在供给侧结构性改革背景下,政策是进行面源污染防治的有效工具。市场经济环境下,农户的行为逻辑受多元因素影响。政策作为影响第一产业发展的关键要素,对农户具有制约、引导、激励和调节作用。与此同时,农户也对政策的推行效果具有深刻的影响。本文在进行面源污染防治政策演进分析时,尝试从经济激励引导型、命令控制型以及协同辅助型等不同政策类型入手,重视经济激励和制度激励的作用,收紧面源污染防控的监管口径,建立差别化的污染治理衡量机制,并重视技术推广在污染防控中的作用。提高农户积极性,提升农户对政策的反馈效果,最终提高农户对面源污染防治政策的遵循水平,提升面源污染防治效果。 相似文献

A goal of this paper is to make sense of the seemingly puzzling behavior of interest rates and inflation – and the role of central banks in that behavior – during and after the Great Recession, particularly in the United States. To this end, we construct a model in which government debt plays a key role in exchange, and can bear a liquidity premium. If asset market constraints bind, then there need not be deflation under an indefinite zero interest rate policy (ZIRP). Further, ZIRP may not be optimal under these circumstances. A Taylor-rule central banker could be subject to a ZIRP trap and persistently undershoot target inflation. As well, a liquidity premium on government debt creates additional Taylor rule perils, because of a persistently low real interest rate. We make a case that this is the key policy predicament currently faced by many central banks in the world. 相似文献

This paper aims to analyse the feasibility of policy coordination among the ASEAN-5 economies. This is done by determining whether they experience symmetric responses to common shocks. Given that the problem of dimensionality plagues large-scale macroeconomic modelling, a Global VAR model by Pesaran, Schuermann, and Weiner (2004) and Dees, Mauro, Pesaran, and Smith (2007) is used. The results in this paper provide some weak evidence of symmetric responses to the common (global) shocks of interest: a US monetary policy shock, a US output shock, a Chinese output shock; an oil price shock. Shocks from the US produced the most symmetric responses. The lack of symmetry in some cases has implications for further policy coordination. Since migrant remittances could provide an adjustment mechanism, further labour market integration is needed as it currently lags behind trade and financial integration in the region. 相似文献

We compare certification to a minimum quality standard (MQS) policy in a duopolistic industry where firms incur quality-dependent fixed costs and only a fraction of consumers observe the quality of the offered goods. Compared to the unregulated outcome, both profits and social welfare would increase if firms could commit to producing a higher quality. An MQS restricts the firms׳ quality choice and leads to less differentiated goods. This fuels competition and may therefore deter entry. A certification policy, which awards firms with a certificate if the quality of their products exceeds some threshold, does not restrict the firms׳ quality choice. In contrast to an MQS, certification may lead to more differentiated goods and higher profits. We find that firms are willing to comply with an ambitious certification standard if the share of informed consumers is small. In that case, certification is more effective from a welfare perspective than a minimum quality standard because it is less detrimental to entry. 相似文献

Weak institutional development and information flows have constrained the extent to which the smallholder farming sector in developing countries can significantly drive growth and poverty reduction. This is despite widely implemented economic liberalisation policies focussing on market efficiency. Farmer organisations are viewed as a potential means of addressing public and private institutional failure but this has frequently been limited by inequalities in access to power and information. This article investigates two issues that have received little research attention to date: what role downward accountability plays in enabling farmer organisations to improve services and markets, and what influences the extent to which downward accountability is achieved. Kenya Tea Development Agency (KTDA), one of the largest farmer organisations in the world (>400,000 farmers) is examined alongside wider literature. Mixed methods were used including key informant interviews, and eight months of participant observation followed by a questionnaire survey. The article concludes that without effective downward accountability farmer organisations can become characterised by institutions and mechanisms that favour elites, restricted weak coordination and regulation, and manipulated information flows. This in turn reduces individuals’ incentives to invest. If farmer organisations are to realise their potential as a means of enabling the smallholder sector to significantly contribute to economic growth and poverty reduction, policy and research needs to address key factors which influence accountability including: how to ensure initial processes in formation of farmer organisations establish appropriate structures and rules; strong state regulation to enhance corporate accountability; transparent information provision regarding actions of farmer organisation leaders; and the role independent non-government organisations can play. Consequently attention needs to focus on developing means of legitimising rights, building poor people's capacity to challenge exclusion, and moving from rights to obligations regarding information provision. 相似文献

