产业销售起飞研究——以绿色农业产业为例

近年产业销售起飞机理成为产业组织和市场营销的研究热点。目前研究分支有:以产品销售扩散研究发展成的经典的Bass模型,但产品销售起飞本质上是个二分事件,所以扩散流派并没很好倡导和揭示起飞机理;Golder等人不仅提出起飞概念,而且在研究方法上借用生存分析等技术,并取得重大进展。采用"起飞阈值"法对绿色农业产业销售时机进行实证分析,结果表明绿色农业产业在2002年实现产业起飞。

Developing design principles for the digitalisation of purchasing and supply management

This paper develops an approach to evaluating designs for digitalisation interventions in purchasing and supply management (PSM), and identifies some fundamental design principles for such interventions. A set of advanced technologies for digitalisation and a theory-based set of seven value drivers for PSM are identified for the proposed grid to facilitate the design of applications and interventions for digitalising PSM. The grid relates the digital technologies to the PSM value drivers in a matrix-like manner, allowing the structured consideration of the space defined by these two dimensions. The proposed approach to the strategic evolution of digitalisation in PSM is tested and its utility is demonstrated in analyses of practitioner literature and multiple case-study-based perspectives on PSM digitalisation. Two fundamental design principles relating to the use of the grid, or to the filling of its space, are set out, thus the research provides new theoretical perspectives on the design of advanced forms of PSM digitalisation. The proposed grid may be used in application design, communicating current and future states of PSM digitalisation to stakeholders, and specifically in developing a future-oriented strategy with a digitalization element for the PSM function.     

运输成本、劳动力流动与制造业区域分布

近年来,中国制造业的区域发展不平衡,其中的重要影响因素是什么?本文通过构建经济地理的分析框架,分析了运输成本和劳动力流动在中国特有条件下的作用机制。运输成本差异形成了制造业在沿海地区的选址优势,而这一优势和目前的高劳动力流动成本一起,形成了沿海高成本压力而内地收入低下的新空间“二元”结构。同时,我们计算了区域经济的实际数据对这一机制进行印证,假如这一局面继续维持,它将妨碍沿海和内地产业分工与均衡发展。文章还认为,因为经济集中的趋势是内生的,所以平衡区域经济发展的政策取向应该是促进性而不是限制性的。     

我国建筑业市场进入壁垒为何失效

我国建筑业具有典型的分散型产业组织特征,市场集中度偏低的主要原因在于进入门槛较低。规模经济、产品差异化、必要资本量、绝对费用等结构性进入壁垒没有起到限制企业进入的作用,而企业资质管理作为一种市场准入制度,虽然构成了建筑市场最主要的进入壁垒,但在等级设定、专业划分等方面缺乏长期性和稳定性,长期来看对于抑制过度进入和优化产业结构的作用比较有限。     

区域战略性新兴产业核心竞争力的识别与培育——以天津市新能源产业为例

区域高技术产业发展的动态效率分析

运用非参数DEA-Malmquist指数法,根据2003—2007年的面板数据对我国珠三角、长三角、环渤海三大区域的高技术产业全要素生产率进行测算和分析,估算出三大区域9省市全要素生产率变化指数、效率变化指数和技术进步指数。结果表明,先发省市的高新技术产业基本处于生命周期的成熟阶段,年度技术进步指数在下滑,效率变化指数呈现不变或上升趋势,产业集群优势开始呈现,并提出进一步发展区域高技术产业的对策。     

Industry evolution and R&D externalities

R&D externalities can imply ranges of aggregate increasing returns to scale in R&D. As a consequence several equilibria can exist involving different numbers of firms and different R&D investment levels. In a theoretical model the equilibrium dynamics are analyzed, showing that cyclical fluctuations of the number of firms and R&D investment may be expected, and that the long-run equilibrium is highly sensitive to investors' initial beliefs. The model is tested empirically using a unique database comprising competing firms in various R&D races.
