创新与经济增长:基于区域面板数据的bootsrtap格兰杰因果关系检验

Innovation and Economic Growth:A Regional Panel Bootsrtap Granger Causality Test

以专利授权量作为创新产出指标,应用面板数据的bootstrap格兰杰因果关系的Wald检验方法,在似不相关回归系统下,检验了我国长三角地区专利与区域经济增长之间的格兰杰因果关系。研究结果表明,浙江和上海两省市发明专利与经济增长之间存在双向格兰杰因果关系,江苏省具有发明专利授权量对经济增长的单向因果关系,而安徽省两者之间不存在因果关系。另外,实用新型和外观设计专利与经济增长在所有省市都不存在任何方向的因果关系。

With patent as indicator of innovation output,We applies the panel bootstrap Granger causality test based on wald statistics and seemingly unrelated regression system,tests the causality relationship between innovation and economic growth in the region of Yangtze River Delta.The results show that there is a two-way Granger causality between invention patents and economic growth in Zhejiang and Shanghai.Jiangsu Province has a one-way causality from invention patents to economic growth,while Anhui Province has no any causality between them.In addition,there is no causal relationship between utility model or design patents and economic growth in all provinces.
