the biodiversity ones. Pre-emptive behavior has been observed in other studies suggesting that many country- or system-specific factors such as cultural background or level of compensation can affect landowners’ behavior.Electronic supplementary materialThe online version of this article (10.1007/s13280-020-01354-4) contains supplementary material, which is available to authorized users.
