Study On The Relationship Between R&D Structure Indexes And Innovation Performance

Under the background of economic globalization,the competition of the comprehensive national strength is becoming more and more challenging.The most important part of the competition is the competition of innovation ability.China is the biggest developing country and the eighteenth national congress of the CPC puts out an idea that China must implement a strategy of innovation-driven development.This article chooses five important urban agglomerations and high technology industry to do some research on innovation.In this paper,the R&D structure refers to the use structure and source structure.We divide the R&D expenditure into labor service expenditure and equipment expenditure based on their use and we also divide R&D expenditure into enterprise fund and government fund based on their sorce.The innovation performance can be divided into two parts,the economic performance of innovation and the efficiency performance of innovation.To be specific,the economic performance of innovation is measured by the proportion of new product sale in total income and the the efficiency performance of innovation is the input and output efficiency.With respect to the economic performance of innovation,we study on the panel data of high technology industry in five major urban agglomerations from 2009 to 2015.After regression we found that labor service expenditure and economic performance show significant positive correlation but equipment expenditure and economic performance show no significant correlation.Homoplastically there is significant positive correlation between enterprise fund and economic performance but there is no significant correlation between government fund and economic performance.The last but not the least,high-tech industry can be divided into five segments and there are big differences in these five segments.About the efficiency performance of innovation,this paper used Date Envelopment Analysis method to discuss the innovation efficiency of the five major urban agglomerations.DEA is very suitable for evaluating the effectiveness of some departments or units that have multi inputs and multi outputs.This model takes thirteen regions in the five major urban agglomerations as decision making units.The two outputs are new product sales and the numbers of patent application and the four inputs are the enterprise funds,government funds,the nuber of R&D personnel and technology import costs.The results show that Pearl River Delta urban agglomeration's innovation efficiency is the highest one,Chengdu Chongqing UrbanAgglomeration's innovation efficiency is the second one,Yangtze River Delta urban agglomeration's innovation efficiency is the third one,Beijing Tianjin urban agglomeration's innovation efficiency is the fourth one and the innovation efficiency of urban agglomeration in the middle reaches of Yangtze River is the last one.
