国家标准化建设对产品质量发展的影响——基于1990—2010年时间序列数据的实证研究

National standard construction's influence on product quality——demonstration research based on 1990-2010 time series data

本文利用1990-2010年的时间序列数据,用动态计量分析方法,对国家标准化建设与产品质量发展之间的关系进行了实证研究。结果表明:国家标准化建设是产品质量发展的重要影响因素,二者之间存在长期稳定的均衡关系;国家标准数量与产品质量发展之间是单向因果关系,即国家标准数量会影响产品质量的提升,但产品质量提升并不是国家标准化建设的原因;国家标准化建设对产品质量的影响中,短期作用要大于长期作用。

This paper explores the causality between the state standardization and product quality, using annual data for the period of 1990-2010. The results show that there are long-term stable equilibrium relations between the state standardization and product quality. Empirical results also suggest that product quality does not appear to Granger-cause state standard, while state standard affects product quality. It is also found that, the short-term effect of the state standardization on product quality is greater than the long-term effect.
