广义虚拟经济视角下中国汽车制造业创新效率研究

Research on the Innovation Efficiency of China's Automobile Industry from the Perspective of Generalized Virtual Economy

将汽车制造业研发创新活动纳入广义虚拟经济系统,基于制造业2008-2014年的面板数据,运用DEA方法实证研究中国汽车制造业的创新效率。研究发现:汽车制造业的广义虚拟经济研发创新效率低于制造业整体水平,处于28个制造业细分行业的中等位置;仅仅考虑专利为创新产出而不考虑发明专利为创新产出会高估汽车制造业的创新效率。

Bring the R＆D activities of automotive industry into the system of generalized virtual economic, this paper empirically studies the innovation efficiency of China＇s auto industry by using DEA method, based on the panel data of manufacturing industry from 2008 to 2014.The results shows that： the innovation ef- ficiency of auto industry within generalized virtual economy is lower than that of manufacturing, and it is in the middle position of 28 sub-sectors; only consider the patent innovation as output without considering the invention patent innovation as output will overestimate the innovation efficiency of automobile industry.