The daily trip to work is ubiquitous, yet its characteristics differ widely from person to person and place to place. This is manifested in statistics on mode and distance of travel, which vary depending on a range of factors that operate at different scales. This heterogeneity is problematic for decision makers tasked with encouraging more sustainable commuter patterns. Numerical models, based on real commuting data, have great potential to aid the decision making process. However, we contend that new approaches are needed to advance knowledge about the social and geographical factors that relate to the diversity of commuter patterns, if policies targeted to specific individuals or places are to be effective. To this end, the paper presents a spatial microsimulation approach, which combines individual-level survey data with geographically aggregated census results to tackle the problem. This method overcomes the limitations imposed by the lack of available geocoded micro-data. Further, it allows a range of scales of analysis to be pursued in parallel and provides insights into both the types of area and individual that would benefit most from specific interventions. 相似文献

府际关系协调有利于实现创新资源、要素的有效汇聚与整合,进而提升政策有效性。以京津冀为例,构建中央-地方多层级府际关系模型,分析中央政策主体合作网络特征与政策扩散特征、地方政策主体合作网络特征与政策执行特征的相关性。研究发现,中央政府部门间形成了以科技部为核心的核心—边缘网络结构特征;北京市政府部门间呈现出以中关村科技管理委员会为核心的核心-边缘网络结构特征;天津市政府部门间呈现出以天津市科学技术委员会为核心的星型网络结构特征;河北省则没有形成稳定的网络关系。中央政策主体合作网络中的度中心性与政策扩散广度具有相关性;地方政策主体合作网络中介中心性、度中心性与政策执行强度具有相关性。 相似文献

高技能人力资本对于我国经济转型的重要性不言而喻。本文以2009—2012年间39个城市集中出台的地方人才引进政策为准自然实验,采用多期政策的双重差分法,结合机制分析和异质性分析,探究了人才政策出台前后区域创新能力的变化及其背后的机制和深层次原因,并分析政策效应在不同的地区营商环境、科教事业投入力度、知识产权保护程度下的差异。本文主要结论包括,地方人才引进政策总体上提高了当地的专利授权总量和专利价值总量;显著增加了研发投入的规模,但创新效率没有得到明显提升;在营商环境较差的地区,政策的效应侧重于提高专利数量,营商环境较好的地区则侧重于提升专利价值;在科教投入力度本身就很大的地区,政策效果较小,在科教投入弱的地区效果会更明显;在知识产权保护程度弱的地区,政策效果更多地表现为提高专利数量,保护程度强的地区,则侧重于提升专利价值。上述结论对地方政府优化人才激励政策、实施创新驱动发展战略具有一定的政策启示。 相似文献

本文利用SVAR模型脉冲偏导分离技术,从利率市场化和影子银行两个维度测算了金融市场化进程对货币政策不同传导渠道相对地位的影响。实证结果揭示了中国货币政策传导的一些重要特征:第一,以信贷渠道为代表的数量化渠道效应要强于以利率和汇率渠道为代表的价格渠道,并且该结果没有因金融市场化的推进而改变。第二,利率市场化的推进主要强化了利率渠道的作用,但一定程度上弱化了其他渠道尤其是信贷渠道的作用。第三,影子银行的发展,强化了资产价格渠道的效应,而相对弱化了信贷渠道和利率渠道的效应。研究为在金融与实体经济市场仍存在一定程度摩擦的条件下,央行采用价格与数量货币政策调控方式有机结合的必要性与有效性,提供了实证支持。同时研究还表明,要充分发挥利率市场化改革完善货币政策价格传导机制的作用,既需要加强对各种形式金融创新的监管,还需要实体经济体系进一步市场化改革相配合。 相似文献
