Research On Technological Innovation Strategy Of LNG Marine Enterprises Based On Patent Data Mining

As an important part of China's strategic supporting industry--shipping industry,shipping enterprises play an irreplaceable role in promoting the growth of national economy.As a representative of high-tech ships,LNG ships are the focus of future development of shipping enterprises.With technological innovation becoming the theme of the development of The Times,shipping enterprises gradually realize the importance of technological innovation for their own maintenance and development as well as improving competitiveness.When enterprises carry out technological innovation activities,they can get twice the result with half the effort by formulating appropriate technological innovation strategies.Based on patent data mining,using patent analysis method,entropy-TOPSIS evaluation method,evolutionary game theory and so on,this thesis systematically studies the technological innovation activities of shipping enterprises from three aspects: the direction of technological research and development,the analysis of patent technology competitiveness and the analysis of technological cooperation innovation behavior.Finally,some feasible suggestions are put forward for the technological innovation strategy of the LNG industry.The main research contents are as follows:(1)Identification of technical research and development direction in LNG ship field.Obtains relevant patents in the LNG shipping field through PATSNAP data platform,analyzes the annual development trend,regional distribution and main patentees of the patented technology in the LNG shipping field through patent data mining with patent analysis method,and identifies the hot spots of technology research and development in the LNG shipping field.It points out the technical research and development direction of LNG field for related shipping enterprises.(2)Competitiveness analysis of patented technologies in LNG shipping field.Starting from four dimensions of patent technology scale,patent technology quality,patent technology value and patent technology collaboration,a comprehensive evaluation index system of enterprise patent technology competitiveness is constructed.Using the entropy weight and TOPSIS combination method,the patent technology competitiveness of each innovation subject in the field of LNG Marine technology research and development is analyzed.It helps enterprises to define their technical position and competitors in the field of LNG ship technology research and development,and lays a foundation for enterprises to choose technological innovation mode and R&D partners.(3)Analysis on the innovation behavior of industry-university-research technology cooperation in the field of LNG shipping.Considering the current situation that Chinese shipbuilding enterprises have weak patent technology competitiveness and universities have strong patent technology competitiveness in the field of LNG technology research and development,the development of industry-university-research cooperation is conducive to the improvement of technical competitiveness of enterprises.Based on the evolutionary game theory,a game model of technological cooperative innovation between enterprises and universities is constructed.On the basis of obtaining the equilibrium point,the influences of enterprises' requirements for technological ability of universities and profit distribution factors on the innovation strategy of industry-university-research cooperation are analyzed deeply.(4)Technical innovation strategies of LNG Marine enterprises.On the basis of the above analysis,the thesis summarizes the technological research and development direction,patent technology competitiveness and technological cooperation innovation behavior of shipping enterprises in the LNG field,and further puts forward feasible suggestions for shipping enterprises to formulate reasonable technological innovation strategies.
