Research On The R&D Efficiency Of High Technology Industry Based On The DEA Approach With Double Frontiers

High tech industry with the development of science and technology era,China gradually become a strategic industry,the main characteristics of high technology industries include development of high investment,high profit and innovation risk degree higher,thus the vitality of high tech industry mainly depends on the ability of technological innovation.In recent years,China government and enterprises to increase investment in technological innovation,increase investment also brings the rapid increase in the amount of output,technological innovation and the ability to significantly enhance the efficiency of technological innovation is also significantly improved,investment is located in marginal increases or decreases,the distribution situation and recognize the gap in various provinces and industries technological innovation efficiency on the regional development strategy and resource is very important.Therefore,this paper will use the double frontier data envelopment analysis,a reasonable measure of the efficiency of technological innovation,this paper compared the decision-making unit evaluation unit respectively with the "optimal" and "worst",China of high technology industry of 22 industries and 26 provinces and cities in the optimistic and pessimistic efficiency measurement,comprehensive results expressed by geometric average efficiency.The results show that the China high technology industry 22 industry R&D innovation efficiency differences and maintain low input at the same time,should focus on promoting the transformation of scientific and technological achievements;Chinese technology innovation efficiency of high tech industry regional overall showing "high in the East and low in the West" pattern,high technology industry unbalanced development is conducive to the formation of innovation cluster,further improve the comparative advantage,avoid high technology industry blossom everywhere.
