社会资本控制链架构及其稳定性研究——基于博元投资与国美电器的案例分析

在公司治理中,实际控制人同时运用股权控制和社会资本控制已是不争的事实,随着对社会资本控制链研究的深入,"社会资本契合度"替代效应"等相关概念逐渐被提出.本文在承续前人研究的基础上,将博元投资与国美电器的社会资本控制链架构进行对比分析,指出在垂直式社会资本控制链架构中,社会资本即使在股权控制水平低于相对控股时,依然具有替代效应.同时水平式的社会资本控制链易产生多个社会资本节点,致使其稳定性下降,而垂直型的社会资本控制链,因其单极和多层的架构使得整条社会资本控制链的稳定性得以提升.     

Negotiators' Communication, Perception of Their Counterparts, and Performance in Dyadic E-negotiations

The aim of this study was to improve our understanding of negotiation strategies, behaviors, and outcomes, and the relationships between these factors based on data collected from questionnaires, actual behavior during the negotiation process implemented using e-negotiation system, and the negotiation outcomes. This study clustered the negotiators based on either the negotiators' own strategies or their thoughts about those of their partners. This resulted in a division into cooperative and noncooperative clusters. We found that the negotiators whose own strategies are less cooperative tend to submit more offers but fewer messages. However, these people consIDer that they have less control over the negotiation process compared with those who adopt a more cooperative strategy, who make fewer offers but send more messages. Those in the cooperative cluster consistently feel friendlier about the negotiation and more satisfied with the outcome and their performance. Further, there is a correlation not only between self-strategies and the thoughts about partners' strategies, but also between strategies and final agreements. Finally, the proportion of negotiations reaching agreement is larger for the cooperative cluster than for the noncooperative cluster.     

Transformation of China's energy sector: trends and challenges

The conclusions presented here sum up the contributions in the Special Issue regarding the managing of China's energy sector, particularly regarding the demand and profile of energy as well as the marketization of the sector. Strategic, organizational and policy issues relevant to the main theme are set out. Both demand and supply scenarios for the nation's energy are seen as in flux, as the economy slackens and dependence on imports rises. Unprecedented levels of urban environmental pollution and steady growth of energy consumption in the wake of a rising living standard have brought the issue to headline-prominence as never before. China's rapidly increasing renewable energy will not change its heavy reliance on coal and a lesser extent oil in the coming decade. After decades of transformation, China's energy sector now operates in a domestic market characterized by strong governmental influence and monopolistic state firms. Abroad, China's firms are exposed to heavier market pressure and competition. While the state's policies have succeeded in ensuring energy supplies and propelling China's renewable energy manufacturers into global prominence and opening up domestic market, much room for improvement exists in the competitiveness of the domestic market and domestic energy firms, transparency of pricing and the effectiveness of regulation.     

Hospital efficiency under global budgeting: evidence from Taiwan

Global budgeting sets a predetermined cap to restrain health expenditure, but the fixed budget for medical providers could result in less efficient services. This paper measures hospital efficiency under global budgeting using simultaneous stochastic frontier analysis, stressing that physicians and dentists within a hospital were under separate budgets in Taiwan. Empirical results show that hospital efficiency was not improved after global budgeting, and physicians were found to be less efficient than dentists. The physicians and dentists within the same hospital were also found to be less integrated after global budgeting. Empirical results show that a joint analysis improves the estimation efficiency from separate analysis and suggest that the aggregate inefficiency came mostly from physicians in hospitals that were small, public, non-teaching, located in small markets and had a low market share. Except for public hospitals, physicians and dentists in the above hospitals were also found to be less integrated.     

Board Gender Diversity,Auditor Fees,and Auditor Choice

We examine whether the presence of female directors and female audit committee members affect audit quality in terms of audit effort and auditor choice by using observations from a sample of U.S. firms, spanning the years 2001–2011. We find, after controlling for endogeneity and other board, firm, and industry characteristics, that firms with gender‐diverse boards (audit committees) pay 6 percent (8 percent) higher audit fees and are 6 percent (7 percent) more likely to choose specialist auditors compared to all‐male boards (audit committees). Our findings suggest that boards (audit committees) with female directors (members) are likely to demand higher audit quality, ceteris paribus.     

Addictive behavior and endogenous growth

This paper sets up an endogenous-growth model in which the consumer's preference is subject to habitual consumption, and examines how consumption habits will govern the rate of sustained growth. It is found that the habitual behavior may be either growth-enhancingor growth-reducing, depending upon whether the substitution between intertemporal consumption is inelastic and whether the consumption experience is harmful or beneficial to the agents. It is also found, given that the elasticity of intertemporal substitution is less than unity, that the learning speed of consumption habits has a positive (negative) impact on the balanced-growth rate if the consumption experience is harmful (beneficial) to the agents.

Bundling digitized logistics activities and its performance implications

Bundling information technology (IT) applications to support logistics activities provides a means for firms to improve their logistics performance. Grounded in the logistics management and management information systems literature, as well as the resource-based view (RBV) of the firm, this study empirically: (i) investigates if there exist digitized logistics activities bundles in firms; and if so, (ii) explores the association between digitized logistics activities bundles and logistics performance of firms in terms of logistics cost and logistics service improvements. We surveyed 227 trading firms in Hong Kong and performed a factor analysis of the survey data, from which we identified three digitized logistics activities bundles and found the sample firms were clustered into four types based on the patterns of their digitized logistics activities. We then carried out a MANOVA on the data, the results of which show that different patterns of digitizing logistics activities are associated with different logistics performance outcomes. Specifically, firms with more extensive digitized logistics activities bundles and utilizing them more intensively achieve better logistics performance. Academic and managerial implications for digitizing logistics activities to improve logistics performance are discussed.     

技术产出弹性、两阶段创新效率与高技术产业竞争力研究

以技术存量水平为门槛变量,对高技术产业生产方程进行分解,发现区域间技术产出弹性存在显著差异,据此对29个地区分组建立前沿面,测度知识生产和成果转化两阶段创新效率,并研究创新效率对区域高技术产业竞争力的实际影响。结果表明：①先发地区凭借较高的技术产出弹性,获得远超其它地区的高速增长;②产品生产中的创新效率,即成果转化率提升能够显著促进产业竞争力提升;③知识生产中全要素生产率提升能够显著扩大产业竞争力上升幅度,但知识生产中技术效率提升对产业竞争力的影响并不显著。     

中国劳资关系的城乡户籍差异

本文利用最近的企业和农民工调查数据探讨了劳资关系城乡户籍差异问题。城乡工人在劳资关系各方面的巨大差异源于两个方面 :一是人力资本水平差异和就业企业的差异 ;二是农民工受到的户籍歧视。研究结果发现 ,前者解释了两类工人劳资关系差异的 70 %— 80 % ,说明人力资本和企业状况是决定工人待遇的主要因素 ;后者解释了两类工人劳资关系差异的 2 0 %— 3 0 % ,户籍歧视所造成的差距同样是不容忽视的。除劳动合同方面外 ,农民工在工资、养老保险、医疗保险、失业保险以及工会参与等方面均遭到户籍歧视。研究结果暗示仅仅关注工资收入的城乡歧视是不够的 ,同时也为更全面的劳动力市场校正政策提供了经验支持
