电子货币的发展对日本货币政策有效性的影响

日本作为亚洲成熟金融货币体系的代表,电子货币的迅速发展及其对货币政策的影响效果是值得我们探讨和借鉴的.基于巴塞尔委员会对电子货币的定义,日本银行按年度发布了2007～2008财年的电子货币及其他货币供给数据.借助这些数据,可以检验近两个财政年度日本电子货币的发展对日本央行货币政策有效性是否产生值得关注的影响,即日本电子货币的替代效应对央行的各层次货币乘数是否产生显著的影响,以及日本银行的电子货币发展状况调查结果与结论能否指引央行有效地制定和实施在电子货币条件下的货币政策.     

美国量化宽松政策对亚太新兴市场国家的影响

量化宽松是美联储在通货紧缩下所采取的一种直接创造货币、扩大央行资产负债表规模的非传统货币政策。量化宽松将给我国等新兴市场国家造成较大的负面效果,建议采取临时性资本管制、针对性量化政策、建立区域货币离岸市场、加快经济结构转型等对策来应对。     

Distress rentals and the land rental market as a safety net: contract choice evidence from Tigray,Ethiopia

Rural households in the semiarid Northern Ethiopian highlands are net buyers of food. Crop failure due to erratic and unpredictable rainfall occurs frequently and leads to food shortages and income shocks. The renting out of land may be one of the coping responses of households exposed to shocks. We developed a theoretical household model for poor landlord households capturing their contract choice response to downside production shocks. We tested econometrically whether contract choice may depend on poverty, capital constraints, production risk and random shocks. The multinomial logit model estimates show that poor households experiencing random shocks are more likely to choose fixed‐rent contracts as a distress response to shocks, suggesting that fixed‐rent contracts may be used to meet immediate needs, but at the expense of future incomes. We also found that fixed‐rent contracts are preferred when ex ante production risk is low, while sharecropping is more likely where production risk is high. Finally, we found an indication that the choice of a fixed‐rent contract as a coping response to shocks comes as a last resort after all other means of coping are exhausted.     

Methods and tools for integrated assessment of land use policies on sustainable development in developing countries

For stimulating sustainable development in developing countries, land use patterns and land use changes are considered critical, and therefore effective and efficient land use policies are needed. In this paper we present a methodological framework that has been developed in a joint European and developing countries project (LUPIS – Land Use Policies and Sustainable Development in Developing Countries), to assess the impact of land use policies on sustainable development in developing countries. An illustrative application is presented for a case study in China, where water pollution due to agriculture in Taihu Basin is a major problem.     

Temporal and spatial variability of agricultural land loss in relation to policy and accessibility in a low hilly region of southeast China

The temporal and spatial patterns in land use change in a low hilly region in southeast of China was analyzed from maps of converted agricultural land for 1999–2006. The factors driving farm land conversion was analyzed using logistic regression models. The amount of agricultural land loss varied temporally, and the spatial distribution of converted agricultural land patches decreased from low to high altitudes in the study area. Analysis using logistic regression models showed that good accessibility sped up the conversion of agricultural land to other uses, the elevation of a parcel lowered the risk of conversion, and agricultural land conversions are highly correlated with its adjacent or neighboring parcels’ land use, with the probability of being converted decreasing as the distance to nearest construction land increases. In addition, land use policy, especially the land use regulation policy issued by the central government decreased the agricultural land loss, and the more stringent regulation on cultivated land conversion lowered the possibility of conversion from cultivated land to other use.     

论WTO规则约束下地方政府在外贸领域的自主创新促进政策

为了鼓励出口企业自主创新,特殊经济区的地方政府可对国家没有实行全额出口退税但具有中国专利、已登记作品版权或自有出口商标的产品实行出口货物增值税未退进项税额地方财政部分返还政策,沿海经济发达地区的地方政府可对出口产品实行受托设计项目营业税地方财政减半返还政策和免费提供海外市场自主知识产权覆盖公共服务政策。     

相关政策能否营造系统化军民资源拓展空间——基于军民资源政策的实证评价

拓展军民资源是我国破解资源约束、实现结构优化、促进经济社会发展的重大战略举措。基于1978-2021年出台的79份军民资源政策,通过政策文本量化分析,构建基于PMC指数模型的军民资源政策评价指标体系,从政策属性、政策内容、政策理念、政策实施4个维度刻画军民资源政策对军民资源拓展的支撑效果。研究结果显示,不同等级军民资源政策均较好地贯彻了军民资源拓展的指导思想。其中,PMC指数得分较高的军民资源政策场域广阔,能够为更多场景中的军民资源拓展提供空间;PMC指数得分较低的军民资源政策能释放更多的治理资源存量,发挥政策聚焦优势和比较优势,提升军民资源拓展水平。     

城市科技创新人才政策扩散动力因素时空差异研究

科技创新人才是城市提升创新能力的核心资源,是科技进步的关键要素。科技创新人才政策作为城市争夺人才的工具,被各个城市广泛采纳和使用。以161个城市为研究对象,运用事件史分析方法,探寻城市科技创新人才政策扩散的动力因素并进行时空差异分析。研究发现,城市科技创新人才政策扩散具有双重动力因素：在需求拉动因素中,经济发展水平和财政收入是影响城市科技创新人才政策扩散的主要因素;在压力推动因素中,行政指令、府际竞争和社会舆论显著影响城市科技创新人才政策扩散;在政策扩散平稳增长期,双重动力因素共同作用于政策扩散过程,而在政策扩散加速和减速增长期,城市科技创新人才政策扩散动力因素存在差异;在东、中部地区,压力推动因素占据主导,而在西部地区,双重动力因素都发挥重要作用。     

通胀—增长权衡和中国菲利普斯曲线的平坦化

近年来发达经济体出现了菲利普斯曲线平坦化现象,但有关中国的研究尚缺乏共识。本文基于实证和理论分析,系统研究了中国菲利普斯曲线的平坦化问题。首先,结合货币政策冲击和月度SVAR框架,发现通胀的响应程度在2010年后大幅下降。由于证据显示总需求曲线并未平坦化,因此通胀响应弱化可解读为菲利普斯曲线的平坦化。数据显示,菲利普斯曲线平坦化与生产率增长放缓同时发生,因此,本文在标准DSGE模型中引入纵向内生增长渠道,该渠道基于研发投入和知识资本积累,从而使生产率内生于经济周期。研究发现：(1)内生增长渠道放大了需求冲击对产出的影响,但缩小了需求冲击对通胀的影响;(2)内生增长渠道改变通胀和增长之间的替代关系,但不改变边际成本向通胀的传导。分段估计显示,2010年后,通胀和增长的关系弱化是边际成本传导变弱和内生增长渠道变强共同作用的结果。本文认为,由于菲利普斯曲线的平坦化,中央银行应继续坚持稳增长和就业优先战略,关注但不必过于担心由此引发的通胀压力。
