The hidden value of air transportation infrastructure

Air transportation is a key strategic asset in that it provides access to markets and thereby enables the economic development of nations. Thus, in order to maintain their competitiveness in a global economy, countries must invest in air transportation infrastructure to ensure their ability to meet current and future demand for aviation services. The objective of this paper is to develop and illustrate a methodology for evaluating the strategic value of air transportation infrastructure, in particular the benefits associated with the ability to react quickly to changes in the market. The hypothesis is that by recognizing and taking advantage of this strategic value, it may be possible to design better policies for aviation infrastructure delivery.The methodology developed here uses system dynamics to model different strategies for infrastructure delivery. These strategies are defined by three variables: the amount of capacity increase, the time to deliver the capacity and the congestion threshold that triggers the need for capacity delivery. Monte Carlo simulation is used to take into account multiple sources of uncertainty. The model shows that a strategy of capacity delivery based on small increments and short response times can yield more benefits than strategies that consider large capacity increases and long response times. Furthermore, in the specific airport example considered here, it was found that a congestion threshold of 75% should be the trigger for capacity enlargements if strategies based on small capacity increments and 1 or 5 years to increase capacity are considered. The lesson for decision-makers is that congestion delays must be addressed with foresight.     

关于我国财政政策导向调整的研究

近年来我国实施的积极财政政策确实在很大程度上促进了经济和社会的发展。但是随着经济市场化程度的不断提高和经济环境的变化，这种积极财政政策也表现出诸多的不适应性。因此应适时调整财政政策导向以适应经济和社会发展的新要求。拟从我国近年来实施的积极财政政策的成效分析出发，阐述了当前调整财政政策导向的必然性，并提出了今后我国财政政策的调整方向。     

机场净空区超高障碍物风险性分析

针对机场净空区超高障碍物较多的现象,对飞机飞行航迹进行了测试,提出了净空安全系数的概念,结合实际测试数据,应用统计分析原理,得出了净空安全系数的概率分布规律.以安全系数的分布规律为基础,对不同超高障碍物的风险性进行了分析,并提出了按照不同安全系数划分障碍物限制高度的思路,最后给出了不同类型机场净空安全系数的建议值,对各类机场净空管理和障碍物限制面的确定具有重要参考价值.

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.     

Managing academic innovation in Taiwan: Towards a ‘scientific-economic’ framework

Since the passage of the Science and Technology Basic Law in 1999, Taiwanese universities have taken a more “scientific-economic” approach to protect and commercialize their research. This research mainly examines innovation activities such as patenting, licensing, and incubated startups in the context of Taiwanese higher education institutions (HEIs). The “scientific-economic” framework used to analyze the strategic aspects influencing these academic innovations includes (1) intellectual property managerial capabilities, (2) the strength of external industrial partnerships, (3) the university entrepreneurial orientation, and (4) government research policy. Four hypotheses were developed. Data were collected via a questionnaire with all 122 HEIs in Taiwan surveyed.The research reveals that the aspects of intellectual property managerial capability, HEI-industry partnerships, and academic entrepreneurial orientation are useful to distinguish the university's innovation performance on patent grants, licensing incomes, and firm incubation. Also, government support on research plays a moderating role in academic innovation. Managerial and policy implications for managing innovation effectively in universities were drawn.     

中美水利投融资政策的比较

水利投融资政策是指在水利建设领域投资、融资、补偿等政策与法规的总称,按照投资主体结构及分工安排、融资渠道的开辟与规定以及投资补偿等可以分解成水利投资政策、水利融资政策、水利补偿政策三个部分,考察一国的水利投融资政策,可以从上述三个视角进行分析。由于水利投融资政策不仅决定着一个国家一定时期水利资金配置的结构与     

浅议物流信息商品化

随着中国入世和电子商务时代的到来，第三方物流市场需求巨大且发展迅速，国外物流企业开始抢占中国市场．对我国的第三方物流企业来说，就必须充分挖掘第三方物流中存在的潜在盈利点。而发生在物流过程中的各类信息也可作为第三方物流企业一个重要的利益来源，但长期以来都没有得到足够的重视，这将在很大程度上制约第三方物流企业的进一步发展，甚至增加整个社会的物流成本。本文试图把第三方物流企业信息商品化的可能性加以论述，并提出实际操作的初步构思。
