泛亚铁路资本运作方式探索

泛亚铁路有东线、西线、中线三种方案,每种方案的国际资本构成将会各不相同;中国在每种方案里的投资策略也各不相同;泛亚铁路工程的中国资本运作方式有多种,其中值得重视的有向泛亚铁路股份有限公司投资入股、BOT投资方式、逆向BOT投资方式、给予沿线有关国家以国家贷款(以泛亚铁路的收益为担保)等;泛亚铁路工程资本运作应重点解决为各类投资主体提供必要国家保护、予以适当外汇管理优惠和税收优惠等问题;良好的泛亚铁路工程资本运作将使东盟——中国自由贸易区17亿人民从中受惠.     

集聚经济视角下轨道交通投资对城市系统均衡的影响

随着城镇化进程加快,城市规模增加所带来的集聚效应和交通拥堵等负外部性之间的矛盾越来越突出,优化城市交通基础设施建设是缓解该矛盾的重要举措。本文同时考虑了集聚经济和交通拥挤两种外部性,构建并求解了一个两区域城市空间结构模型,分三种情况探究了轨道交通的投资引入和道路容量的优化对城市规模和城市空间结构均衡的影响。结果表明,轨道交通的投资引入能够增加城市人口规模和社会福利,使城市结构更加紧凑。但是,随着集聚经济水平的提高,城市规划者应逐步完善公交配套设施,以降低公交拥挤成本,提高公交出行分担率;还应制定相应的福利政策,避免由于个体效用下降而导致人口流出。     

Disaster prevention and strategic investment for multiple ports in a region: cooperation or not

With the growth of maritime transportation, seaports have become critical to the world economy as linking nodes between shipping and inland transport. However, the port system is fragile under certain unconventional emergency events. This study addresses the issue of investment on disaster prevention within the port competition context. The present model discusses and compares four situations of different relationships and strategies of pre-disaster prevention between two adjacent ports. Results indicate that both ports increase the disaster prevention investment under the cooperation scenario compared with that in the case of non-cooperation wherein they are complementary ports. Meanwhile, a numerical simulation is conducted to examine the collective and individual rationality of both ports. Although cooperation strategy decreases the total risk cost of two ports, one of the two ports may profit, whereas the other may suffer losses.     

Exploring active transportation investments and associated benefits for municipal budgets: a scoping review

Municipalities play an important role in the planning and development of communities that support active transportation (AT), which refers to human-powered modes of travel, such as walking and cycling. Municipal-level stakeholders involved in land-use and transportation infrastructure planning consider multiple social, environmental and economic considerations to inform decision-making and investments in AT. Evidence around the fiscal benefits of AT investment for local governments has not been systematically identified. This scoping review sought to explore the existing evidence regarding investments in AT and opportunities for savings on municipal expenditures and revenue generation. In total, 7060 records were located and screened; of which 162 full-text articles were reviewed. Ultimately, 23 articles met our inclusion criteria and were included in this review. The available evidence focuses on potential economic benefits of AT in the areas of tax revenues, property values, consumer spending and employment, all of which are relevant sources of revenue generation in municipal operating budgets. An evidence gap was identified regarding AT infrastructure investments and benefits corresponding to municipal expenditures (e.g. maintenance cost savings). Notably, a large portion of literature was published after 2009, suggesting that municipal-level evidence on the fiscal benefits of AT investments may just be emerging.     

CIM模型在高速公路投资风险评估中的应用

在分析、识别高速公路投资风险的基础上,建立了高速公路投资风险评估指标体系.针对风险因素具有结构多层次、因素多方面、评估模糊性、出现随机性、直接量化困难等特点,基于模糊理论,结合层次分析法,建立了控制区间和记忆(CIM)模型对高速公路投资风险进行评估.通过控制区间和记忆模型在工程实践中的应用,验证了CIM综合评估法在风险评估中的有效性和可操作性.     

新冠肺炎疫情对交通运输行业的影响及政策建议
