Research On The Technological Progress Effect Of China's Service Industry With The Ability In Accessing Added Value

The new round of technological revolution and industrial transformation drive the deepening and remodeling of the global value chain,which has become an important way to achieve industrial upgrading and technological progress in China.Value added capability is an effective way to enhance the status of a country's industry and enterprises in the global value chain division of labor.At present,the service industry has become an important part of the global value chain,and it plays an increasingly prominent role in improving total factor productivity.Therefore,the new theoretical connotation and practical value will be embedded in the theoretical frontiers of value added ability into the important practical problems of the technological progress of the service industry of our country.Based on the global value chain theory and endogenous growth theory,this paper reexamines the mechanism of the effect of value added capacity on the technological progress of service industry,and uses the Chinese Statistical Yearbook and the UIBE database issued by the Institute of global value chain of University of International Business and Economics to use the global value based on the forward and backward correlation.The chain length index,the global value chain participation index based on the forward and backward correlation and the global value chain status index measure the value added ability of China's service industry and its subdivision industries,and try to put forward the research hypothesis of value added ability for the technological progress of service industry and build the value added capability embedding.The nonlinear regression model of the technological progress effect of China's service industry is used to calculate the total factor productivity and technological progress index of the service industry in China by using the advanced econometric method and data envelopment analysis method,and the effect of the technological progress of the service industry in China should be explored and analyzed.In view of the above research methods and contents,this paper mainly draws the following conclusions: first,under the framework of global value chain,the value added capability embeddedness has both negative and positive effects on the role of China's service industry,that is,the value added energy is embedded in the technological progress of China's service industry.Secondly,based on the input-output method considering the forward correlation of raw material initial input and the added value decomposition of the final product production,the value added capacity of our service industry and its subdivision industry is measured.In the observation period,the service industry and its fine sectors are based on the forward and backward correlation.The global value chain length index ranking is higher,and the global value chain participation and the global value chain status index are relatively low on the basis of the forward and backward correlation and the global value chain status index,and there are obvious industry heterogeneity in the service sector.Because of the lack of core production technology,the knowledge intensiveand technology intensive industry is lack of core production technology,which leads to the weak international competitiveness and value added ability of service industry and its subdivision industries,and the ability of independent innovation needs to be further promoted.
