The Development Of Production Service Industry In Jinan Under The Background Of New And Old Kinetic Energy Transformation Research On The Impact Of Economic Growth

The service industry economy was launched in the 1950s and has rapidly achieved development in the world.It has become an important source of economic growth and a major channel for providing jobs.In 2013,the proportion of China's tertiary industry surpassed the secondary industry for the first time,marking the transformation of the entire economy from an industrial economy to a service-oriented economy.At the end of 2018,the service industry has supported half of the country.The wide application of new technologies represented by the Internet has led to the rapid development of the production services industry,such as e-commerce,mobile payment,paperless media,and e-finance,which not only subverts our recognition of traditional production.Knowing that it has also effectively changed people's way of life,the producer service industry has become a new hot spot to lead economic growth and a new force to stimulate economic growth.At present,Shandong is a demonstration area for the transformation of new and old kinetic energy in the country.Jinan City,as the provincial capital of Shandong Province,vigorously develops the productive service industry.It is the inherent requirement of the conversion of old and new kinetic energy,and it is also the construction of a modern market dominated by productive services and advanced manufacturing.An important measure of the industrial system.Under the new economic normal,the dynamic mechanism for promoting economic growth has always been a hot issue for scholars.In this paper,the related theories of the production service industry and the transformation of old and new kinetic energy are systematically combed.Comprehensively using the description statistics and measurement models to try to explain the new and old kinetic energy conversion background,the productive service industry can become a new kinetic energy to promote economic growth.The productive service industry is characterized by high knowledge intensiveness,rapid development and innovation.It can promote productivity and spillover effects through the advancement of science and technology,promote value chain upgrade,industrial integration effect,promote industrial structure transformation,absorb employment efficiency and promote social stability.The five mechanisms of action of scale agglomeration effect and regional competitiveness have an impact on economic growth.Based on the connotation of the new and old kinetic energy conversion,this paper establishes the theoretical framework of the impact of productive services on economic growth under the background of new and old kinetic energy conversion.On the basis of theoretical research,the use of descriptive statistical tools is used to summarize the main performances of Jinan City in 2005-2018,especially in 2018,Jinan City's productive service industry to promote the transformation of new and old kinetic energy to promote economic growth.Using the three-layer multiple linear regression equation,first establish the model of the production service industry and these five aspects of the mechanism,and then follow the Cobb Douglas function to establish the above five aspects of the mechanism of action and the regional total output relationship model to verify these five effects.The impact of the mechanism on economic growth,further analysis of the role of the internal industries of the producer service industry in the total output of the region,from the relatively rigorous logical chain to prove that the productive service industry can positively promote economic growth through the above five mechanisms of action.Role,productive services can become a new kinetic energy to lead economic growth.And the second-order exponential smoothing method is used to predict the future trend of the production service industry in Jinan,and the shortage of the production service industry in Jinan is analyzed.On the whole,the scale of the production service industry in Jinan has increased year by year,the proportion of the production service industry in the service industry has been basically stable,the internal structure has been gradually optimized,and the contribution to the regional total output has been obvious.The research results show that the producer service industry plays an active role in adjusting the industrial structure,improving the productivity of the secondary industry,promoting employment,improving the level of urbanization,and promoting scientific and technological progress.The financial industry,the wholesale industry,information transmission,software and information technology services.With a clear linear positive relationship with GDP,the development of productive services will promote economic growth.It is expected that by 2021,Jinan's productive service industry is expected to exceed the 300 billion mark,but compared with advanced cities,the problem of insufficient total is still relatively prominent,the industrial base is relatively weak,external demand is insufficient,and the institutional mechanism is restricting development.major factorFinally,combining the background of new and old kinetic energy conversion and the problems and research conclusions of Jinan's productive service industry,it is proposed to promote the service level from low to high based on the demand dynamic level;based on the factor supply level,promote the investment drive to the innovation drive;Based on the industrial dynamics level,it will promote the transformation of scale expansion to industrial integration;based on the regional economic development level,it will promote the conversion of disorderly competition to industrial clusters.
