国内外电力建设工程竣工移交条件差异及合同纠纷分析

国内外电力建设工程竣工移交时,在性能试验责任主体、时间、试验项目等多方面存在较多差异,进而导致了工程投入商业运行、颁发移交生产交接书、缺陷责任期起始和结束等诸多时间的不一致,这些差异和不一致可能引起业主与EPC承包商之间的合同纠纷。本文对上述差异和可能引起的纠纷进行了分析,并提出对策和建议。     

环境规制、市场势力与企业创新

具有市场势力的企业面临环境规制时可以通过研发创新实现波特效应，也可以通过转嫁合规成本实现利润最大化。本文利用新《环境保护法》实施这一准自然实验，基于双重差分和三重差分模型系统地评估了环境强监管对具有不同市场势力的上市公司研发创新的影响。研究发现，新《环境保护法》的实施显著促进了企业的研发创新，市场势力本身与企业创新呈现倒“U”型关系，同时市场势力显著抑制了新《环境保护法》的波特效应。

项目招投标过程中的问题与对策研究

企业项目招投标管理是一种公平、公开、公正的交易方式,在我国社会主义市场经济不断完善的条件下,推行企业项目招标投标管理模式对健全市场竞争机制,提高社会资源的优化配置,提高政府执政能力,遏制不正当的竞争,有着十分重要的意义。但近些年来,我国现行的企业项目招投标管理中还存在一些不可忽视的问题和薄弱环节,本文对其中存在的问题进行了简要的介绍,并提出了相应的解决措施。     

Nonprofit organizations,institutional economics,and systems thinking

The present paper applies the logic of John Kenneth Gailbraith's institutional economics analysis of corporate power to inquiring into the societal role of the nonprofit sector. Building on Galbraith's insight that corporations cause subtle but pervasive societal imbalances, the paper locates the role of nonprofit organizations in compensating for these imbalances, thus showing corporations and nonprofit organizations to be mutually complementary rather than antagonistic actors. This argument is supported by Niklas Luhmann's vision of the precarious relationship between the complexity and sustainability of social systems as well as by Kenneth Boulding's analysis of the farmer and labor movement. Luhmann's and Boulding's perspectives show profit-seeking corporations to be social systems developing high technological complexity at the cost of sacrificing their societal sustainability, while the improvement of the latter constitutes the rationale of many nonprofit organizations. The same systems-theoretic logic suggests, however, that nonprofit organizations may tend to underestimate the technological complexity of implementing their mission-related activities, thereby undermining their own effectiveness.

Carbon and energy prices under uncertainty: A theoretical analysis of fuel switching with heterogenous power plants

European power producers have a major influence on the EU ETS, given that both their CO₂ emissions and their EUA (European Union Allowance) allocations account for more than half of the total volumes of the scheme. Fuel switching is often considered as the main short-term abatement measure under the EU ETS. It consists in substituting combined cycle gas turbines (CCGTs) for hard-coal plants in power generation. Thereby coal plants run for shorter periods, and CO₂ emissions are reduced. This paper provides the first theoretical analysis of fuel switching, in a context where power plants involved are not equally efficient. We begin with a preliminary work using illustrative examples and sensitivity analyses, which enables us to observe how differences in the efficiency of power plants impact the cost of fuel switching, and how this is related to the level of switching effort. Based on this, we build a theoretical model taking into account the effect of differences in the efficiency of power plants involved in fuel switching. We also investigate the effect of the timing of fuel switching abatements, within the temporally defined environment of our dynamic model. Results demonstrate that the gas price and uncontrolled CO₂ emissions act together on the carbon price. We show that the influence of the gas price on the carbon price depends on the level of uncontrolled CO₂ emissions, due to heterogeneity of power plants that are used in the fuel switching process. Furthermore, we show that the time of occurrence of uncontrolled emissions matters so that shocks have a stronger impact when they occur in a period that is closed to the end of the phase.     

Organisational consequences of asymmetries in task dependence: the moderating role of HR practices

This study integrates recent advances in interdependence theory with the literature on commitment‐based HR practices. New research on interdependence theory suggests that differences, or asymmetries, in task dependence among organisational members can cause interests to diverge. Prior research has shown that this can negatively affect interpersonal relations, individual outcomes and team processes. However, these insights gained on the dyadic, individual and team levels of analysis have not yet been explored at the organisational level and, until now, no research had yet connected these advances in interdependence theory to the field of HRM research. Hence, the current study investigates (a) whether asymmetries in task dependence do (or do not) matter at the organisational level and affect organisational effectiveness, (b) why this relationship may work by assessing a key mediator, namely, trust climate and (c) if and how these relationships can be altered by commitment‐based HR practices. Our moderated‐mediation model was tested and fully supported by a multi‐source data set of 8,390 employees from 67 organisations.
