经济增长、结构调整的累积效应与资本形成——当前经济增长态势分析 总被引:30,自引:1,他引:30
1990年以来 ,特别是 2 0世纪 90年代中后期 ,中国的经济结构发生了重大调整 :基础设施的投入奠定了城市化的基础 ,工业化在消费和出口的拉动下逐步升级。中国经济增长开始由工业化单引擎发展到工业化与城市化的双引擎。由低价工业化到高价城市化的转化以及与之相应的资金流程与资本形成方式的变化 ,一方面引起近年来中国经济的快速发展 ,另一方面也对未来中国经济的持续增长形成挑战。通过政府体制、金融体系和财税体制的进一步改革 ,完善资源配置方式 ,将是应对挑战、保持中国经济持续增长的保证。 相似文献

In recent work on non-cooperative network formation star-shaped networks play an important role. In a particular theoretical
model of Bala and Goyal (2000) center-sponsored stars are the only strict Nash networks. In testing this theoretical model,
Falk and Kosfeld (2003) do not find experimental evidence that players select the center-sponsored star. Based on a slight
modification of Bala and Goyal’s model, we design a network formation experiment in which, depending on link costs, periphery-sponsored
stars and the empty network are the only strict Nash networks. We observe that almost all groups not only reach a strict Nash
network once but also switch the center player in periphery-sponsored stars several times. The main innovation in our experiment
is to use a continuous time framework which we believe to be a more realistic setting to study behavior in network formation
situations and which makes coordination on stars much easier than simultaneous strategy adaptation in discrete time.

社会资本外部性的经济分析——以信任关系为例 总被引:2,自引:0,他引:2
以往理论研究与经验研究均指出社会资本具有正面的效应,但对这种效应是怎样取得的并无共识.我们尝试建立一个不完全信息动态博弈模型,说明社会资本-信任如何产生正的外部性,亦即产生超出个体理性计算之外的利益.我们的分析得出这样的结论,在一个多人互动的环境中,能否达到彼此合作或彼此信任,虽然会受到欺骗者所遭到的惩罚与欺骗利益多少的影响,但主要受到所处环境中具有社会资本者人数比例的影响.因此,可以说社会资本具有正的网络外部性,信任者人数越多,信任者所享受到的利益越大. 相似文献

I examine the formation of a specific communication network, a variant of the two-way flow model, in which agents have farsighted strategies. I show that the likelihood to form efficient networks tends to zero for sufficiently large network sizes. 相似文献

We study a dynamic duopoly model with network externalities. The value of the product depends on the current and past network size. We compare the market outcome to a planner. With equal quality products, the market outcome may result in too little standardization (i.e. too many products active in the long run) but never too much. The potential inefficiency is non-monotonic in the strength of the network effect, being most likely for intermediate levels. When products differ in quality, an inferior product may dominate even when the planner would choose otherwise, but only if the discount factor is sufficiently large 相似文献

我国商业银行营销渠道的选择 总被引:2,自引:0,他引:2
孙波 《中央财经大学学报》2003,(9):35-37
商业银行营销渠道的选择是一项重要的战略决策,它会极大地影响其经营业绩和成本水平。目前,我国商业银行的营销渠道还比较狭窄,基层网点功能单一,服务手段落后。今后,商业银行要根据目标市场客户的需求,积极开发新的金融产品,大力整合、开发和拓宽营销渠道。 相似文献

Complementarity, coordination and compatibility: The role of fixed costs in the economics of systems
Dominique Desruelle Gérard Gaudet Yves Richelle 《International Journal of Industrial Organization》1996,14(6):747-768
We analyze industry equilibrium and incentive to compatibility when goods produced by different producers generate utility only when consumed as component parts of a system. We assume the presence of two systems, each composed of some basic component and a set of differentiated complementary products. The combination of complementarity between the two components of the system and of fixed costs in the production of the complementary product results in a form of network effect. We focus on the role played by the size of the fixed costs in the production of the complementary products in determining the size of this system effect and, by this means, the structure and types of equilibria that may be observed: monopolistic or duopolistic, symmetric or asymmetric. We also highlight the consequence of the same fixed costs for the private and social incentives to render the systems compatible. 相似文献

Do converters facilitate the transition to a new incompatible technology? A dynamic analysis of converters 总被引:1,自引:0,他引:1
Jay Pil Choi 《International Journal of Industrial Organization》1996,14(6):825-835
This paper analyzes the process of transition in standards between incompatible technologies when converters are available. Contrary to a common presumption that converters facilitate the transition from an old technology to an otherwise incompatible new technology, I find circumstances in which the possibility of transition is blockaded by the existence of converters. In the welfare analysis of converters, a distinction is made between ex ante and ex post efficiency effects. Finally, I also analyze the equilibrium behavior in the provision of converters and compare it to the socially optimal outcome. 相似文献

We show that banks with shared social connections partner more often in the global syndicated loan market and that central banks in the network play dominant roles in various interbank transactions, indicating that social connections facilitate business connections. However, more centralized banks in the network also contribute significantly to the global systemic risk. Moreover, we find the soft information generated by social networks is particularly valuable when potential partners operate under different accounting and regulatory standards. Finally, we show that the recent banking crisis significantly limited the positive soft information effects of social networks in the global banking system. 相似文献
