上市公司横向并购资本运营绩效实证研究

为了突破经济发展瓶颈,兼并重组活动如火如荼,其中横向并购活动最为活跃。本文以2011~2015年49 家上市公司为研究对象,采用因子分析法实证分析了上市公司横向并购前后2 年资本运营绩效。结果表明：上市公司横向并购资本运行绩效总体呈现下降趋势,尚未达到预期目的。基于此,提出相关建议：首先,制定正确的并购目标。其次,经营管理者多借助于专业性价值评估机构,避免对被合并方估值过高。再次,不高估企业剩余资产管理能力。最后,调动员工积极性,开拓专属管理资源,做好企业人力资源整合工作。     

Changing network pictures: Evidence from mergers and acquisitions

A merger or acquisition may cause dramatic changes in a business network, which in turn affect managerial cognition as well as managerial activities. We use the concepts of ‘network pictures’ and ‘networking’ to illustrate and analyse changes in managerial sense-making and networking activities following a merger or acquisition. The paper focuses on acquiring, acquired or merging parties and those companies with which they have direct customer relationships. Based on three case studies comprising seven acquisitions and one merger, we show that following a merger or acquisition managers may need to adapt their previous network pictures in a radical way; these adaptations are, however, not always realized as shifts in network pictures and adjustments in networking activities by all the managers involved. Whereas the merging parties' network pictures and networking activities are largely driven by their perception of customers' needs and developments, it is not certain that the merger or acquisition is enacted accordingly. The paper contributes to a clearer view on the conceptual interdependence of the constructs of network pictures and networking in multi-actor situations and thus it develops a network perspective on mergers and acquisitions.     

Should competition authorities care about conglomerate mergers?

Mergers and acquisitions may change competition even when they do not affect market structure, a case known as conglomerate mergers. In this paper, we explore a wave of acquisitions of higher education institutions by educational groups in Brazil, which allows us to disentangle the effects of conglomerate mergers and of horizontal mergers on price, quantity, and quality indicators. Our findings show that multiunit organizations are able to increase some quality indicators. As for the effect on price and quantity, results are different. For conglomerate mergers, we estimated an increase in the number of freshmen and tuition fees, whereas for acquisitions that lead to horizontal concentration there is no increase in quantity, just in prices. Also these effects are larger the smaller the market share of the acquired HEI. On the whole, our findings are consistent with the hypothesis that multiunit operations increase efficiency, but only conglomerate mergers tend to pass those gains on to consumers. Results also indicate that greater caution should be taken in market extension mergers when the acquired firm has a clear dominant position.     

Creating or destroying value through mergers and acquisitions: A marketing perspective

A majority of mergers and acquisitions are horizontal, combining companies within the same industry. They are most frequently motivated by a desire to achieve revenue and profit growth through market expansion or by adding new product lines, with cost efficiencies being a secondary agenda. However, the modest body of literature on post-merger performance using marketing metrics indicates that marketing objectives such as sales revenue and market share growth are rarely achieved. This paper reports on a detailed study of 45 M&A deals undertaken to develop a deeper understanding of how marketing performance is affected by mergers and acquisitions. Our results show that marketing performance improved along two dimensions — sales revenue growth, and a reduction in selling, marketing and administrative costs as a percentage of sales revenue, suggesting the realisation of synergies in these areas — economies of scale and scope. However, these benefits did not follow through into better returns on sales suggesting that the marketing cost economies are not sufficient to outweigh cost diseconomies in other parts of the business.

Cross-border mergers and acquisitions by Chinese listed companies: A principal–principal perspective

Chinese listed firms have gained the world’s attention with several ambitious, high-profile cross-border mergers and acquisitions. In most of these deals, the Chinese government is the largest shareholder of the acquiring firms. As such, it may be the case that the Chinese government pushes through such deals even though they are not in the best interests of minority shareholders, giving rise to principal–principal conflicts. Along these lines, we hypothesize that increased government ownership in the acquiring firm will be associated with investors viewing a cross-border merger deal in less favorable terms. In addition, we hypothesize that environmental complexity will moderate this negative relationship. We test our hypotheses with a sample of cross-border mergers and acquisitions involving Chinese firms from 2000 to 2008. We find support for the main hypothesis, that is, that investors are indeed skeptical of cross-border mergers and acquisitions deals when the government is the majority owner (i.e., principal–principal conflicts). However, we find no support for the moderating effect. We discuss the implications of these findings for researchers and practitioners and suggest future research directions.     

Assessing the effects of mergers and acquisitions on firm performance,plant productivity,and workers: newl evidence from matched employer‐employee data

Empirical studies of mergers and acquisitions typically focus on firm‐level financial performance. In contrast, we use human capital theory to model these events as transactions that simultaneously have cross‐level, real effects on workers, plants, and firms. Our empirical analysis is based on longitudinal, linked employer‐employee data for virtually all Swedish manufacturing firms and employees. We find that mergers and acquisitions enhance plant productivity, although they also result in the downsizing of establishments and firms. Firm performance does not decline in the aftermath of these ownership changes. We conclude that such transactions constitute a mechanism for improving the sorting and matching of plants and workers to more efficient uses. Copyright © 2010 John Wiley & Sons, Ltd.     

