| Since the reform and opening up,China’s market-oriented process has accelerated,and innovation investment has increased year by year.How the market-oriented process affects the improvement of innovation efficiency has become a hot topic.In this regard,based on the data of 31 provinces(autonomous regions,municipalities directly under the central government)in 2003-2017,the innovation process is divided into technological innovation stage and achievement transformation stage.First,the DEA malquist index method is used to measure the innovation efficiency of various regions in China.It is found that: the comprehensive efficiency of China’s technological innovation stage shows a certain decline trend,but the comprehensive efficiency shows an increase trend in the stage of achievement transformation;in the stage of technological innovation efficiency,the decrease of technological progress index hinders the improvement of the comprehensive efficiency;and in the stage of achievement transformation,the technical progress index The increase in comprehensive efficiency is also significantly promoted.Second,the convergence analysis of the two-stage efficiency shows that: in China,the innovation efficiency in the two stages is generally convergent,but the convergence rate of innovation in different regions is different;in the stage of technological innovation,the efficiency convergence in the eastern region is better than that in the central and western regions;and in the stage of achievement transformation,the efficiency convergence in the central and western regions is better than that in the eastern region.Third,through the construction of the common panel regression model,it is found that: marketization can promote the innovation efficiency in two stages of innovation,especially in the stage of achievement transformation,the role of marketization is more prominent,while in the stage of technological innovation,there are certain regional differences in the role of marketization on innovation efficiency, and in the eastern region with higher marketization degree and marketization as a whole The lower degree of the whole western region has a significant role in promoting,but not in the central region.Fourth,the interaction coefficient of market-oriented index and innovation resource endowment index is significantly positive,indicating that in the two stages,market-oriented has a positive regulatory effect on innovation resource endowment,and innovation resource endowment plays a stronger role in promoting innovation efficiency in regions with higher degree of market-oriented.Fifthly,through the analysis of the threshold effect of the two stages,it is found that the innovation resource endowment has a significant inhibitory effect on the efficiency of technological innovation when it is in the stage of technological innovation and the level of marketization is at a lower threshold level,whereas the innovation resource endowment has a promoting effect on the efficiency of technological innovation when the level of marketization is at a higher threshold level. |
