乡村休闲旅游地游客满意度评价研究——以成都市三圣乡幸福梅林为例

以成都市三圣乡幸福梅林为例，研究乡村休闲旅游地的游客满意度评价。研究表明，游客在评价总体满意度时，游客的总体期望差异与总体满意度有较大的相关性，而目的地与游客最佳目的地、其他同类目的地的比较优劣与总体满意度的相关性小；在评价具体评价因子时，游客的期望并不清晰，对具体评价因子感知实绩与满意度的评价差异不显著，感知实绩能有效地反映游客的满意度；游客满意度不仅与游客的推荐意愿正相关，而且也与游客的重游意愿正相关。     

中国地区间财力差异的度量及分解

首先采用以人口为权数的加权变异系数对地区间财力差异进行了度量.随后提出财力的初次分配和再分配的概念,检验了财力的初次分配中不同财政收入项目及财力的再分配中不同转移支付项目对财力不平等的贡献率.认为对财力差异起主要作用的是财力的初次分配即财政收入,起次要作用的是财力的再分配即中央转移支付,其中,将营业税划归地方税、税收返还等保持既得利益的转移支付是造成地区间财力差异的主要原因,并且随着经济的发展这将导致地区差距的进一步扩大.     

Terrorism and its impact on economic growth and technological innovation

Recent terrorist acts, in particular the 9-11 attacks in 2001, have created disruptions in the global economy. The short-term impact had been felt in the global tourism, airline industries, as well as the financial markets. While the global economy has recovered and is adjusting to the new global realities, the longer-term impact of heightened security risk across the world can be felt in the form of higher risk premiums in asset markets, as well as a shift of resources towards dealing with terrorism. Just as World War II had accelerated the development of nuclear energy as well as a major contributing factor in the genesis of Silicon Valley, the current war against terrorism will affect both the pace and trajectory of technology trends, as efforts are focused on developing technologies to combat terrorism. In this paper, we review the effects of the current war on terrorism in terms of its impact on the economy, the allocation of resources to R&D, and the trajectory of future R&D.     

构建和谐社会必须努力缩小城乡收入差距

城乡收入差距加大是目前人们普遍关注的热点问题之一,也是实践中亟待解决的突出问题。在市场经济条件下,市场竞争的结果必然会扩大收入差距,导致两极分化。因而政府应通过政策的制定来消除中国的城乡差距,这对于推动经济增长,构建和谐社会有着重要意义。     

The future of hydrogen fueling systems for transportation: An application of perspective-based scenario analysis using the analytic hierarchy process

This paper integrates the analytic hierarchy process (AHP) with scenario analysis techniques to explore the commercialization of future hydrogen fuel processor technologies. AHP is a multi-attribute decision analysis tool useful for evaluating decisions with multiple criteria and alternatives. In this paper, AHP is extended using a technique called perspective-based scenario analysis (PBSA). In PBSA, scenario analysis is conducted based on potential future decision-maker perspectives that are integrated into the AHP framework. This paper discusses this method and applies it to the evaluation of hydrogen fuel processor technologies 15–20 years hence. The results provide an added layer of insight into the opportunities and barriers for the commercialization of these technologies as well as the methodological opportunities for using AHP and PBSA as a futures tool.     

基于DEMATEL方法的新兴技术产业化融资影响因素实证研究

新兴技术是提高国家产业竞争力的重要载体，但是资金问题一直是制约我国新兴技术产业化的瓶颈之一。构建新兴技术产业化融资影响因素理论模型，运用DEMATEL方法，实证检验不同因素对新兴技术产业化融资的影响程度。研究表明：融资扶持政策、资金渠道可选择性、共享信息有效性等因素对新兴技术产业化融资具有显著直接影响；资金供求匹配性、融资产品创新、信息共享方式等因素易受到其它微观因素影响，对产业化融资具有显著间接影响；担保费用、配套服务综合性及配套服务专业性等因素对产业化融资同时具有显著的直接与间接影响。据此，提出新兴技术产业化融资对策建议。

A substitution orbit model of competitive innovations

Successful innovation and diffusion of technology can be attributed to the identification of the orbit of emerging new technologies that complement or substitute for existing technologies. This dynamism resembles the co-evolution process in an ecosystem. In an ecosystem, in order to maintain sustainable development, the complex interplay between competition and cooperation, typically observed in predator-prey systems, create a sophisticated balance. Given that an ecosystem can be used as a masterpiece system, this sophisticated balance can provide suggestive ideas for identifying an optimal orbit of competitive innovations with complement or substitution dynamism.Prompted by such a sophisticated balance in an ecosystem, this paper analyzes the optimal orbit of competitive innovations and, on the basis of an application of Lotka-Volterra equations, it reviews substitution orbits of Japan's monochrome to color TV system, fixed telephones to cellular telephones, cellular telephones to mobile Internet access service, and analog to digital TV broadcasting. On the basis of substitution orbits analyses, it attempts to extract suggestions supportive to identifying an optimal policy option in a complex orbit leading to expected orbit.Key findings include policy options that are effective in controlling parameters for Lotka-Volterra equations leading to expected orbit.
