以我国装备制造业20家上市公司的市场经营数据为样本,从市场效率、市场份额、产品差异等角度考察竞合对市场拓展产生的影响。研究发现,竞合行为的模式不同对装备制造业市场拓展产生的影响也不同,竞合行为并不会必然使双方都获得收益。从分析数据看,以关联联盟形式进行的竞合更能导致企业相对市场效率的改变,以规模联盟形式进行的竞合更有利于产品差异化,而在市场进入方面两种形式的竞合没有显著差异。显然,装备制造业如何理性选择竞合行为和实施策略以参与国际竞争成为亟待解决的问题。  相似文献

Summary. Conventional wisdom holds that product market competition disciplines firms into efficiency of operation. However, in a well known paper, Martin (1993) has shown that in a linear Cournot setting (with costs determined first and product market competition taking place in a second stage) the exact opposite obtains – a larger number of firms competing in the market implies lower firm efficiency. The note clarifies further the links between market structure and efficiency. Specifically, it argues why (and how) the result derived by Martin (1993) depends upon the assumptions made regarding the structure of demand and nature of conjectures held by firms as to their rivals' behavior. An illustrative counter-example (with Bertrand behavior and non-linear demand) in which entry increases efficiency is provided as well.

Using an extensive micro-price data of 266 retail goods and services across US, EU and OECD cities between 1990 and 2005, we study characteristics of geographic dispersion of deviations from the Law of One Price. We find that the magnitude of price dispersion is a function of the characteristics of both the type of good and set of locations under examination. Higher share of non-traded inputs and lower tradability of goods are both found to contribute to geographic price dispersion, with the former typically dominating in explanatory power. The role of tradability of good in accounting for the price dispersion is more significant as we move beyond an economic geography, while non-traded input level matters relatively more if we move to the interior of this geography. Our evidence suggests that the models of real exchange rates should incorporate the classical distinction between traded inputs and local inputs as well as a role for relative markups and traditional trade costs.  相似文献

ABSTRACT

Despite extensive discussion about the relationship between market competition and innovation performance, the impact of market competition on the innovation efficiency of high-technology industries in a transitional economy is still unclear. The article is based on panel data of 17 subsectors of China’s high-tech industry spanning the 2001–2016 period. Using stochastic the frontier analysis model, we empirically test the impact of market competition on two-stage innovation efficiency from the perspective of the industry. The results indicate that market competition and firm scale have positive and significant effects on the efficiency of two-stage innovation, the effects of industry export intensity and government intervention on R&D efficiency are negative, but the effects are different for the efficiency of the commercialisation of technology. Based on the results of the empirical analysis, this paper compares the trends and the differences between R&D efficiency and commercialisation efficiency, and then uses cluster analysis to reclassify China’s high-tech industries into three categories, thus revealing the disconnect and imbalance within China’s high-tech industries. At the end of the article, we present some possible policy recommendations.  相似文献

This paper examines strategic competition behavior in heterogeneous market structure where both conventional offline and online firms coexist in equilibrium and draws strategic implications with some remarks on welfare. Research on the price competition between conventional offline and online firms has been done through empirical approaches; however, the results are conflicting. This paper reconciles the existing conflicting empirical findings on price levels between conventional offline and online firms through a theoretical approach. We find that as the online market matures, prices in both conventional and online firms drop, and the price in the online firm can be higher than that in a conventional offline firm. Furthermore, if convenience associated with the online increases, the online price tends to exceed the conventional offline price.  相似文献

The paper investigates price dynamics under market liberalization, with a focus on the effects of lowering price floors. We analyze price dynamics by specifying and estimating a dynamic Tobit model under time-varying volatility, where the market price is censored by a government-set support price. The model is applied to the U.S. butter market over the last three decades. The econometric results show how the price support program affects both expected prices and the volatility of prices. It is found that the censoring effects of a price support program can be significant and large even if the price support is set relatively low.

