异质性、外资企业生产率与产业集聚

本文采用2000~2007年工业企业数据,系统考察了外资企业与我国地区产业集聚之间的互动促进关系,并从企业规模、控制权性质两个维度分析不同外资企业与产业集聚之间互动关系的路径差异。结果发现:外资企业与地区产业集聚之间的互动促进关系主要是外资企业与其前后关联行业集聚之间的互动促进,外资企业与同行业的集聚并未形成相互依赖、相互促进的关系;外商独资企业与其前后向关联行业的集聚均存在互动促进,且外商独资与其后向关联行业的集聚之间形成的互动促进是外资企业与我国产业集聚互动促进的主要路径;中外合资企业仅与其前向关联行业集聚之间形成稳定的互动促进关系。     

从层级到网络:城市间关系研究的演进

城市间关系历来是城市地理学、城市经济学等相关学科研究的前沿领域之一,但相对于城市内部空间结构与经济机理的研究,此领域的研究比较薄弱.基于传统的中心地理论,城市系统理论将城市间关系简单地模型化为层级结构,从而掩盖了城市间关系的复杂性与多样性.世界城市网络的研究在很大程度上弥补了上述不足,并正得到越来越多学者的认可.城市经济学则在分析方法与理论工具方面与城市地理学的研究存在很大差异.本文对上述两大学科中关于城市间关系研究的主要文献进行综述,并梳理城市间关系研究的理论渊源与演进路径.

Combining Service Blueprint and FMEA for Service Design

This paper aims at combining the service blueprint and Failure Modes and Effects Analysis (FMEA) to assist service designers in designing a failure-free service system. In the proposed approach, a blueprint of a service system should be, first, developed to identify the potential fail points and failure modes for both front office and back office service activities. Based on the blueprint, the FMEA tool is then applied to prioritise the critical potential failure modes of the service system and take the required actions to ensure service design performance. An example of a hypermarket service system was used to demonstrate the proposed approach. The example not only identifies the most likely failure modes but also provides the effects and possible causes for each of the most critical failure modes. This implies that the actions to prevent these failures from occurring should be the main focus in the service design stage of the example company. Some managerial implications are also provided.     

Interest rate option pricing with volatility humps

This paper develops a simple model for pricing interest rate options when the volatility structure of forward rates is humped. Analytical solutions are developed for European claims and efficient algorithms exist for pricing American options. The interest rate claims are priced in the Heath-Jarrow-Morton paradigm, and hence incorporate full information on the term structure. The structure of volatilities is captured without using time varying parameters. As a result, the volatility structure is stationary. It is not possible to have all the above properties hold in a Heath Jarrow Morton model with a single state variable. It is shown that the full dynamics of the term structure is captured by a three state Markovian system. Caplet data is used to establish that the volatility hump is an important feature to capture. This revised version was published online in June 2006 with corrections to the Cover Date.     

The relationship between cultural values and learning preference: the impact of acculturation experiences upon East Asians

Globalization and technology advancement are creating more biculturalism at workplaces and learning settings. However, little is known about acculturation experience and its influence on a person's cultural values and learning preference. The research reported in this study investigates the impact of acculturation experiences upon the relationship between cultural values and learning preference of 292 Far East Asians (from Confucian‐influenced societies) and Asian Americans. Different preferences for learning methods and different levels of traditional cultural values were found between these two groups of adult learners. Acculturation experience was identified as the influential factor for the differences. However, they all still retain their traditional cultural values in various degrees regardless of the length of time the individual had been exposed to the acculturation experience. The impact of cultural values on an adult's learning preference is an area of concern in cross‐cultural training and development.

厚层砂岩顶板综采工作面初次放顶的安全技术研究

本文针对谢桥煤矿13318E厚层砂岩坚硬顶板工作面,首先提出了超前在工作面切眼顶板施工双排三花强制放顶爆破眼的技术方案。经过爆破,老顶形成了明显的裂隙,并且部分老顶矸石冒落高度达到0.6m。然后,通过在支架上布置自动检测压力表,研究了采动影响下的采场支架压力变化,并与老塘顶板跨冒、巷道围岩变形作对比分析,得到了初次放顶技术方案的可行性,为相类似条件的工作面初次放顶提供有益的技术参考。     

美国商品流通渠道的结构与变迁 --基于美国经济史的研究

本文通过对美国200余年经济史的考察,对美国商品流通渠道的结构与变迁过程进行了较为深入的研究。研究的初步结论是:美国商品流通渠道结构的演变过程是伴随着美国工业化过程进行的,商品流通渠道结构的演变是对工业化进程的回应;美国工业化过程中生产技术、体制的变化是商品流通渠道结构演变的基本动力。     

借款费用资本化问题浅议

企业提供的会计信息是否真实可靠、是否具有有用性,无论是对政府部门的宏观决策,还是对利益相关者的投融资决策,都具有非常重大的意义.而财政部颁布的一系列会计准则正是体现这一基本精神.其中,新的借款费用准则明确阐述了什么样的借款费用可以资本化、何时资本化、怎样资本化,与旧借款费用准则相比,在很多方面有所突破 ,并与国际会计准则日趋相同 .实际工作中应该如何运用这一准则是摆在我们面前的重要课题.
