我国经济型饭店的发展战略

国内外旅游业的迅速发展,尤其是大众化旅游的发展,使经济型饭店日益成为业界关注的焦点。本文在对经济型饭店的概念和特征进行探讨的基础上,着重从市场环境和供给两方面分析了我国经济型饭店的发展现状,并针对行业存在的问题以及面临的国内外市场竞争,提出了现阶段我国经济型饭店行业应该采取的战略举措．即变革企业制度,调整经营方式,实行行业地域联合与集团经营,细分行业市场,提升信息技术水平,改进智力因素,强化行业管理等。     

让实体经济和虚拟经济的耦合协调度最优

自借贷资本从商业资本和产业资本分离之日起,虚拟经济就已产生,并随着经济的发展规模逐步扩大。虚拟经济与实体经济发展平衡时,彼此促进增长;当两者发展程度不协调时,就会出现泡沫经济。在新一轮经济形势下,如何让两者的耦合协调度最优?文中对虚拟经济增殖过程进行了一定程度的揭示,并为使两者耦合协调度最优提出一点建议。     

演变趋势、保障体系与创意人才生态系统构成

创意人才是创意经济时代最宝贵的资源。基于自然生态系统的构成及演变视角研究创意人才的成长同组织以及环境之间的互动机理,可以发现:创意人才生态系统镶嵌于创意网络矩阵当中,由生态群落和创意环境组成,两者相互影响、相互渗透;系统演变遵循多样维持、遗传改变、模仿学习和竞合共生机制;系统的健康有赖于人才政策、产业规划、教育手段、管理方式等方面的保障。     

论文化旅游城市综合吸引力的提升——太原模式研究

对文化旅游城市的开发建设应使之兼具观光型传统旅游目的地和体验型现代旅游目的地的特征,文章以太原为研究对象,探讨提升文化旅游城市综合吸引力的路径和模式。在盘点太原的历史文化资源和自然资源,分析其旅游市场客源的基础上,进行旅游区域形象设计,继而通过地区营销组合,将丰厚的历史文化资源与现代的文化创造有机整合包装起来。使历史文化资源转化成现实的文化生产力,必将能极大地带动城市经济的进一步发展。     

央行政策沟通的金融资产价格稳定效应——以中国股票市场为例

本文研究中国央行不同形式、不同主体、不同意图、不同时间政策沟通的稳定金融资产价格效应以及央行"言行一致"对政策效果的影响.实证结果显示:(1)央行沟通能够显著影响股票价格且能够降低资产价格波动.(2)从形式看,书面沟通较口头沟通对市场影响更大;从主体上看,行长沟通效果好于他人沟通;从政策意图上看,紧缩意图的政策效应大于...     

多哈回合农业谈判对我国农产品贸易政策的影响

我国是一个农业大国,农业部门有其特殊性和重要性,多哈回合农业谈判一直倍受关注。多哈回合核心部分是农业框架协议,我国应在国内支持、出口竞争、市场准入等方面给予高度关注。对此,我国农产品贸易政策必须进行重要调整,即从高价格、高关税和非关锐手段的保护向适应WTO规则的保护转变。从直接干预向间接干预转变。     

Decision-making in incomplete markets with ambiguity—a case study of a gas field acquisition

We apply utility indifference pricing to solve a contingent claim problem, valuing a connected pair of gas fields where the underlying process is not standard Geometric Brownian Motion and the assumption of complete markets is not fulfilled. First, empirical data are often characterized by time-varying volatility and fat tails; therefore, we use Gaussian generalized autoregressive score (GAS) and GARCH models, extending them to Student’s t-GARCH and t-GAS. Second, an important risk (reservoir size) is not hedgeable. As a result, markets are incomplete which makes preference free pricing impossible and thus standard option pricing methodology inapplicable. Therefore, we parametrize the investor’s risk preference and use utility indifference pricing techniques. We use Least Squares Monte Carlo simulations as a dimension reduction technique in solving the resulting stochastic dynamic programming problems. Moreover, an investor often only has an approximate idea of the true probabilistic model underlying variables, making model ambiguity a relevant problem. We show empirically how model ambiguity affects project values, and importantly, how option values change as model ambiguity gets resolved in later phases of the projects. We show that traditional valuation approaches will consistently underestimate the value of project flexibility and in general lead to overly conservative investment decisions in the presence of time-dependent stochastic structures.     

Personalized goal-based investing via multi-stage stochastic goal programming

In this paper, we propose a goal-based investment model that is suitable for personalized wealth management. The model only requires a few intuitive inputs such as size of wealth, investment amount, and consumption goals from individual investors. In particular, a priority level can be assigned to each consumption goal and the model provides a holistic solution based on a sequential approach starting with the highest priority. This allows strict prioritization by maximizing the probability of achieving higher priority goals that are not affected by goals with lower priorities. Furthermore, the proposed model is formulated as a linear program that efficiently finds the optimal financial plan. With its simplicity, flexibility, and computational efficiency, the proposed goal-based investment model provides a new framework for automated investment management services.     

外汇储备增长对我国物价影响的实证分析

2007年以来,我国物价水平出现持续攀升的势头。2008年1～4月份,居民消费价格水平同比上涨8.2%。与物价上涨相对应的是我国外汇储备水平创出了历史新高,截至2008年6月末,我国外汇储备余额达1.8万亿美元。那么,外汇储备增长与物价上涨之间有没有直接的联系?本文从短期和长期两个视角,理论和实证相结合探讨了我国外汇储备增长对物价上涨的影响及其作用机制。     

我国进行国际税收竞争的最优战略与策略分析

本文依据国际税收竞争对我国的积极意义以及我国是发展中大国的战略定位,认为我国应该采取"积极、适度竞争,理性、必要协调"的战略;在竞争策略的选择上,通过对我国主要资本来源国对待本国资本海外投资的规定以及竞争对手国吸引外资相关做法的研究,提出我国应选择"低税率、宽税基、少优惠"的竞争方式和手段,并应注重形成有比较竞争力的税收制度,而不应进行频繁的政策调整.
