Transport in regional science: The “death of distance” is premature

Transport costs have always been an important dimension in regional science. It is therefore remarkable that regional science and transport economics have developed in a rather unconnected way. Although being distinct, the routes of the two were parallel, and there are signs that the two fields will get closer to each other. This paper further discusses long run trends in transport costs and the potential spatial consequences. The main conclusion is that although in terms of money and time, the performance of transport has improved enormously, many economic activities have not become footloose to the extent as expressed by the notion of death of distance. One of the reasons discussed is the role of transaction costs, some being clearly related with distance.JEL Classification: R0, R4The authors thank the guest-editors and an anonymous referee for helpful comments.

Consistent boundary conditions for flows within the atmospheric boundary layer

In computational wind engineering the neutrally stable atmospheric boundary layer (ABL) is often simulated using the standard k-ε model. The application of boundary conditions that are inconsistent with the profiles used at the inflow boundary causes streamwise gradients in the solution and prevents the simulation of a horizontally homogeneous boundary layer. In the present work these problems are overcome by applying a simple extension of the shear stress boundary condition at the top of the domain and by using one-dimensional models to generate inflow profiles in equilibrium with the ground boundary condition. This procedure allows the impact of the inconsistent boundary conditions to be quantitatively assessed. It is shown that inconsistent boundary conditions at the top of the domain result in erroneous streamwise gradients throughout the domain. These errors are reduced by enlarging the domain in the vertical direction but are not removed. The errors are also found in simulations with idealised and real topography included in the domain. A brief discussion of the impact of the errors on simulations of wind energy projects is given.     

建筑形式化之原因初探

长期的封建专制制度造成科学和民主精神的缺乏,是建筑设计失去创造性的根本原因。殖民主义和后殖民主义的历史影响难以在短时间内消除,崇洋、尚洋的心理使建筑设计停留在形式的摹仿。本文从历史文化角度,分析这两方面对中国社会产生的负面影响出发,阐述建筑设计缺乏创造性的历史渊源。     

业主支付担保制度解决工程款拖欠的博弈论分析

近年来,我国工程建设领域业主拖欠工程款现象凸显.本文利用经济学原理,研究了工程业主违约欠款的内在动机和实行业主支付担保制度能够解决工程款拖欠的机理,为我国推行业主支付担保提供理论依据.     

建筑艺术与科学的比较研究

本文通过对建筑艺术与科学在成就、社会文化中的地位、评判方式及时间感等方面的比较研究,阐明了两者之间的异相,并指出中国当代建筑理论的发展方向是加强科学理性的基础研究。     

国际工程管理中索赔的博弈分析

在国际工程的项目管理工作中,索赔管理是承包商保护利益的行为和减少损失的必要手段,也是承包商综合管理能力的具体体现。本文构建了一个完全信息动态博弈模型,通过逆向归纳法解得两类索赔成本支付方式下七种收益的纳什均衡解,说明索赔对于合同双方,尤其是承包商的重要性,并讨论了索赔过程中需要注意的问题。     

基于三方博弈的工程总承包模式推广策略研究

构建基于三方博弈的工程总承包模式推广模型,分析模型演化的路径和稳定策略,并通过Matlab仿真模拟来验证模型的有效性。研究表明,政府行为策略选择是决定博弈模型演化路径的关键因素。现实条件下,企业和业主均不会主动选择工程总承包模式,需要政府通过完善市场机制、增加财政补贴和推广全过程工程咨询等策略来提高企业和业主的综合收益以推广工程总承包。
