单边效应

因此，本文分析了几种不同需求曲线形状下单边效应的大小，包括线性需求、等弹性需求、选择模型与Logit需求模型。

Therefore , it makes the size of unilateral effects with different sharps of the demand curves , including linear demand , isoelasticity of demand , choice models and Logit demand models .

但如何在合并审查时成功地预测单边效应一直是困扰反垄断执法者的一个难题。

However , it is difficult for antitrust enforcers to predict unilateral effects successfully in merger reviews .

本文简要地评价了古诺模型中的相关问题及其在单边效应分析中的适用性。

This thesis briefly evaluates the related issues about the Cournot model and its applicability in the unilateral effects analysis .

在产品市场上，单边效应理论主要是基于寡头垄断理论&古诺模型和伯川德模型。

In product markets , the unilateral effects theories are based on oligopoly theories : the Cournot and the Bertrand models .

第三个扩展就是建立了四阶段动态博弈模型来考虑了新企业进入对单边效应的影响。

The third extension is to build a four-stage dynamic game model to consider how new enters affect the unilateral effects .

尽管单边效应的理论和分析方法都在不断完善改进，但至今仍有许多争议，仍是一个值得研究的领域。

Although the theory and analytical method of unilateral effects is improving , there are still some controversies and need to do much more works .

在推导过程发现，单边效应的大小与需求曲线的形状有着重大的联系。

During the process of derivation , it finds that the size of the unilateral effects and the shape of the demand curve has a significant relationship .

差异产品市场横向兼并单边效应分析技术在最近的十几年有了迅速发展。

The last more than a decade has witnessed the dramatic developments of approaches to analyzing the unilateral effects due to a proposed horizontal merger in the differentiated products .

首先，在差异产品市场上，建立伯川德模型，在最简化的情况下推导了单边效应出现的可能性及大小。

Firstly , it builds the Bertrand model in the differentiated product markets , and deduces the possibility and size of the unilateral effects in the most simplified case .

本文通过一个虚构的中国国内服务器产业兼并的例子，探讨了如何用这种兼并模拟方法评价差异产品产业横向兼并单边效应的问题。

This paper , through a hypothetical merger in server industry in China , examines how to assessing the unilateral effects of a horizontal merger in differentiated products industries by using merger simulation .

但是随着单边效应理论和经济计量技术的发展，以及数据越来越容易收集，用并购模拟进行分析渐成一种趋势。

With the development of unilateral theory and econometric techniques , so as the availability of market data is increasing , there is an obvious trend to use merger simulation method to analyze merger .

在对案件进行定性分析的基础上，应在市场界定、市场份额及集中度、单边效应分析中明确量化指标，进行更精确的定量分析。

At the basis of qualitative analysis , we should clear quantitative index in the market definition , market share and concentration , unilateral effect analysis , the more accurate quantitative analysis should be taken .

在分析经营者集中引起的反竞争效应时，执法机构可以构建经济模型来量化并购引发的单边价格效应。

When we analysis the anti-competition effect which caused by the concentration , agencies can construct economic model to quantitative unilateral effect .