研发市场是经营者在特定产品和技术竞争中形成的市场范围。由于研发活动的不确定性,反垄断执法机关在界定研发市场时难以准确厘定市场边界,更深层次的原因在于维持竞争与激励研发的关系尚不明晰。研发竞争中的垄断行为难以通过相关市场界定的方式判断其违法性,需要结合具体案情和市场条件,动态分析涉案行为是否损害产品或技术研发竞争。  相似文献

场外交易市场建设初期,做市商制度在各国家及地区得到普遍应用。随着市场规模的扩大,交易制度逐步演变为混合性做市商制度。2014年我国新三板市场引入做市商制度,通过对市场整体以及协议转让、做市转让两类股票样本进行比较,文章认为在政策推动、市场主体积极参与等因素作用下,新三板市场整体规模、流动性均得到快速提高,做市商制度在流动性改善、价值发现等方面具有重要作用,挂牌公司具有较强的差异性对分层管理提出了现实需求。提高流动性仍然是新三板市场的重要任务之一,文章认为需要从制度、需求、供给、监管四个方面进行采取积极措施。  相似文献

In this paper we empirically explore outsourcing decisions of peripheral services using information from a data set of 926 Spanish manufacturing plants. We find that increases in outsourcing of peripheral services are positively correlated with increases in the plant׳s market share as well as increases in product market competition and product prices. These findings are robust to controlling for whether plants belong to single-plant or multi-plant firms. These patterns are consistent with a strategic shift in the allocation of attention to core manufacturing activities, and are at odds with traditional TCE and PRT theories of vertical integration.  相似文献

This study evaluates one of the most important emerging markets, India (Bombay Stock Exchange and Indian National Exchange), for its efficiency and for its potential to offer diversification benefits to international investors. Market-wide tests include; 1) contemporaneous relationship, 2) Granger type causality and 3) day-of-the-week effect. Tests on individual Indian stocks include: 1) panel estimation of Granger causality, 2) stock-by-stock estimation of Granger causality and 3) runs test. In sum, Indian markets are well integrated with the international equity markets, a characteristic that lowers the international diversification benefits. While day-of-the-week effect is an international spillover, it may be possible to predict individual Indian stocks' returns through causality with international equity markets and through momentum trading techniques.  相似文献

This study examines whether and how macroeconomic performance competition is related to investment at firm level. We use GDP competition as a proxy of dynamic macroeconomic conditions. We find that the effect of GDP competition on firm investments is significantly positive. We also find that GDP competition destroys investment efficiency significantly, especially by increasing overinvestment. Further tests show that GDP competition is more likely to affect the investment decisions of firms controlled by governments and firms located in regions with low marketization. In addition, our analyses reveal that the provincial officials facing competitive pressure are more likely to be promoted if firm investments accelerate. We use alternative proxies to measure GDP competition and find similar results that support our inference. Our findings support the notion that GDP competition of governments distorts investment behaviour. The present paper also elucidates investment problems and dilemmas faced by emerging economies.  相似文献

The United States and other nations rely on consumer choice and price competition between competing health plans to allocate resources in the health sector. While a great deal of research has examined the efficiency consequences of adverse selection in health insurance markets, less attention has been devoted to other aspects of consumer choice. The nation of Switzerland offers a unique opportunity to study price competition in health insurance markets. Switzerland regulates health insurance markets with the aim of minimizing adverse selection and encouraging strong price competition. We examine consumer responses to price differences in local markets and the degree of price variation in local markets. Using both survey data and observations on local markets we obtain evidence suggesting that as the number of choices offered to individuals grows, their willingness to switch plans given a set of price dispersion differences declines, which allows large price differences for relatively homogeneous products to persist. We consider explanations for this phenomenon from economics and psychology.  相似文献

论文基于2005—2009年中国A股上市公司年报数据的实证研究发现,当投资于发放现金股利的公司股票时,机构投资者持股比例与上市公司股票换手率、股票收益波动率、股价同步性等反映和衡量股票市场稳定性的三个渐次递进维度的指标都显著负相关;而当投资于不发放现金股利的公司股票时,机构投资者持股比例与衡量股票市场稳定性的指标显著正相关抑或不具有显著影响关系。这些结果表明上市公司的现金股利政策直接影响着机构投资者是选择长期的价值投资行为还是进行短期频繁的投机炒作,进而影响机构投资者稳定股票市场功能的有效发挥。论文的研究结论对于股票全流通时代发展机构投资者、引导投资者的长期价值投资行为以促进中国资本市场的健康稳定发展具有重要的启示和政策意义。  相似文献
