This paper performs a plot-level analysis of the impact of land rental market participation and off-farm employment on land investment, input use, and rice yields for 215 plots cultivated by 52 households in three villages in Northeast Jiangxi Province. Our findings show that households that rent extra land are relatively more productive, but contradict results of earlier studies which found that tenure status of plots affects the level of land investments. We further find that off-farm employment does not significantly affect rice yields. This result contradicts those of earlier studies which found that the negative lost-labor effect of off-farm employment dominates the positive income effect. Another novel finding is that people working locally off-farm tend to switch from green manure planting towards the use of organic manure on their rice plots. We conclude that policies that will further stimulate the development of land rental markets, which is still in its infancy, can contribute significantly to higher rice production in Southeast China. Another implication of our results is that worries about the negative impact that the continuously growing off-farm employment may have on China's goal to remain self-sufficient in grain production are less relevant at the moment for the region examined in our study.  相似文献

综合运用2009-2017年A股上市公司数据,通过长、短期社会责任的影响对比,考察了在面对经济政策不确定性的冲击时,企业社会责任对融资约束的影响效应,并论证了不同政策不确定程度下的效应表现机理。结果表明:企业社会责任具备"累积效应",长期社会责任的融资约束缓解作用强于短期社会责任;企业社会责任也具备"保险效应",会显著削弱经济政策不确定性加剧融资约束的程度。进一步研究发现,高经济政策不确定性下:"累积效应"仍然存在,且会因长期社会责任"保险效应"加强而得到强化。不同产权性质下:国有企业的融资约束受政策不确定性影响较小,且"双效应"更稳定;而非国有企业的社会责任对融资约束的缓解作用更强,但受经济政策冲击更大。研究揭示了企业社会责任对融资约束的积极效应,呼吁企业应积极履行社会责任并值得长期坚持。  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

In the search for solutions to complex real-world problems, the benefits of transdisciplinary research (TDR) have been widely heralded. Land use science appears to be a designated field for TDR. However, to date, the additional expenses of TDR are accompanied by a so far not proved added value, and empirical findings are claimed to be scarce and dispersed over several disciplines and case studies.We reviewed 299 articles obtained from a structured literature search to (1) investigate the current differences between theory and practice, (2) identify empirical findings, and (3) ascertain the contributions of TDR to promoting sustainable land use management.Our results demonstrate that, in spite of an increasing conceptual consistency in the theoretical discussion of TDR, the implementation of TDR remains a substantial challenge, in part because of the gap between theory and practice. In addition, research on TDR is science and process centred. The benefits of TDR in addressing real-world problems within the field of land use remain unproven.  相似文献

Land use regulation has always been regarded as one of the most crucial means of macro-control of urban growth, which can affect a city’s land values directly and further determine related urban economic well-being. Since the New Type Urbanization Strategy proposed by the government in 2014, China’s mode of urban growth has been transformed from addressing “quantity” to “quality" in the urbanization process. In this case, the regulation of land use by the Chinese government plays a more important role in urban growth. With their planned land regulatory scheme, the various instruments employed by Chinese governments have quite different mechanisms influencing land prices. However, there are no rigorous studies focusing on the land use regulation system and its impact on land values to date, particular in China. This study seeks to explore how land use regulation affects urban land values through the systematic lens. We summarize the main land use regulatory instruments based on the analysis of China’s planned land use system and urban land banking system, including the construction land quota, constraints on the allowed floor area ratio (FAR) of each land transaction parcel, and land supply restrictions. A new dataset based on land transaction data from 2007 to 2016 that covers 286 prefectural cities from the country’s coastal, central, and western regions is used in the empirical analysis. The results show that the effects of the floor area ratio (FAR) on land values are significant and positive, with the residential and commercial land supply ratio being a key factor. Moreover, the results imply that the effects of constraints on FAR and commercial land supply vary between regions. These findings indicate that the Chinese land market is considerably distorted by excessive administrative interventions by local governments, in the stage of urban transition guided, the capable regulatory instruments could play an important role in adjusting urban land prices and hence impact on urban growth.  相似文献

