公路工程合理投标报价的制定

投标报价是投标成败最为关键的工作环节,投标报价是在初步预算标价的基础上,综合各方面的因素后确定的最终投标价格。主要探讨公路工程投标中如何确定一个低而适度的合理报价,既能争取中标且中标后又能获得理想的经济效益。     

需求弹性理论在铁路运价调整中的应用

在市场经济条件下,合理调节和运用价格因素,是运输企业提升竞争优势,把握市场竞争力的关键,常用的定价方法主要以运输价值为理论依据,该理论较少考虑市场机制作用下运输需求变动对运价的影响,难以适应短期价格决策.根据经济学弹性理论,提出了运输价格调整过程中的调价方向、调价幅度的确定方法,并给出了具体算例.     

Fuel price elasticities for single-unit truck operations in the United States

This paper provides fuel price elasticity estimates for single-unit truck activity, where single-unit trucks are defined as vehicles on a single frame with either (1) at least two axles and six tires; or (2) a gross vehicle weight greater than 10,000 lb. Using data from 1980 to 2012, this paper applies first-difference and error correction models and finds that single-unit truck activity is sensitive to certain macroeconomic and infrastructure factors (gross domestic product, lane miles expansion, and housing construction), but is not sensitive to diesel fuel prices. These results suggest that fuel price elasticities of single unit truck activity are inelastic. These results may be used by policymakers in considering policies that have a direct impact on fuel prices, or policies whose effects may be equivalent to fuel price adjustments.     

企业并购中的目标企业核心竞争力评估

目前在并购中,并购双方以各自核心竞争力优势为基础进行战略并购,以便达到优势互补,实现企业的持久竞争优势。因此,在目标企业评估中,目标企业核心竞争力的评估应受到重视,其内容主要包括技术创新能力和组织管理能力等方面。目前,我国对目标企业核心竞争力评估还不够重视,处于初级阶段。针对这种情况,对我国目标企业核心竞争力评估应从完善资本市场,使并购双方拥有更多自主权;通过产权制度改革将国有企业培育成合格的市场主体等方面入手采取相应对策。     

多方综合效益最大化的社会公共停车场停车收费定价方法

为了保障社会公共停车场后期的顺利投资与经营, 提出了多方综合效益最大化的停车收费定价方法; 考虑了停车者、投资经营者与社会公众的利益与需求, 利用停车特性调查数据分析、成本-收益停车定价模型和点弹性系数模型分别求出停车容忍费率、平均停车费率和最大社会效益停车费率, 分析了停车费用的定价方式, 制定了停车收费方案的合理构成和调整方法, 对比了现有停车定价方法与该停车定价方法对投资与经营效益的不同影响; 研究了后续时段停车费率单因素和3因素敏感性, 建立了后续时段停车费率与3因素之间的关系模型, 分析了3因素不同范围内的组合取值对停车收费方案的影响。分析结果表明: 后续时段停车费率是停车收费方案拟定的关键要素; 投资回收期、商业面积比例和停车场容积率在[-30%, 30%]内变动时, 后续时段停车费率的变化幅度将达到[-50%, 50%]; 控制商业面积比例和停车场容积率变动幅度在[-10%, 10%]内时, 投资回收期不宜取太长; 控制投资回收期和停车场容积率变动幅度在[-10%, 10%]内时, 商业面积比例不宜取太小, 最适宜比例为30%;控制投资回收期和商业面积比例变动幅度在[-10%, 10%]内时, 停车场容积率的取值对后续时段的停车费率影响不大。     

The residential parking rent price elasticity of car ownership in Japan

By using household-level micro data captured through the National Survey of Family Income and Expenditure for 2004, this study evaluates the residential parking rent price elasticity of car ownership in Japan. It analyzes the number of cars owned by a household, using various attributes including expenditure for renting a parking space on a monthly basis. The estimation results derived from the IV-ordered probit model show that the absolute value of parking rent price elasticity of car ownership is, at most, 0.48, which is fairly small (i.e., inelastic). The elasticity value varies depending on city size; for megacities, elasticity is always negative for car ownership, whereas for middle-sized or small cities, towns, and villages, elasticity is positive for one-car ownership and negative for the ownership of more than one car. Hence, when the price of parking increases, some people may switch from more than one car to one car and some people in megacities may switch from one to zero cars. Indeed, the net effect of a price increase may be that non-car ownership increases in megacities and one-car ownership increases in other cities.

Exploring vessel-price dynamics: the case of the dry bulk market

We investigate second-hand vessel price heterogeneity. Based on a sample of 5,591 purchase and sale transactions in the dry bulk sector over the period 1998–2016, we deploy a nonparametric regression technique to assess the determinants of vessel price and vessel price variability. Next, we use quantile regression to estimate the effect of regressors (sources of heterogeneity) at different parts of the vessel price distribution. We find evidence that main sources of vessel price heterogeneity are the age of the ship (the older the vessel the higher its maintenance cost), the 3-month LIBOR (reflecting the cost of financing) and the annual charter rate (revenues from operation). Their influence is stronger at all higher quantiles (periods of expansion) and the median of the vessel price distribution.
