基于DEA模型的我国物流业效率评价研究

有效评价城市物流效率是科学配置和规划城市物流资源的基础。选取2004-2013年我国物流总产值作为研究样本,以等级公路里程、固定资产投资和物流从业人数作为输入指标,以货运量、货物周转量作为输出指标,构建我国物流业的效率评价模型,对综合技术效率、纯技术效率、规模效率三个方面进行综合评价。结果发现：近年来,公司的整体效率虽然有所提高,但仍然偏低,物流业的经营管理效率有待提高。最后给出相关的政策建议。     

基于广义DEA方法的矿产资源开发利用效率研究

为了矿产资源开发利用效率的提高,应该针对不同区域的特点采取有针对性的政策.借鉴广义DEA方法使用样本单元为参照标准对决策单元的效率进行评价的手段,对河北省各地市矿业开发利用效率进行分析.并在此基础上进行效率排序,为有针对性的矿业开发政策提供参考.     

Nonparametric Evaluation of Economies of Scope in the Context of Technical Efficiency: The Case of Rice and Vegetable Farms in Korea

This paper provides a nonparametric evaluation of economies of scope in the context of technical efficiency allowing for non‐convexity, with an application to Korean rice and vegetable farms. Relying on non‐parametric‐free disposal hull and data envelopment analysis approaches and input–output data for rice and vegetable farms from the Korea Farm Household Economy Survey data collected in 2007, this article examines technical inefficiency and its decomposition under non‐convexity and convexity. Empirical measures of technical inefficiency and its decomposition results are provided, with a focus on a component of technical inefficiency associated with economies of scope (i.e. diversification benefits) under non‐convexity in production technology. The decomposition measures of technical inefficiency include pure technical inefficiency, size inefficiency and diversification inefficiency. The results provide empirical evidence supporting size‐dependent diversification strategies, where benefits of diversification are larger for small farms on average compared to those of large farms.     

天津市创新资源配置效率评价

建立了天津市创新资源配置效率评价指标体系,采用DEA分析方法对2006年以来天津市创新资源的配置效率进行了评价,得出结论,2006-2013年中有五年呈现出资源配置最优状态,其余三年则存在投入冗余或产出不足,根据评价结果给出了投入冗余的缩减量和产出的增加量,为提出提高创新资源配置效率的对策措施提供参考。     

工业智能化对社会经济发展影响的研究趋势

作为第四次工业革命的核心,工业智能化将对社会生产产生颠覆性影响。在全球经济形势不断收紧的当下,世界主要国家不断加大智能生产设备研发投入,旨在通过智能革命实现经济新一轮跃升。对于发展中的中国而言,加速推动工业智能化改造是快速实现经济发展高质量转型,抢占经济发展先机,实现经济赶超的重要途径。在综合梳理工业智能化相关研究文献的基础上,从工业智能化引致的生产效率、劳动就业、收入分配以及产业结构变动出发,系统梳理工业智能化相关研究综述,在此基础上总结当前工业智能化相关研究的不足,并进一步分析该领域可拓展的研究方向。     

零售企业的物流模式及其影响因素研究

本文以零售企业的物流活动作为研究对象,通过实地走访调查和案例分析,研究了零售企业在中国目前条件下所采用的物流模式,以及影响零售企业选择物流模式的主要因素。调查与分析结果显示:第一,在目前的零售物流中,供应商主导的物流模式占居主导地位,而其中又以M12(供应商→零售商→消费者)最为普遍;第二,被调查的大部分零售企业使用了两种以上的物流模式,其中一种是主要的,其他则是辅助的;第三,即使采用相同的物流模式,各个企业的具体操作方法也有很多不同。第四,一些因素(如供应商的规模与实力、物流成本、产品特点和环境条件)被普遍认为对零售企业选择物流模式有影响,而另外一些因素(如零售企业的规模和实力、物流对零售企业成功的影响程度、零售企业的经营组织形式和业态等)则只被个别企业认为对其选择物流模式有影响。本文最后对这些结果的意义进行了讨论。     

The Effects of Process and Content Facilitation Restrictiveness on GSS-Mediated Collaborative Learning

Group Support Systems (GSS) technology, extensively applied in decision-making contexts, is now seeing increased application in the educational sector. Previous work has suggested that GSS applications can have significant positive effects on both the process and the outcome of collaborative learning. This study extends this work to examine the effects of process (high/low) and content (high/low) facilitation restrictiveness on GSS-supported collaborative learning. Our results indicate that content facilitation restrictiveness has no significant bearing on student learning. Process facilitation restrictiveness, on the other hand, is more influential, with knowledge acquisition by students requiring a low restrictive environment.     

组织系统再造的分析框架及逻辑拓展

通过对组织理论两个范式的关联分析,初步提出组织系统再造的理论命题,在组织价值再造与工具再造统一的分析框架下,整体刻画了一个组织系统再造的逻辑拓展模型。价值再造与组织学习是一种理性的融合与发展,实际是对于"第五项修炼"学习模型的逻辑拓展与价值发掘;工具再造则是关于BPR工具模式的优化升级,即一个从价值链至集成供应链直至价值网构建所描述的逻辑拓展过程。     

Are Small Firms Really Less Productive?

Small and medium-sized establishments (SMEs) account for a large proportion of industrial employment and production in almost all countries. Moreover, the recent literature emphasizes the role SMEs play in nurturing entrepreneurship and generating new products and processes. Although SMEs could be a source of new ideas and innovations, there are substantial productivity differences between small and large establishments. In this paper, we analyze three sources of productivity differentials: technical efficiency, returns to scale, and technical change. Our analysis on the creation, survival, and growth of new establishments in Turkish manufacturing industries in the period 1987–1997 shows that all these three factors play a very important role in determining the survival probability and growth prospects of new establishments.
