基于农村居民现实最低养老需求,对我国财政的养老补贴支付能力进行测算分析。以修正恩格尔系数为基础测度了农村居民最低养老保险水平,并依据农村恩格尔系数及物价指数的历史变动趋势,预测了2010-2020年农村最低养老动态水平;利用财政收入规模的自回归模型预测了2010-2020年的财政收入规模,结合普惠型养老金总额应为财政收入的5%国际经验,对基本养老金以及最低养老需求占财政收入的比重进行了测算和评价。目前的基本养老金在短期内对改善农村老年人生活有重要作用,但长期来看还需要不断增加,应优化财政支出结构。  相似文献

我国以粮食直补为主体的粮食生产利益补偿机制,对稳定粮食生产、保护粮食安全和增加农民收入有着较大的促进作用;但也存在补贴额度较小、粮食最低收购价偏低、补贴标准不统一、行政成本过高等问题,而且没有考虑粮食主产区农业基础设施建设等公共产品不足及其政府的积极性,同时,粮食补贴普惠制本身也有局限性。应加大粮食补贴力度、改变补贴方式、统一补贴发放标准、降低行政成本,适当提高粮食最低收购价,加大对粮食主产区的财政转移支付力度,增加粮食主产区农业基础设施建设补贴。  相似文献

针对动态综合评价需要考虑被评对象的稳定性问题,提出了一种综合考虑指标权重、时间权重和稳定性的动态综合评价模型。定义了稳定因子来表征被评对象指标的稳定程度,采用离差最大化的方法确定指标权重,提出了一种基于极小范数时间权重确定方法。将所提模型应用于军事IP网络评价,结果表明该模型能够把被评对象的稳定性反映到评价结果中。  相似文献

We argue that to support agriculture–environmental policy decision making, stakeholders need ‘quantitative back‐of‐the‐envelope’ analysis that is timely and sufficiently accurate to make informed decisions. We apply this concept to the analysis of the supply of ecosystem services from agriculture. We present a spatially explicit production model and show how it can be used to derive the supply of ecosystem services in a region. This model shows that the supply of ecosystem services can be derived from the spatial distribution of opportunity cost of providing those services. We then show how this conceptual model can be used to develop a minimum‐data (MD) approach to the analysis of the supply of ecosystem services from agriculture that can be implemented with the kinds of secondary data that are available in most parts of the world. We apply the MD approach to simulate the supply of carbon that could be sequestered in agricultural soils in the dryland grain‐producing region of Montana. We find that the supply curve derived from the MD approach can approximate the supply curve obtained from a more elaborate model based on site‐specific data, and can do so with sufficient accuracy for policy analysis.  相似文献

The field of International Business (IB) has traditionally focused on the crossing of national boundaries. In this Perspective, we argue that organizational, knowledge domain, and language boundaries are equally important for understanding translation activities in cross-border business. We integrate three kinds of translation (organizational translation and knowledge translation from Organization Studies and interlingual translation from Translation Studies) to deepen our understanding of core IB phenomena and pose new research questions. We introduce the framework of a translation ecosystem for integrating the micro perspective of translating agents, the meso perspective of organizational units, and the macro perspective of the larger social and linguistic contexts that influence translation. This framework allows IB scholars to identify important but invisible boundaries in cross-border business. The translation ecosystem requires the kind of multi-level research that has been recognized as crucial for taking the field forward and offers the potential for making contributions both to IB and to translation research beyond the disciplinary boundaries of IB.  相似文献

Hotel owners and managers are increasingly outsourcing their spas to specialist firms that oversee the spa's operations and personnel. In such spas the assume the role of boundary spanners as they are responsible for overseeing the operational relationship between the hotel and spa companies. In this role, they are responsible for trying to satisfy the hotel and spa companies’ often contradictory expectations while also often adhering to two sets of operating guidelines. As a result, they may experience different levels of role conflict and role ambiguity than spa managers who oversee spas managed by the hotel. The results of a questionnaire completed by 166 hotel spa managers from spas managed by hotels and those managed by third parties found greater levels of these role stressors in managers of outsourced hotel spas. Based on these findings, research suggestions and managerial implications are discussed.  相似文献

The problem of sequentially estimating a location parameter and powers of a scale parameter is considered in the case when the observations become available at random times. Certain classes of sequential estimation procedures are derived under an invariant balanced loss function and with the observation cost determined by a convex function of the stopping time and the number of observations up to that time.  相似文献

Multinational corporations (MNCs) need to sense, source, and mobilize knowledge when and where it arises, whether at home, or elsewhere in the world. For this reason, MNCs benefit from employee networks of relationships that span across intraorganizational barriers, allowing for the efficient mobilization of knowledge across boundaries. Yet, which organizational members are more likely to be able to develop these boundary spanning networks? We leverage a unique data set from a large multinational corporation to empirically test a comprehensive model that captures the effect of an employee’s mandate, expertise, and behavioral orientations on her likelihood to span intraorganizational boundaries that manifest themselves in the form of hierarchies, intra-functional domains, and geographic territories. We find that the employees that are more likely to be boundary spanners are those having mandates with a global impact, high levels of expertise, and a collaborative orientation in their networking behaviors. In addition, we find that these effects are stronger for those employees that have large formal workflow networks.  相似文献
