竞争战略对企业绩效滞后性及持续性的影响——以沪市上市公司为例

The Time-lag Effect and Continuity Effect of Competitive Strategies on Firm Performance——Taking Shanghai-listed Companies as an Example

本文采用波特(Porter)的基本竞争战略分类方式,借助验证性因子分析判断企业实施竞争战略的类型,并在此基础上建立向量自回归模型,通过脉冲响应函数分析竞争战略对企业绩效滞后性及持续性的影响。研究结果表明:竞争战略影响企业绩效存在滞后性,且差异化战略的滞后期相对较长;竞争战略影响企业绩效存在持续性,且实施差异化战略可以获得更为持久的竞争优势。

Using basic classification of Porter＇s competitive strategies,with the confirmatory factor analysis（CFA） to judge types of enterprises＇ competitive strategy,this paper establishes a vector autoregression model（VAR）,and analyses the time-lag effect and the continuity of competitive strategy performance by the impulse function.The results show that：？there is some lag when the competitive strategy affects corporate performance,and the lag period of the differentiation strategy is longer than that of the low cost strategy;competitive strategy affects the continuity of corporate performance,and the implementation of differentiation strategy can get stronger competitive advantage.
