以中国为案例,对1989-2010年样本区间内竞争情报与经济增长的关系进行实证性研究。首先通过单位根检验考察变量的平稳性;其次,通过应用协整检验的方法分析变量的长期均衡特征;最后,通过应用格兰杰因果检验方法对变量之间的因果关系进行研究。结果表明,在1994-2010年样本区间内竞争情报年度论文数量增长与经济增长之间存在长期的均衡关系,把时间序列扩展到1989-2010年,则无这种长期均衡。因果关系分析发现,竞争情报论文年度数量增长与经济增长之间没有单向因果关系,也不存在互为因果的反馈性联系。
Taking China as an example, this paper conducts an empirical study on the relationship between competitive intelligence and economic growth in the 1989-2010 sample interval. Firstly, the unit root test is used to examine the stationarity of the variables; secondly, the co-integration test is used to analyze the long-term equilibrium characteristics of the variables; finally, the causal relationship between the variables is studied by applying Granger causality test. The results show that there is a long-term equilibrium relationship between the number of annual competitive intelligence papers and the economic growth in the 1994-2010 sample interval. When the time series is extended from 1989 to 2010, there is no such long-term equilibrium. Causal analysis shows that there is no one-way causal relationship between the number of competitive intelligence papers and the economic growth in the year, and there is no feedback relationship between them.
