Spatial analysis of the competitiveness of the high-speed train and air transport: The role of access to terminals in the Madrid–Barcelona corridor

This paper analyzes the effect of access and egress time to transport terminals over the spatial competiveness of the high-speed train (HST) in the Madrid–Barcelona (Spain) corridor, one of the densest airline domestic markets in the world. Applying spatial data from 2010 provided by a geographical information system (GIS) to a mode choice model estimated with sample travelers in this corridor, the present study examines whether and how the level-of-service of transport terminals spatially affects the competitiveness or modal distribution of HST and air transport in the provinces of Madrid and Barcelona; and, in particular, the degree of competitiveness that can be accrued by the access time provided by private car and transit in different market segments, especially mandatory and leisure trips. In a number of urban zones near train stations and airports, terminal accessibility clearly favors one transport mode in comparison to the other. Improving terminal accessibility via private car or public transit not only affects the relative access to terminals, but also represents a key strategy for readjusting the market shares of the competing modes in the corridor.     

Demand uncertainty and airport capacity choice

This study analyzes the effects of demand uncertainty on airport capacity choices. It shows that demand uncertainty will not change optimal capacity choice if demand variation is low and capacity cost is high; otherwise the optimal airport capacity under demand uncertainty will be larger than the case when a deterministic mean demand is considered. These conclusions are robust with respect to the different market structures considered in this study and hold for both profit-maximizing and welfare-maximizing airports. The moderating effects of commercial revenue, capital cost, and airport operation cost on airport capacity choice are qualitatively the same in the cases of uncertain demand and deterministic demand.     

港口工程造价的确定与控制

港口建设需要巨额的资金投入,其中大部分政府投资用于港口基础设施和航道的建设。为使基建资金能够发挥最大效用,创造最好的社会效益,需要对工程造价进行有效控制和管理,有效保障建设资金分配与使用的合理有序。水运工程造价确定与控制的重点在工程设计阶段,通过设计竞标选定最佳方案是工程设计阶段造价控制的有效手段之一。

结构失衡与政府体制改革

我国近期的这场宏观调控的直接动因是经济过热而导致了结构失衡。过度投资与各地的“圈地运动”则成为当前结构失衡的突出表现。国有企业陷于困境是结构失衡的又一深层次表现。国有企业的核心问题是政企不分，现有的政府制度使国有企业无法成为市场经济中的自主主体。在投资失控、“圈地”以及国有企业困境等问题背后都有政府特别是地方政府的影子。当前一系列突出矛盾与问题意味着经济改革的发展把政府体制改革提上了日程，而这一改革的核心问题是“务正业”，也就是说，政府必须退出市场经济中实际主体的角色，把市场主体的角色真正归还给企业，而管好政府该管的宏观经济环境培育与宏观调控工作。
