The Evaluation On Technology Innovation Efficiency Of Patent-Intensive Industries

Technological innovation is an inexhaustible source of regional and enterprise development,and guarantee fundamentally for the industry to obtain a competitive advantage.Patent-intensive industries,as knowledge-intensive and technology-intensive industries,have become the most active areas of technological innovation in today's knowledge economy.Under the conditions of innovation of the limited resources,technological innovation efficiency is bound to affect the late development of patent-intensive industries.Therefore,the accurate identification of patent-intensive industries and the evaluation of its technological innovation efficiency has become an urgent problem to solve.This paper firstly identifies the patent-intensive industries from 2006 to 2015 from the aspects of patent stock,patent increment and R&D intensity.Secondly,it adopts the literature research method and the comparative analysis method to construct the efficiency model and its evaluation index of patent-intensive industrial technology innovation.And then uses the two-stage chain-related DEA model to evaluate the technological innovation efficiency of the industry from 2006 to 2015.Finally,the countermeasures and suggestions are put forward to improve the efficiency of technological innovation.Research shows:(1)During the period 2006 to 2015,seven industries are identified as patent-intensive industries,such as,"Chemical raw materials and chemical products manufacturing","Pharmaceutical manufacturing industry","General equipment manufacturing industry","special equipment manufacturing industry","Electrical machinery and equipment Manufacturing industry","computer,communications and other electronic equipment manufacturing industry" and "instrument manufacturing industry ".The other manufacturing industries are identified as non-patent-intensive industries.(2)In the technology development stage,the technical efficiency of each industry under the patent-intensive industry is basically in the high efficiency state throughout the research period,and in the late time,the low efficiency is the main reason for the low technical efficiency.In the stage of technological transformation,the technical efficiency of each industry under the patent-intensive industry is basically at a low level of inefficiency throughout the study period,and the pure technical efficiency has always been a key factor in hindering the technical efficiency of the vast majority of industries.In the stage of technological development and technological transformation,the technical efficiency level of each industry under the patent-intensive industry is different,but it is basically in the state of diminishing scale,and there is serious investment redundancy.(3)During the period from 2006 to 2015,the technical efficiency of the patent-intensive industry has been greater than that of the non-patent-intensive industries in the technology development stage,and the gap has increased year by year.In the technological transformation stage,technical efficiency in patent-intensive industry is always lower than the non-patent-intensive industries,and the gap narrowed year by year.The transformation of technological achievements is a key stage in suppressing the efficiency of the overall technological innovation of patent-intensive industries.
