Research On The Relationship Between R&D,ICT And Labor Productivity Based On Extended CDM Model

Labor productivity is highly related to economic growth,which is a landmark indicator to determine whether a country's economy has a future growth.In view of the fact that enterprises are important pillars of social and economic development,R&D and ICT investment can affect productivity through increasing innovation.Therefore,it is of great practical significance to explore the impact of R&D and informatization on enterprise productivity at micro level.In this paper,we use R&D and ICT investment as innovative input in the research data of Chinese enterprise innovation,which covers many industries.Based on the CDM model,the analytical framework of the relationship between innovation input,innovation output and labor productivity at the enterprise level is constructed.The relationship between R&D and ICT input and labor productivity is obtained through three stages of recursive analysis.The three stage equation includes innovation input equation(including R&D input decision equation and intensity equation,ICT input decision equation and intensity equation),and innovation output equation(innovation is divided into product innovation and process innovation)and labor productivity equation.At the same time,this paper also analyzes the influence of company characteristics,technology driving factors,export and other factors on R&D and ICT input and innovation output.The main results are as follows:(1)capital strength,business scale,export,technical factors and the quality of the labor force has a significant positive impact on the R&D and ICT decision,investment decision is mainly affected by the export and three technical factors on the use of foreign technology,standardization,new equipment investment.(2)the intensity of R&D investment and the intensity of ICT investment all play a significant role in promoting product innovation and technological innovation.R&D,When R&D input intensity is increased by 10%,product innovation output will increase 1.507 units,and ICT input intensity increases by 10%,and product innovation output will increase by 0.875 units.When R&D input intensity is increased by 10%,technological innovation output will increase 1.645 units,and ICT input intensity increases by 10%,and technological innovation output will increase by 0.730 units.(3)product innovation and technological innovation have a positive impact on labor productivity,and ICT can not directly affect productivity.In conclusion,R&D and ICT investment indirectly affect productivity through innovation.R&D and ICT investment increase the possibility of product innovation and process innovation,which improve the productivity of enterprises.
