Does state ownership really matter? The dynamic alignment of China's resource environment and firm internationalization strategies

Recent research suggests that unequal access to home country institutional resources affects firm internationalization strategies. We add to this debate, based on an analysis of state-owned (SOEs) and non-state-owned (NSOEs) Chinese mining firms, by developing a more dynamic and multi-layered understanding of this interplay. We find that home institutional support can be ownership-based or performance-based, whereby the former benefits SOEs and the latter favors high-performing NSOEs. Combined, these support structures serve as institutional control mechanisms in promoting competition, performance and loyalty to national policies. In addition, they establish a permanent link between firm- and home country-specific assets and incentivize firms to develop dynamic resource access capabilities at home and abroad. Our findings inform our understanding of the firms-institutions nexus and Chinese foreign direct investment dynamics, especially in industries of strategic importance to the state.

苏南土地改革中的富农问题

苏南土改对富农问题的政策根据是中共中央有关保存富农经济的方针,同时又针对了苏南的具体情况。苏南富农在土地改革前每人平均占有和使用的土地为当地平均数的两倍以上,他们以自己耕种、雇工耕种、出租等方式经营土地。苏南富农对待土地改革的心态是极为复杂的,拥护者有之,怀疑者有之,反对者也有之。苏南各地征收了半地主式富农的出租土地,保留了一般富农的出租土地,对富农的佃入土地抽动较大,对富农的其他财产全部保留。苏南在处理富农问题的过程中曾发生过对富农乱斗乱打和提升富农阶级成分等过左行为,但很快得到纠正。苏南富农在土地改革后每人平均占有的土地仍为当地平均数的两倍以上,苏南是中国大陆保存富农经济最成功的地区。富农经济的完整保存为此后苏南经济的恢复和发展奠定了坚固的基石。     

一种双层小区结构中的切换控制策略

在宽带码分多址双层小区结构系统中提出了一种基于小区覆盖范围和信号能干比判决的切换策略,切换策略使用了基于概率的动态资源预留方案,即在切换时,如果系统中没有空闲资源,则对切换呼叫进行排队。通过仿真表明,该切换策略相对于采用固定资源预留的切换策略,在轻负荷的条件下对话音呼叫的阻塞概率有一定的改善。     

网络环境下图书馆员的角色定位与素质培育

知识经济改变了图书馆的地位和命运,信息化拓展了图书馆的视域和功能,网络化给图书馆注入了新的活力。网络环境下的图书馆员应当是信息馆员、知识馆员、网络馆员。培育馆员的信息素质一要建立继续教育机制;二要加强自身修养;三要走学者化道路。

Changes in Product Attributes and Costs as Drivers of New Product Diffusion and Substitution

Diffusion theory has typically focused on how communication, internal or external to a social system, leads to adoptions and diffusion of an innovation. We develop a diffusion and substitution model based on a somewhat different perspective. In some cases, progressive improvements in product attributes and/or continual cost reduction seem to be a key driver of the diffusion process. For example, after introduction of the 5.25‐inch disk drive, its capacity continually increased, and accordingly, so did customer willingness‐to‐pay. Our model is based on a linear reservation price framework, in which a product is described by its depth (defined as the difference between a product̂s maximum reservation price and its production cost), and its breadth (related to the slope of its reservation price curve), indicating how broadly it appeals across various customer segments. Because of changes in product depths and breadths over time, customers who previously preferred the old product may later prefer the new product, thus creating the diffusion process. While the Bass model describes diffusion as a function of the coefficients of innovation and imitation, in our model, it is described by the coefficients of depth and breadth (the rates of change in relative depth and breadth), along with an S‐coefficient that we associate with the technology S‐curve. We fit our model to data from the disk‐drive and the microprocessor industries.

Blocking Probabilities in Erlang Loss Queues with Advance Reservation

We study the blocking probability in a continuous time loss queue, in which resources can be claimed a random time in advance. We identify classes of loss queues where the advance reservation results in increased or decreased blocking probabilities. The lower blocking probabilities are achieved because the system tends to favor short jobs. We provide analytical and numerical results to establish the connection between the system’s parameters and either an increase or decrease of blocking probabilities, compared to the system without reservation.     

Standardisierungspotentiale lebenszyklusbasierter Modelle des strategischen Kostenmanagements

Tremendous increases in indirect costs can be found in many industries. Consequently, life cycle cost analysis models are getting more important in strategic cost management. However, existing models differ significantly from each other as they have been developed mainly for specific applications. In order to enable a common use of those models, a standardization of these models is required. We examine the potentials of standardizing models for life cycle cost analysis. In a first step, requirements regarding a standard model are derived from literature. As a second step, existing approaches found in literature are compared to the afore derived demands and it is analyzed to what extent they match the standardization requirements. Based on this comparison, we identify and discuss avenues for further research.
