The Cumulative Effect of High Technology Industry's Innovation Performance in China:An Empirical Analysis Based on Phases and Lags

Zhao Yulin;Hu Yan;School of Economics,Wuhan University of Technology;  
From the perspective of innovation process,the innovation process of China's HTI can be divided into three stages,including the formation of scientific and technological achievements,the formation of commercial value,the formation of economic benefits.By finding the lag year and cumulative ratio,we study the cumulative effect of innovation performance of China's high-tech industry.The empirical study finds that the cumulative ratio of HTI's innovation input appears as inverted U-shaped curve,increases before the lag year,decreases after the lag year,and reaches an maximum value of 66.47% at the lag year.And the lagged effects of HTI's innovation performance appears as inverted U-shaped pattern over innovation phase.Both the lagged effect and cumulative effect of HIT's innovation performance in China during the formation of commercial value are stronger than that of the formation of scientific and technological achievements,and there is no lagged effect or cumulative effect during the formation of economic benefits.Therefore,the investment ofinnovation capital should be further increased during the formation of scientific and technological achievements and commercial value,and the innovation capability of high-tech industries should be nurtured by cumulative effects to enhance their innovation performance.Further,in order to optimizing the existing evaluation criteria,we should distinguish different phases of innovation,different lag of variables and the corresponding cumulative effects when evaluating the innovation efficiency of HTI.