On the basis of a liquidity management model, liquidity risks, defined as the probability of payment failures in a real-time gross settlement (RTGS) payment system, may either stem from liquidity management inefficiencies or insufficient cash balances. I will show that penalties charged on the amount of payment failures minimise liquidity risks without interfering with the bank’s technology preferences. I will instead show that liquidity requirements, although as effective as penalties to contain the risk of liquidity shortage, may distort the bank’s technology preferences and cannot stem liquidity management inefficiencies. I will also show that liquidity risks within RTGS payment systems are potentially smaller because they depend more on the liquidity management efficiency than on the randomness of cash inflows and outflows.  相似文献

Using of the results of survey questionnaires distributed to climate scientists who focus on the German Baltic coast, regional political decision makers on the German Baltic coast and weather observations from the same region, this paper assesses the existence of developing climate-change lore and the implications for the role of climate science in the science–policy interface. The Oxford Dictionary (1993) provides one definition of lore as ‘A doctrine, a precept; a creed, a religion.’ This is the definition adopted for this paper. The paper concludes that the discrepancies among weather observations, scientific assessments and decision makers’ perceptions suggest that climate-change lore exists, or is coming into existence. The paper then discusses the implications for the science–policy interface and suggests that given current trajectories, science could come to play a secondary role to climate-change lore in regional political decision making concerning climate change. To the truth-to-power model of the science–policy interface and the tenets of post-normal science, three additional possibly evolving science–policy configurations (as pertaining to the climate change issue) are offered.  相似文献

本文从商业银行流动性管理视角出发,探究银行微观主体行为如何影响宏观审慎与货币政策的协调。我们借鉴净稳定资金比例的设计理念,将商业银行的流动性管理行为纳入传统理论模型,刻画出两种流动性管理行为对货币政策信贷传导渠道效率的潜在影响及传导路径。在此基础上,采用我国50家商业银行2012年第1季度—2018年第2季度面板数据进行实证检验。我们发现,银行为提升长期流动性水平而进行的优化信贷资产结构的行为,能够显著提高货币政策传导效率。但是,部分净稳定资金比例较低的股份制银行和城市商业银行调整非信贷资产结构的行为则有可能降低货币政策传导效率。因此,在执行既有流动性监管措施的同时,关注与引导银行资产结构调整方式,对增强宏观审慎与货币政策的协调大有裨益。  相似文献

价值链作为组织和协调经济活动的微观机制,已使经济全球化和增长模式发生了深刻的变化。本文利用来自投入产出表的新方法,测度了广东省和江苏省全球价值链和国内价值链的水平。结果表明,粤苏两省切入全球价值链的倾向高于切入国内价值链的倾向,而对其它省份关联效应较大的行业基本上是中间品行业,且具有自然资源密集的特征。全球价值链与国内价值链之间的互动关系,则关系到我国产业升级的前景和区域经济协调发展的基础。  相似文献

我国财政改革中几个全局性问题的思考   总被引:1,自引:0,他引:1  
按照党的"十六大"提出的战略构想,未来20年里我们将完成经济体制转轨的任务,实现全面小康.这样的构想意味着,中国经济体制改革目标的实现已从政策设计的角度锁定在1978-2020年的时段内,我们正处在承前启后的转折点上.在政府主导的渐进路径上,政府既推进着市场机制的建立,也同时推动着计划手段的创新,在市场机制发挥作用的同时,又始终承担着计划体制下的诸多任务与责任.财政作为政府政策实施的财力保障,以自身的变动见证了这一过程,与体制转轨进程和经济运行状况有着深刻的互动关系.因此,在这样一个特殊时刻,对财政改革中的一些关系全局的问题进行思考、解释,不仅关系到财政自身的运行,无疑也将直接影响到整个经济发展的绩效.本文主要围绕三个方面的重大问题提出了分析的路径与依据,并做出了基本的评价.  相似文献
