大湘西旅游业发展潜力模糊综合评价

旅游业是现代服务业中关联度很高、带动性极强的"龙头产业"和"朝阳产业",旅游业在发展过程中显示出来的巨大潜能使得我国很多地区将旅游业作为支柱产业来培育,区域间旅游竞争日趋激烈。然而,部分地区并没有对自身发展旅游业的未来前景作全面、科学地评价,就一厢情愿地将旅游业定为支柱产业,造成旅游资源的开发性破坏以及区域产业结构失调等灾难性后果。鉴于此,对于迅速发展的大湘西旅游业,文章在全面分析其影响因素的基础上,构建了大湘西旅游业发展潜力评价指标体系,运用模糊综合评价法得出大湘西旅游业发展潜力较好(V4级)的结论,并就大湘西旅游业的未来发展提出了政策建议。     

Evaluating the Tourism Potential of Public Museums in Hangzhou: A Supply-Side Perspective

This is a qualitative study to evaluate the tourism potential of public museums from a supply-side perspective. Nine specialized public museums in Hangzhou were evaluated based on six criteria: cultural, physical, product, experiential, marketing, and leadership. The overall tourism potential was rated as moderate for the museums in Hangzhou. Poor accessibility, isolation from tourism nodes, lack of complementarity with peripheral attractions, and limited carrying capacity impair the museums' appeal to tourists. The local government's proactive intention to develop cultural tourism and the innovative marketing efforts adopted by a few museums certainly help to enhance the museums' tourism potential.     

舟山群岛新区港口区位势评价及其发展战略研究——基于舟山、宁波、上海三港区位势的实证分析

舟山群岛新区是国务院继上海浦东新区、天津滨海新区和重庆两江新区之后批准设立的第四个国家级经济开发新区,港口物流功能的发挥是舟山群岛新区建设是否成功的重要标志.文章构造并运用港口区位势理论模型,量化分析舟山群岛新区港口及其主要竞争港口的区位势,模型结论显示了舟山群岛新区港口的相对能力以及在长三角区域港口物流体系的地位,并以此为依据提出舟山群岛新区港口发展思路及相应的保障措施.

中国吸引外资与对外投资：面临的问题及因应策略

为对我国对外投资和招商引资的现状进行全面的分析和把握,作者对比分析了我国对外投资流入和流出的规模及相关指数,并借助邓宁投资阶段理论分析了我国对外直接投资所处阶段。结果认为：我国的对外直接投资流出,无论是绝对规模还是相对规模都与FDI流入相差甚远,更与我国当前的经济发展水平不相符。因此,促进FDI流入和流出相互协调势在必行,为此需要切实把握我国FDI流入和流出现状,并以此为基础找到切实可行的措施。     

Assessment of business potential at retail sites: empirical findings from a US supermarket chain

We address the problem of estimating retail business potential at alternative sites, with concern for assessing performance relative to potential in existing markets and for identifying the best sites for expansion into new markets. At question is the utility of information typically used in formal retail patronage models, in comparison with additional information considered important by retail executives. Relevant data are gathered from secondary sources and intensive in-store surveys are conducted to produce a portfolio of information about neighbourhood demographics, store ambience, variety and quality of products and services, relative prices of selected products, etc. for stores in a retail grocery chain and competitive stores in the chain's markets. We experiment with alternative statistical models for store performance to determine the consequence of restricting the types of data available when constructing the models. Our findings suggest that while information about store location and surrounding areas, store characteristics and competitive position are all required to obtain the best assessment for business potential at a site, a few key variables on each dimension offer the bulk of explanatory power. Further, the spatial-locational variables affect all measures of store performance in intuitive directions, whereas the effects of other variables differ according to performance measure and reflect the store's market position.     

国内外市场潜力对FDI区位选择的影响研究

本文运用1996-2008年全国276个地级及以上城市和39个我国主要贸易伙伴的面板数据,通过估计固定效应模型,研究了我国城市面对的市场潜力对在华FDI区位选择的影响。为了估计各种市场潜力对FDI流量的不同影响,将市场潜力分为国内和国外市场潜力,并且将国内市场潜力分为省内和省外市场潜力。本文发现一个城市面对的国内市场潜力和国外市场潜力都对该城市吸收FDI具有显著的促进作用,而前者对FDI流量的影响更大。另外,一个城市面对的来自本省的市场潜力将正向影响该城市吸收外资,但来自外省的市场潜力却对该城市的FDI流入无显著影响,这反映了我国国内市场存在分割。     

我国汽车制造业的贸易流量与出口潜力:基于引力模型的分析

近年来,随着汽车工业的发展,汽车制造业出口呈现出快速增长的势头,在我国出口商品中所占的比重不断增加。本文选取了与我国汽车贸易往来最为密切的39个国家和地区,通过构建引力模型,对影响1 999年以来我国汽车制造业出口的主要因素进行了实证分析。在此基础上,对未来我国汽车制造业出口贸易的发展潜力进行了预测,并提出了我国汽车制造业出口持续发展的对策建议。

浅谈危险与可操作分析(HAZOP)在长输管道中的应用

长输管道是一个复杂的系统工程,具有点多、线长、输送压力高等特点,输送介质多为易燃、易爆、有毒、腐蚀的液体,一旦发生事故,将造成严重的环境污染和经济损失。因此,降低长输管道事故发生率是管道运营单位的首要任务。事实证明,危险与可操作性(HAZOP)分析是一种科学的、行之有效的方法,通过分析可能出现的工艺偏差和对危险源的辨识,将潜在危害消灭在萌芽状态,由事故调查与统计转变为事前预防,很大程度上提高了输油管道系统的安全性。本文论述了HAZOP的方法研究、结合实例探讨了HAZOP在输油管道行业中的应用以及HAZOP的发展前景。
