Land rents and transport improvements: Some urban parables

Define a transportation improvement's impact zone as the area within which resident households and business firms regularly utilize the improvement. Three simple parables suggest that the increases in impact-zone land rents that usually accompany improvements do not accurately reflect its benefits. Seemingly modest variations in the demand and supply relationships that characterize impact-zone residents can have major effects on the relationship between benefits received and the land-rent changes that are measured. Generally speaking, increases in impact-zone land rents substantially understate benefits unless these benefits are small either absolutely (because the improvement is modest) or relatively (because the impact zone is part of a homogeneous area of much larger size).     

高速公路最佳收费标准的测算研究

长江口12.5 m深水航道运行初期的疏浚效益评价

构建疏浚货运比、疏浚单方经济效益2个相对指标,同时结合疏浚土的综合利用,评价长江口12.5 m深水航道运行初期的疏浚效益。结果表明:2011—2015年长江口深水航道疏浚货运比趋于下降,已由运行首年的1 083 m~3/万t降至2015年的765 m~3/万t,降幅近30%。近5年来,深水航道疏浚单方经济效益增加明显,2015年已达到142元/m~3,远高于目前国内疏浚费用单价。同时,用于滩涂围垦的航道疏浚土数量相当可观,有利于控制疏浚和造地成本,实现提高长江口疏浚土利用率和增加上海市土地资源战略储备量的双赢局面。当前长江口12.5 m深水航道已进入全面发挥效益的稳定运行阶段。     

长江口12.5 m深水航道运行5年沪苏两地的效益响应

选择上海市及江苏省2个地区作为长江口深水航道受益对象,从宏观经济效益和社会效益2个层面分析评价长江口12.5 m深水航道运行5年沪苏两地的效益响应。结果表明,沪苏两地沿江港口的疏浚吞吐比整体有所下降,近5年降幅分别近15%和25%,2015年已分别减小至949 m~3/万t和327 m~3/万t。2011—2015年,沪苏两地因12.5 m航道产生的疏浚单方GDP增长量分别为目前国内疏浚成本单价的15~20倍和40~60倍,疏浚净效益相当可观。随着12.5 m深水航道江苏段的投入运行和沿江港口码头的改造升级,长江口深水航道的疏浚效益还将进一步增加。     

A review of guidelines for including wider economic impacts in transport appraisal

In this paper we examine how 23 industrialised countries treat wider economic impacts (WEIs) in transport appraisals. We identify 12 different types of impacts based on these countries’ appraisal guidelines. Agglomeration impacts and Production changes in imperfect markets are the most widely accepted, being recognised by 14 and 10 countries, respectively. However, about half of the impacts are mentioned by only one country, and few recommend including the impacts directly in cost–benefit analyses. Several countries provide provisos or criteria that must be met before WEIs can be assessed in the first place. We found method recommendations for quantifying WEIs in 10 countries. However, with the exception of the UK Department for Transport’s (DfT) methodological framework, there is very little international consensus on the choice of appropriate methods. Our findings thus supplement and reinforce the conclusions from the Norwegian Official Report of the Hagen Committee [NOU 2012:16. (2012). Samfunnsøkonomiske analyser. Oslo: Departementenes servicesenter] that there is currently no established consensus on the magnitude and relevance of WEIs, or on how and which of these impacts should be taken into account in transport appraisals. Recommendations for further research and appraisal practices are provided.
