Abstract:

Based on the innovation process framework, this paper decomposes the innovation process into new technological R&D stage and transformation stage and uses improved two-stage network DEA model to measure the overall efficiency, technological R&D efficiency and transformation efficiency of regions in five typical high-tech manufacturing industries in China. This paper investigates the changing trend and gap of innovation efficiency of three provinces in Northeast China by comparing innovations efficiency of these three provinces with other regions. It also reveals the main factor which restricts the increase of innovation efficiency in the three provinces. The result shows that, the innovation efficiency of the three provinces presents discrete development trend, instead of converging to a higher level. The innovation efficiency gap between the three provinces and other regions widens gradually, and there is bigger innovation efficiency gap between the three provinces and other regions in the industry with higher level of marketization.

Key words: three provinces in Northeast China, high-tech manufacturing industry, innovation efficiency, two-stage network DEA model
