上海漕泾电厂1000MW机组供热改造热经济性分析

本文以上海漕泾电厂1000MW机组为研究对象,分析对比了机组不同供热工况下的热力经济性变化情况。结果表明,不论何种负荷,冷段供热工况的汽机热耗、发电煤耗及供电煤耗等均低于纯凝工况,一抽供热工况居于两者之间,机组对外供热经济性提高。当负荷低于700MW时,冷段抽汽无法满足供热负荷对温度压力的需求,建议使用一抽供热;当负荷较高时,使用经济性较好的冷段供热,一抽供热作为辅助汽源,保证供热的稳定性和可靠性。对大型燃煤机组进行供热改造,具有良好的经济效益和社会效益。

公司治理视角下地勘单位内部控制体系探讨

地勘单位是计划经济形成的产物,当前的地勘单位仍处于转轨变型、事企分离的关键时刻,而作为企业管理重要核心内容的内部控制就显得尤为重要.完善的公司治理结构能够提供一个优良的环境,是内部控制体系畅通运行的首先条件.应从公司治理的角度出发,在分析当前地勘单位内部控制现状的基础上,构建适合我国地勘单位现状的以内部控制管理程序、内部控制要素、内部控制活动内容与方法"三维一体、相互融合"的内部控制体系.以促进我国地勘单位内部控制体系实现目标以及方法措施的飞跃与融合.

Industrial relationships and the effects of different types of connections

Emphasizing the primary and secondary functions in business networks, this paper is based on the presumption that the primary function of the focal dyadic relationship is connected to business, political, ancillary and competitive relationships, i.e. what has been denoted as the secondary function. The question is how these secondary functions affect the primary function. The conceptual view developed for the focal dyadic relationship is founded on the two key relationship concepts of trust and commitment. The empirical study is based on a survey of 353 firms and their most important customer relationships. The analysis examines nine hypotheses through a structural model in LISREL. Conclusions from the statistical test show the heterogeneity in the impacts of these different types of connections on trust and commitment. Knowledge of the impact of these connections can aid the further understanding of relationship connections and also assist business firms in developing strategies towards these units.

Optimal productive size of hospital's intensive care units

Authors of past studies focusing on returns to scale in hospitals proffered mixed results. These seemingly contradictory findings have probably arisen due to different methodological approaches (parametric or non parametric), different aggregation levels of analysis (hospital/department/units), nature of data (quantity data or economic values) and also due to technological improvements operating in hospitals and case mix adjustment to account for the severity of patients' conditions.In this paper, we apply a new approach to determining returns to scale for single and multi-output homogenous technologies, which is different from traditional DEA models. Our approach is characterized by (1) a non parametric approach based on quantity data that allows us to avoid assumptions on cost minimization or profit maximization behavior of hospitals, on relevancy of economic values for hospitals (costs, revenues and prices) and on a priori specification of the health care production function, and (2) an analysis of optimal productivity size at both the disaggregated level of intensive care units and at the aggregated hospital level. The methodological advantage is that we can unambiguously define increasing returns to scale, which is lacking in more traditional non-parametric approaches because of the convexity assumption imposed earlier. We apply the methodology to intensive care units (cardiac care (CICU), medical/surgical care (MSICU), pediatric care (PCIU) and neonatal care (NICU), which are operating in 235 general short term hospitals of Florida state in 2005. We also consider the hospital level by analyzing the general activity of the hospitals in our population.To summarize our findings, we find that 60% of intensive care units are operating at increasing returns to scale, 10% are operating at optimal productive size and 30% are characterized by decreasing returns to scale. In average intensive care units operate 40% under the optimal size. The policy implication of this result should be an increase of the size of all types of intensive care units to meet productivity gains. The picture is completely reversed at the aggregate hospital level. Here decreasing returns to scale prevail for 65% of hospitals while only one fourth are operating at increasing returns to scale. In average hospitals' number of beds should decrease by 40% to reach the optimal productivity size. One policy solution may include reallocating resources from general beds to the more specialized beds.     

Innovation and control in the multinational firm: A comparison of political and contingency approaches

This study focuses on control mechanisms used by multinational corporations (MNCs) to manage their extra‐national R&D units. Drawing on both the literature on organizational power and contingency theory, this study develops and empirically tests a set of hypotheses aimed at explaining how headquarters control their overseas R&D units. Data collected from 134 R&D units of German MNCs serve to test the hypotheses. Results highlight the importance of the units' R&D mandate and its interdependence in explaining control mechanisms. Moreover, they indicate a relatively weak predictive power of political approaches compared to contingency approaches. Copyright © 2007 John Wiley & Sons, Ltd.