Role of industry relatedness in performance of Indian acquirers—Long and short run effects

We explore the effect of industry relatedness on the performance of Indian acquirers using both short run and long run performance measures. We argue that mergers and acquisitions are distinct strategies, because of the unique regulatory structure and equity ownership pattern that exists in India. Their choice depends on control considerations on the one hand and regulatory imperatives on the other. Correspondingly, their sources of value creation or destruction do not always correspond to extant theories of synergy or agency. We present a modified synergy story and illustrate that, while related acquisitions create value and non-related acquisitions destroy value, both related and unrelated mergers create value.

Market Structure after Horizontal Mergers: Evidence from the Banking Industry

Antitrust agencies use measures of market structure to evaluate the likely competitive effects of proposed mergers, but little is known about how measures of market structure change over time, particularly after consummation of mergers and acquisitions. This paper analyzes the changes in market structure 3 and 5 years after mergers in the US banking industry. Our analysis suggests that concentration decreases and the number of banks increases in banking markets where mergers resulted in high concentration levels. In markets where the level of concentration changed by a relatively large amount, our findings are more ambiguous, as the level of concentration decreases, but no effect is found on the number of competitors.     

The long‐term performance of horizontal acquisitions

This paper examines how value is created in horizontal mergers and acquisitions. More specifically, it examines the impact of post‐acquisition asset divestiture and resource redeployment on the long‐term performance of horizontal acquisitions. The data come from a detailed survey of acquiring firm managers and cover 253 horizontal mergers and acquisitions that were initiated by European and U.S. firms in manufacturing industries for the period 1988–1992. This study incorporates insights from the cost efficiency and resource‐based theories to propose a model of the effects of asset divestiture and resource redeployment on long‐term acquisition performance. Overall, our results show that both asset divestiture and resource redeployment can contribute to acquisition performance, with, however, a significant risk of damaging acquisition performance when the divested assets and redeployed resources are those of the target.

Employment Effects of Acquisitions: Evidence from Acquired European Firms

This paper examines the employment effects of acquisitions for acquired European firms, taking non-random selection of acquisition targets explicitly into account. Following the empirical firm growth literature and theories put forward in the mergers and acquisition (M&A) literature, we control for convergence dynamics in firm size and distinguish between different types of acquisitions. Empirically, we estimate an endogenous treatment model using accounting data for a newly created sample of acquired and non-acquired European firms. Our results reveal positive employment effects for different types of acquisitions indicating that M&As likely induce efficiency gains.     

Strategic business fits and corporate acquisition: Empirical evidence

A sample of 218 mergers made by randomly selected bidders during 1962 to 1983 is classified by changes in the product market opportunities of the bidder firms. Multivariate regression analysis shows that acquisitions which permit the bidder access to new but related markets create the most value with the least variance.     

The impact of FDI through mergers and acquisitions on innovation in target firms

This paper analyzes the effects of cross-border mergers and acquisitions on innovation activities in target firms. The empirical analysis is based on survey and ownership data for a large sample of small- and medium-sized German firms. After controlling for endogeneity and selection bias, we find that foreign acquisitions have a large negative impact on the propensity to perform innovation activities and a negative impact on average R&D expenditures in innovative firms. Furthermore, innovation output, measured as product and process innovations, and the share of sales from product innovations, is not significantly affected by a foreign acquisition for a given amount of innovation efforts. Hence, the estimation results do not provide any evidence of significant technology transfer through foreign acquisitions in form of a higher innovation success.     

Is speed of integration really a success factor of mergers and acquisitions? An analysis of the role of internal and external relatedness

Previous research on mergers and acquisitions has neglected the issue of speed of postmerger integration by and large. This paper argues that there are benefits and detriments associated with speed of integration. Thus, in some situations speed may be highly beneficial whereas in others it may be harmful to the success of a merger or acquisition. It is argued that the benefits and detriments of speed of integration depend on the magnitude of internal and external relatedness between the merging firms prior to the merger or acquisition. Results from a survey of 232 horizontal mergers and acquisitions show that speed is most beneficial when external relatedness is low and at the same time internal relatedness is high. In contrast, speed is highly detrimental in the case of low internal and high external relatedness. Copyright © 2006 John Wiley & Sons, Ltd.     

Globalisation, strategic alliances, acquisitions and technology transfer. Lessons from ICL/Fujitsu and Rover/Honda and BMW

As globalisation proceeds major national companies may find themselves involved in domestic mergers and acquisitions, only to have turn later to international co-operation. International strategic alliances, though, often eventually move on to international acquisition, either involving the alliance partner (as in the case of ICL/Fujitsu) or some third party (as in the case of Rover/Honda/BMW). This article draws on research in Britain and Japan to investigate the strategic and technological implications of such co-operative trajectories. Two acid tests appear to determine whether such inter-company co-operations (whether mergers, acquisitions or strategic alliances) are likely ultimately to prove transitory, or whether they will progress towards some more stable inter-action: ?Is the arrangement ‘adding value’ technologically? Is it contributing to some process of international integration? ?Technological synergies and learning possibilities are often played down initially in domestic acquisitions, and even in international strategic alliances offering particular scope for technology transfer; but they are important in determining long term outcomes.
