In order to have a better understanding of the trend and law of convergence development of green invention technology innovation and achieve the national"double carbon"strategic goal,it is necessary to explore the measurement indexes of global green invention technology convergence,convergence trend and its relationship with output.Although the Chinese government has highlighted green invention and technology innovation,from a global perspective,the achievements of green invention and technology innovation are still significantly insufficient.Therefore this study aims to clarify the connotation of green technology,sort out the driving factors for the evolution of green technology innovation,and explore the interaction between the factors so as to accelerate the development of green technology in China.On the basis of the patent family data of global green invention technology and the existing measurement indices of technology convergence,a new series of"multiple cohesion index"indicators are proposed to measure the global green invention technology convergence in stages.Firstly,the distribution and evolution of the overall development trend,development stages and sub-fields of global green inventions are analyzed to lay a foundation for subsequent relevant research.Secondly,the sub-network files of each development stage are generated based on the co-occurrence matrix of the National Industries Classification(NIC)and the Cooperative Patent Classification(CPC).Thirdly,indices from the"Multiple Cohesion Measures(MCM)"series are selected in the cohesion analysis method to measure the technology convergence at each development stage,and get the development trend of green invention technology convergence.Lastly,the relationship between the convergence and output of global green inventions and technologies is explored by using the Pearson correlation analysis and regression analysis to explore the relationship between them.In the empirical analysis,this paper explores the relationship between global green invention technology convergence and patent output based on the quantity of invention patent outputs.477410 patents related to green invention technology are sorted out from the United States Patent and Trademark Office(USPTO).According to the annual numbers of invention patents,global green invention technology can be divided into five stages of development,and the overall trend shows a trend of rapid growth.The period from 1880 to 1919 was the embryonic period,and the speed of technological development was relatively slow,with the annual number of inventions less than 300;the period from 1920 to 1964 witnessed slow technological development,and the development was gradually accelerated;the period from 1965 to 1997 was a period of technological growth,with an annual number of inventions ranging from 1500 to 5000;from 1998 to 2009,the technology grew rapidly,and the annual number of inventions was basically between 6000 and 7000;since 2010,green technology has entered a period of rapid growth,and the annual number of inventions has exceeded 11000.From the perspective of the sub-field distribution of green technology,the global green invention technology mainly involves nine sub-fields with the energy sub-field up to 36.4%.In terms of the technology convergence of green inventions,the"multiple cohesion index"is adopted to measure the global technology convergence of green inventions in stages,and the results show that the convergence of green inventions is increasing over time.Through two groups of analysis on the interaction between global green invention network density and patent output,convergence index and patent output,it is concluded that technology convergence has a positive interaction with the output of green invention technological innovation achievements.Given the interactions of R&D design,organizational management and institutional innovation,China's green innovation should be promoted on the level of technological innovation,and innovation of key and pioneering technologies should be paralleled;the inter-disciplinary communication and interaction should be promoted at the level of discipline construction;at the level of talent training,it is essential to establish a wide-caliber talent training structure as soon as possible,speed up the training of compound talents,and provide more powerful guarantee for the development of the green industry.
