基于第二课堂的物流管理实践教学体系优化

实践教学对于大学生创新能力创新意识培养作用显著,然而物流管理专业实践教学尚不能很好实现上述目标。文中首先提出本科院校物流管理专业培养目标,进而指出实践教学的目标,然后详细指出实践教学的内容体系,阐述了各个模块的作用和教学方法,最后指出实践教学体系建设中一些需要注意的问题。     

第三方仓储物流企业盈利模式探讨

文中主要论述了第三方仓储物流企业三大类共四种不同类型的盈利模式,包括空间仓储服务模式、增值服务模式和基于供需管理平台的服务模式,其中基于供需管理平台的服务模式可分为作为初级阶段管理增值模式和高级阶段的供需网控模式。文中最后还提出了模式转换的建议措施。认为,前两种模式是过去和当前第三方仓储物流企业的主要盈利模式,后两种模式则代表着企业未来的发展方向。     

Price rigidity and market-clearing: a conceptual clarification

This article tests the view (derived from Hicks and Patinkin)that non-market clearance may be caused by slow adjustment (‘processrigidity’). There are models where market-rationing ispresent and derives from some form of rigidity, but this rigiditycannot be considered as process rigidity. It is similarly possibleto accommodate the idea of process rigidity within the Marshallianresearch programme. What is missing is that market-rationingmight be its corollary. The reason such a causal link is oftenbelieved to exist lies in a generic use of the concept of rigidity,used to designate alternative and incompatible phenomena: ‘exogenousend-state rigidity’ and ‘equilibrium end-state rigidity’,as well as process rigidity. It is true that these first twoforms of rigidity create market rationing. The belief that slowadjustment also generates market rationing results from theunwarranted extension to process rigidity of conclusions whichare only valid for the first two.     

Technical Efficiency of the Brazilian Municipalities: Correcting Nonparametric Frontier Measurements for Outliers

In this paper we estimate the DEA technical efficiency for 4796 Brazilian municipalities, by applying a recently proposed “Jackstrap” method, which combines Bootstrap and Jackknife resampling techniques, to reduce the effect of outliers and possible errors in the data set. We perform calculations to identify and eliminate high leverage municipalities, using different variants of Data Envelopment Analysis (DEA), as well as Free Disposal Hull (FDH). Corroborating previous results, efficiency results for the Brazilian municipalities show a clear relationship between the size of the municipality and its efficiency scores. Indeed, under both DEA variants, smaller cities tend to be less efficient than larger ones hence indicating that the quality of the frontier adjustment improves significantly as the size of the municipality increases. We present arguments that may explain to some extent these findings, such as economies of scale and the excess spending due to revenue from royalties. However, such effects require further, more careful examination.

Extending the SAM with Social and Environmental Indicators: An Application to Bolivia

Extending economic accounts with sets of social and environmental indicators is a first step towards a more integrated analysis of aspects of sustainability problems. In this article, therefore, a proposal is made to nest social and environmental indicators into an existing economic accounting framework. The Social Accounting Matrix (SAM) is taken as a basis, because of its flexibility regarding extensions with non-monetary data addressing social and environmental concerns. The main thrust of the paper is methodological. From the discussion of methodological issues and the application to the SAM for Bolivia for the year 1989, it is concluded that it is, in principle, feasible and relatively simple to extend the SAM with the two sets of indicators. However, additional data will have to be collected to be able to address, more adequately, the problems of sustainability.     

均衡性转移支付、公共支出结构与经济高质量发展

本文首先从理论层面系统阐述均衡性转移支付、公共支出结构与经济增长质量三者之间的多重作用机制。其次立足"五大发展理念"构建综合指标体系对经济增长质量展开测度,本文发现我国地方经济增长质量虽然在整体上呈缓慢上升态势,但其绝对水平相对偏低,且具有较为明显的地区异质性。最后本文通过构建动态面板联立方程模型与采取三阶段最小二乘法进行实证考察,结果表明:地方政府公共支出结构与经济增长质量显著正相关,但均衡性转移支付与经济增长质量的正相关关系并不显著。标准化回归结果显示均衡性转移支付能够通过优化公共支出结构对地方经济增长质量产生间接提升效应。     

中国制造业贸易模式变迁的工资差距效应

本文利用中国制造业27个细分行业的面板数据,采用固定效应不变系数的静态面板模型,考察了我国制造业从产业间贸易向产业内贸易的变迁对行业间工资差距的影响及其传导机制。研究结果表明：（1）在制造业贸易模式的变迁中,出口扩大了行业间工资差距,而进口缩小了行业间工资差距。（2）制造业贸易模式变迁主要通过价格机制扩大了行业间的工资差距,而技术机制和个体机制的影响则不显著。     

Testing the Influence of Substitute Sites in Nature Valuation by Using Spatial Discounting Factors

This paper investigates the effect of nearby nature substitute sites on preferences for nature restoration. Contrary to prior studies, we use a respondent-centric approach to control for substitute sites. We assess each respondent-specific spatial context by computing densities of nature substitute sites within various ranges from each respondent’s home. This approach considers the use and non-use values of nature together. Data from three similar discrete choice experiments carried out in Flanders (Belgium) are compared. Different spatial discounting factors are tested to explore how the substitution effect behaves with regard to distance. Latent class analyses are performed to account for preference heterogeneity among respondents. We observe divergent behaviours across groups of respondents. The “distance-to-substitutes” affects how respondents gauge substitute sites. We find a significant influence of the squared average buffer distance but this effect varies in sign across case studies and classes of respondents. Our results demonstrate that individual-specific GIS data can significantly improve the representation of the spatial context and the transferability of value functions. However, the roles played by preference heterogeneity and nature perception on respondents’ capacity to value nature still deserves further attention in future research.     

What hinders innovation performance of services and manufacturing firms in Mexico?

Barriers to innovation are heterogeneous, of financial and non-financial nature. The importance of barriers to innovation and their actual influence on innovation depend on firms’ characteristics such as sectoral affiliation, technological behavior and their response to perceived obstacles to innovation. Firms either continue to engage in innovation, or they avoid the activity altogether. This paper explored the nature and perceived importance of the obstacles to innovation that firms confront, in a developing-country context; we build on survey data about firms in Mexico. Our findings suggest that two kinds of policy interventions should help offset a firm’s perception of barriers to innovation. On the one hand, policies should enhance the innovation capacity of firms interested in innovation; on the other hand, policies need to tackle factors that reduce the interest of firms in innovation. Policies that boost demand for locally generated innovations would assist in achieving both these goals.
