HOW CAN WE CALL TRANSPORT A UTILITY?

First railways, then buses and taxis and, for a time, road freight – there has for many years been a tendency to treat transport as a utility, and nowhere more so than in the provision of roads. This article calls for the return of all forms of inland surface transport to the market.     

The rise of 3-D printing: The advantages of additive manufacturing over traditional manufacturing

The use of additive manufacturing technologies in different industries has increased substantially during the past years. Henry Ford introduced the moving assembly line that enabled mass production of identical products in the 20^th century. Currently, additive manufacturing enables and facilitates production of moderate to mass quantities of products that can be customized individually. Additive manufacturing technologies are opening new opportunities in terms of production paradigm and manufacturing possibilities. Manufacturing lead times will be reduced substantially, new designs will have shorter time to market, and customer demand will be met more quickly. This article identifies additive manufacturing implementation challenges, highlights its evolving technologies and trends and their impact on the world of tomorrow, discusses its advantages over traditional manufacturing, explores its impact on the supply chain, and investigates its transformative potential and impact on various industry segments.     

北京：人口剧增背景下的房价综合治理

北京市人口呈现爆炸式增长,有观点认为应放任房价上涨以此解决人口问题。本文从分析北京市近年来人口变动情况及北京市房价现状入手,分析“高房价抑制人口增长论”,提出解决人口剧增的根本性办法是加快城乡统筹,从宏观层面予以解决。在北京市人口剧增的背景下,北京房价的调控措施应该包括坚持限购政策、开征房产税、加大保障性住房建设、打击市场上垄断投机、骗购骗租等不良行为。     

Interplay between reputation and growth: the source,role and audience of reputation of rapid growth technology-based SMEs

Abstract

Drawing on resource-based view and signalling theory, this paper presents a comparative case of four (young vs. old; small vs. medium-sized) business-to-business firms to examine how (i.e. through which sources), why (i.e. for which managerial purposes) and for whom (i.e. for which audiences) do technology-based small and medium-sized enterprises build their reputation along the process of rapid growth? The results indicate that in the pre-growth stage product awards as well as technological and financial partners are important sources of reputation for demonstrating technological capabilities and firm sustainability to potential customers especially for young firms. Older firms, in turn, rely on technology partners and acquisitions in the rapid growth stage to convince existing customers that the firms’ can keep up with their customer’s changing needs. Moreover, the reputation gained from the first well-known customer and a focused clientele appear to be two critical antecedents of rapid growth whereas patents do not seem to have a significant reputational role in rapid growth. Our study informs the theory of reputation development of growing technology-based firms by abstracting a more nuanced understanding of stakeholder- and stage-contingent reputation that fosters rapid growth, and provides new insight into the literature on small firm growth.

现代开发技术的集成及其在新产品开发中的应用

在新车开发或改型开发的过程中,为了提高产品的开发效率和开发质量,目前主流的开发流程一般包括物理模型制作(1∶1或1∶4)→物理模型的数字化(点云获取与处理)→逆向三维建模(在Catia等三维软件中)→样件快速制作加工→三坐标检测、数模比对检测等过程。文章结合开发流程介绍了现代开发手段的集成应用,并给出了各种开发技术的应用实例。     

从高速增长走向和谐发展的中国经济

本文将中国经济快速增长的影响因素归结为7方面:工业化和城市化的快速推进为中国经济长期高速增长提供了充足动力;大众消费时代来临,消费需求成为支撑中国经济持续高速增长最稳定的因素;对外开放的深化,对中国经济具有重要推动作用;高储蓄为中国经济持续高速增长提供了充足的资金保证;丰富的劳动力供给和日益提高的劳动力素质成为中国经济持续高速增长的基本要素;技术进步是中国经济持续高速增长的重要因素;“中国模式”的经济体制改革成就了中国经济的奇迹。同时,本文认为中国经济发展面临结构失衡的压力、来自分配差距扩大的压力、面临资源和环境方面的压力和人口快速老龄化的压力。综观中国经济的全局,支撑经济快速增长的因素还没有改变,只要我们认真贯彻落实科学发展观,坚持以人为本,坚持全面协调和可持续发展,认真对待、妥善处理好发展中的各种矛盾和问题,在未来10—15年时期里,中国经济继续保持7%以上的增长速度是完全可以做到的。但是,从现在所处的发展阶段和面临的问题看,今后中国最为重要、最为迫切的是要在科学发展观的统领下保持和谐发展,更加重视协调发展,更加重视经济增长的质量和效益,更加重视结构优化,更加重视深层次的改革。
