国际化是否有助于企业提高绩效？本文回顾了已有文献中关于企业的国际化程度与企业绩效关系的各种不同观点——两者正相关、负相关、倒U形关系、U形关系、水平S形关系、N形关系、甚至不相关,其各自的理论与实证依据,以及中国的相关研究。本文提出两者关系差异结果来源于三方面：1.模型形式的确定：即主关系模型为线性（正相关或负相关）、二次方（倒U形或U形）还是三次方（水平S形或N形）;2.指标体系的构建：即解释变量＂国际化＂和被解释变量＂企业绩效＂的指标选取与合理测量,其中国际化的测量方法主要有国际化深度指标、国际化广度指标、国际化复合指标三种,企业绩效的测量方法主要有会计指标、市场指标、综合指标三类;3.调节变量的纳入：国际化—企业绩效的关系除受国际化阶段和测度方式影响外,还受宏观层面的投资区域、投资产业、投资母国、东道国制度,及企业层面的进入模式、国际化节奏、产品多元化、无形资产投资等调节因素影响,选取合适的调节变量进入主关系模型,也将是本问题研究的重要突破点。本文据此建立了一个揭示＂国际化—企业绩效＂关联机制的融合性理论框架,为后续研究奠定工作基础和提供参考启示。

英文摘要：

Does inter nationalization help f ir ms improve their performance？ This is an important debate in the global strategic management research. First of all this paper reviews various answers to this question： Internationalization and firm performance are positively correlative, negatively correlative, inverted U shape relation, U shape relation, S shape relation, N shape relation, or non-correlative, along with their theoretical and empirical supporting reasons, and the covering studies in China. This paper presents that the differences of above results come from three aspects, and these are three key aspects for constructing an eclectic theoretical framework for this research： The first one is the ascertaining of the model form, that is to say, the main effect of internationalization and performance relation is linear（including positively correlative or negatively correlative）, squared / quadratic（including inverted U shape or U shape）, or cubic / sigmoidal（horizontal S shape or N shape relation）. The second is the constructing of appropriated indicators system. That means the correct indicators＇ choosing and measuring of independent variable ＂internationalization＂ and dependent variable ＂firm performance＂. Generally speaking, the indicators of internationalization include sales-based measures for international depth, subsidiary-based measures for international breadth, and synthetic measures by multiple indices; the indicators of firm performance include accounting-based indicators, market-based indicators, and composite-measure indicators. The third is the moderators＇ bringing into. Besides international phase and measurement, the relation of internationalization and performance is inf luenced by macro factors such as investment area, investment industry, home country, host country institutional arrangement, and firm factors such as entry mode, international rhythm, RD investment, product diversification. Hence, choosing appropriate moderators and entering them into the main relation
