我国企业并购模式的演变与思考

并购初期,阻碍并购成功的因素主要来自于制度环境,其中并购模式是企业对环境适应性的体现,从中折射出并购机制、法律环境、主体间的市场地位、并购效率。证券市场全流通时代的到来必然引发企业新一轮并购热潮,我国企业并购主流模式将产生根本变化。作者详细分析了我国企业并购模式的演变,也提出了相应的对策建议。     

现金并购定价分析

现金并购意味着收购股权的支付方式有别于传统的现金支付方式,而现金并购中的关键环节是真实的反映被并购企业的价值。本文对并购企业价值的决定与相关因素及其使用方法进行了分析,认为完善现金收购中的定价体系,有助于资本市场的进一步发展,对并购定价体系给予科学的分析具有实际意义。     

CONJECTURAL VARIATIONS AND LOCATION THEORY

ABSTRACT. Imperfectly competitive markets, such as those involving spatial separation of producers and consumers are characterized by interactions between competing firms. Actions call forth reactions and the possible reactions form an important part of the information set that should be used to determine the initial actions. One method for dealing with this is the 'conjectoral variation' approach. Despite some shortcomings this methodology sheds considerable light on decision-making in the space economy. Equally importantly, it sheds light on more general microeconomies modelled as spatial analogs. This paper shows that conjectural variations and the nature of competition between rival firms do indeed 'matter' in location choice and more generally in product design. In particular, we shall be concerned with showing how the conjectured responses of rival firms affect their desire to agglomerate.     

产业融合效应与促进我国产业融合的措施

产业融合是信息化进程中呈现的一种产业新范式。产业间的关联性和对效益最大化的追求是产业融合发展的内在动力,在不同的产业领域内,产业融合以不同的方式演进。产业融合带来创新性优化效应、竞争性结构效应、组织性结构效应、竞争性能力效应、消费性能力效应及区域效应等。产业之间的渗透融合是21世纪产业发展的大趋势,我国政府应制定相应的措施来促进我国产业融合及产业的健康发展。     

Gradual location set covering with service quality

Location set covering models were first described in the early 1970s. In their simplest form, they minimize the number of facilities necessary to completely cover a set of customers in some given space, where covering means providing service within a predetermined distance. This paper considers extensions of the basic model that soften the covered/not covered dichotomy and replace it with gradual covering. The models discussed in this work include the quality of service as a criterion. The models are formulated and compared with each other with respect to their size and features. A small series of computational tests concludes the paper.     

基于Hadoop分布式文件系统的单点问题的研究

从Hadoop分布式文件系统的架构出发,对NameNode节点存在的单点问题进行了分析与研究。在这个前提下,针对单点内存瓶颈问题,提出了一个小文件归并算法。此算法以Hadoop为基础,利用Hadoop分布式文件系统的特点,将归并后生成的大文件序列化到Hadoop分布式文件系统,很好地解决了小文件过多时NameNode单点内存瓶颈问题,并提高了系统的性能和可靠性。

Application and extension of the Moore and ReVelle Hierarchical Maximal Covering Model

In a paper published in Management Science in 1982, George Moore and Charles ReVelle proposed a location model for siting a hierarchical system of medical facilities. In this paper we apply the Moore and ReVelle Hierarchical Maximal Covering Model to the location of medical facilities in the Kohat district in Pakistan. Optimal solutions of the Moore and ReVelle model are compared against the actual location of medical facilities in this district. We then extend the Moore and ReVelle formulation to include fixed and variable costs for siting and operating the facilities. We compare the solutions of that formulation with the results of the original Moore and ReVelle model.     

Accurate estimation of expected coverage: revisited

As noted in several studies (Batta et al., Transp. Sci. 23 (1989) 277), (Burwell et al., Comput. Opns. Res. 20 (1993) 113), (Daskin, Network and Discrete Location, Wiley, New York, 1995), (Marianov and ReVelle, Eur. J. Opns. Res. 93 (1996) 110), (Saydam et al., Socio-Econ. Plann. Sci. 28(2) (1994) 113), the accurate estimation of expected coverage is an important and open issue. Although the maximum expected coverage model is empirically shown to prescribe a robust set of “optimal” locations, earlier findings suggest that it could also over or underestimate the coverage by a significant margin. In this study, we present a genetic algorithm (GA) that combines the expected coverage approach with the hypercube model (Jarvis, Mgmt. Sci. 31 (1985) 235), (Larson, Comput. Opns. Res. 1 (1974) 67), (Larson, Opns. Res. 23 (1975) 845) to solve the maximum expected coverage location problem with increased accuracy and realism. Our findings suggest that the GA provides at least as good solutions 94% of the time making it a viable alternative to the two-step procedures stipulated earlier.     

北京市公共住房区位布局研究

本文针对城市公共住房的区位布局问题,运用Arcview GIS 3．3软件,采集了北京127个已经建设或即将建设的公共住房数据,分析出北京市公共住房区位布局存在的突出特点是北部过于集中、南部带状分布,不断向外扩张,并产生了空间失配等问题。根据以上问题,提出了在城市中心区、边缘区和新城的公共住房建设区位政策,并指出应大力发展混合住区。     

Production-location decision and free entry oligopoly: A correction

This paper shows that there is no interior solution in Mai–Hwang's 1992 oligopolistic location model with free entry when the production function exhibits constant or decreasing returns to scale. The comparative static results of the impact of a demand change on the location decision only apply to the case where the production function exhibits increasing returns to scale. It re-examines the impact of a demand change on the location decision of an oligopolistic firm and corrects the propositions derived by [C.C. Mai, H. Hwang, Production-location decision and free entry oligopoly, Journal of Urban Economics 33 (1992) 252–271. Reprinted in: M.L. Greenhut, G. Norman (Eds.), The Economics of Location, vol. I: Location Theory, Edward Elgar, Aldershot, 1995].
