据最新统计数据,中国的社会物流总费用占中国GDP的18%,与发达国家相比要高出很多,对制造企业来说,物流成本甚至高达生产成本的30%-40%。我国物流成本居高不下,且物流供应链流通不畅,严重制约和影响着国民经济的发展。 相似文献

所谓一个国家的物流效率,是指社会物流成本与GDP的比率,这个比率越小,物流效率就越高。目前发达国家的物流效率平均在10%左右,而我国是18%,效率比发达国家几乎要低一半。两年前,国家"十大产业振兴规划"把物流业包括其中,让我们看到政府的眼光和决心,在此我们也呼吁各 相似文献

受国内外形势变化,以及经济下行压力的影响,2018年,我国物流业总体运行稳中趋缓,需求结构持续优化,消费品物流成为产业发展重要驱动力的同时,工业品物流则向价值链上游延伸。据中国物流与采购联合会统计显示,2018年全年社会物流总费用为13.3万亿元,同比增长9.8%,增速较上年提高0.7个百分点。社会物流总费用与GDP的比率为14.8%,较上年略有上升。同时,由于货源增速放缓和运输结构调整,全年运输费用明显回落。随着资本市场的发展,兼并重组正在成为物流企业补齐短板、跨越式发展的重要手段。物流互联网全面连接物流资源,推动物流"在线化"发展;越来越多的制造、商贸和物流企业加快向供应链转型发展。此外,物流基础设施建设的加速,以及简政减税降费政策的相继出台和逐步落地,促使行业营商环境持续改善,也让2018年成为行业高质量发展的一年。迈入2019年,物流业将面临怎样的新机遇与挑战?在新旧动能转换相互交织中,如何更好地实现"物流强国"之路? 相似文献

Pedestrians as compared to vehicular traffic enjoy a high degree freedom of movement even in heavily congested areas. Consequently, there are more alternative links available to pedestrians between a given origin‐destination (O‐D) pair. This paper describes a study done by the University of Calgary to evaluate the factors affecting the choice of route on intra‐CBD trips or trips within the Central Business District (CBD). An origin destination survey conducted in downtown Calgary, Alberta enabled the identification of the most significant factors influencing the choice. These factors were analyzed in relation to the physical characteristics of the location, personal characteristics of the trip maker and the type of the trip. It appears that most people chose the shortest link and factors such as the level of congestion, safety or visual attractions were only secondary. This suggests that the length should be made a major consideration when planning and designing pedestrian links. 相似文献

The main deficiency of most current modeling approaches to transportation can be identified as neglect of the integration of existing geographical knowledge in regard to the ex ante transport/land use modeling approaches, with its focus on territorial dynamics and theory development. This paper addresses this aspect of the problem by introducing a theoretical and methodological framework for the analysis of the interrelationship between land uses. The analysis attempts to determine to what extent the functional land use in a city can be considered an ordered pattern. The order sought does not rely on purely spatial configurations, but on the correlation of transportation and land use. The first section of this paper focuses on theoretical considerations. It stresses the fact that conventional approaches do not apply in the present context. It then suggests an alternative based on areas of influence and measured in terms of level of attractance of land uses. The second describes a procedure based on this alternative following the remarkable contribution of Hanjoul, Beguin and Thill. An application of this procedure to the analysis of Shanghai is then examined. Finally, an evaluation of the strategies for optimizing the interrelationship between land uses is presented. The paper concludes with a possible research agenda. 相似文献

The paper considers the possibility of quantitative analysis of behaviour, with particular reference to travel behaviour, from a methodological standpoint. The chief conclusion is that the nature of the subject implies that disaggregate statistical analysis is the most useful technique. The relationship of this methodology to theoretical issues is discussed, concluding that general theoretical issues are not susceptible to empirical resolution. The theoretical framework essential to analysis or forecasting of behaviour must therefore be established a priori The paper concludes with a discussion of the practical problems and achievements of disaggregate analysis. 相似文献

This paper estimates the efficiencies and productivity changes of 12 international airports in the Asia-Pacific region based on data from 1998 to 2006. We apply stochastic frontier analysis (SFA) to compute efficiency estimates and use the Malmquist productivity index (MPI) to analyze productivity changes. We use the SFA model with a translog-type production function after testing the statistical hypotheses. According to the results of the SFA hypothesis tests, airports have experienced a technological regression; the deviations from the efficiency frontier are caused more by technical inefficiency than random noise. However, the inefficiency was found to decrease. The MPI reveals a declining trend resulting more from technological change than from efficiency change, with a decrease in inefficiency. Taken together, both the hypothesis tests and the MPI not only provide consistent conclusions, but also suggest that airports should concentrate on technological progress. 相似文献
