【摘要】 基于2001—2017年间中国集成电路(IC)产业的专利申请数据,分别检验该产业及其3个子行业专利产出与产业绩效之间的协整和格兰杰因果关系。研究结果表明:中国IC产业的制造业、封测业的专利产出与各自销售额形成了长期均衡关系,且它们的专利申请是其销售额增长的格兰杰原因;产业专利申请总数并未与产业总销售额以及出口量形成长期均衡关系。更多还原

【Abstract】 Based on the patent application data of IC industry in China from 2001 to 2017, this paper examines theco-integration and Granger causality between the patent output and industrial performance of IC industry and its threesub-industries. The research results show that there is a long-term equilibrium relationship between the patent outputand sales in manufacturing industry and packaging and testing industry, and their patent applications are Granger’sreason for the increase in sales; in addition, the total number of patent applications in IC industry does not form along-term equilibrium relationship with the total sales volume and export volume of IC industry.更多还原
