随着我国电网逐渐向智能电网迈进,信息技术在电能传输、转换、分配、调度等方面的应用,使电力企业可以进行结构调整,提高电力系统管理水平。据统计,2011年,我国电力信息化投资达220亿元,2012-2015年,电力工程建设稳步推进。为了促进电力企业全面开展项目成本核算和有效控制,提高电力工程项目的效益,确定了典型方案设计模块,通过定额规则库与典型方案设计相匹配的方法,解决了安装过程中定额第一版遗留的一些问题,并通过设计选型等措施加强了成本控制。 相似文献

研究目的:针对城市化进程中的土地低效利用以及过度集约问题,探讨不同城市化发展阶段的土地集约利用状况及适度集约利用状态。研究方法:采用匹配度模型、曲线估计模型和多目标规划模型,对山西省的土地集约利用进行分区优化。研究结果:(1)1999—2012年山西省土地集约利用与城市化水平之间的匹配趋势逐渐由失调、磨合向协调转变,但不同地区之间的匹配水平差距却在逐渐扩大;(2)2018年山西省城市化水平处于低于30%、30%~70%和高于70%时,以单位城镇建设用地固定资产投资额为表征的土地适度集约利用值分别为249.93万元/km~2、367.57万元/km~2和692.72万元/km~2,两项指标叠加全省可划分为平稳发展区、重点挖潜区和优化拓展区,并提出了不同地区差别化的建设用地管控政策。研究结论:不同城市化发展阶段的土地适度集约利用研究能为制定区域差别化政策提供参考,以促进该地区的土地集约利用水平达到适度状态。 相似文献

We developed and tested a research model in which employee well-being human resource (HR) attribution differentially influences the intention to change jobs across organizations (i.e., external job change intention) versus that within the same organization (i.e., internal job change intention). Furthermore, we posited that task idiosyncratic deals (I-deals) moderated the relationships between employee well-being HR attribution and external and internal job change intentions. Results indicated that employee well-being HR attribution was negatively related to external job change intention, but positively related to internal job change intention. Further, task I-deals significantly moderated the relationships between employee well-being HR attribution and external and internal job change intention. Specifically, employee well-being HR attribution played a less important role in reducing external job change intention when task I-deals were high rather than low. On the other hand, high task I-deals significantly strengthened the positive relationship between employee well-being HR attribution and internal job change intention. Our study extends the careers literature by differentiating the impact of employee well-being HR attribution on job change intentions within an organization compared with that across organizations and the important role of supervisors in enhancing or mitigating these effects. 相似文献

Using discretionary accruals to proxy for earnings quality, this study investigates whether and how the first voluntary internal control reporting in 2007 is associated with earnings quality in China. We find that earnings quality is higher in 2007, yet not in 2006, for public companies issuing a first-time voluntary unqualified internal control report, compared with listed firms not issuing an internal control report. Our findings are consistent with a signalling of performance explanation and inconsistent with a signalling of effectiveness explanation. We also find that earnings quality is lower for public companies issuing an internal control report mentioning a weakness, compared with public companies not issuing an internal control report. Overall, our study suggests that public companies conduct diligent self-assessments when issuing a first-time voluntary unqualified internal control report. Consequently, there is an improvement in earnings quality. 相似文献

Genuine reviews are essential for financial performance and for customer trust. In the case of a negative experience, withholding negative reviews may lead to biased online information. This paper aims to investigate two factors that may prompt customers to withhold their complaints (i.e., identity disclosure and locus of control). The study adopts a sequential exploratory mixed-method approach. An exploratory interview phase compares public vs anonymous online environments, and explores the reasons why dissatisfied customers might decide not to complain. An experiment then shows that vulnerability is a key mechanism preventing negative reviews. This effect is exaggerated when customers perceive that they do not have control over the events happening in their lives (i.e., external locus of control). Our work uncovers an important determinant of online complaint behavior, vulnerability. It also offers practical suggestions, such as improving confidentiality, to increase a customer's willingness to complain following a negative experience. 相似文献

Insourcing to countermand previous outsourcing decisions is becoming a widespread practice among firms. While the underlying performance drivers for firms (e.g., lead times, responsiveness, or security of supply) are well understood, the behavioural aspects underlying managerial decision-making processes regarding insourcing remain overlooked in empirical research. We study the effects of managers' attitudes toward insourcing, their perceived behavioural control (PBC) over the respective insourcing decision, and the effect of mimetic pressure on insourcing decision intentions and behaviour, while grounding our model in the Theory of Planned Behaviour (TPB). We test hypotheses with data gathered in a vignette-based experiment among 145 managers and apply stepwise regression analysis to find support for the positive effects of attitude and mimetic pressure on intentions to insource. Our results found no support for the effect of managers’ PBC. We find moderation effects among the internal drivers (attitude and PBC) and between internal and external drivers (attitude and mimetic pressure) on insourcing behaviour. With these findings, we provide evidence of a unique boundary condition to the TPB in the insourcing context by explaining supply chain design choices with neo-classical and behavioural theory. We emphasize important behavioural aspects in insourcing decision-making and caution supply managers in this regard. 相似文献

This study examines how vertical separation of transmission control affects the wholesale market efficiency in the electric power industry. We analyze a unique regional electricity wholesale market in the U.S. where initially restructuring only occurred in the transmission sector. Following a commonly-used best dispatch model (Wolfram, 1999; Borenstein et al., 2002), we simulate competitive benchmark prices and compare with the best estimates available for actual prices to measure price-cost markups of the wholesale market. Empirical results demonstrate that the vertical separation of transmission control led to a significant increase in market markups in peak-load hours, documenting evidence of enhanced market power. Although we also find a reduction in the price-cost margin in low-demand hours, we reserve caution for this finding. 相似文献

The centrality of cross‐functional integration (CFI) to supply chain theory and practice has long been recognized. Yet researchers continue to struggle with consistently defining or measuring the CFI construct, thus limiting the utility of CFI research. This research develops (1) a comprehensive definition of CFI that synthesizes previous supply chain research and (2) a valid set of scale items that measure the conceptual domain outlined by this definition. The goal is to build a common foundation for extending knowledge on CFI's antecedents and consequences, and ultimately to improve scholars’ ability to guide a broader practitioner community still struggling to achieve integration in their organizations. 相似文献
