The Performance of Service Industries in Canada: A Real Value Analysis

The performance of service industries in Canada has been lower than that of good industries over the last four decades, with noticeable exceptions such as for railways and telecommunication carriers. Service industries were less economically (and technically) efficient in that they generated less output value (quantity) per hour worked (level and growth) or per combined unit of labour and capital (multifactor productivity growth) than good industries. The relative output price of services declined slightly over time compared with goods. At the disaggregated level, changing relative output prices were substantial and proved to be an important factor explaining the relative satisfactory economic performance of many service industries despite their low technical performance. Nevertheless, the output share of service industries increased over that period, sustained, mainly, by the growing recourse of all firms to outsourcing of services.

Industry specific effects in investment performance and valuation of firms

A necessary criterion for a performance measure in corporate governance is the degree to which it mirrors how well the management succeeds in maximizing firm value. Such a performance measure is marginal q which links changes in firm value to the investments undertaken by the management. Empirical studies of investment and performance based on marginal q have demonstrated the usefulness of this measure. Most research however, has mainly focused on long-term performance. This paper takes a short-term perspective and, based on the marginal q-theory, considers how firms’ market values change in the extreme stock price cycle of a stock market bubble. Using a data set of listed Swedish corporations we find an anomaly in form of a new industry specific effect that, in addition to investment, explains changes in firm value.

我国金融发展对国际贸易的影响机理阐释及经验证据

在传统贸易比较优势逐渐丧失的背景下,实现外贸可持续发展战略给金融业提出了更高的要求,正确认识我国金融发展对外贸的作用机理和效应有助于相应的政策调适。本文的理论分析表明:金融发展主要通过金融制度、技术创新、资源配置、分散风险和汇率调整等途径来影响国际贸易;经验分析表明经济货币化、经济金融化、汇率贬值因素都对我国外贸发展起到了重要的促进作用,而经济证券化因素则不然。从静态的角度来看,经济证券化因素并没有促进我国外贸的发展,但从动态的角度来看,经济证券化因素仍会对我国外贸产生积极的影响。     

白洋港铁水联运车船直取模式研究

白洋港作为长江三峡的核心内陆港,是工业输出港、翻坝转运港和西部出海港,主要服务于白洋工业园区,担当西北地区物流陆水联运的作用。为实现白洋港铁水联运的无缝衔接,在阐述白洋港铁水联运模式及作业流程的基础上,针对白洋港既有铁水联运模式存在的问题,提出白洋港铁水联运车船直取模式,从车船直取模式设施布局及作业流程进行分析,达到压缩无效作业时间、提高白洋港铁水联运效率、释放技术站作业能力等效果,实现白洋港铁水联运效率的提升。     

我国铁路基础设施噪声的边际成本定价方法研究

通过概述国内外学者关于运输外部性内部化政策、运输外部性评估、运输外部成本计算方法等方面的研究成果,阐述了美国及欧盟寻求实现运输外部成本内部化的政策和方法。针对我国铁路基础设施噪声污染问题,在分析铁路噪声的产生、传播及估算的基础上,研究提出利用边际成本定价方法计算铁路噪声边际成本。噪声定价方法还有支付意愿法、冲击路径法等,这些定价方法及其实证量化还有待进一步深入研究。     

补贴介入下军工企业研发助力的“迷失”

研发投入与财政补贴是影响企业成长的内在因素和外在条件。选取我国军工上市企业2011-2017年面板数据,运用系统广义矩估计方法实证分析研发投入及财政补贴调节效应下研发投入与企业成长的内在联系。结果发现,研发投入强度对我国军工企业成长具有显著滞后性推动作用;在财政补贴调节效应下,研发投入对企业成长的激励作用有所“迷失”。研究结论为我国军工上市企业研发活动影响企业成长提供了新证据,为研究军工企业研发活动投入经济后果及如何适应军民融合进程拓展了新视角。
