双重嵌入下网络惯例刚性对探索性创新的影响

网络组织常出现的惯例刚性现象会影响其探索性创新，但惯例刚性作用效应会受到网络嵌入的影响。为了揭示双重网络嵌入下网络惯例刚性对探索性创新的作用机制，对软件业、高端制造业、信息传输业、制药等行业258份调查数据进行实证分析，结果发现：网络认知刚性、网络行为刚性都不利于企业探索性创新；网络惯例刚性与探索性创新之间的关系受其所嵌入的双重网络影响。在较高社会网络嵌入差异情况下，网络认知刚性、网络行为刚性与探索性创新的负向关系加强。相以地，在较高知识网络嵌入下，网络认知刚性、网络行为刚性与探索性创新的负向关系也会加强。     

企业文化刚性与适应性之间的矛盾及其化解

企业文化被看作竞争优势的一个重要来源。然而，企业文化具有的刚性特征又导致它对竞争优势的保持与创新产生了抑制作用。应以企业文化的权变观为基础，分析企业文化刚性的成因和表现，探索文化的刚性与适应性之间的矛盾，选择化解文化刚性的有效途径。     

HETEROGENEITY IN REAL WAGE CYCLICALITY

This paper presents evidence that real wage cyclicality can be a particularly heterogeneous parameter, depending on different worker characteristics and also on the specific stage of the business cycle. Using matched employer–employee panel data for Portugal covering the period 1986–2004, real wages are shown to be considerably more procyclical during recessions than during expansions, resulting in relatively moderate overall levels of cyclicality (about −0.6). However, most of the procyclicality during downturns is shown to be driven by the younger employees, as older workers appear to be insulated from the business cycle. Moreover, movers between firms typically display higher cyclicality than workers that stay in the same firm, regardless of whether the latter move or not between job levels. Most results also hold when considering basic wages instead of total wages, except that the procyclicality of movers during downturns is substantially higher.

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.     

资产专用视角下的技术刚性形成机理及其克服

本文通过对企业核心能力刚性的研究综述，延伸并引出了技术刚性的概念，并且分别从大型和中小型企业两个角度分析了刚性的形成机理，阐述了刚性本质，认为资产专用性是企业技术刚性形成的根本原因，最后提出技术刚性克服的对策与建议。     

战略调整中的企业核心刚性及其治理

企业核心能力是企业竞争优势的源泉。但是,在管理理论研究和实践中人们又会发现,企业核心能力形成的过程往往也伴随着核心刚性的生成。在内外环境发生变化时,它会阻碍企业创新,使企业失去持续的竞争优势,并最终导致企业绩效的不断恶化。针对这一问题,首先探讨了核心刚性的界定及表现,然后分析了核心刚性的形成机理,最后从核心刚性的本质出发提出了核心刚性的治理对策。     

关于我国控制性详细规划问题与改革的再思考——基于一个规划选址案例的分析

控制性详细规划是我国城市土地开发控制的直接法定依据.然而,由于社会经济发展过程中各种不确定性因素的影响,控规在我国城市建设中并没有起到预期的作用.基于一个规划选址案例的分析,进一步探讨了控制性详细规划所面临的“刚性”与“弹性”的根本矛盾,并从控规编制内容和方法、控规编制和实施体制等方面提出了相应的对策建议,其中,特殊发...     

欧洲债务危机与社会养老保障的国家特征及中国借鉴

欧洲政府债务比重长期偏高的国家表现出高社会保障和福利支出比重、高社会养老保障支出比重、高公共养老金替代率和再分配功能偏低的"三高一低"特征,而这在很大程度上源于社会养老保障及其改革的刚性。因此,中国应该从长经济周期的视角来协调保障与经济发展的关系,当前社会保障建设则要适当滞后于经济发展,同时,建立多层次的退休金支付结构,强化基础养老金"保基本"的横向再分配功能,并构建养老金关键参数的弹性调整机制。
