农机燃油补贴政策满意度影响因素分析——基于山西省问卷调查

采用对山西省领取农机燃油补贴的主体——农户和农机户的调研数据,分析了领取主体对现行农机燃油补贴政策的满意度,并运用Logistic回归模型研究了影响相关补贴政策满意度的因素。模型结果显示:对农户进行农资综合直补而言,受教育程度、对农机燃油补贴程序的满意度等因素对农机燃油补贴政策的满意度有显著影响。对农机户进行燃油补贴而言,对农机燃油补贴金额的满意度这一因素对农机燃油补贴政策满意度的贡献率最高;农机作业支出变动、对农机燃油补贴政策的了解度、能否推动领取主体作业积极性、对政府管理部门工作的满意度、对农机燃油补贴程序的满意度等因素,对农机燃油补贴政策的满意度均有较显著影响。因此,重点需要提升领取补贴主体的教育水平和加强政府在补贴发放中的主导作用。     

The Effect of Decisions About Spent Nuclear Fuel Storage on Residential Property Values

National, regional, state, and local surveys have revealed that people have intensely negative images of "nuclear" and "radioactive" technologies, activities, and facilities, as well as associated fears of stigmatization. In light of these perceptions, the debate over where to temporarily store or permanently dispose of spent nuclear fuel (at the reactor site, an interim storage facility, or a permanent repository) provokes immense concern among possible host jurisdictions. To address these concerns, one needs to know if people's subjective opinions conform with the choices they make and are therefore reflected in their economic behavior. Argonne National Laboratory researchers used a hedonic model to complete a study of residential property value dynamics over a 5-year period within a 15-mile radius of two California nuclear power plants. They tracked the economic ramifications of decisions about the spent nuclear fuel stored at those reactors. The study revealed that no significant negative effects on residential property values resulted from a decision to move spent nuclear fuel from wet storage to a dry-cask storage facility or from a request to extend the reactor operating permit (given future changes in the type of nuclear fuel storage facility that would accompany such an extension).     

中国燃料油期货市场动态套期保值研究——基于Copula-GARCH模型的实证分析

为了更好地规避中国燃料油市场价格风险,利用Copula函数的秩相关系数代替皮尔逊线性相关系数,并用GED-GARCH模型求出燃料油现货和期货收益率的动态标准差,从而建立动态的最小方差套期保值模型,并对2009-2012年中国上海市燃料油期货进行套期保值策略分析.实证结果表明:与传统线性最小方差套期保值模型相比,动态套期保值模型提高了中国燃料油期货市场的套期保值有效性;具体而言,在样本区间内,动态模型的套期保值有效性为44.76%,比传统模型的有效性提高了32.1个百分点.

楚简“逸诗”《多薪》补释

新近发表的上海博物馆藏楚简《多薪》一篇简一“兄及弟淇,鲜我二人”中的“淇”应读作“綦”,通“繄(殹)”,而“淇鲜”当为“鲜淇”的误倒。从文献中看,墨子以“长松、文梓”作为楚地的代表性良木,而《多薪》则称“多薪多薪,莫如松梓”,因此《多薪》当为楚地之作。而其诗意则在于用松的常青来比喻兄弟之情。     

燃油税实施效果评价——基于北京地区的调查报告

2009年1月1日起,燃油税开始在全国范围内征收.燃油税改革关系重大,涉及中国多数的企业、家庭和住户的工作与生活,本研究报告对燃油税改革的实施效果进行快速跟踪调查,一方面作为对这项政策实施效果的回馈,另一方面则希望能够通过公众的反映以及对实际状况的分析来为政策实施过程中可能出现的问题提出解决的思路.     

Emergent Management Strategies in a Public Agency: A Case Study of Alternative Fuel Vehicles

The ability of public organizations to invest in emerging technologies is dependent upon the degree to which they can effectively manage the risks of being a lead-user in a political environment. However, little is known about the dimensions and implications of the different forms of risk faced by innovative public organizations as well as the strategies employed to manage them. This paper addresses these issues by studying how one public agency implements a program of replacing its transportation fleet with alternative fuel vehicles (AFVs).
